[0030] Reference is made below to Figure 1 and Figure 2 describe a headlight assembly 10 according to an embodiment of the present utility model.
[0031] As Figure 1 and Figure 2 shown, a headlight assembly 10 according to an embodiment of the present utility model is for a vehicle. The vehicle includes a thermal management system 20. The thermal management system 20 includes a compressor 202, a condenser 204, and an evaporator 203. One end of the condenser 204 is connected to the exhaust port of the compressor 202, one end of the evaporator 203 is connected to the suction port of the compressor 202, the other end of the evaporator 203 and the other end of the condenser 204 are connected, and a return air pipe 201 is provided between the compressor 202 and the evaporator 203. The headlight assembly 10 exchanges heat with the return air pipe 201.
[0032] It should be noted that the above thermal management system 20 is in a refrigeration working condition. The thermal management system 20 further includes an expansion valve 205 and a fan 206. The expansion valve 205 is provided between the evaporator 203 and the condenser 204 and is connected to both the evaporator 203 and the condenser 204. There are two fans 206, which are respectively arranged corresponding to the evaporator 203 and the condenser 204, so as to facilitate improving the air flow speed and the heat exchange efficiency between the evaporator 203 and the condenser 204.
[0033] It can be understood that the high-temperature and high-pressure gaseous refrigerant first enters the condenser 204 from the compressor 202 to exchange heat with the outside air, and then flows to the expansion valve 205 for throttling and pressure reduction. At this time, the gaseous refrigerant becomes a low-temperature and low-pressure liquid refrigerant, and then enters the evaporator 203 to exchange heat with the air inside the vehicle, making the refrigerant become gaseous, and then enters the return air pipe 201. At this time, the temperature of the refrigerant in the return air pipe 201 is still relatively low, so that the temperature of the outer peripheral wall surface of the return air pipe 201 is 0 - 30 °C. For the temperature when the headlight assembly 10 is working, the temperature of the outer peripheral wall surface of the return air pipe 201 is relatively low, and the headlight assembly 10 can be cooled. Thus, by the headlight assembly 10 exchanging heat with the return air pipe 201, the cooling of the headlight assembly 10 is realized, and the thermal management system 20 operates stably and reliably, so that the cooling of the headlight assembly 10 is reliable.
[0034] Among them, through the heat exchange between the headlight assembly 10 and the return air pipe 201, the cooling of the headlight assembly 10 is realized, and the original vehicle heat management system 20 is used for cooling, without setting additional fan devices and liquid cooling components, with low noise and low cost.
[0035] Furthermore, through the heat exchange between the headlight assembly 10 and the return air pipe 201, the refrigerant can be further superheated, increasing the superheat degree of the refrigerant return air, thereby reducing the situation of liquid refrigerant entering the compressor 202, avoiding the liquid slugging phenomenon of the compressor 202, and improving the service life of the compressor 202.
[0036] According to the headlight assembly 10 of the embodiment of the present invention, one end of the condenser 204 is connected to the exhaust port of the compressor 202, one end of the evaporator 203 is connected to the suction port of the compressor 202, the other end of the evaporator 203 and the other end of the condenser 204 are connected, a return air pipe 201 is provided between the compressor 202 and the evaporator 203, and the headlight assembly 10 exchanges heat with the return air pipe 201 to realize the cooling of the headlight assembly 10, and the original vehicle heat management system 20 is used for cooling, without setting additional fan devices and liquid cooling components, with low noise and low cost, and the cooling of the headlight assembly 10 is reliable.
[0037] In some embodiments of the present invention, as Figure 1 shown, the headlight assembly 10 includes: a headlight body 1 and a heat conducting plate 2. The heat conducting plate 2 is arranged between the headlight body 1 and the return air pipe 201. The heat conducting plate 2 is connected to the headlight body 1 and is adapted to exchange heat with the return air pipe 201. It can be understood that the return air pipe 201 is connected to the heat conducting plate 2, so that the headlight assembly 10 can be fixed relative to the return air pipe 201. The setting of the heat conducting plate 2 can, on the one hand, increase the heat exchange efficiency between the headlight body 1 and the return air pipe 201, thereby improving the cooling and refrigeration efficiency of the headlight assembly 10, and on the other hand, can better facilitate the connection between the headlight body 1 and the return air pipe 201.
[0038] In some embodiments of the present invention, the thickness of the heat conducting plate 2 is 0.4 mm - 5 mm, such as 0.4 mm, 1 mm, 2 mm or 5 mm, etc. Thus, the thickness of the heat conducting plate 2 is appropriate. On the one hand, the heat conducting plate 2 has sufficient thickness to ensure the structural strength of the heat conducting plate 2, thereby ensuring the installation stability between the headlight assembly 10 and the return air pipe 201. On the other hand, it avoids the heat conducting plate 2 being too thick, which is beneficial to the economy and light weight of the headlight assembly 10.
