[0022] Shell 1, cylinder 11, upper end cover 12, lower end cover 13, mounting plate 2, valve body 3, sensor 4, heat exchanger 5, regenerator 6, gas-liquid separator 7. Detailed Implementation

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figure 1 and Figure 2 As shown, the vehicle refrigeration system integrated device of this invention includes a housing 1, a regenerator 6, a gas-liquid separator 7, a heat exchanger 5, a valve body 3, and a sensor 4. The housing 1 includes a cylindrical body 11 and a mounting plate 2. The cylindrical body 11 has a cavity and an interface communicating with the cavity. The mounting plate 2 is connected to the outer circumferential surface of the cylindrical body 11. The regenerator 6 and the gas-liquid separator 7 are disposed in the cavity. The heat exchanger 5 is connected to the mounting plate 2. The valve body 3 and the sensor 4 are connected to the housing 1.

[0025] It should be noted that the vehicle's refrigeration system includes many components such as the regenerator 6, gas-liquid separator 7, heat exchanger 5, and condenser. These components are connected by refrigerant pipes, which are equipped with valves 3 to control the direction and flow of the refrigerant and sensors 4 to detect the temperature or pressure of the refrigerant. In this related technology, each component is arranged as a separate component in the front compartment of the vehicle and connected to each other through pipes and into the system circuit. Since each component exists independently, special brackets need to be designed for assembly, resulting in a large system layout space occupation, increased overall cost and weight, and complex assembly.

[0026] The vehicle refrigeration system integration device of this invention has a cavity inside the cylinder 11, which can accommodate the regenerator 6 and the gas-liquid separator 7. The heat exchanger 5, valve body 3 and sensor 4 are all located on the housing 1, so that the regenerator 6, gas-liquid separator 7, heat exchanger 5, valve body 3 and sensor 4 can be integrated on the housing 1, the components are arranged in a centralized manner, reducing space occupation, and each component can be connected to the vehicle body through the housing 1 without the need for a large number of brackets, thus reducing the number of components.

[0027] Furthermore, the housing 1 has a valve body mounting section and a sensor mounting section. The valve body mounting section can mount the valve body 3, and the sensor mounting section can mount the sensor 4. Thus, the sensor 4 and the valve body 3 are integrated on the housing 1, effectively avoiding the problem of the valve body 3 occupying space when arranged separately in the front compartment.

[0028] Furthermore, such as Figure 1 and Figure 2As shown, the housing 1 also includes an upper end cover 12 and a lower end cover 13. The top of the cylinder 11 has an upper interface and the bottom of the cylinder 11 has a lower interface. The upper end cover 12 is connected to the top of the cylinder 11 and is sealed to the upper interface. The lower end cover 13 is connected to the bottom of the cylinder 11 and is sealed to the lower interface. The upper end cover 12 and the lower end cover 13 are provided with valve body mounting parts and sensor mounting parts.

[0029] Optionally, the valve body mounting portion and the sensor mounting portion are arranged at intervals, and there are multiple valve body mounting portions arranged at intervals, and / or there are multiple sensor mounting portions arranged at intervals.

[0030] Understandably, the integration of multiple sensors 4 and multiple valve bodies 3 at the upper end cover 12 and lower end cover 13 reduces the length of pipe connections, lowers pressure loss and refrigerant leakage risk, and helps improve the overall performance of the system. Furthermore, the separation of the installation parts can avoid assembly interference between the valve body 3 and the sensor 4.

[0031] Furthermore, the upper end cover 12 and the side facing the mounting plate 2 have a first through hole, which communicates with the cavity through an upper interface. The lower end cover 13 has a second through hole on the side facing the mounting plate 2, which communicates with the cavity through a lower interface. It can be understood that the first and second through holes can realize the pipe connection and layout between the regenerator 6 and the heat exchanger 5.

[0032] Preferably, the regenerator 6 is located inside the liquid separator.

[0033] The vehicle in this embodiment of the invention includes a refrigeration system integration device, which is the vehicle refrigeration system integration device described above, and the refrigeration system integration device is installed in the front compartment of the vehicle.

[0034] The vehicle of this invention, by adopting the above-mentioned integrated refrigeration system device, can centrally arrange components, reduce space occupation, and optimize the overall vehicle layout.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the vehicle includes an evaporator, a built-in condenser, and a compressor. The evaporator is connected between a gas-liquid separator 7 and a regenerator 6. The regenerator 6, compressor, built-in condenser, and heat exchanger 5 are connected in sequence, and the heat exchanger is connected to the regenerator to form a refrigeration cycle. In other words, the regenerator 6, gas-liquid separator 7, and heat exchanger 5 integrated on the housing 1 can be connected to other components of the refrigeration system as needed.

[0036] It should be noted that during air conditioning cooling, the gas-liquid separator 7 separates the refrigerant liquid and gas to ensure that the outlet is refrigerant gas. The regenerator 6 further cools the refrigerant entering the evaporator and increases the superheat of the refrigerant entering the compressor to prevent liquid slugging.
