Description

Technical Field

[0002] With the improvement of people's living standards, air conditioners have become an indispensable electrical appliance in people's daily lives. The compressor is one of the most important components of an air conditioner. When the air conditioner is operating at high temperatures, the compressor's minimum operating frequency is set at 35Hz due to the maximum pressure limit. When the compressor is in a high-temperature environment (e.g., 55℃), its operating frequency is limited to 35Hz due to exhaust protection or external coil protection. However, even if the compressor operates at 35Hz, the entire unit will eventually shut down due to exhaust protection or external coil protection. Therefore, how to improve compressor heat dissipation has become an urgent problem to be solved. Utility Model Content

[0040] The compressor 100 assembly 10 of this utility model embodiment is described below with reference to the accompanying drawings.

[0041] like Figures 1-5 As shown, the compressor 100 assembly 10 of this utility model embodiment includes a compressor 100 and a heat dissipation device 200.

[0042] The heat dissipation device 200 includes a heat spreader 210, a heat sink 220, and a sintered heat pipe 230. The heat spreader 210 is disposed on the compressor 100 and is configured to conform to the outer surface of the compressor 100 so that the heat generated by the compressor 100 during operation can be evenly conducted to the heat spreader 210, providing a prerequisite for effective heat dissipation of the compressor 100.

[0043] Multiple sintered heat pipes 230 are used, each connected between the heat spreader 210 and the heat sink 220 to conduct heat from the heat spreader 210 to the heat sink 220. Heat is conducted from one end of the sintered heat pipe 230 to the other end, rapidly transferring heat from the heat spreader 210 to the heat sink 220, where it is then utilized. The heat sink 220 is positioned on the outer periphery of the heat spreader 210 to ensure sufficient contact between the heat sink 220 and the air outside the compressor 100, allowing the heat generated by the compressor 100 to dissipate effectively and improving heat dissipation.

[0044] It is understandable that the sintered heat pipe 230 utilizes a phase change process where the refrigerant evaporates at the hot end and then condenses at the cold end. In other words, it uses the latent heat of vaporization and condensation of the liquid to facilitate rapid heat transfer. The sintered heat pipe 230 consists of a shell, a wick, and end caps. The internal space of the sintered heat pipe 230 is under negative pressure and is filled with a low-boiling-point liquid for easy evaporation. The wick, made of a capillary porous material, is installed on the wall of the sintered heat pipe 230.

[0045] The sintered heat pipe 230 is connected to the heat spreader 210, with one part serving as the evaporation section and the other as the condensation section. When the evaporation section of the sintered heat pipe 230 is heated, the liquid in its capillary rapidly vaporizes. The vapor flows to the condensation section under the force of thermal diffusion, releasing heat in the condensation section. The liquid then flows back to the evaporation section along the porous material by capillary action, and this cycle continues until the temperatures at both ends of the sintered heat pipe 230 are equal. This cycle is rapid, allowing the sintered heat pipe 230 to quickly transfer heat from the heat spreader 210 to the heat sink 220.

[0046] In related technologies, the compressor 100 assembly 10 of this embodiment includes a heat dissipation device 200. The heat dissipation device 200 includes a heat spreader 210, a heat sink 220, and sintered heat pipes 230 connecting the heat spreader 210 and the heat sink 220. The heat spreader 210 is attached to the compressor 100. Heat from the compressor 100 can be quickly conducted to the entire heat spreader 210, providing a prerequisite for effective heat dissipation. Multiple sintered heat pipes 230 quickly conduct heat from the heat spreader 210 to the heat sink 220, allowing heat to diffuse fully outward through the heat sink, resulting in better heat dissipation of the heat dissipation device 200. This significantly improves the heat dissipation speed of the compressor 100, ensuring its continuous and stable operation.

[0047] In some embodiments, such as Figure 1 As shown, both the vapor chamber 210 and the heat sink 220 are annular, which increases the contact area between the vapor chamber 210 and the surface of the compressor 100 housing, allowing the heat generated by the compressor 100 to be more evenly conducted to the entire vapor chamber 210. The heat sink 220 is also annular, and multiple sintered heat pipes 230 are spaced apart along the circumference of the vapor chamber 210, allowing the heat on the vapor chamber 210 to be evenly conducted to the heat sink 220, and then evenly dissipated to the outside space through the heat sink 220, improving the heat dissipation effect.

[0048] Preferably, both the heat spreader 210 and the heat sink 220 are made of aluminum, which has good thermal conductivity, further improving the heat dissipation effect.

[0049] In some embodiments, such as Figure 2As shown, each sintered heat pipe 230 includes a first end 231 and a second end 232 opposite to each other.

[0050] The outer peripheral surface of the heat spreader 210 has multiple first grooves 211, each corresponding to a first end 231 of a plurality of sintered heat pipes 230. The first grooves 211 and first ends 231 are conformally matched, with at least a portion of each first end 231 embedded within its corresponding first groove 211. This embedding of the first end 231 within its corresponding first groove increases the contact area between the first end 231 of each sintered heat pipe 230 and the heat spreader 210, thereby improving the thermal conductivity between the first end 231 and the heat spreader 210.

[0051] Multiple second grooves 221 are formed on the inner circumferential surface of the heat sink 220, and each of the multiple second grooves 221 corresponds one-to-one with the second end 232 of the multiple sintered heat pipes 230. The second grooves 221 and the second end 232 are conformally matched, and at least a portion of each second end 232 is embedded in the corresponding second groove 221. Thus, by embedding the second end 232 in the corresponding second groove 221, the contact area between the second end 232 of each sintered heat pipe 230 and the heat sink 220 is increased, thereby improving the thermal conductivity between the second end 232 and the heat sink 220.