[0039] In some embodiments of the present utility model, the length of the heat conduction plate 2 along the length direction of the return air pipe 201 is 200 mm - 500 mm, such as 200 mm, 300 mm, 400 mm or 500 mm, etc. Thus, on the one hand, the heat conduction plate 2 has sufficient length, ensuring sufficient heat conduction area between the heat conduction plate 2 and the return air pipe 201, thereby ensuring the heat exchange efficiency and the refrigeration efficiency. On the other hand, it avoids the heat conduction plate 2 from being too long, which is beneficial to the economy and light weight of the headlight assembly 10.
[0040] In some embodiments of the present utility model, the heat conduction plate 2 is an aluminum part, a copper part, a stainless steel part or a silicon carbide part. It can be understood that the aluminum part, the copper part, the stainless steel part or the silicon carbide part has good thermal conductivity, thereby further improving the thermal conductivity of the heat conduction plate 2, further improving the heat exchange efficiency between the headlight body 1 and the return air pipe 201, and further improving the cooling and refrigeration efficiency of the headlight assembly 10.
[0041] In some embodiments of the present utility model, as Figure 1 shown, the return air pipe 201 is a cylindrical pipeline, and the heat conduction plate 2 is an arc-shaped plate protruding away from the return air pipe 201. The arc-shaped surface of the heat conduction plate 2 facing the return air pipe 201 is attached to the outer peripheral wall surface of the return air pipe 201. Thus, the heat conduction plate 2 can be better attached to the return air pipe 201. On the one hand, it is convenient for the installation between the heat conduction plate 2 and the return air pipe 201. On the other hand, it is beneficial to the full contact between the heat conduction plate 2 and the return air pipe 201, thereby further improving the heat exchange efficiency between the headlight body 1 and the return air pipe 201, and further improving the cooling and refrigeration efficiency of the headlight assembly 10.
[0042] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, along the length direction of the return air pipe 201, a part of the return air pipe 201 opposite to the heat conduction plate 2 extends in a meandering manner. Thus, the length of the corresponding part of the return air pipe 201 to the heat conduction plate 2 is increased, thereby increasing the contact area (heat conduction area) between the return air pipe 201 and the heat conduction plate 2, and further improving the heat exchange efficiency between the headlight body 1 and the return air pipe 201, and further improving the cooling and refrigeration efficiency of the headlight assembly 10.
[0043] In some embodiments of the present utility model, as Figure 1 and Figure 2As shown, the heat conducting plate 2 is provided with an installation groove 21, and the return air pipe 201 is embedded in the installation groove 21. Thus, on the one hand, the heat conducting plate 2 can be better fixed and installed on the return air pipe 201, and on the other hand, through the full contact between the outer peripheral wall of the return air pipe 201 and the inner peripheral wall of the installation groove 21, the contact area between the heat conducting plate 2 and the return air pipe 201 is increased, thereby further improving the heat exchange efficiency between the headlight body 1 and the return air pipe 201, and further improving the cooling efficiency of the headlight assembly 10.
[0044] Further, as Figure 1 and Figure 2 shown, along the length direction of the return air pipe 201, a part of the return air pipe 201 opposite to the heat conducting plate 2 extends in a meandering manner, and the installation groove 21 extends in a meandering manner along the length direction of the return air pipe 201. Thus, it is convenient for the return air pipe 201 to be embedded in the installation groove 21.
[0045] In some embodiments of the present invention, the heat conducting plate 2 is connected to the headlight body 1 through heat conducting glue; thus, on the one hand, the connection reliability between the heat conducting plate 2 and the headlight body 1 is increased, and on the other hand, the heat conduction efficiency between the heat conducting plate 2 and the headlight body 1 is increased, thereby further improving the heat exchange efficiency between the headlight body 1 and the return air pipe 201, and further improving the cooling efficiency of the headlight assembly 10.
[0046] In some embodiments of the present invention, the heat conducting plate 2 is connected to the return air pipe 201 through heat conducting glue. Thus, on the one hand, the connection reliability between the heat conducting plate 2 and the return air pipe 201 is increased, and on the other hand, the heat conduction efficiency between the heat conducting plate 2 and the return air pipe 201 is increased, thereby further improving the heat exchange efficiency between the headlight body 1 and the return air pipe 201, and further improving the cooling efficiency of the headlight assembly 10.
