Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger core connection structure. Background Technology
[0002] In the field of heat exchangers, the heat exchanger core is the core component for achieving heat exchange. The performance and reliability of its connection structure have a crucial impact on the operating efficiency, stability, and service life of the entire heat exchange system. If the fluid entering the heat exchanger core is not effectively filtered, impurities in the fluid will gradually deposit in the microchannels of the heat exchanger core during the heat exchange process, causing microchannel blockage. This will not only significantly reduce heat exchange efficiency and increase energy consumption, but also lead to increased pressure inside the heat exchanger, threatening the safe operation of the equipment. Utility Model Content
[0003] The purpose of this utility model is to provide a heat exchanger core connection structure to solve the problem mentioned in the background art that if the fluid entering the heat exchanger core is not effectively filtered, impurities in the fluid will gradually deposit in the microchannels of the heat exchanger core during the heat exchange process, causing microchannel blockage. This will not only significantly reduce heat exchange efficiency and increase energy consumption, but also lead to increased pressure inside the heat exchanger, threatening the safe operation of the equipment.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger core connection structure, comprising:
[0005] Heat exchanger core;
[0006] There are two No. 1 inlet / outlet main pipes. The No. 1 inlet / outlet main pipe is connected to the heat exchanger core. Two No. 2 inlet / outlet main pipes are provided on one side of the heat exchanger core. A No. 1 connecting pipe is fixed to both the No. 1 inlet / outlet main pipe and the No. 2 inlet / outlet main pipe.
[0007] A metal hose is installed at one end of a first connecting pipe, and a second connecting pipe is installed at the other end of the metal hose. One end of the second connecting pipe is fixedly installed with a first inlet pipe via a flange.
[0008] The filter housing is fixed to one end of the No. 1 water inlet pipe;
[0009] A connecting cover is threaded onto one side of the filter housing, and a filter element is installed on the inner side of the filter housing and the connecting cover.
[0010] As a preferred embodiment of this utility model: one end of the first connecting pipe and the second connecting pipe are both fixedly connected to a connecting insert, both ends of the metal flexible tube are both fixedly connected to an external threaded pipe, and one end of the first connecting pipe and the second connecting pipe is rotatably provided with an internal threaded rotating sleeve that mates with the external threaded pipe.
[0011] As a preferred embodiment of this utility model: an inner sealing groove is provided on the inner side of the externally threaded pipe, and the inner sealing groove cooperates with the connecting tube.
[0012] As a preferred embodiment of this utility model, a second water inlet pipe is fixedly connected to one side of the connecting cover.
[0013] As a preferred embodiment of this utility model: the connecting cover has a communicating cavity inside, and the connecting cover has multiple side openings at equal intervals inside, the side openings are connected to the communicating cavity, and the second water inlet pipe is connected to the communicating cavity.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses the internal thread rotating sleeve to engage with the external thread pipe threads at both ends of the metal hose, allowing the metal hose to be quickly connected or disconnected from the No. 1 connecting pipe and the No. 2 connecting pipe, simplifying the installation and maintenance process. It also facilitates the pairing and locking of multiple interfaces, providing a flexible connection. The inner sealing groove on the inner side of the external thread pipe tightly engages with the connecting insert to form a radial sealing structure. Combined with the mechanical compression effect of the threaded connection, this significantly reduces the risk of fluid leakage. The design of the internal connecting cavity and the equidistant side openings of the connecting cover ensures that the fluid is evenly dispersed to the surface of the filter element after entering from the No. 2 inlet pipe, maximizing the utilization rate of the entire cross-section of the filter element and guaranteeing heat exchange efficiency and equipment life.

[0022] 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.
[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a heat exchanger core connection structure, comprising: a heat exchanger core 1; two primary inlet / outlet manifolds 2, which are connected to the heat exchanger core 1 via pipes; two secondary inlet / outlet manifolds 4 are connected to one side of the heat exchanger core 1 via pipes; a primary connecting pipe 3 is fixedly connected to both the primary and secondary inlet / outlet manifolds 2 and 4; a metal flexible hose 5 is installed at one end of the primary connecting pipe 3, and a secondary connecting pipe 7 is installed at the other end of the metal flexible hose 5; a primary water inlet pipe 12 is fixedly installed at one end of one of the secondary connecting pipes 7 via a flange; a filter shell 13 is fixedly connected to one end of the primary water inlet pipe 12; a connecting cover 15 is threaded onto one side of the filter shell 13, and a filter element 14 is installed inside the filter shell 13 and the connecting cover 15.
