Description

The solution relates to heat transfer, elements of heat exchange devices, in particular tubular, and can be effectively used in cooling machines, especially engines, in particular, for liquid cooling, and primarily to devices for cooling charge air.

In an internal combustion engine, about a third of the fuel energy is converted into useful work. The effectiveness of such a conversion largely depends on the cooling of the working fluid entering the engine cylinders. It is carried out in two ways: by direct cooling of the air and indirectly by cooling with a liquid. When the engine is equipped with a boost system, the efficiency depends on the temperature of the charge air, the value of which depends on the mentioned factors. To date, the theoretical foundations for the design of radiators have been developed (see, for example, R. Bussien Automobile reference book, vol. 2, Mashgiz, M., 1959, pp. 156-163), which can be used in the calculation of charge air cooling devices , it is rational to use known types and designs of radiators (see 163-166).

Heat dissipation by the radiator is a power-law function of the volume of air blown through it. In most cases, the fan is installed in the immediate vicinity of the water cooling radiator. As for the charge air radiator, its location relative to the engine and fan is very arbitrary. A known cooling system of a turbo-piston engine of a vehicle, consisting of a fan, a boost unit with an air cooler, a water radiator (see the book Internal combustion engines under the general editorship of A.S. Orlin, M.G. Kruglova - M., Mechanical Engineering, 1985 , p. 456). Due to irrevocable heat loss to the atmosphere, engine efficiency is low.

The cooling systems of the working fluid of internal combustion engines are widely known, containing fluid cooling units and a charge air heat exchanger (Kulikov Yu.A. Cooling system of power plants of diesel locomotives M, 1988, pp. 7-13). To increase the efficiency of the engine in these systems regulate the temperature of the coolant and change the air flow to blow radiators.

Coolers are provided in the power supply systems of turbo-charged internal combustion engines (see, for example, US 2388350, 2540916, 2474203, 2477668, 2464548, 2491372, 2433326, 2518660, 2474018, 2487049, 2627370, 2703560, 2877622, 2952958, 31023966, 3102381 , 3173242, 3143849, 3232042, 3303348 and 3355877; DE 953129, 1003505 and 1220199). In none of the above cases there is a description of the design of the cooler, which is important, despite the fact that the cases considered are those in which the regulatory body responds to several parameters of the working medium or engine operation, in particular, the parameter of the gaseous working medium of the engine. It should be noted that when describing the turbocharging method according to US 3336911, an indicator diagram of the engine is shown and the influence of the cooler is disclosed, as well as in the system according to US 3257797.

In pressurization systems according to US 2195082, 2306277, 2359615, 2356370, 2355759, 2362493, 2443717, 2428708, 2372467, 2417363 and 3091228, the cooler is placed so that it does not receive cooling air from the fan. The cooling efficiency in the deflectors according to DE 1476402, as well as UK 1326328 and 1334816, largely depends on the location of the fan. In engines according to US 2195082, 2306277 and 2518062, cooling of the charge air is provided with a fin radiator.

The device for cooling charge air according to SU 297787 contains a heat exchanger made in the fan housing with a developed cooling surface. The device for cooling a diesel engine according to SU 498915 contains heat exchangers, while the accuracy of regulating the temperature of the charge air is ensured by the installation of a thermostat and an inductor. The performance of both the cooling system according to SU 714030 and the cooling device according to SU 798335 depends on the choice of parameters of the fan, mixing chamber and channels. The cooling system of a supercharged internal combustion engine according to SU 1333796 is equipped with an additional fan. An air supply control unit is provided in an internal combustion engine according to SU 1483069 and in a diesel installation according to SU 1815360, and an additional heat exchanger is provided in an internal combustion engine according to SU 1539353. The cooler sections are united by a common prefabricated manifold and have separate distributing manifolds for a V-shaped turbocharged engine according to RU 2083855.

Known cooling systems for internal combustion engines according to SU 240157, in which the outlet of the turbocharger is connected through an intermediate air-air cooler to the intake manifold of the engine, and the refrigerator fan is kinematically connected to a gas turbine. The internal combustion cooling system according to US 3854459 contains a fan and louvers that regulate the flow of air, while at least part of the channel from the louvers to the fan is limited by a casing having a slit. Such systems are complex and expensive to manufacture. The cooling system according to FR 2260690 is somewhat simpler, but control of the charge air temperature is difficult. The efficiency of cooling systems according to SU 603759 and 732567, as well as in a device for regulating the charge air temperature of an internal combustion engine according to SU 1726810, has been increased.

In vehicles (US 1979191, 2242494, 2058228, 2092040, 2789647 and 4706461; JP 60-156370, 60-254372; SU 1770162 and 1800069), the cooling system is made taking into account their layout. Cooling systems according to US 2117040, 2228345; DE 755632; JP 6029811; SU 1236130, 1761968; RU 17064, 23085 and 23673 have two radiators, placed taking into account the layout of the vehicle. The cooling module according to DE 19731999 is supported on two racks mounted on a vehicle. The radiator assembly of the ICE cooling system according to RU 21624 is equipped with damping gaskets, and each base plate has a second fastening means. In the main truck according to US 4736727, a single fan casing surrounds the cavity between the fan and the heat exchangers and directs the air sucked through both heat exchangers to the fan.

