Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle thermal management systems, and in particular relates to an integrated structure of a high-efficiency thermal management system. Background Art

[0002] With the popularity of electric and hybrid vehicles, the thermal management system of the whole vehicle is developing in the direction of integration. The current integration scheme of the refrigerant circuit is mainly to integrate the relevant plate heat exchangers, valves, some flow channels, mounting brackets, etc. in the refrigerant side circuit. These integration schemes still exclude the compressor and connect the pipeline to the compressor, resulting in loose spatial distribution of the entire system, large space occupation, poor lightweight performance, and cumbersome vehicle assembly process.

[0003] In summary, the specific purposes of this application are: 1. Highly integrated, greatly reducing the space occupied by the system; 2. Reduce additional pipe connections, significantly reducing costs and weight; 3. Improve vehicle production efficiency; 4. The compact design effectively reduces the system volume, thereby reducing the amount of refrigerant charged.

[0004] To this end, the present invention proposes an efficient thermal management system integrated structure. Summary of the invention

[0005] The purpose of the present invention is to propose an integrated structure of an efficient thermal management system in order to solve the problem that the existing integrated solution still excludes the compressor and connects the pipeline to the compressor, resulting in loose spatial distribution of the entire system, large space occupation, poor lightweight performance, and complicated vehicle assembly process.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: an integrated structure of a high-efficiency thermal management system, comprising a compressor housing, on which a first plate heat exchanger and a second plate heat exchanger, as well as a liquid storage dryer and / or a gas-liquid separator are sleeved; The centers of mass of the first plate heat exchanger and the second plate heat exchanger are located within the physical envelope of the compressor housing; A refrigerant exhaust port and a refrigerant air intake port are arranged on the compressor housing, a first refrigerant inlet, a first refrigerant outlet, a first water inlet and a first water outlet are arranged on the first plate heat exchanger, a second refrigerant inlet, a second refrigerant outlet, a second water inlet and a second water outlet are arranged on the second plate heat exchanger, a third refrigerant inlet and a third refrigerant outlet are arranged on the liquid storage dryer, and the refrigerant exhaust port, the first refrigerant inlet, the first refrigerant outlet, the third refrigerant inlet, the third refrigerant outlet, the second refrigerant inlet, the second refrigerant outlet and the refrigerant air intake port are connected in sequence.

[0007] As a further description of the above technical solution: The first plate heat exchanger and the second plate heat exchanger are formed by stacking multiple layers of plates along the axial direction of the compressor housing.

[0008] As a further description of the above technical solution: The projection profile of the plate along the axial direction of the compressor housing is annular.

[0009] As a further description of the above technical solution: The first plate heat exchanger and the second plate heat exchanger are connected to the compressor housing in a detachable manner or by welding.

[0010] As a further description of the above technical solution: A first sensor mounting hole is also provided on the compressor housing, in which a first sensor is installed; a throttle valve mounting interface and a second sensor mounting hole are provided on the liquid storage dryer, a throttle valve is installed on the throttle valve mounting interface, and a second sensor is installed on the second sensor mounting hole.

[0011] As a further description of the above technical solution: The first sensor and the second sensor are temperature sensors, pressure sensors or refrigerant leakage sensors.

[0012] As a further description of the above technical solution: The liquid storage dryer and / or the gas-liquid separator are welded into one body with the first plate heat exchanger and the second plate heat exchanger, and then assembled to the compressor housing in a detachable form.

[0013] As a further description of the above technical solution: The liquid storage dryer and / or the gas-liquid separator are detachably connected to the first plate heat exchanger and the second plate heat exchanger, and then assembled to the compressor housing in a detachable form.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Compared with the traditional scheme of separating the compressor and the integrated module, the present invention integrates the plate heat exchanger with the compressor, thereby reducing the number of parts and components and the assembly workload; thus reducing the cost of the whole machine; 2. In the present invention, since all refrigerant circuit components are directly mounted on the compressor housing, the refrigerant circuit and the compressor housing are integrated, which greatly reduces the internal volume of the relevant refrigerant circuit system, thereby reducing the refrigerant charge amount of the system; 3. In the present invention, since all refrigerant circuit components are directly installed on the compressor housing, the refrigerant circuit is integrated with the compressor cylinder body, and related valves and sensors are installed on the compressor housing, the space occupation of the entire refrigerant circuit system is greatly reduced and the system weight is significantly reduced.
