Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an integrated core heat exchanger. Background Art

[0002] In existing heat exchanger technology, heat dissipation efficiency and compact volume design are key considerations. Traditional heat exchanger design often focuses on a single performance indicator, such as heat dissipation efficiency or volume, while ignoring the balance between the two. With the development of technology, especially in the fields of automobiles and electronic equipment, there is an increasing demand for integrated core heat exchangers. These heat exchangers must not only have efficient heat dissipation performance, but also have a compact structural design to facilitate manufacturing convenience and system integration flexibility.

[0003] In the prior art with patent publication number CN219302976U, a double-layer water-cooled radiator is disclosed, which includes a liquid inlet nozzle, a liquid outlet nozzle, a first heat dissipation layer, a second heat dissipation layer, a first water tank and a second water tank. The first heat dissipation layer is located above the second heat dissipation layer, and the water tank is divided into different chambers by an internal partition, realizing a U-shaped loop design. Although this design has achieved compact volume and improved heat dissipation performance to a certain extent, it still has some limitations. For example, the radiator in the comparative document is designed as an integral water tank, which is not convenient for integrating more heat dissipation cores, limiting its adaptability in a wider range of application scenarios. The integral water tank design means that the water tank and the heat dissipation core are manufactured and installed as a single unit. This design is not conducive to adding additional heat dissipation cores to the existing radiator system. Therefore, the present application proposes an integrated core heat exchanger to solve the problem that the integral water tank design limits the number of integrated heat dissipation cores, which is not conducive to expansion and modular design.

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1 The integrated core heat exchanger includes at least two layers of heat dissipation cores 100 and a chamber assembly 200 . A main board 300 is fixed to the end of the heat dissipation core 100 , and the side of the main board 300 away from the heat dissipation core 100 is connected to the chamber assembly 200 .

[0021] By fixing the main board 300 at the end of the heat dissipation core 100 and connecting the main board 300 to the chamber assembly 200, the present design realizes the modularization of the heat exchanger. This modular design allows the individual heat dissipation cores 100 to be replaced or upgraded as needed without replacing the heat exchanger as a whole, thereby improving the flexibility of the system and the convenience of maintenance. If more heat dissipation capacity is required, the integrated core heat exchanger can be expanded by adding additional core layers or single-layer core size. This design allows the size and performance of the heat exchanger to be flexibly adjusted according to the needs of the heat load.

[0022] In some embodiments, the main board 300 has outwardly turned edges 310 on the upper and lower sides, and the adjacent edges 310 of adjacent main boards 300 are overlapped and fixed to each other; the edges 310 are wrapped around the edge of the chamber assembly 200 .

[0023] The design of the retaining edge 310 enhances the connection stability between the main board 300 and the chamber assembly 200. The outwardly turned retaining edge 310 can provide a larger contact area and better fixation, thereby ensuring a tight fit between the main board and the chamber assembly and reducing displacement caused by vibration or thermal expansion. The mutually overlapped and fixed retaining edges 310 simplify the assembly process of the main board 300 and the chamber assembly 200. This design allows for quick and accurate assembly of the various components, improving production efficiency.

[0024] By overlapping the flanges 310 of the main boards 110 at the ends of the multi-layer integrated core 100 and putting the whole into a brazing furnace for brazing, the design realizes the modularization of the heat exchanger core. This modular design allows the integrated core to be combined or upgraded as needed without increasing the investment in special molds for customized development, thereby improving the convenience of product manufacturing and the flexibility of system integration.

[0025] In some embodiments, the chamber assembly 200 includes a water outlet chamber 210, a water inlet chamber 220, and a reversing chamber 230; the water outlet chamber 210 is disposed between adjacent ribs 310 of the starting mainboard 300 of the first heat dissipation core in the sequence, and can be welded with the first heat dissipation core to form an independent circulation space. The water inlet chamber 220 is disposed between adjacent ribs 310 of the end mainboard 300 of the last heat dissipation core in the sequence; wherein, the side of the water inlet chamber 220 close to the reversing chamber 230 or the water outlet chamber 210 is an open chamber with an opening, and the opening cooperates with the outside of the reversing chamber 230 or the water outlet chamber 210, and can be welded with the reversing chamber 230 or the water outlet chamber 210 to form an independent circulation space on the heat dissipation core. The reversing chamber body 230 spans between adjacent ribs 310 of two main boards 300 on the same side of two adjacent layers of heat dissipation cores 100, and connects two independent circulation spaces through argon arc welding.

