Description

  The present invention relates to a radiator cooling liquid injection method and a radiator cooling liquid injection adapter used for injecting a radiator cooling liquid (LLC) into a radiator.

  As shown in FIG. 10, the radiator 60 is a radiator that dissipates the heat of the radiator coolant that has absorbed the heat of the engine 61 and has increased in temperature. In FIG. 10, reference numeral 62 denotes a radiator coolant recovery hose for recovering the radiator coolant from the engine coolant flow path. In the vicinity of the radiator 60, there is a reserve tank 63 for storing the radiator coolant. The radiator 60 is configured such that when the temperature in the radiator 60 increases and the pressure of the radiator coolant increases, the radiator coolant appropriately overflows from the radiator 60 and is collected in the reserve tank 63. Further, the reserve tank 63 has a function of appropriately supplying the radiator coolant to the radiator 60 when the temperature of the radiator 60 is lowered and the pressure of the radiator coolant is decreased. The reserve tank 63 is provided with a safety valve, and when the pressure in the reserve tank 63 rises above a certain value, the reserve tank 63 is appropriately opened to the atmosphere.

  The radiator coolant injecting section 70 for injecting the radiator coolant is provided on the radiator 60 side. As shown in FIG. 11A, the radiator coolant injection section 70 surrounds the radiator coolant injection port 71 and the radiator coolant injection port 71, and the outer wall 72 a is more than the radiator coolant injection port 71. A raised overflow receiving groove 72 is provided. The outer wall 72a of the overflow receiving groove 72 is formed with a channel hole 73 that communicates with a reserve water channel 64 (see FIG. 10) that returns the radiator coolant to the reserve tank 63 when the radiator coolant overflows. Has been. The radiator coolant injection unit 70 is provided with a radiator valve (safety valve) after the injection of the radiator coolant is completed.

  When the radiator coolant is injected into the radiator 60, the radiator coolant is fully injected into the radiator coolant system, while the radiator coolant is quantitatively injected into the reserve tank 63 to a certain height. For example, as shown in FIG. 11B, this operation is performed by using the radiator coolant injection device 80 to suck air from the radiator coolant system to make the inside of the radiator coolant system into a vacuum state. Inject the radiator coolant into the radiator coolant system. When the radiator coolant system is once evacuated and the radiator coolant is supplied to the radiator coolant system, the radiator coolant spreads to every corner of the radiator coolant system.

  A radiator coolant injecting device 80 for injecting a radiator coolant into the coolant system of the radiator is, for example, a radiator coolant injecting device main body 81 connected to the upper end portion of the overflow receiving groove 72 as shown in FIG. (Outer cylinder) and a nozzle 82 (inner cylinder) that moves back and forth with respect to the radiator coolant injection device main body 81. As shown in FIG. 11C, the nozzle 82 moves back and forth with respect to the radiator coolant injection device main body 81 so as to be surely pressed against the radiator coolant injection port 71. The tip 83 is shaped so as to be in close contact with the radiator coolant inlet 71.

  In this radiator coolant injection device 80, as shown in FIG. 11 (b), the radiator coolant injection device main body 81 (outer cylinder) is connected to the radiator coolant injection portion 70 to the outer wall 72a of the overflow receiving groove portion 72. . Next, as shown in FIG. 11 (c), the tip 83 of the nozzle 82 (inner cylinder) is pressed against the radiator coolant inlet 71 to close the radiator coolant system. Next, a vacuum pump (not shown) connected to the nozzle 82 (inner cylinder) of the radiator coolant injecting apparatus 80 is driven to suck air from the radiator coolant system and to evacuate the radiator coolant system (I ). The radiator coolant injection device 80 drives a radiator coolant supply pump (not shown) simultaneously with the operation of evacuating the coolant system of the radiator so that the nozzle 82 (inner cylinder) and the radiator coolant injection device main body 81 ( The radiator coolant is supplied to the outer cylinder), and the radiator coolant is quantified to the reserve tank 63 through the reserve water channel 64 (see FIG. 10) from the channel hole 73 provided in the outer wall 72a of the overflow receiving groove 72. Supply (II). Next, the radiator coolant injecting device 80 drives a radiator coolant supply pump (not shown) connected to the nozzle 82 (inner cylinder), so that the radiator coolant system that is in a vacuum state from the nozzle 82 (inner cylinder) becomes a coolant system. Fill the radiator coolant fully (III).

  In this manner, the radiator coolant is fully injected into the radiator coolant system, while the radiator coolant is quantitatively injected into the reserve tank 63 to a certain height.

  Various operations of the radiator coolant injecting device 80 may be controlled by a control device (not shown) so that the radiator coolant injecting device 80 is automatically performed after the radiator coolant injecting device 80 is set in the radiator coolant inlet.

  By the way, in the structure of the radiator, as shown in FIG. 12, the radiator 60a is sealed without providing the radiator coolant injection part 70 in the radiator 60a, and the flow path on the engine 61 side of the coolant system and the reserve tank 63 are connected. There is also a so-called completely sealed radiator 60 a in which a coolant circulation hose 65 for circulating a radiator coolant is provided between them, and a radiator coolant injection part 90 is provided in the reserve tank 63.

  The completely sealed radiator 60 a is configured such that the radiator coolant including the reserve tank 63 is always supplied by a coolant circulation hose 65 provided so as to communicate between the flow path on the engine 61 side of the coolant system and the reserve tank 63. It is configured to circulate. In this completely sealed radiator 60a, even when bubbles are generated by cavitation in the radiator 60a, the radiator coolant circulates in the reserve tank 63. Therefore, as shown in FIG. 63.

  Further, the completely sealed radiator 60a is provided with the coolant circulation hose 65 between the flow path on the engine 61 side of the coolant system and the reserve tank 63, so that the pressure of the radiator coolant on the engine 61 side is reduced. In the case of a drop, the air stored in the upper part of the reserve tank 63 serves as a damper, and the radiator coolant is supplied from the reserve tank 63 through the coolant circulation hose 65 to the flow path on the engine 61 side. . As a result, the pressure of the coolant system of the radiator (especially the pressure in the flow path on the engine 61 side) can be prevented from significantly decreasing, the cooling function of the engine 61 by the radiator 60a can be maintained, and the reliability of the engine 61 can be maintained. Can be improved.

  In the present specification, the structure of the previously described radiator 60 (FIG. 10) is referred to as a simple sealed radiator 60, as distinguished from the completely sealed radiator 60a (FIG. 12).

As a method of injecting the radiator coolant into the completely sealed radiator 60a, the technique described in Japanese Patent Laid-Open No. 7-137703 (Patent Document 1) can be applied. In the device described in the publication, first, as shown in FIG. 14A, an injection device 100 constituting a liquid injection device is attached to a container A that forms an accommodation space S. The injection device 100 includes a circulation pipe 102 that is communicated with a vacuum pump and a liquid supply source (not shown) that are passed through a lid 101 that closes the mouth C of the container A, and an openable pipe 103 that can be opened and closed. Then, as shown in FIG. 14B, the inside of the storage space S of the container A is evacuated through the distribution pipe 102, and then the liquid is supplied into the storage space S through the distribution pipe 102 as shown in FIG. 14C. Fill L. Next, as shown in FIG. 14 (d), after opening the open pipe 103 to open the accommodation space S to the atmosphere, the liquid L is sucked through the flow pipe 102 while introducing the atmosphere, and this suction is performed in a predetermined manner. By performing this time, as shown in FIG. 14E, the injection is completed so as to leave a predetermined amount of the liquid L in the storage space S of the container A. (Patent Document 1)
