Description

Technical Field

[0001] This utility model relates to the field of parking air conditioning heat dissipation technology, specifically a heat dissipation packaging device for the driver of a parking air conditioning compressor. Background Technology

[0002] In the transportation sector, parking air conditioning systems are crucial for ensuring a comfortable environment for passengers while the vehicle is stationary. Their working principle primarily involves a compressor compressing the refrigerant, circulating it within the system to achieve cooling or heating within the passenger compartment. As a core component, the compressor's normal operation relies on the effective driving and precise control of the drive unit. The drive unit generates heat during operation, and proper heat dissipation is key to ensuring stable performance and extending its service life.

[0003] Existing parking compressors are compact and easy to install and maintain. They typically house core components such as the driver circuit board within a single, molded compressor housing. Dust vents are usually placed near the circuit board for heat dissipation. However, this cooling method has significant drawbacks: firstly, its heat dissipation is poor, failing to quickly and effectively dissipate the large amount of heat generated by the driver under high load, leading to a continuous rise in driver temperature, affecting its efficiency and performance stability, and consequently impacting the operation of the entire parking air conditioning system; secondly, its cooling function is relatively simple, relying solely on natural heat dissipation through simple dust vents, which cannot meet the cooling requirements of different operating conditions. This is especially true in harsh environments such as high temperature and high humidity, where insufficient heat dissipation capacity is even more pronounced. This fails to meet the current market demand for efficient and reliable operation of parking air conditioning systems, limiting the further development and application of parking air conditioning technology.

[0004] Therefore, a heat dissipation package for the driver of a parking air conditioning compressor is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation packaging device for a driver of a parking air conditioning compressor, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation enclosure device for a driver of a parking air conditioning compressor, comprising a compressor and a driver body disposed therein. The air outlet of the compressor is connected to a cold air duct. A first heat insulation cover is fitted on the outer wall of the cold air duct. A matching first auger is connected inside the first heat insulation cover. One end of the first auger is connected to a first conveying pipe, and the other end is connected to a second conveying pipe. The other ends of the first and second conveying pipes are connected to a second heat insulation cover and are fixedly connected to the outer wall of the compressor and the driver body. An exhaust fan is connected to the air duct of both the first and second conveying pipes. A matching second auger is connected inside the second heat insulation cover. One end of the second auger is connected to the first conveying pipe, and the other end of the second auger is connected to the second conveying pipe. The exhaust fan transports the heat generated by the equipment inside the second heat insulation cover to the inside of the first heat insulation cover to exchange heat with the cold air inside the cold air duct, and then retransmits it to the inside of the second heat insulation cover to dissipate heat from the equipment, thereby achieving a circulating heat dissipation effect.

[0007] Preferably, the drive ends of both exhaust fans are connected to a drive shaft, and the other ends of both exhaust fans are connected to a driven wheel. The drive end of the compressor is connected to two driving wheels. A first transmission chain is connected to the outer walls of a corresponding set of driven wheels and driving wheels, and a second transmission chain is connected to the outer walls of a corresponding set of driven wheels and driving wheels, respectively, for driving the corresponding exhaust fans to rotate and for induced air circulation.

[0008] Preferably, the shaft walls of both drive shafts are rotatably connected to support plates, and both support plates are fixedly connected to the compressor.

[0009] Preferably, the outer and inner walls of the first auger are respectively attached to the inner wall of the first heat insulation cover and the outer wall of the cold air duct, and the outer and inner walls of the second auger are respectively attached to the inner wall of the second heat insulation cover and the outer walls of the compressor and driver body, which increases the contact time between the cold air and the equipment, improves the heat dissipation effect, and can dissipate heat for the equipment and circuit board at the same time.

[0010] Preferably, the inner walls of both the first and second heat insulation covers are connected to heat-conducting plates to improve temperature transfer efficiency.

[0011] Preferably, the left end of the first heat insulation cover is connected to a connecting seat, and the left side of the outer wall of the connecting seat is threadedly connected to a fixing seat. The fixing seat is fixedly installed on the compressor, which facilitates subsequent disassembly and maintenance of the component.

[0012] Preferably, the outer walls of the first heat insulation cover and the second heat insulation cover are respectively connected to a first heat insulation layer and a second heat insulation layer, and both the first heat insulation layer and the second heat insulation layer are made of reflective heat insulation coating.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model device uses an exhaust fan to transfer the heat generated by the equipment inside the second heat insulation cover to the inside of the first heat insulation cover for heat exchange with the cold air in the cold air duct, and then transfers it back to the inside of the second heat insulation cover to dissipate heat from the equipment, forming a circulating heat dissipation effect. Furthermore, the first and second augers are respectively attached to the heat insulation cover and the cold air duct or the outer wall of the equipment, which prolongs the contact time between the cooling air and the equipment. At the same time, it can dissipate heat from the equipment and the circuit board together, effectively improving the heat dissipation efficiency, solving the problem of poor heat dissipation effect in the prior art, and ensuring that the heat generated by the driver body under high load can be quickly dissipated, thus ensuring its working efficiency and performance stability.

[0015] 2. The device is equipped with heat-conducting plates on the inner walls of the first and second heat insulation covers, which further improves the temperature transmission efficiency. The outer walls of the covers are connected with an insulation layer made of reflective heat-insulating coating, which further prevents the loss of cold air, improves the utilization rate of cold air, and facilitates the disassembly and maintenance of subsequent components.