[0026] The locations of the water outlet chamber 210 and the water inlet chamber 220 ensure that the coolant can flow through each heat dissipation core in sequence, thereby absorbing and releasing heat at each stage. The presence of the reversing chamber 230 helps to change the flow direction of the coolant, so that the coolant can circulate effectively between different heat dissipation cores, further improving the heat exchange efficiency.

[0027] The coolant that absorbs the heat of the high-temperature components flows from the water inlet chamber 220 into the first heat dissipation core, and begins to perform forced heat exchange with the external cooling medium through the core. After initial heat dissipation, the coolant enters the reversing chamber 230, where the flow is directed so that it flows through the next heat dissipation core 100. The coolant continues to flow through other heat dissipation cores 100, and again performs heat exchange with the external cooling medium through the core. Finally, the coolant that has passed through multiple heat dissipation cores 100 and released heat flows out through the water outlet chamber 210, and again cools the heat dissipated by the operation of the high-temperature components to ensure the thermal balance of the normal operation of the system.

[0028] In some embodiments, a water outlet pipe 211 is disposed on the water outlet chamber body 210 , and one end of the water outlet pipe 211 extends into the water outlet chamber body 210 and communicates with the water outlet chamber body 210 .

[0029] By arranging the water outlet pipe 211 on the water outlet chamber body 210, it is ensured that the coolant can continuously enter the heat exchanger system. The water pipe 211 extends directly into the water outlet chamber body 210, providing a direct and concise coolant entry path. This design simplifies the layout of the entire cooling system, reduces additional pipes and connectors, and the coolant enters the water outlet chamber body 210 through the water outlet pipe 211. One end of the water outlet pipe 211 is connected to an external coolant source, and the other end extends into the water outlet chamber body 210, ensuring that the coolant can smoothly flow into the water tank.

[0030] In some embodiments, a water inlet pipe 221 is provided on the water inlet chamber body 220, and the water inlet pipe 221 passes through the water outlet chamber body 210 and communicates with the water inlet chamber body 220, or passes through the water outlet chamber body 210 and the reversing chamber body 230 and communicates with the water inlet chamber body 220, or passes through the reversing chamber body 230 and communicates with the water inlet chamber body 220.

[0031] The design of the water inlet chamber 220 and the water inlet pipe 221 in the integrated core heat exchanger, especially when there are multiple heat dissipation cores, the water inlet pipe 221 can be arranged in different ways to adapt to different system requirements. By allowing the water inlet pipe 221 to pass through the water outlet chamber 210, the reversing chamber 230 and the water inlet chamber 220 in different ways, or by providing partitions inside the water outlet chamber 210, the reversing chamber 400 and the water inlet chamber 300 to provide the required flow direction, a high degree of flexibility is provided for the design. This design allows the integrated core heat exchanger to adapt to different installation spaces and cooling requirements, simplifying system design and optimizing thermal management.

[0032] In some embodiments, the heat dissipation core 100 is composed of a plurality of plate-shaped heat dissipation tubes, and the heat dissipation tubes are connected to the water outlet chamber 210 , the water inlet chamber 220 or the reversing chamber 230 through the connection of the main board 300 .

[0033] The heat dissipation pipe is directly connected to the water outlet chamber body 210, the water inlet chamber body 220 or the reversing chamber body 230, which simplifies the flow path of the coolant inside the heat exchanger, reduces fluid resistance and pressure loss, and improves the overall efficiency of the system.

[0034] In some embodiments, a heat dissipation belt is provided between adjacent plate-shaped heat dissipation tubes.

[0035] The setting of heat dissipation belts can provide additional heat exchange area between the plate-shaped heat pipes, thereby enhancing the overall heat dissipation performance. These heat dissipation belts help to conduct and dissipate heat more effectively, further improving the heat exchange efficiency of the heat exchanger. The heat dissipation belts can promote the distribution of heat between adjacent heat pipes, reduce the possibility of local overheating, and ensure more uniform heat dissipation.

[0036] After the heated coolant enters the system through the water inlet tank 210, it flows through the heat dissipation pipe and absorbs heat and heats up with the heat dissipation belt. With the setting of the heat dissipation belt, the heat is transferred to the heat dissipation belt, thereby improving the efficiency of heat exchange.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
