Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically to a detachable and combinable heat exchanger. Background Technology
[0002] A heat exchanger, also known as a heat exchanger, is a device used to transfer heat from one medium to another. It achieves heat transfer between two or more fluids at different temperatures to meet various process requirements while improving energy efficiency.
[0003] For example, the utility model application with application number 202123240936.6 discloses a detachable plate heat exchanger. Heat exchangers similar to the above application still have the following shortcomings: during the disassembly and assembly process, the side plate needs to be removed before the heat exchange plates can be disassembled or assembled, which is relatively troublesome.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a detachable and combinable heat exchanger. Utility Model Content
[0005] The purpose of this invention is to provide a detachable and combinable heat exchanger to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and combinable heat exchanger, comprising a base plate, a limiting assembly, and heat exchange plates. A lower frame is fixed to the middle of the base plate, and a fixing plate is fixed to one side of the lower frame. An upper frame is installed on the upper side of the fixing plate. Limiting assemblies are installed on both the front and rear sides of the upper frame. The limiting assembly includes a connecting plate, an upper plate, a telescopic rod, and a locking strip. The upper plate is fixedly connected to both the front and rear sides of the upper frame through the connecting plate. A telescopic rod is installed on the lower side of the upper plate, and a locking strip is fixed to the bottom of the telescopic rod. Two end plates are installed on the upper side of the base plate, and heat exchange plates are arranged between the end plates. A locking groove is opened on the upper side of the end plates and heat exchange plates corresponding to the locking strip.
[0007] Furthermore, the upper frame and the lower frame are parallel to each other, and limit rods are installed inside both the lower frame and the upper frame.
[0008] Furthermore, the card slot is a rectangular slot, and the size of the card slot matches that of the card strip.
[0009] Furthermore, the end plate and heat exchange plate each have four mounting slots inside, and heat exchange tubes are installed inside the mounting slots. An external pipe is connected to the outer side of the heat exchange tube via a flange.
[0010] Furthermore, a long bolt runs through the upper side between the two end plates on the left and right sides, and two long bolts are installed symmetrically, with nuts fitted at both ends of the long bolts.
[0011] Furthermore, limit rings are fixed at the upper and lower ends of the middle part of the left and right end plates, and the limit rings at the upper and lower ends are slidably connected to the limit rods in the upper frame and lower frame, respectively.
[0012] Furthermore, limit strips are fixed on both the front and rear sides of the upper side of the base plate, and limit grooves are opened on the lower side of the end plate and heat exchange plate corresponding to the positions of the limit strips.
[0013] Furthermore, the limiting groove and the limiting strip are slidably connected, and the limiting strip is a rectangular strip.
[0014] This utility model provides a detachable and combinable heat exchanger, which has the following advantages:
[0015] This utility model is equipped with a limiting component. The cooperation of the limiting strip and limiting groove on the lower side, and the cooperation of the locking strip and locking groove on the upper side, ensures stable installation of the end plate and heat exchange plates. The telescopic rod facilitates the up and down movement of the locking strip, allowing it to be embedded into the locking groove position on the upper side of the end plate and heat exchange plates. This installation method is relatively convenient. Conversely, when disassembly is required, the locking strip can be raised to release the limiting structure. At this time, any heat exchange plate in the middle of the end plate can be disassembled to increase or decrease the number of heat exchange plates.
