Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat exchangers, and in particular to a heat exchanger. Background Technology
[0002] In the fields of thermal management for new energy vehicles, energy storage systems, and many industrial equipment with stringent temperature control requirements, the stable operation of critical components such as batteries highly depends on efficient and reliable thermal management systems. Battery performance, lifespan, and safety are all closely related to operating temperature; excessively high or low temperatures can lead to performance degradation, capacity decay, and even safety accidents. Therefore, precisely controlling the battery's operating temperature and ensuring it operates within a suitable temperature range is the core task of a thermal management system.
[0003] However, the current traditional design approach, which treats the battery cooler and expansion valve as separate components and connects them via piping, has a number of problems that urgently need to be solved.
[0004] From the perspective of system integration, the two independent components and the pipelines connecting them occupy a large amount of space. In application scenarios such as new energy vehicles, which have extremely high requirements for space utilization efficiency, this undoubtedly increases the difficulty of system layout, limits the installation space of other components inside the vehicle or equipment, and is not conducive to achieving miniaturization and compact design of the system. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a heat exchanger that integrates the plate heat exchanger core, EXV valve seat and EXV into one structure, eliminating the need for pipeline connections. It is simple, compact, reliable, easy to install and has low operating costs.
[0006] This utility model discloses a heat exchanger comprising a plate heat exchanger core and an EXV, with the EXV connected to the plate heat exchanger core. It also includes an mounting assembly, an aluminum tube, an EXV valve seat, and an mounting assembly. The aluminum tube is connected to the outer wall of the plate heat exchanger core and communicates with an external cooling hose. The EXV valve seat is connected to the outer wall of the plate heat exchanger core and communicates with an external air conditioning pipe. The mounting assembly is located at the bottom of the plate heat exchanger core and is used to position and install the plate heat exchanger core. High-temperature, high-pressure refrigerant enters through the EXV valve seat inlet, and after passing through the EXV, it becomes low-temperature, low-pressure refrigerant. This low-temperature, low-pressure refrigerant then circulates within the plate heat exchanger core and is finally discharged from the EXV valve seat outlet. By integrating the plate heat exchanger core, EXV valve seat, and EXV into a single structure, no piping connection is required. The structure is simple, compact, and reliable, easy to install, and has low operating costs.
[0007] Preferably, the mounting assembly includes multiple mounting plates, multiple sets of shock-absorbing inner tubes, and multiple sets of shock-absorbing pads. The top of the mounting plate is connected to the bottom of the plate heat exchanger core. The mounting plate is provided with multiple sets of mounting holes, and the multiple sets of shock-absorbing pads are respectively disposed in the multiple sets of mounting holes. The multiple sets of shock-absorbing inner tubes are respectively inserted into the multiple sets of shock-absorbing pads. By setting up the mounting plate, shock-absorbing inner tubes, and shock-absorbing pads, the convenience of mounting and positioning the plate heat exchanger core is improved.
[0008] Preferably, the aluminum tube, EXV valve seat, and mounting plate are all connected to the plate heat exchanger core by brazing; this improves the integration of the heat exchanger, reduces the use of piping, reduces space occupation, and improves processing convenience.
[0009] Preferably, it also includes a connector and screws. The connector is installed on the outer wall of the EXV, and the other end of the connector is installed on the outer wall of the EXV valve seat by screws. By setting the connector and screws, the connection between the EXV and the EXV valve seat is strengthened, and the reliability of the EXV is improved.
[0010] Compared with the prior art, the advantages of this utility model are: by integrating the plate heat exchanger core, EXV valve seat and EXV into one structure, no pipeline connection is required, the structure is simple, compact and reliable, easy to install and has low operating cost.