[0024] It should be noted that in this embodiment, the fluid to be treated enters the communicating cavity 16 inside the connecting cover 15 through the second inlet pipe 6. The communicating cavity 16 distributes the fluid to multiple side ports 17. The equidistant distribution of the side ports ensures that the fluid evenly covers the entire cross-section of the filter element 14, avoiding excessively high local flow rates that could lead to a decrease in filtration efficiency. When the fluid passes through the filter element 14, impurities are trapped on the surface of the filter element, and the cleaning fluid enters the inside of the filter shell 13, and then exits through the first inlet pipe 12. The cleaning fluid enters the second connecting pipe 7 through the first inlet pipe 12, and is flexibly connected to the first connecting pipe 3 through the metal hose 5. The internal threaded rotating sleeve 9 is threadedly engaged with the external threaded pipes 10 at both ends of the metal hose to achieve quick connection or Separation simplifies maintenance. The inner sealing groove 11 fits tightly with the connecting pipe 8 to form a radial sealing structure. Combined with the mechanical clamping effect of the threaded connection, it provides double protection against fluid leakage. The filtered clean fluid enters the first inlet / outlet manifold 2 through the first connecting pipe 3 and is distributed to the internal flow channel of the heat exchanger core 1. On the other side, the fluid that has completed heat exchange is output through the second inlet / outlet manifold 4, forming an independent loop. The cold / hot media are separated. The cold and hot fluids undergo efficient heat transfer through fins in the heat exchanger core 1 to achieve temperature regulation. The fluid is filtered before entering the core to avoid impurities clogging the microchannels, ensuring heat exchange efficiency and equipment life. The filter element 14 can be quickly replaced by rotating and disassembling the connecting cover 15.
[0025] In one embodiment, such as Figures 1 to 6 As shown, one end of the first connecting pipe 3 and the second connecting pipe 7 are both fixedly connected to a connecting tube 8, and both ends of the metal flexible tube 5 are both fixedly connected to an external threaded tube 10. One end of the first connecting pipe 3 and the second connecting pipe 7 is rotatably provided with an internal threaded rotating sleeve 9 that mates with the external threaded tube 10.
[0026] It should be noted that in this embodiment, the metal hose 5 can be quickly connected or separated from the first connecting pipe 3 and the second connecting pipe 7 by the threaded engagement of the internal thread rotating sleeve 9 and the external thread pipe 10, simplifying the installation and maintenance process. In the case of multiple interfaces, a soft connection is provided to facilitate the locking of the mating interfaces.
[0027] In one embodiment, such as Figures 1 to 6 As shown, an inner sealing groove 11 is provided on the inner side of the external threaded pipe 10, and the inner sealing groove 11 cooperates with the connecting insertion pipe 8.
[0028] It should be noted that in this embodiment, the tight fit between the inner sealing groove 11 and the connecting tube 8 forms a radial sealing structure, which, combined with the mechanical clamping effect of the threaded connection, significantly reduces the risk of fluid leakage.
[0029] In one embodiment, such as Figures 1 to 6 As shown, a second water inlet pipe 6 is fixedly connected to one side of the connecting cover 15.
[0030] It should be noted that in this embodiment, the second water inlet pipe 6 provides an independent water inlet channel, through which the water enters the connecting cover 15 and the filter shell 13, and is filtered by the internal filter element 14.
[0031] In one embodiment, such as Figures 1 to 6 As shown, the connecting cover 15 has a connecting cavity 16 inside, and multiple side openings 17 are equally spaced inside the connecting cover 15. The side openings 17 are connected to the connecting cavity 16, and the second water inlet pipe 6 is connected to the connecting cavity 16.
[0032] It should be noted that, in this embodiment, the design of the connecting cavity 16 and the equidistant side openings 17 allows the fluid to be evenly dispersed onto the surface of the filter element 14 after entering from the second water inlet pipe 6. The evenly distributed side openings 17 ensure that the utilization rate of the entire cross-section of the filter element 14 is maximized.