[0016] This utility model is equipped with heat exchange plates. The heat exchange tube and several heat exchange plates can achieve heat exchange. The limiting rings on the upper and lower sides of the end plate slide with the limiting rods in the upper and lower frames, respectively, so that the limiting rods can limit the end plate and improve the installation stability of the end plate. The two long bolts on the upper side are convenient for locking and fixing the two end plates, eliminating the need to set multiple long bolts on the side that are inconvenient to disassemble.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example
[0022] like Figure 1 and Figure 2 As shown, a detachable and combinable heat exchanger includes a base plate 1, a limiting assembly 6, and heat exchange plates 8. A lower frame 2 is fixed to the middle of the base plate 1, and a fixing plate 3 is fixed to one side of the lower frame 2. An upper frame 4 is installed on the upper side of the fixing plate 3. Limiting assemblies 6 are installed on both the front and rear sides of the upper frame 4. The limiting assembly 6 includes a connecting plate 601, an upper plate 602, a telescopic rod 603, and a retaining strip 604. The upper plate 602 is fixedly connected to both the front and rear sides of the upper frame 4 through the connecting plate 601. A telescopic rod 603 is installed on the lower side of the upper plate 602, and a retaining strip 604 is fixed to the bottom of the telescopic rod 603. Two end plates 7 are installed on the upper side of the base plate 1, and a heat exchange plate is arranged between the end plates 7. The upper sides of the plate 8, end plate 7, and heat exchange plate 8 are provided with slots 10 corresponding to the positions of the retaining strips 604. The slots 10 are rectangular and their dimensions match those of the retaining strips 604. The connecting plates 601 on the front and rear sides of the upper frame 4 facilitate the support and fixation of the upper plate 602. The telescopic rod 603 facilitates the up and down movement of the retaining strips 604, allowing them to be inserted into the slots 10 on the upper sides of the end plate 7 and heat exchange plate 8. This installation method is relatively convenient. Conversely, when disassembly is required, the retaining strips 604 can be raised to release the limiting structure. At this time, any heat exchange plate 8 in the middle of the end plate 7 can be disassembled to increase or decrease the number of heat exchange plates 8, making it quite flexible in use. Example
[0023] like Figure 1 and Figure 3As shown, the upper frame 4 and the lower frame 2 are parallel to each other, and limit rods 5 are installed inside both the lower frame 2 and the upper frame 4. Long bolts 11 pass through the upper side between the two end plates 7, and two long bolts 11 are symmetrically installed. Nuts are fitted on both ends of the long bolts 11. Limit rings 12 are fixed at the upper and lower ends of the middle of the two end plates 7. The limit rings 12 at the upper and lower ends are slidably connected to the limit rods 5 in the upper frame 4 and the lower frame 2, respectively. Limit strips 13 are fixed on the front and rear sides of the upper side of the bottom plate 1. At the same time, limit grooves 14 are opened on the lower side of the end plates 7 and the heat exchange plates 8 at the positions corresponding to the limit strips 13. The limit grooves 14 are slidably connected to the limit strips 13, and the limit strips 13 are rectangular strips. Each end plate 7 has four mounting slots 9, and heat exchange tubes 15 are installed inside the mounting slots 9. An external pipe 16 is connected to the outside of the heat exchange tube 15 through a flange. The heat exchange tube 15, together with several heat exchange plates 8, can achieve heat exchange. The limiting rings 12 on the upper and lower sides of the end plate 7 slide with the limiting rods 5 in the upper frame 4 and the lower frame 2, respectively, so that the limiting rods 5 can limit the end plate 7 and improve the installation stability of the end plate 7. The two long bolts 11 on the upper side are convenient for locking and fixing the two end plates 7. The cooperation of the limiting strip 13 and the limiting groove 14 on the lower side, as well as the cooperation of the locking strip 604 and the locking groove 10 on the upper side, makes the end plate 7 and the heat exchange plates 8 installed stably, without the need to set multiple long bolts 11 on the side that are inconvenient to disassemble.
[0024] In summary, as Figures 1-3 As shown, in use, the detachable heat exchanger allows the limiting rings 12 on the upper and lower sides of the end plate 7 to slide against the limiting rods 5 in the upper frame 4 and lower frame 2 respectively, thereby installing the two end plates 7. Then, the heat exchange plates 8 and heat exchange tubes 15 are set and connected to the external pipe 16. Then, the two long bolts 11 on the upper side can lock and fix the two end plates 7. At this time, the mutual cooperation of the limiting strip 13 and limiting groove 14 on the lower side and the mutual cooperation of the locking strip 604 and locking groove 10 on the upper side make the end plate 7 and heat exchange plates 8 installed stably, without the need to set multiple long bolts 11 on the side that are inconvenient to disassemble.
[0025] During use, the heat exchange tube 15, together with several heat exchange plates 8, can achieve heat exchange. When it is necessary to disassemble or assemble the heat exchange plates 8, the long bolt 11 can be loosened, and then the telescopic rod 603 can be used to drive the locking strip 604 to move up and down, so that the locking strip 604 can rise away from the end plate 7 and the locking groove 10 on the upper side of the heat exchange plate 8, thus releasing the limiting structure. At this time, any heat exchange plate 8 in the middle of the end plate 7 can be disassembled to increase or decrease the number of heat exchange plates 8. This completes the use process of the detachable combined heat exchanger.
