Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchangers, and more particularly to a heat exchanger. Background Technology
[0002] A heat exchanger is a device used for heat exchange, primarily for heating or cooling fluids. It achieves efficient energy utilization by transferring heat from one fluid to another and is widely used in chemical engineering, HVAC systems, power generation, and refrigeration. Heat exchangers come in various designs, including shell-and-tube, plate, and air-cooled types.
[0003] A conventional heat exchanger includes a first manifold, a second manifold, a harmonica tube, fins, a fixing plate located between the first and second manifolds, and plugs or joints at both ends of the first and second manifolds. Conventional heat exchangers are mostly single-layer structures. When encountering high-power heat exchange requirements, it is often necessary to increase the size of the heat exchanger to enhance the heat exchange effect. When space is limited, it is necessary to consider a double-layer or multi-layer heat exchanger structure. Therefore, a heat exchanger is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a heat exchanger that aims to improve the problem in the prior art where the size of the heat exchanger needs to be increased to enhance the heat exchange effect when encountering high-power heat exchange requirements.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A heat exchanger includes a left heat exchanger and a right heat exchanger disposed on the side wall of the left heat exchanger. A heat exchange core is fixedly connected to the side wall of both the left heat exchanger and the right heat exchanger. An inlet and outlet liquid pipe is fixedly connected to one side of both the left heat exchanger and the right heat exchanger.
[0007] As a further description of the above technical solution:
[0008] The left heat exchanger and the right heat exchanger are both fixedly connected to the sidewalls of the mounting brackets.

The sidewalls of the heat exchange cores are provided with connecting components for connecting the heat exchange cores on both sides.
[0009] As a further description of the above technical solution:
[0010] The connecting assembly includes a male end bracket and a female end bracket. The side wall of the male end bracket is fixedly connected to the side wall of the heat exchange core on the left side, and the side wall of the female end bracket is fixedly connected to the side wall of the heat exchange core on the right side.
[0011] As a further description of the above technical solution:
[0012] Both the male end bracket and the female end bracket are assembled by fitting the bottom bracket planes of two heat exchange cores together. The female end bracket has a certain gap to accommodate the insertion of the male end bracket. Both the male end bracket and the female end bracket have several waist holes arranged in an array inside.
[0013] As a further description of the above technical solution:
[0014] The heat exchange core is provided with a fan hood on its side wall, and a fixed bracket is fixedly connected to the side wall of the fan hood. The fixed bracket is fixedly connected to the mounting bracket by screws.
[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:
[0018] A cooling fan is fixedly connected inside the protective cover, and a fixing block is fixedly connected to the side wall of the protective cover.
[0019] As a further description of the above technical solution:
[0020] The inlet and outlet pipes are rotatably connected to a connecting pipe. The connecting pipe is made of copper and is C-shaped with both ends bent at 90 degrees and flared. The inner diameter of the flared ends is greater than or equal to the outer diameter of the inlet and outlet pipe manifold.