In engines according to US 1958156, 2118484, 2086441, 2084940, 2136605, 2327491, 2498001, 2741234 and 3255740; DE 754272, 908678, 970300, 1089212, 1140018 and 1270885; FR 1258807; SU 1211429, 1280147, 1495464, 1553744, 1657687, 1740717, 1710795, 1772368 and 1826606; RU 2064596 and 49581 there are options for performing a radiator from two sections. The internal combustion engine according to US 1958156 is equipped with a traditional liquid cooling system and contains numerous nozzles. The engine cooling system according to US 1980811 is even more complex, and the system according to US 2498001 is multi-sectional, as are the coolers according to SU 1571282, 1546683, as well as RU 2094243. The cylindrical cooler is mounted coaxially to the turbocharger and is equipped with spiral plates (see, for example, US 3257069) . This design of the cooler is difficult, and placement is most often impossible. Rationally placed cooler in the engine according to US 3027706, while it is a tubular design with plates. A charge air cooler containing skeleton plates to which tubes and tapes are attached, as well as tanks with outlets, and fastening means (see, for example, US 2451132). The cooler body has a flange mount to the engine crankcase. The cooler tanks are made in a molded case with multiple bolting to the skeleton and are connected to the cooling system, while one of the skeletons has a separate mount to the adapter. The design is complex, while high costs are inevitable when operating the cooler. In essence, not only the use of a cooler in relation to another engine is excluded, but also a change in the relative position of the cooler and the engine. It should be noted that a liquid medium was used in these coolers, which is not always rational.

The radiator block of an internal combustion engine according to RU 36451 contains a radiator and an auxiliary radiator mounted on it either frontally or from the rear. In this case, the sequential placement of radiators reduces at least the efficiency of one of them. The radiator block according to RU 45817 includes sections, manifold chambers with end caps and longitudinal shelves, as well as sidewalls fastened with shelves, while lining plates are installed on the sides of the covers on the front and back sides, and under them are corners fastened with shelves and between themselves, to the edges of the sidewalls from the front and back sides are attached strips placed at the corners and fastened to the corners, with shelves and with overlays. With such a block, its sections are adjacent sidewalls, and their location may be ineffective for one of the sections.

Although the mentioned designs of coolers, their components and parts are very diverse, their use will not allow to obtain an efficiently functioning design of the charge air cooler of an internal combustion engine.

The radiator block containing the supporting plates of the skeleton, tubes and tapes, as well as tanks with nozzles, and fastening means (see, for example, US 4916902) is the closest analogue. The plates of the section cores are placed relative to each other with an offset, which complicates their installation and securing the shape of the section tanks is difficult, and this leads to additional costs in production due to differences in their shape and due to the attachment of pipes to them. The fastening of the unit is structurally unreliable, especially due to the placement and drive of the blinds, and this leads to high costs during operation of the charge air cooler. In essence, the use of such a block as applied to another engine, as well as a change in the relative position of its units, is excluded.

The task is to simplify the manufacture, installation and operation of the radiator block.

The achievement of the technical result, namely, the simplification of the manufacture, installation and operation of the radiator block is ensured by the rational execution of the placement and connection of its elements.

To do this, in the block of radiators, consisting of a charge cooler and a radiator containing cores with tubes and cooling plates, tanks with pipes, as well as fasteners, the cores of each of the heat exchangers are located between the tanks of the other.

The core of the charge air cooler is divided into peninsulas between which there is a screed.

The ratio of the heights of the cooling plate and the radiator tube is 2.6-3.7.

The charge air cooler and the radiator are connected by a bolt and nut.

figure 3 is a view of the radiator;

figure 4 - peninsula;

Fig.7 - placement of heat exchangers;

Fig. 8 shows a radiator plate and tube;

The block contains a charge cooler 1 and a radiator 2 (Fig. 1). The cooler 1 contains a skeleton 3 (Fig. 2) and a tank 4 (Fig. 1). The skeleton 3 is made of peninsula 5 and coupler 6. The cooler 1 has nozzles 7, pins 8 and an arm 9 (Fig. 1). Radiator 2 contains a skeleton 10 (figure 3), nozzles 11 and brackets 12, tanks 13. The peninsula 5 contains tubes 14, fixed to the support plates 15 (figure 4). Between the tubes 14 placed cooling plate 16 (figure 4). In the tubes 14 installed cooling plate 17 (figure 5). The skeleton 10 contains support plates 18, amplifiers, amplifiers 19, cooling plates 20 and tubes 21 (Fig.6). Thus, the radiator block contains skeletons with tubes and cooling plates, as well as fasteners. The core 3 of the cooler 1 is placed between the tanks 13 of the radiator 2 (Fig.7), and the core 10 of the radiator 2 is located between the tanks 4 of the cooler 1. Thus, the core of the heat exchangers are mutually located between the tanks of each other.

The mutual arrangement of the cores 3 and 10 of the heat exchangers 1 and 2 between the tanks of each other will achieve a technical result, namely, to simplify the manufacture, installation and operation of the radiator block.

This result is facilitated by the separation of the skeleton 3 into peninsulas 5 and their connection with a screed 6.

The height of the cooling plate 20 hg (Fig. 8) to the height of the tube 21 ht is 2.6-3.7, which ensures the greatest heat transfer at the lower value and the optimal passage of air and liquid at the upper.

The cooler 1 and radiator 2 are connected by a bolt 22 and a nut 23, which is simple.

When the engine is running, the charge air passes through the inlet pipe 7, then enters the tank 4, which allows it to continue moving through the tubes 14 and proceed to the outlet pipe.

The cooled coolant (antifreeze) enters the tank 13, moving through the tubes 21 goes into the cooling system.

Due to the presence of numerous tubes 21 and cooling plates 20, intense heat transfer of heat to the air supplied to the elements of the block occurs.
