[0002] With the booming development of the new energy vehicle market, thermal management technology has increasingly become a focus for automakers. Fully integrated thermal management solutions have become standard equipment for electric vehicles. By efficiently integrating multiple valves on the coolant and refrigerant sides, it achieves modular and integrated management and utilization of the vehicle's thermal energy, thereby effectively improving energy efficiency.

[0003] Existing plate heat exchangers typically consist of multiple sets of parallel heat exchange plates, with adjacent heat exchange plates separated by a sealed structure to form independent flow channels. One set of flow channels is for the high-temperature refrigerant to flow, and the other set is for the coolant to flow. Heat is transferred between the two through the metal walls of the heat exchange plates. However, this traditional structure has significant drawbacks: the refrigerant and coolant flow in separate, closed flow channels, and heat exchange only occurs through a single metal plate wall. The heat transfer path is singular and the contact area is limited, resulting in low heat exchange efficiency, which makes it difficult to meet the requirement of rapid cooling of the high-temperature refrigerant discharged from the compressor cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-8 This utility model provides an integrated device for compressor cylinder and heat exchanger, including compressor cylinder 1 and heat exchanger assembly 2, wherein; The heat exchanger assembly 2 is connected to the compressor cylinder 1 through the refrigerant inlet 4. The upper surface of the heat exchanger assembly 2 is provided with a refrigerant outlet 3, a coolant inlet 5 and a coolant outlet 6. The refrigerant inlet 4 and the refrigerant outlet 3 form a refrigerant channel, and the coolant inlet 5 and the coolant outlet 6 form a coolant channel. The refrigerant channel and the coolant channel are arranged in a cross pattern.

[0022] The high-temperature refrigerant discharged from the compressor cylinder 1 enters the heat exchanger assembly 2 through the refrigerant inlet 4. At the same time, the coolant enters the heat exchanger assembly 2 through the coolant inlet 5. The high-temperature refrigerant and the coolant form cross heat exchange in the heat exchanger assembly 2. After the heat exchange is completed, the cooled refrigerant is discharged from refrigerant outlet 3, and the cooled liquid after absorbing heat is discharged from cooled liquid outlet 6.

[0023] Specifically, the heat exchanger assembly 2 includes a heat exchanger housing 21, and a sealed total heat exchange chamber 22 is formed inside the heat exchanger housing 21.

[0024] Specifically, several sets of heat exchange plates 23 and 24 are installed in the main heat exchange cavity 22. The heat exchange plates 23 and 24 are arranged alternately in sequence.

[0025] The high-temperature refrigerant discharged from the compressor cylinder 1 enters the heat exchanger assembly 2 through the refrigerant inlet 4. The first heat exchange plate 23 is directly separated from the heat exchanger shell 21. After passing through the heat exchange plate 23 and the second heat exchange plate 24, it enters the cooling chamber 26 between the second heat exchange plate 24 and the next adjacent heat exchange plate 23. At the same time, the coolant enters the heat exchanger assembly 2 through the coolant inlet 5, passes through the heat exchange plate 23, and enters the cooling chamber 25 between the first heat exchange plate 23 and the second heat exchange plate 24, achieving a cross-heat exchange effect. The above steps are repeated in sequence. Finally, the coolant that has absorbed heat is discharged from the coolant outlet 6. The high-temperature refrigerant and the coolant form a cross-heat exchange in the heat exchanger assembly 2.

[0026] Specifically, the heat exchanger housing 21 is arranged in a semi-cylindrical shape.

[0027] Specifically, both the heat exchange plate 23 and the heat exchange plate 24 are plate-shaped structures, and adjacent heat exchange plates 23 and 24 overlap and are installed sequentially.

[0028] Specifically, the opposite sides of the heat exchange plates 23 are provided with extension edge 27 and extension edge 28, respectively, and the opposite sides of the heat exchange plates 24 are provided with extension edge 39 and extension edge 40, respectively.

[0029] By using Yanbian 1 27 and Yanbian 2 28 to block the coolant from entering the refrigeration chamber 26, and by using Yanbian 3 29 and Yanbian 4 30 to block the refrigerant from entering the refrigeration chamber 25, a layered blocking effect is achieved.

[0030] Specifically, the first edge 27 is provided with a liquid exchange hole 233 that penetrates the first heat exchange plate 23, the second edge 28 is provided with a liquid exchange hole 234 that penetrates the first heat exchange plate 23, the third edge 29 is provided with a liquid exchange hole 243 that penetrates the second heat exchange plate 24, and the fourth edge 30 is provided with a liquid exchange hole 244 that penetrates the second heat exchange plate 24.

[0031] Specifically, the heat exchange plate 23 is provided with a first flow hole 231 and a second flow hole 232, and the heat exchange plate 24 is provided with a third flow hole 241 and a fourth flow hole 242.

[0032] Specifically, the adjacent extension 1 27 corresponds one-to-one with the adjacent flow hole 3 241, the adjacent extension 2 28 corresponds one-to-one with the adjacent flow hole 4 242, the extension 3 29 corresponds one-to-one with the next group of flow holes 1 231, and the extension 4 30 corresponds one-to-one with the next group of flow holes 232.

[0033] Specifically, the adjacent extension 1 27 corresponds one-to-one with the adjacent flow hole 3 241, the adjacent extension 2 28 corresponds one-to-one with the adjacent flow hole 4 242, the extension 3 29 corresponds one-to-one with the next group of flow holes 1 231, and the extension 4 30 corresponds one-to-one with the next group of flow holes 232.

[0034] Specifically, the first edge 27 and the second edge 28 abut against the adjacent second heat exchange plate 24, and the second edge 28 and the third edge 29 abut against the next set of first heat exchange plates 23.

[0035] Working principle of this utility model: In use, there are two flow path modes: refrigerant and coolant, as detailed below: Refrigerant: The high-temperature refrigerant discharged from the compressor cylinder 1 enters the heat exchanger assembly 2 through the refrigerant inlet 4. It first fills the gap between the first heat exchange plate 23 and the heat exchanger shell 21, and then flows through the flow holes 231 and 232 of the heat exchange plate 23. Since the extension edge 39 corresponds to the next set of flow holes 231 and the extension edge 40 corresponds to the next set of flow holes 232, it directly enters the cooling chamber 26 between the heat exchange plate 24 and the next adjacent heat exchange plate 23 through the liquid exchange holes 234 and 244. The above steps are repeated in sequence, and finally, the cooled refrigerant is discharged from the refrigerant outlet 3.

[0036] Coolant: The coolant enters the heat exchanger assembly 2 through the coolant inlet 5, and then enters the cooling chamber 25 between the heat exchange plate 23 and the heat exchange plate 24 through the first heat exchange plate 27 and the second heat exchange plate 28. The first heat exchange plate 24 has a flow hole 241 and a flow hole 242. The above steps are repeated in sequence. Finally, the coolant that has absorbed heat is discharged from the coolant outlet 6.

[0037] Based on the above specific usage process, the coolant is blocked from entering the refrigeration chamber 26 by means of Yanbian 1 27 and Yanbian 2 28, and the refrigerant is blocked from entering the refrigeration chamber 25 by means of Yanbian 3 29 and Yanbian 4 30, thereby achieving the effect of layered blocking.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