[0021] This utility model has the following beneficial effects:
[0022] In this invention, the working medium enters the heat exchange core from the inlet and outlet pipes of the left heat exchanger and flows out from the inlet and outlet pipes of the other end. It then flows to the right heat exchanger through the connecting pipe for heat exchange. The dissipated heat is carried away by the cooling fan and finally discharged through the inlet and outlet pipes, completing the circulating heat exchange. This solves the problem that when encountering high-power heat exchange requirements, it is necessary to increase the size of the heat exchanger in order to enhance the heat exchange effect. The above technical solution improves the practicality of the equipment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0030] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a heat exchanger, including a left-end heat exchanger 1, a right-end heat exchanger 2 disposed on the side wall of the left-end heat exchanger 1, and heat exchange cores 3 fixedly connected to the side walls of both the left-end heat exchanger 1 and the right-end heat exchanger 2. Inlet and outlet pipes 4 are fixedly connected to one side of both the left-end heat exchanger 1 and the right-end heat exchanger 2, respectively, for introducing or discharging liquid into or out of the equipment. Mounting brackets 5 are fixedly connected to the side walls of both the left-end heat exchanger 1 and the right-end heat exchanger 2, and are symmetrically arranged along the center line of the cores. Connecting components are disposed on the side walls of the heat exchange cores 3, for connecting the two heat exchange cores 3. The connecting components include a male-end bracket 6 and a female-end bracket 7. The side wall of the male-end bracket 6 is fixedly connected to the side wall of the left heat exchange core 3, and the side wall of the female-end bracket 7 is fixedly connected to the side wall of the right heat exchange core 3. Both the male-end bracket 6 and the female-end bracket 7 are formed by the bottom support planes of two heat exchange cores 3. The components are assembled by fitting together. The female end bracket 7 has a certain gap to accommodate the insertion of the male end bracket 6. Both the male end bracket 6 and the female end bracket 7 have several waist holes arranged in an array inside. The male end bracket 6 and the female end bracket 7 are connected and fixed with screws. The heat exchange core 3 has a fan shroud 8 on its side wall. The side wall of the fan shroud 8 is fixedly connected to a fixed bracket 9. The fixed bracket 9 and the mounting bracket 5 are fixedly connected by screws. The fan shroud 8 has a circular groove 10 inside. The side wall of the fan shroud 8 is provided with a protective cover 11. The protective cover 11 is used to protect the cooling fan 12. The cooling fan 12 is fixedly connected inside the protective cover 11. The cooling fan 12 is used to carry away and disperse heat. The side wall of the protective cover 11 is fixedly connected to a fixed block 13. The side wall of the inlet and outlet liquid pipe 4 is rotatably connected to a connecting pipe 14. The connecting pipe 14 is made of copper and is C-shaped with both ends bent at 90 degrees and flared at both ends. After flaring, the inner diameter is greater than or equal to the outer diameter of the inlet and outlet liquid pipe 4 manifold copper pipe.
[0031] During operation, the male support 6 on the heat exchange core 3 at the bottom of the left heat exchanger 1 and the female support 7 on the heat exchange core 3 at the bottom of the right heat exchanger 2 are first connected by screws. In this way, the two heat exchangers can be combined into a complete unit. In actual operation, the working medium enters the system from the inlet and outlet pipes 4 of the left heat exchanger 1 and flows into the interior of the two heat exchange cores 3 respectively. After sufficient heat exchange, the working medium flows out through the inlet and outlet pipes 4 at the other end and flows to the right heat exchanger 2 through the connecting pipe 14 to continue the heat exchange process. During this process, the heat in the working medium is dissipated through the fins. This dissipated heat is carried away and dispersed by the cooling fan 12 and then discharged from the heat exchanger through the inlet and outlet pipes 4. In this way, heat exchange is carried out in a cycle. In addition, the usage method can be flexibly selected according to the actual heat exchange power requirements. If only a small heat exchange power is required, the left heat exchanger 1 can be used alone, or the left heat exchanger 1 and the right heat exchanger 2 can be spliced together and used independently. When facing a larger heat exchange demand, the two heat exchangers can be connected in series through the connecting pipe 14. This can significantly improve the overall heat exchange performance and ensure that the system can efficiently complete the heat exchange task.
[0032] Working principle: When using this equipment, the male end bracket 6 on the bottom heat exchange core 3 of the left heat exchanger 1 and the female end bracket 7 on the bottom heat exchange core 3 of the right heat exchanger 2 are connected by screws to form a whole. During operation, the working medium enters from the inlet and outlet pipes 4 of the left heat exchanger 1, flows into the two heat exchange cores 3 respectively, and then flows out through the inlet and outlet pipes 4 at the other end. It flows to the right heat exchanger 2 through the connecting pipe 14 for heat exchange. The heat in the working medium is dissipated through the fins and then carried away by the cooling fan 12. Then it flows out of the heat exchanger through the inlet and outlet pipes 4. The heat exchange is circulated in this way. At the same time, depending on the heat exchange power requirements, the left heat exchanger 1 can be used alone, or the left heat exchanger 1 and the right heat exchanger 2 can be spliced together and used independently. When there is a high power heat exchange requirement, they can be used in series through the connecting pipe 14 to improve the heat exchange performance.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
