[0003] When the heat exchange capacity of the heat exchanger is too high or too low, the existing technology controls the heat exchange capacity by changing factors such as the unit's air volume, heat exchange area, the volume of heat exchange tubes and fins, and the temperature difference between the heat exchanger and the environment. However, this method will affect the heat exchanger's wind resistance, fan power consumption, system energy efficiency, and structural cost, and may easily cause the heat exchanger to have problems such as high wind resistance, high power consumption, low energy efficiency, and high processing cost.

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0039] like Figures 1-13 As shown, an embodiment of the present application provides a heat exchanger, comprising a first header 1, a second header 2, a mounting member 3, and a fin 4. The interior of the first header 1 is hollow to form a first chamber, and the interior of the second header 2 is hollow to form a second chamber. The first chamber and the second chamber are used to collect and uniformly distribute the incoming fluid. The extension directions of the first header 1 and the second header 2 are parallel and not in a straight line. At the same time, the first header 1 and the second header 2 are arranged side by side to form an installation space between the first header 1 and the second header 2.
[0040] A plurality of mounting members 3 are provided, for example, 10-20 mounting members 3 are provided. The plurality of mounting members 3 are all provided in the installation space between the first header 1 and the second header 2, wherein the extension directions of the plurality of mounting members 3 are parallel and not in a straight line, and the plurality of mounting members 3 are arranged along the extension direction of the first header 1 or the second header 2 so that the mounting members 3 can extend from the first header 1 to the second header 2.
[0041] There are multiple fins 4, which are connected to multiple mounting members 3, thereby increasing the heat exchange area and making the wind resistance across the heat exchanger surface more uniform. The fins 4 can be configured as corrugated shapes, with each fin 4 extending from the first header 1 to the second header 2 and connected between two adjacent mounting members 3, so that both sides of each mounting member 3 are connected to a fin 4, which is beneficial to improving the heat exchange efficiency. In addition, if Figure 12-13 As shown, the fins 4 can also be set to be plug-in type, each fin 4 extends along the arrangement direction of multiple mounting parts 3, and a mounting groove is provided on the fin 4. Multiple mounting parts 3 are all connected in the mounting groove of the same fin 4, so that multiple mounting parts 3 can be cooled at the same time by one fin 4.
[0042] It should be understood that the scheme protected by this application does not limit the arrangement structure of the first collecting pipe 1 and the second collecting pipe 2, the specific structure of the multiple fins 4, and the arrangement structure of the multiple mounting parts 3. They are only described here as an example scheme. In other schemes, the first collecting pipe 1 and the second collecting pipe 2 may not be parallel, and the multiple mounting parts may also not be parallel. It is only necessary to meet the requirement that the two ends of the mounting part 3 are respectively arranged on the first collecting pipe 1 and the second collecting pipe 2.
[0043] Among the multiple mounting parts 3, a portion is configured as a heat exchanger 5 and another portion is configured as a separator 6, that is, the heat exchanger 5 and the separator 6 are collectively referred to as the mounting parts 3. There are multiple heat exchangers 5, and the heat exchangers 5 are configured as a tubular structure. The two ends of the heat exchanger 5 are respectively connected to the first manifold 1 and the second manifold 2, so that the first manifold 1 and the second manifold 2 are connected through the heat exchanger 5. When the fluid flows through the heat exchanger 5, heat exchange is achieved through the fins 4 connected to the heat exchanger 5 and the wind passing through the surface of the heat exchanger. At least one separator 6 is provided, that is, one or more separators 6 can be provided, and the arrangement is adaptive according to the actual heat exchange requirements. The separator 6 is not connected to the first manifold 1 and the second manifold 2, and the fluid cannot flow through the separator 6. Although the separator 6 is also connected to the fins 4, the separator 6 only serves as a support and connection and cannot achieve heat exchange.
[0044] The heat exchanger 5 and the separator 6 are two parts of a plurality of connecting parts. By adjusting the relative ratio of the heat exchanger 5 and the separator 6, the heat exchange energy and heat exchange capacity of the heat exchanger can be adjusted. For example, when the heat exchange energy of the heat exchanger is too low, the ratio of the separator 6 to the heat exchanger 5 can be appropriately reduced. When the heat exchange capacity of the heat exchanger is too high, the ratio of the separator 6 to the heat exchanger 5 can be appropriately increased. Here, by gradually increasing or decreasing the number of separators 6, the heat exchange capacity of the heat exchanger can be gradually increased or decreased, while the overall wind resistance remains unchanged. By adjusting the number of separators 6 between adjacent heat exchangers 5, the separators 6 are arranged more evenly in the heat exchanger, which makes it easier to obtain a uniform and stable wind temperature.
[0045] With such a configuration, the heat exchange amount and wind resistance can be controlled within an appropriate range by adjusting the relative proportions of the heat exchange element 5 and the partition 6 in the heat exchanger. There is no need to adjust the air volume of the unit, change the volume of the heat exchanger, develop new heat exchange tubes and fins 4, or adjust the working point of the unit, which is conducive to maintaining the stable performance of the heat exchanger.