[0022] Example 1: Please refer to Figure 1-3 This utility model provides a technical solution: a heat dissipation packaging device for a driver of a parking air conditioning compressor, including a compressor and a driver body 1 disposed therein, belonging to the prior art. The driver body 1 is used to control the normal operation of the compressor. The air outlet of the compressor is connected to a cold air pipe 2. A first heat insulation cover 3 is sleeved on the outer wall of the cold air pipe 2. A matching first auger 4 is connected inside the first heat insulation cover 3. One end of the first auger 4 is connected to a first conveying pipe 5, and the other end is connected to a second conveying pipe 6. The other ends of the first conveying pipe 5 and the second conveying pipe 6 are connected to a second heat insulation. The second heat shield 7 is fixedly connected to the outer wall of the compressor and the drive body 1. The first conveying pipe 5 and the second conveying pipe 6 are both connected to the air supply pipes. The second heat shield 7 is connected to a matching second auger 8. One end of the second auger 8 is connected to the first conveying pipe 5 and the other end of the second auger 8 is connected to the second conveying pipe 6. The heat generated by the equipment inside the second heat shield 7 is transferred to the inside of the first heat shield 3 to exchange heat with the cold air inside the cold air pipe 2, and then transferred back to the inside of the second heat shield 7 to dissipate heat from the equipment, thereby achieving a circulating heat dissipation effect.

[0023] Both exhaust fans 13 are connected to drive shafts 14 at their drive ends, and both exhaust fans 13 are connected to driven wheels 9 at their other ends. The compressor's drive end is connected to two drive wheels 10. A first transmission chain 11 is connected to the outer walls of a set of driven wheels 9 and drive wheels 10, which rotate together. A second transmission chain 12 is connected to the outer walls of a set of driven wheels 9 and drive wheels 10, which are used to drive the corresponding exhaust fans 13 to rotate, thus circulating the exhaust air. The first transmission chain 11 and the second transmission chain 12 drive the corresponding driven wheels 9 to rotate, thereby driving the corresponding exhaust fans 13 to deliver cold air and achieve heat dissipation circulation.

[0024] In this embodiment, the shaft walls of both transmission shafts 14 are rotatably connected to support plates 15, and both support plates 15 are fixedly connected to the compressor to ensure the stability of the transmission of the transmission shafts 14.

[0025] In this embodiment, the outer and inner walls of the first auger 4 are respectively attached to the inner wall of the first heat insulation cover 3 and the outer wall of the cold air duct 2. The outer and inner walls of the second auger 8 are respectively attached to the inner wall of the second heat insulation cover 7 and the outer wall of the compressor and driver body 1. This increases the contact time between the cooling air and the equipment, improves the heat dissipation effect, and can also dissipate heat for the equipment and circuit board. The inner walls of the first heat insulation cover 3 and the second heat insulation cover 7 are both connected to heat-conducting plates to improve temperature transfer efficiency.

[0026] In this embodiment, a connecting seat 17 is connected to the left end of the first heat insulation cover 3, and a fixing seat 16 is threadedly connected to the left side of the outer wall of the connecting seat 17. The fixing seat 16 is fixedly installed on the compressor, which facilitates the subsequent disassembly and maintenance of the components.

[0027] The outer walls of the first heat insulation cover 3 and the second heat insulation cover 7 are respectively connected to the first heat insulation layer 18 and the second heat insulation layer 19. The first heat insulation layer 18 and the second heat insulation layer 19 are both made of reflective heat insulation coating to further prevent the loss of cold air, improve the utilization rate of cold air, and realize the simultaneous heat dissipation of the compressor and its internal drive equipment.

[0028] The working principle is as follows: This scheme uses the exhaust fan 13 to transfer the heat generated inside the equipment of the second heat insulation cover 7 to the inside of the first heat insulation cover 3 for heat exchange with the cold air inside the cold air duct 2. Specifically, the cold air enters the cold air duct 2 from the air outlet of the compressor and cooperates with the first auger 4 inside the first heat insulation cover 3 to form a cold air circulation path. The outer wall of the first auger 4 is in contact with the inner wall of the first heat insulation cover 3, and the inner wall is in contact with the outer wall of the cold air duct 2, ensuring that the cold air flows fully inside the first heat insulation cover to achieve preliminary heat exchange. After heat exchange, the cold air is transported by the exhaust fan 13 to the inside of the second heat insulation cover 7 through the first conveying pipe 5 and the second conveying pipe 6. Inside the second heat insulation cover, the outer wall of the second auger 8 is in contact with the inner wall of the second heat insulation cover, and the inner wall is in contact with the outer wall of the compressor and the drive body 1, so that the cold air can be in contact with the drive body 1. The main body of the device and its circuit board are in full contact, carrying away heat and achieving heat dissipation. Through the continuous operation of the exhaust fan 13, cold air is circulated between the first heat insulation cover 3, the cold air duct 2, and the second heat insulation cover 7, thereby achieving a highly efficient heat dissipation effect. At the same time, heat-conducting plates are provided on the inner walls of the first heat insulation cover 3 and the second heat insulation cover 7 to further improve the temperature transmission efficiency. The outer walls are connected to the insulation layers 18 and 19 made of reflective heat insulation coating to prevent the loss of cold air and improve the utilization rate of cold air. In addition, through the cooperation of the transmission chains 11 and 12 and the driven wheel 9 and the driving wheel 10, the exhaust fan 13 is driven by the power of the compressor to achieve heat dissipation circulation without the need for additional energy input, thus reducing energy consumption. The entire device has a compact structure and high heat dissipation efficiency, effectively solving the problems of poor heat dissipation and single function in the prior art.
