Description

Heat pipe oil cooler for vehicle

technical field

The utility model relates to an engine oil cooler, in particular to a heat pipe type oil cooler for vehicles which is widely used in power machinery such as vehicles, generator sets, and air compressors.

Background technique

Engines are used to provide power for power machinery such as vehicles and generator sets, while the lubrication and cooling of components such as engines and gearboxes are done by engine oil. With the development of modern high-power engines, the heat carried by engine oil continues to increase, and the problem of heat dissipation of engine oil has become increasingly prominent. And the oil temperature must be controlled below 120°C. In order to improve the mechanical efficiency, the oil temperature should not be lower than 100°C. The existing oil cooler is becoming more and more unsuitable. In view of the excellent thermal conductivity of the heat pipe, a heat pipe type oil cooler is introduced. Making full use of air cooling can well solve this technical problem.

Utility model content

The purpose of this utility model is to provide a heat pipe type oil cooler for a vehicle in view of the above-mentioned defects in the prior art, which fully utilizes the air to cool the oil.

The technical solution adopted by the utility model is: a heat pipe oil cooler for vehicles, which is mainly composed of an integral copper-aluminum composite fin heat pipe, an oil inlet, an oil cavity, and an oil outlet; The finned heat pipes are evenly arranged on the oil chamber.

Further, the integral copper-aluminum composite fin heat pipe includes a heat pipe evaporation section, a heat pipe condensation section, fins and a working medium. The condensing section of the heat pipe and the cold-rolled fins are integrally formed, and the working medium is in the inner space of the evaporating section of the heat pipe and the condensing section of the heat pipe. The evaporating section of the heat pipe is inserted into the oil chamber, and the condensing section of the heat pipe is outside the oil chamber.

The utility model has the following technical effects:

1. The utility model uses the upwind of the vehicle to cool the engine oil, so there is no need for coolant cooling, there is no secondary cooling problem, and no additional pump work is consumed.

2. The cold and heat sources in the utility model are separated by the tube shell without direct contact, and the energy is transferred through the superconducting heat pipe. If some heat pipes are damaged, the normal operation of the heat pipe oil cooler will not be affected.

3. If the utility model adopts the controllable heat pipe, the heat pipe oil cooler can be controlled to start working at 100°C, so that the oil is always kept within the optimum working temperature range.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings, but not as a limitation of the utility model.

As shown in Figure 1 and Figure 2, the vehicle heat pipe oil cooler of the present invention includes an integral copper-aluminum composite fin heat pipe 1, an oil inlet 2, an oil chamber 3, and an oil outlet 4, and an integral copper-aluminum composite fin heat pipe 1, an oil inlet 2, an oil chamber 3, and an oil outlet 4 The finned heat pipes 1 are evenly arranged on the oil cavity 3 . The cold and hot fluids of the machine oil cooler are separated by the oil chamber 3, the oil chamber 3 is high-temperature machine oil, and the oil chamber 3 outside is windward cooling air.

As shown in FIG. 3 , the integral copper-aluminum composite fin heat pipe 1 includes a heat pipe evaporation section 5 , a heat pipe condensation section 6 , fins 7 and a working medium 8 . The heat pipe condensation section 6 and the fins 7 are integrally formed by cold rolling, with small contact thermal resistance and high strength. The heat pipe evaporation section 5 is connected to the heat pipe condensation section 6. Large heat absorption area. The working medium 8 works in the internal space of the heat pipe evaporation section 5 and the heat pipe condensation section 6 . The evaporating section 5 of the heat pipe is inserted into the oil chamber 3 , and the condensing section 6 of the heat pipe is outside the oil chamber 3 .

The working process of the utility model is: when the high-temperature engine oil enters the oil cavity 3 of the utility model from the oil inlet 2, after the heat pipe evaporation section 5 absorbs heat, the working medium water 8 in the tube evaporates and vaporizes, and the steam evaporates under a small pressure difference. Under the action, it rises to the condensation section 6 of the heat pipe, and the windward cooling air enters in the direction of the vertical arrow 9 as shown in Figure 2, and the heat is transferred to the cooling air through the condensation section 6, and the water vapor condenses into water, which flows back to the heat pipe under the action of gravity The evaporating section 5 continuously reciprocates in this way, so that the windward cooling air can take away the heat of the high-temperature engine oil through the heat pipe, so as to quickly cool the high-temperature engine oil and ensure that the engine oil is within the optimum operating temperature range, which is very beneficial to the engine.
