The present disclosure will be further described with reference to the accompanying drawings and detailed description.

According to a first aspect of the present disclosure, an oil cooling filter device is provided. Referring to fig. 1 to 8, the oil cooling filter device includes a housing 100 and a filter 200, a filter cavity 130 is configured in the housing 100, the filter 200 is installed in the filter cavity 130, a high temperature medium cavity 120 communicated with the filter cavity 130 is configured in the housing 100, the housing 100 is opened with a high temperature medium inlet 101 communicated with the high temperature medium cavity 120 and a high temperature medium outlet 102 communicated with the filter cavity 130; the oil cooling filter device further comprises a heat pipe 300, wherein an evaporation section 320 of the heat pipe 300 is arranged in the high-temperature medium cavity 120, and a condensation section 310 penetrates through the high-temperature medium cavity 120 and extends out of the high-temperature medium cavity 120.

By the technical scheme, namely the engine oil cooling and filtering device provided by the disclosure, engine oil enters the high-temperature medium cavity 120 through the high-temperature medium inlet 101, is filtered by the filter 200 in the filter cavity 130 and then is discharged from the high-temperature medium outlet 102 to form a flow path of the high-temperature medium; meanwhile, the working fluid in the evaporation section 320 of the heat pipe 300 evaporates after absorbing heat of engine oil in the high temperature medium cavity 120, the formed steam flows into the condensation section 310, the steam in the condensation section 310 dissipates the heat through heat exchange with the external environment, meanwhile, the steam in the condensation section 310 is condensed into the working fluid again after releasing the heat, and the working fluid flows back to the evaporation section 320 under the action of gravity, so that a closed cycle is formed, a large amount of heat is transferred to the outside from the high temperature medium cavity 120, and quick and effective cooling is formed. In conclusion, the engine oil cooling and filtering device provided by the disclosure makes full use of the heat conduction principle and the rapid heat transfer property of the phase change medium, the heat conduction capability of the metal heat conduction plate in the prior art is far exceeded, and the heat exchange efficiency is remarkably improved.

The working fluid in the evaporation section 320 absorbs heat and evaporates and then flows into the condensation section 310, and the condensation section 310 may be cooled in any suitable manner to transfer heat. For example, in some embodiments, condenser section 310 of heat pipe 300 may be directly exposed to the outside air, and condenser section 310 may directly exchange heat with the outside air to transfer heat in high temperature medium chamber 120 to the outside air.

Considering that the condensing section 310 of the heat pipe 300 is directly placed in the outside air, the cooling effect is easily affected by the outside air temperature, for example, when the outside air temperature is higher, the temperature difference between the condensing section 310 and the outside air temperature is smaller, which results in the heat conduction effect of the heat pipe 300 becoming worse, and further affects the cooling and heat dissipation of the engine oil. Therefore, in some embodiments, the housing 100 is configured with a low temperature medium cavity 110 therein, the low temperature medium cavity 110 and the high temperature medium cavity 120 are arranged at an interval from each other along an axial direction along which the heat pipe 300 extends, and the condensation section 310 of the heat pipe 300 is disposed in the low temperature medium cavity 110, and the housing 100 is opened with a low temperature medium inlet 103 and a low temperature medium outlet 104 communicated with the low temperature medium cavity 110.

The heat of the condensation section 310 is absorbed and taken away by the low-temperature medium, so that the temperature difference between the condensation section 310 and the low-temperature medium can be kept consistent by controlling the temperature of the low-temperature medium, and the influence of the temperature change of the external environment is avoided. And the phase change process in the heat pipe can be accelerated by reducing the temperature of the low-temperature medium, so that the heat exchange efficiency is improved. The low-temperature medium may be engine coolant, or an additional water circulation system or the like may be connected, that is, another low-temperature medium is used to absorb and remove heat from the condensation section 310 of the heat pipe 300.