[0046] In this embodiment, the heat exchange elements 5 and the separators 6 are alternately arranged, i.e., one or more separators 6 are arranged on both sides of one or more heat exchange elements 5, and one or more heat exchange elements 5 are arranged on both sides of one or more separators 6, thereby facilitating improved heat exchange uniformity. The heat exchange elements 5 and separators 6 are described in detail below based on specific embodiments.
[0047] like Figure 3-10 As shown, in some embodiments, a separator 6 is provided between two adjacent heat exchange elements 5. Multiple separators 6 are provided, with a heat exchange element 5 provided on both sides of each separator 6, and a separator 6 is provided on both sides of each heat exchange element 5. Multiple fins 4 are provided and located between the heat exchange elements 5 and the separators 6. One side of the fin 4 is connected to the heat exchange element 5 and the other side is connected to the separator 6.
[0048] Among them, Figure 3-6 In the first embodiment shown, heat exchanger 5 is configured as a tubular structure, with its two ends inserted into and connected to first and second manifolds 1, 2, respectively, allowing fluid to flow through heat exchanger 5. Separator 6 is also inserted into and connected to first and second manifolds 1, 2, at its two ends. Separator 6 is not conductive at both ends; for example, separator 6 is configured as a solid profile, preventing it from conducting current between first and second manifolds 1, 2, and preventing fluid from flowing through it. Thus, by inserting separator 6, the existing sockets on first and second manifolds 1, 2 can be utilized, eliminating the need for additional processing on the first and second manifolds 1, 2. Separator 6 can simply replace the existing heat exchanger 5.
[0049] exist Figure 7-8 In the second embodiment shown, the difference from the first embodiment is that a first groove and a second groove are respectively provided at both ends of the separator 6. The shape of the first groove matches the shape of the outer wall of the first manifold 1, and the shape of the second groove matches the shape of the outer wall of the second manifold 2. For example, the first groove and the second groove are set in a crescent shape. During installation, the outer wall of the first manifold 1 is embedded in the first groove so that the outer wall of the first manifold 1 fits with the groove wall and groove bottom of the first groove. The outer wall of the second manifold 2 is embedded in the second groove so that the outer wall of the second manifold 2 fits with the groove wall and groove bottom of the second groove. This can prevent the separator 6, the first manifold 1, and the second manifold 2 from moving during the installation and connection process, thereby improving production efficiency.
[0050] exist Figure 9-10 The third embodiment shown differs from the first embodiment in that the ends of the separator 6 are spaced apart from the first and second headers 1, 2, respectively. In this case, the separator 6 is connected to the heat exchange element 5 via fins 4 to facilitate installation of the separator 6. Because there is a gap between the ends of the separator 6 and the first and second headers 1, 2, heat from the first and second headers 1, 2 is prevented from transferring to the separator 6, reducing unnecessary heat conduction and improving design and control accuracy.
[0051] In the second and third embodiments, since the separator 6 is not inserted into the first collecting pipe 1 and the second collecting pipe 2, the separator 6 can be made of the same material as the heat exchanger 5, that is, the separator 6 can be processed using the original heat exchange tube, which is beneficial to saving costs.
[0052] In another embodiment, multiple (e.g., two or three) separators 6 are provided between any two adjacent heat exchangers 5, thereby arranging the separators 6 in groups for easier installation. In this embodiment, fins 4 are connected between the heat exchangers 5 and the separators 6, and fins 4 are also connected between two adjacent separators 6.
[0053] like Figure 11 In the illustrated solution, every four heat exchangers 5 form a group, every two partitions 6 form a group, and multiple groups of heat exchangers 5 and multiple groups of partitions 6 are arranged alternately, that is, there are four heat exchangers 5 on both sides of two partitions 6 respectively.
[0054] In the above scheme, the spacing between two adjacent partitions 6 in the same group is L1, the spacing between adjacent partitions 6 and heat exchangers 5 in adjacent groups is L2, and the spacing between two adjacent heat exchangers 5 in the same group is L3, where L1 = L2 = L3. This ensures that the spacing between two adjacent mounting members 3 is consistent, facilitating manufacturing while also ensuring uniform wind resistance across the heat exchanger and preventing short-circuiting. The spacing between any two adjacent heat exchangers 5 is L, and the range of L is 20 mm < L < 50 mm. Furthermore, it is preferably 20 mm < L < 30 mm.
[0055] In addition, the heat exchanger 5 and separator 6 are both plate structures, and the thickness of the heat exchanger 5 and separator 6 is consistent. The thickness here refers to the thickness of the plate structure, thereby improving the appearance consistency of the heat exchanger 5 and separator 6. During installation, multiple heat exchangers 5 and separators 6 are arranged along their thickness direction.
[0056] like Figure 1As shown, in some schemes, the liquid inlet 7 and the liquid outlet 8 can be both set on the first manifold 1. During operation, the fluid in the first manifold 1 flows to the second manifold 2 through some heat exchange components 5, and the fluid in the second manifold 2 flows to the first manifold 1 through other heat exchange components 5. By increasing the flow path, the surrounding capacity is improved.
[0057] like Figure 2 As shown, in other schemes, a liquid inlet 7 is provided on the first manifold 1, and a liquid outlet 8 is provided on the second manifold 2. Through the design of the heat exchange component 5, the fluid on the first manifold 1 can flow to the second manifold 2, realizing heat exchange during the flow process.
