Description

Technical Field

[0001] This utility model relates to an overheat-proof cylinder head for a refrigerator compressor. Background Technology

[0002] The cylinder head of a refrigerator compressor is one of the key components of the compressor. Its main function is to seal the cylinder, forming a working space that allows the compressor to use valve components to achieve refrigerant intake, compression, and discharge. Existing refrigerator compressor cylinder heads are usually equipped with heat dissipation fins to enhance heat dissipation. However, the heat dissipation capacity of the heat dissipation fins is limited. When the refrigerator compressor operates at high power for a long time, heat may not be able to dissipate sufficiently from the heat dissipation fins, leading to overheating of the refrigerator compressor and affecting normal operation. Therefore, it is necessary to develop an overheat-proof cylinder head for refrigerator compressors to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an overheat-resistant cylinder head for a refrigerator compressor to solve the problems mentioned in the background art.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An overheat-resistant cylinder head for a refrigerator compressor includes an end cover. Each of the four sides of the end cover is provided with heat dissipation fins and heat-conducting plates. Multiple heat dissipation fins are evenly spaced on the sides of the end cover. A top plate is provided on the upper side of the end cover, and multiple support rods connect the top plate to the end cover. A fan is provided on the top plate, and a flow guide platform is provided below the fan. The flow guide platform is fixed to the top of the end cover and is frustum-shaped. Multiple flow guide grooves are radially arranged on the sides of the flow guide platform.

[0006] Preferably, the heat-conducting plate is provided with a rectangular groove, and a temperature sensor is provided in the rectangular groove.

[0007] Preferably, each of the heat dissipation fins has a groove on one side, and the heat-conducting plate passes through the groove and fits against the side of the end cover.

[0008] Preferably, a connecting plate is provided between the heat-conducting plates on two adjacent sides of the end cover. The connecting plate has an L-shaped structure and is connected to the heat-conducting plate by bolts.

[0009] Preferably, the bottom of the side of the end cap is provided with a mounting frame, and mounting holes are provided at the four corners of the mounting frame.

[0010] The beneficial effects of this utility model are: This utility model can use the temperature sensor on the heat conduction plate to monitor the temperature of the cylinder head of the refrigerator compressor. When the refrigerator compressor is in a high-power working state for a long time, the temperature sensor will detect that the cylinder head temperature is too high and control the fan to generate airflow. The airflow blows onto the guide platform and then quickly spreads to the surroundings along the guide groove on the guide platform, so that the airflow quickly flows through the gaps between each heat dissipation fin, thereby accelerating the heat dissipation effect of the heat dissipation fins and preventing the refrigerator compressor from overheating because the heat cannot be fully dissipated from the heat dissipation fins.

[0020] See Figures 1 to 7The refrigerator compressor overheat protection cylinder head shown includes an end cover 11. Each of the four sides of the end cover 11 is provided with heat dissipation fins 13 and heat-conducting plates 14. Multiple heat dissipation fins 13 are evenly spaced on the sides of the end cover 11. A top plate 16 is provided on the upper side of the end cover 11. Multiple support rods 19 connect the top plate 16 to the end cover 11. A fan 17 is provided on the top plate 16. A flow guide platform 18 is provided below the fan 17 and is fixed to the top of the end cover 11. The flow guide platform 18 is frustum-shaped, and multiple radial flow guide grooves 22 are provided on its sides.

[0021] Furthermore, a rectangular groove 20 is provided on the heat-conducting plate 14, and a temperature sensor 21 is provided in the rectangular groove 20.

[0022] Furthermore, each of the heat dissipation fins 13 has a groove 23 on one side, and the heat conduction plate 14 passes through the groove 23. The heat conduction plate 14 is in contact with the side of the end cover 11. The heat conduction plate 14 is in close contact with the side of the end cover 11, and the heat on the end cover 11 is transferred to the heat conduction plate 14 so that the temperature sensor 21 on the heat conduction plate 14 can monitor the temperature of the cylinder head. The heat conduction plate 14 is close to the heat dissipation fins 13, and the heat transferred from the end cover 11 to the heat conduction plate 14 can be transferred to the heat dissipation fins 13 for heat dissipation.

[0023] Furthermore, a connecting plate 15 is provided between the heat-conducting plates 14 on two adjacent sides of the end cover 11. The connecting plate 15 has an L-shaped structure and is connected to the heat-conducting plates 14 by bolts. The four heat-conducting plates 14 are connected by the connecting plates 15 to form a frame structure and are clamped to the side of the end cover 11, so that the four heat-conducting plates 14 can be tightly attached to the four sides of the end cover 11 respectively.

[0024] Furthermore, the bottom of the side of the end cover 11 is provided with a mounting frame 12, and mounting holes 24 are provided at the four corners of the mounting frame 12; align the mounting holes 24 on the mounting frame 12 with the corresponding threaded holes on the refrigerator compressor, and then use bolts to install the cylinder head on the compressor.

[0025] The working principle of this utility model is as follows: When the refrigerator compressor is working, the heat generated during the operation is transferred to the end cover 11, and the heat on the end cover 11 is then transferred to the heat conduction plate 14. The temperature sensor 21 on the heat conduction plate 14 detects the heat and can monitor the temperature of the cylinder head. The heat on the heat conduction plate 14 is then transferred to each heat dissipation fin 13. The multiple heat dissipation fins 13 have a large heat dissipation area, so that the heat transferred to the heat dissipation fins 13 is quickly dissipated. When the refrigerator compressor is in a high-power working state for a long time, the temperature sensor 21 will detect that the cylinder head temperature is too high. At this time, the temperature sensor 21 controls the fan 17 to start. The fan of the fan 17 rotates to generate airflow. The airflow blows onto the guide platform 18, and then quickly spreads to the surroundings along the guide groove 22 on the guide platform 18, so that the airflow quickly flows through the gaps between each heat dissipation fin 13, thereby accelerating the heat dissipation effect of the heat dissipation fins 13 and preventing the refrigerator compressor from overheating due to insufficient heat dissipation from the heat dissipation fins 13.

[0026] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
