The present disclosure will be further described with reference to the drawings and detailed description.
According to a first aspect of the present disclosure, an oil cooling filter arrangement is provided. Referring to fig. 1 to 8, the oil cooling filter device includes a housing 100 and a filter 200, wherein a filter chamber 130 is constructed in the housing 100, the filter 200 is installed in the filter chamber 130, a high temperature medium chamber 120 communicating with the filter chamber 130 is constructed in the housing 100, a high temperature medium inlet 101 communicating with the high temperature medium chamber 120, and a high temperature medium outlet 102 communicating with the filter chamber 130 are opened in the housing 100; the engine 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 passes through the high-temperature medium cavity 120 and extends out of the high-temperature medium cavity 120.
Through the above technical solution, that is, the engine oil cooling filter device provided by the present disclosure, engine oil enters the high temperature medium cavity 120 through the high temperature medium inlet 101, and is then filtered by the filter 200 in the filter cavity 130 and then discharged from the high temperature medium outlet 102, so as 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 the heat of the engine oil in the high-temperature medium chamber 120, the formed steam flows into the condensation section 310, the heat is emitted by the steam in the condensation section 310 through heat exchange with the external environment, and 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 into the evaporation section 320 under the action of gravity, so that a closed cycle is formed, and a large amount of heat is transferred from the high-temperature medium chamber 120 to the external environment, so that rapid and effective cooling is formed. In summary, the engine oil cooling filter device provided by the disclosure fully utilizes the heat conduction principle and the rapid heat transfer property of the phase change medium, and 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, where the condensation section 310 may be cooled in any suitable manner to transfer heat away. For example, in some embodiments, the condensing segment 310 of the heat pipe 300 may be directly exposed to the outside air, such that the condensing segment 310 directly exchanges heat with the outside air to transfer heat in the high temperature medium chamber 120 to the outside air.
Considering that the cooling effect of the condensation section 310 of the heat pipe 300 is easily affected by the outside air when the outside air temperature is high, the temperature difference between the condensation section 310 and the outside air temperature is small, which results in poor heat conduction effect of the heat pipe 300 and further affects the cooling and heat dissipation of engine oil. Thus, in some embodiments, a low temperature medium chamber 110 is configured in the housing 100, the low temperature medium chamber 110 and the high temperature medium chamber 120 are arranged at intervals from each other in 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 chamber 110, and the housing 100 is provided with a low temperature medium inlet 103 and a low temperature medium outlet 104 communicating with the low temperature medium chamber 110. In the embodiment of the present disclosure, the low temperature medium flows into the low temperature medium chamber 110 from the low temperature medium inlet 103 and flows out from the low temperature medium outlet 104 to form a flow path of the low temperature medium. The heat of the condensing section 310 is absorbed and taken away by the low-temperature medium, so that the temperature difference between the condensing 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 may be connected to an additional water circulation system, or the like, that is, another low-temperature medium may be used to absorb and take away heat of the condensation section 310 of the heat pipe 300.

Accordingly, in order to satisfy the high heat exchange efficiency of the oil cooling filter device of the present disclosure while reducing the manufacturing costs thereof, in some embodiments, as shown with reference to fig. 2, 3 and 6, a cylindrical partition 140 is coaxially disposed within the housing 100, an inner space of the cylindrical partition 140 is configured as a filter chamber 130, an annular partition 150 is coaxially connected between an outer side wall of the cylindrical partition 140 and an inner side wall of the housing 100, and the annular partition 150 partitions a space between the housing 100 and the cylindrical partition 140 into a first annular fluid space serving as the low temperature medium chamber 110 and a second annular fluid space serving as the high temperature medium chamber 120. Through setting up tube-shape baffle 140 and annular baffle 150 and the cooperation of casing 100 and constructing into low temperature medium chamber 110, high temperature medium chamber 120 and filter chamber 130, make the runner arrangement of this oil cooling filter device of this disclosure simple and practical, the structure is reliable, easily production, manufacturing cost is showing to reduce simultaneously.

By arranging the low-temperature medium cavity 110 as a blocked annular fluid space, the fluidity of the low-temperature medium in the low-temperature medium cavity 110 can be increased, so that the low-temperature medium can fully exchange heat with the condensation section 310 of the heat pipe 300, and the heat released by the condensation section 310 can be absorbed and taken away in time, so that the heat exchange efficiency is further improved.
To further improve the heat exchange efficiency of the engine oil cooling filter device of the present disclosure, in some embodiments, referring to fig. 3 and 5, the second annular fluid space is partitioned by a second stopper 170 connected between the cylindrical partition 140 and the housing 100 and connected to the annular partition 150, the high temperature medium inlet 101 is disposed at one side of the second stopper 170, and the cylindrical partition 140 is provided with a through hole 141 communicating the filter chamber 130 with the high temperature medium chamber 120 at the other side of the second stopper 170.

The heat pipe has a cavity with a hollow negative pressure and is filled with volatile working liquid, which is known to those skilled in the art, and is not described herein. And when the gravity assisted heat pipe is in use, the condensation section 310 is located above the evaporation section 320, so that the working liquid flows back into the evaporation section 320 under the action of gravity after the condensation section 310 condenses, and therefore, in the embodiment of the disclosure, the low temperature medium chamber 110 is located above the high temperature medium chamber 120, so as to facilitate the heat conduction process of the working liquid in the gravity assisted heat pipe. In the embodiment of the disclosure, the cross section of the evaporation section 320 is larger than that of the condensation section 310, so that the heat exchange area between the evaporation section 320 and engine oil can be increased, and the heat exchange efficiency is increased; meanwhile, the cross section of the evaporation cavity 380 is larger than that of the condensation cavity 370, so that working liquid is easy to accumulate in the condensation cavity 370 for rapid condensation after the evaporation cavity 380 is heated and vaporized, the phase change process can be accelerated, and the heat conduction capacity is enhanced.
To further increase the phase change process inside the heat pipe and increase its heat transfer capability, in some embodiments, referring to fig. 7, the junction of the evaporation cavity 380 and the condensation cavity 370 has a tapered structure 390 tapering from the evaporation cavity 380 to the condensation cavity 370. The tapered structure 390 facilitates the rapid flow of working fluid into the condensing chamber 370 for condensation after vaporization, accelerating the phase change process.
In some embodiments, referring to fig. 5 and 7, the inner sidewall of the heat pipe 300 has the flow guide grooves 301 arranged at uniform intervals in the circumferential direction, and the flow guide grooves 301 extend from the evaporation chamber 380 to the condensation chamber 370 in the axial direction. The diversion trench 301 has a diversion function, and is easy to guide the condensed working liquid to uniformly flow into the evaporation cavity 380, so that the evaporation section 320 is uniformly heated. Meanwhile, the rib between the adjacent guide grooves 301 may reinforce the structural strength of the heat pipe 300.