[0052] For example, the sintered heat pipe 230 is a round pipe, and the inner wall surfaces of the first groove 211 and the second groove 221 are both arc surfaces adapted to the sintered heat pipe 230.

[0053] In other embodiments, such as Figure 3 As shown, each sintered heat pipe 230 includes a first segment 233, a second segment 234, and a third segment 235 connected in sequence. The outer ends of the first segment 233 and the third segment 235 are connected to the heat sink 220. Multiple third grooves 212 are formed on the outer circumferential surface of the heat spreader 210, each corresponding to a second segment 234 of the sintered heat pipe 230. The third grooves 212 are contoured to fit the second segments 234, with each second segment 234 embedded within its corresponding third groove 212. In other words, the second segment 234 of each sintered heat pipe 230 serves as an evaporation section. After the heat from the heat spreader 210 is conducted to the second segment 234 of the sintered heat pipe 230, the second segment 234 simultaneously conducts the heat to the heat sink 220 through the first segment 233 and the third segment 235, resulting in more uniform heat distribution and improved heat dissipation efficiency.

[0054] In some embodiments, such as Figure 1As shown, the heat sink 220 includes an annular plate 222 and first heat sink fins 223. The annular plate 222 is made of a thermally conductive material, for example, aluminum. Multiple first heat sink fins 223 are spaced apart on the outer circumferential surface of the annular plate 222. This increases the contact area between the heat sink 220 and the outside air, thereby improving heat dissipation efficiency.

[0055] In other embodiments, such as Figure 4 As shown, the heat spreader 210 is annular, with one end of each sintered heat pipe 230 connected to the heat spreader 210 and the other end extending outward from the heat spreader 210. Multiple heat sinks 220 are provided, one-to-one correspondingly at the other end of each sintered heat pipe 230. In other words, heat sinks 220 are provided at the other end of the sintered heat pipe 230 to increase the heat dissipation rate of the sintered heat pipe 230 from the heat spreader 210 to the other end.

[0056] Specifically, such as Figure 4 As shown, the heat sink 220 includes a heat-conducting cylinder 224 and second heat dissipation fins 225. The heat-conducting cylinder 224 is sleeved on the other end of the corresponding sintered heat pipe 230. There are multiple second heat dissipation fins 225, which are spaced apart along the axial direction of the heat-conducting cylinder 224. This increases the contact area between the heat sink 220 and the outside air, thereby improving heat dissipation efficiency.

[0057] In some embodiments, such as Figure 1 and Figure 4 As shown, the compressor 100 assembly 10 of this embodiment further includes a gas-liquid separator 300, which is disposed on one side of the compressor 100 and close to it. The heat dissipation device 200 has an installation notch 201. When the heat dissipation device 200 is fitted onto the compressor 100, the gas-liquid separator 300 can be avoided through the installation notch 201, allowing the heat dissipation device 200 to be smoothly installed and improving the ease of installation.

[0058] Furthermore, such as Figure 5As shown, the compressor 100 assembly 10 of this embodiment further includes a mounting bracket 400 and a connector 410. A gas-liquid separator 300 is disposed on the mounting bracket 400 to conduct heat from the mounting bracket 400 to the gas-liquid separator 300. The mounting bracket 400 is fixed to the compressor 100 and / or the heat dissipation device 200 via the connector 410, allowing heat from the compressor 100 and / or the heat dissipation device 200 to be conducted to the mounting bracket 400. Thus, the mounting bracket 400 and the connector 410 conduct heat from the compressor 100 and the heat dissipation device 200 to the gas-liquid separator 300, thereby heating the gas-liquid separator 300 and enabling the refrigerant in the gas-liquid separator 300 to evaporate sufficiently.

[0059] Specifically, such as Figure 5 As shown, the connector 410 is a threaded connector (e.g., a screw or bolt assembly), and one end of the connector 410 is connected to the first heat dissipation fin 223 of the heat dissipation device 200. This allows the heat from the first heat dissipation fin 223 to be conducted sequentially to the gas-liquid separator 300 through the connector 410 and the mounting bracket 400.

[0060] The outdoor unit 20 of the air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0061] like Figure 6 As shown, the outdoor unit 20 of the air conditioner in this embodiment of the present invention includes the compressor 100 assembly 10 of any of the above embodiments.

[0062] In this embodiment of the present invention, the outdoor unit 20 of the air conditioner has a compressor 100 assembly 10 with a heat dissipation device 200 on the compressor 100. The heat from the compressor 100 can be quickly conducted to the vapor chamber 210 of the heat dissipation device 200, providing a prerequisite for effective heat dissipation. Multiple sintered heat pipes 230 quickly conduct the heat from the vapor chamber 210 to the heat sink 220, allowing the heat to diffuse fully outward through the heat sink, resulting in better heat dissipation of the heat dissipation device 200. This significantly improves the heat dissipation speed of the compressor 100, ensuring its continuous and stable operation.

[0063] In some embodiments of the present invention, the outdoor unit 20 of the air conditioner further includes a housing and a fan.

[0064] The outer casing defines an installation cavity, within which both the compressor 100 and the heat dissipation device 200 are located. The installation cavity has an air outlet and an air inlet. A fan is positioned within the installation cavity and configured to create an airflow that enters the cavity through the air inlet and exits through the air outlet. This fan facilitates the exchange of hot air within the installation cavity with outside air, ensuring that the heat dissipation device 200 dissipates heat from the installation cavity in a timely manner, thereby guaranteeing the normal operation of the compressor 100.

[0065] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
