Technical Field

[0001] The present invention belongs to the technical field of vehicle thermal management systems, and in particular relates to a novel compressor integrated structure. Background Art

[0002] With the development of electric and hybrid vehicles, the thermal management system of the whole vehicle has been moving towards integration. The current integrated module mainly integrates the channels and related parts of the refrigerant and water channels directly using connecting pipes, but it occupies a large volume and is costly.

[0003] Existing integrated modules usually consist of a compressor, an evaporator (chiller), a water-cooled condenser, an air conditioning exhaust pipe, an air conditioning intake pipe, an air conditioning liquid pipe, a drying bottle and a compressor bracket. Usually, there are many fixing points on the compressor bracket. After the compressor is fixed on one side of the bracket, the heat absorption heat exchanger, the heat dissipation heat exchanger and the drying bottle are installed on the other side through the bracket. After the overall installation is completed, the various components are connected together using pipes. The disadvantages of this integration method are that it occupies a large volume, is complex to install, and is costly. In addition, due to the large installation volume, the module requires a large amount of refrigerant.

[0004] To this end, the present invention proposes a novel compressor integrated structure. Summary of the invention

[0005] The purpose of the present invention is to propose a new compressor integrated structure in order to solve the problems that the existing compressor integrated structure occupies a large volume, is complex to install, has a high cost, and requires a large amount of refrigerant to be added to the module due to the large installation volume.

[0006] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a new type of compressor integrated structure, including a compressor, the compressor having a compressor suction chamber, a compressor exhaust chamber and a compressor cylinder body, and also including a chiller and / or a water-cooled condenser, the compressor suction chamber is connected to the chiller, and the compressor exhaust chamber is connected to the water-cooled condenser.

[0007] As a further description of the above technical solution: the chiller and the water-cooled condenser are arranged on both sides of the compressor and are welded or detachably sealed to the compressor.

[0008] As a further description of the above technical solution: a top cover is also fixed on the top of the compressor, and a controller is fixed on the top of the top cover.

[0009] As a further description of the above technical solution: a refrigerant interface is provided on the top of the top cover.

[0010] As a further description of the above technical solution: an expansion valve is arranged on the top of the top cover, which is used to throttle and reduce the pressure of the refrigerant, so that the refrigerant is converted from a high-temperature and high-pressure liquid to a low-temperature and low-pressure liquid.

[0011] As a further description of the above technical solution: a temperature sensor is arranged on the top of the top cover to detect the temperature of the air-conditioning system and provide temperature data to the control system to achieve precise adjustment of the cooling effect.

[0012] As a further description of the above technical solution: a pressure sensor is arranged on the top of the top cover to measure the pressure of the refrigerant in the air-conditioning pipeline to ensure that the refrigerant operates within a safe pressure range.

[0013] As a further description of the above technical solution: a refrigerant leakage sensor is provided on the compressor to monitor in real time whether there is refrigerant leakage, and once a leakage is detected, an alarm signal is issued in time.

[0014] As a further description of the above technical solution: a refrigerant circuit is arranged on the compressor cylinder.

[0015] As a further description of the above technical solution: at least four shock-absorbing pads are installed at the bottom of the compressor.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The water-cooled condenser, chiller and compressor are integrated, and the liquid storage, refrigerant channel, various valves and sensors are integrated with the compressor, which reduces the number of parts and the assembly workload, thereby reducing the cost of the whole machine; 2. Since all refrigerant circuit components are directly installed on the compressor cylinder, the refrigerant circuit and the compressor cylinder are integrated, which greatly reduces the volume of the relevant refrigerant circuit system, thereby reducing the system refrigerant charge; 3. In the present invention, since the heat exchanger is directly connected to the compressor, the flow resistance of the pipeline is eliminated, the refrigerant leakage is reduced, the performance is improved and the energy consumption is reduced.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-2 The present invention provides a technical solution: a new type of compressor integrated structure, including a compressor, the compressor has a compressor suction chamber 2, a compressor exhaust chamber 3 and a compressor cylinder, and also includes a chiller 1 and / or a water-cooled condenser 4, which can be connected separately or together, the compressor suction chamber 2 is connected to the chiller 1, and the compressor exhaust chamber 3 is connected to the water-cooled condenser 4. It is worth noting that the compressor is designed with a flow channel connected to the heat exchanger (chiller 1 and water-cooled condenser 4), a liquid storage tank is installed, and a liquid storage function is realized. This function can also be connected by connecting an external pipeline between the heat exchangers to realize the connection, liquid storage and installation of the liquid storage tank.

[0022] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, chiller 1 and the water-cooled condenser 4 are arranged around the compressor and are welded or detachably sealed to the compressor; specifically, the exhaust hole of chiller 1 is connected to the intake hole of the compressor intake chamber 2 by welding or detachably sealed; the air inlet hole of the water-cooled condenser 4 is connected to the exhaust hole of the compressor exhaust chamber 3 by welding or detachably sealed.

[0023] As a further description of the above technical solution: a top cover 5 is also fixed on the top of the compressor, and a controller 6 is fixed on the top of the top cover 5.

[0024] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, a refrigerant interface is provided on the top of the top cover 5 for realizing other extended functions.

[0025] In a specific embodiment of the present invention, Figure 1 and Figure 2As shown, an expansion valve 8 is provided on the top of the top cover 5, which is used to throttle and reduce the pressure of the refrigerant, so that the refrigerant is converted from a high-temperature and high-pressure liquid to a low-temperature and low-pressure liquid, creating conditions for heat absorption and refrigeration in the evaporator. The expansion valve 8 adopts a thermal expansion valve or an electronic expansion valve. The thermal expansion valve relies on a temperature sensing package to sense temperature changes and adjusts the valve opening by internal pressure. The electronic expansion valve collects parameters such as temperature and pressure through sensors, and the valve opening is accurately controlled by the control system. The specific connection is: usually one end is connected to the pipeline at the outlet of the water-cooled condenser 4, and the other end is connected to the pipeline at the inlet of chiller 1.

[0026] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, a temperature sensor 7 is provided on the top of the top cover 5 to detect the temperature of the air conditioning system and provide temperature data to the control system to achieve accurate adjustment of the cooling effect. The temperature sensor 7 is generally installed at important pressure monitoring points such as the compressor inlet and outlet, the condenser inlet and outlet, etc., by using components such as thermistors and thermocouples, whose resistance value or potential difference changes with temperature.

[0027] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, a pressure sensor 9 is provided on the top of the top cover 5, which is used to measure the pressure of the refrigerant in the air conditioning pipeline to ensure that the refrigerant operates within a safe pressure range. The pressure acts on the elastic element inside the sensor to deform it, and the pressure change is converted into an electrical signal output through a corresponding conversion mechanism. It is generally installed at important pressure monitoring points such as the compressor inlet and outlet, and the condenser inlet and outlet.

[0028] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the compressor is equipped with a refrigerant leakage sensor for real-time monitoring of refrigerant leakage. Once a leak is detected, an alarm signal is issued in a timely manner. The sensor works based on the detection of refrigerant molecules, the perception of pressure changes, or other physical or chemical properties related to refrigerant leakage. It is usually installed in locations prone to refrigerant leakage, such as pipeline interfaces, near valves, etc.

[0029] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, a refrigerant circuit is provided on the compressor cylinder.

[0030] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, at least two shock-absorbing pads 10 are installed at the bottom of the compressor to reduce vibration of the compressor and effectively reduce noise.

[0031] It is also worth mentioning that the compressor is equipped with a stop valve, which is mainly used to cut off or connect the flow of refrigerant in the air conditioning pipeline, and plays an important role in the installation, repair and maintenance of the system. It is generally installed at the branch of the pipeline, the position that needs to be cut off, or the key control node.

[0032] Working principle: Since the water-cooled condenser 4 and chiller 1 are integrated with the compressor, the liquid storage, refrigerant channel, various valves and sensors are integrated with the compressor, the number of parts and components is reduced, and the assembly workload is reduced, thereby reducing the cost of the whole machine; Since all refrigerant circuit components are directly installed on the compressor cylinder, the refrigerant circuit and the compressor cylinder are integrated, which greatly reduces the volume of the relevant refrigerant circuit system, thereby reducing the system refrigerant charge; In the present invention, since the heat exchanger is directly connected to the compressor, the flow resistance of the pipeline is eliminated, the refrigerant leakage is reduced, the performance is improved and the energy consumption is reduced.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
