Abstract

This utility model discloses a detachable plate heat exchanger that is easy to clean. It includes two sets of side plates, with four symmetrically arranged crossbars fixedly connected between them. Clamping plates are slidably connected to the outer walls of the crossbars. An unfolding assembly is provided on the outer walls of the crossbars, comprising an upper crossbar and a lower crossbar. The upper crossbar is slidably connected to the outer walls of the two upper crossbars, and the lower crossbar is slidably connected to the outer surfaces of the two lower crossbars. Grooves are formed on the bottom surface of the upper crossbar and the surface of the lower crossbar. This easy-to-clean detachable plate heat exchanger, by rotating a screw, drives the clamping plates to slide along the crossbars, releasing the clamping of the unfolding assembly. Multiple upper and lower crossbars can unfold outwards along the crossbars due to the linkage of hinge plate one and hinge plate two, increasing the spacing between the heat exchange plates and facilitating observation of dirt on the plate surfaces.

Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, specifically to a detachable plate heat exchanger that is easy to clean. Background Technology

[0002] Plate heat exchangers are a new type of high-efficiency heat exchanger composed of a series of metal plates with a specific corrugated shape. They can be used for refrigerant-cooling fluid heat exchange and water-water heat exchange. Plate heat exchangers have higher heat exchange efficiency, making them more compact and lighter. They are widely used in air conditioning systems for new energy vehicles, as well as battery and motor cooling subsystems, and can also be applied in the chemical industry. The basic principle of a plate heat exchanger is that multiple heat exchange plates form spaced-apart flow channels, and two heat exchange media exchange heat through the heat exchange plates in these channels.

[0003] According to the publicly disclosed easy-to-clean plate heat exchanger (Announcement No.: CN222505083U), the above application uses two fixed rods fixedly installed between the support column and the fixed clamping plate. The fixed rods are made of metal round rods and are installed in parallel vertically. Rollers are provided at the top of the movable clamping plate and ball bearings are provided at the bottom of the movable clamping plate, so that it can slide better on the fixed rods. Semi-circular moving grooves are provided at both the top and bottom of the heat dissipation plate. This not only can the heat dissipation plate be stably placed between the first and second fixed rods, but also maintain better stability. Compared with the T-shaped mounting groove of the transmission, it has better disassembly, more practicality and higher efficiency.

[0004] During the use of plate heat exchangers, not all heat exchange plates will become fouled. Therefore, it is necessary to inspect the fouling of individual heat exchange plates. In the above application, after removing the fixing of all heat exchange plates, it is necessary to move the heat exchange plates one by one, resulting in low cleaning efficiency of the heat exchange plates. Summary of the Invention

[0005] The purpose of this invention is to provide a detachable plate heat exchanger that is easy to clean, so as 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 plate heat exchanger that is easy to clean, comprising two sets of side plates, four sets of symmetrically arranged crossbars fixedly connected between the two sets of side plates, clamping plates slidably connected to the outer walls of the crossbars, and an unfolding assembly provided on the outer walls of the crossbars, the unfolding assembly comprising an upper crossbar and a lower crossbar, the upper crossbar slidably connected to the outer walls of the two upper sets of crossbars, the lower crossbar slidably connected to the outer surfaces of the two lower sets of crossbars, grooves being provided on the bottom surface of the upper crossbar and the surface of the lower crossbar, heat exchange plates being inserted into the grooves, and positioning grooves being provided on the top of the heat exchange plates, with multiple sets of upper and lower crossbars provided, and multiple sets of upper and lower crossbars arrayed on the outer walls of the crossbars, the multiple sets of upper crossbars and the multiple sets of lower crossbars being hinged to each other by a hinge plate one and a hinge plate two.

[0007] Preferably, a limiting component is provided on the side wall of the upper horizontal plate. The limiting component includes a through groove, which is provided on the side wall of the upper horizontal plate. A pressure plate is slidably connected inside the through groove. An insert is fixedly connected to the bottom surface of the pressure plate. The insert extends through and into a groove on the bottom surface of the upper horizontal plate. The insert is inserted into the inside of the positioning groove.

[0008] Preferably, a lead screw is rotatably connected to the side wall of the clamping plate, the lead screw passes through and is rotatably connected to the side wall of a set of side plates, and a rotating wheel is fixedly connected to the end of the lead screw.

[0009] Preferably, a flange is fixedly connected to the side wall of another set of the side plates.

[0010] Preferably, the two sets of upper and lower horizontal plates near the two sets of side plates are hinged to each other by the same hinge plate one and hinge plate two.

[0011] Preferably, the surface of the pressure plate is elastically connected to the inner wall of the through groove by a reset spring.

[0012] Preferably, a U-shaped rod is fixedly connected to the surface of the pressure plate, and the U-shaped rod passes through and is slidably connected to the surface of the upper horizontal plate.

[0013] Compared with the prior art, this utility model provides a detachable plate heat exchanger that is easy to clean, and has the following beneficial effects: 1. This easy-to-clean detachable plate heat exchanger uses a rotating wheel and screw to drive the clamping plate to slide along the crossbar, releasing the clamping state of the unfolding components. Multiple upper and lower crossbars can unfold outward along the crossbar due to the linkage of hinge plate one and hinge plate two, increasing the spacing between the heat exchange plates and making it easier to observe whether there is dirt on the surface of the heat exchange plates.

[0014] 2. This easy-to-clean detachable plate heat exchanger allows you to lift the dirty heat exchange plate upwards to align it with the U-shaped rod on the horizontal plate. This causes the pressure plate to move upwards against the spring force of the return spring, disengaging the insertion block from the positioning groove and releasing the lock on the heat exchange plate. The dirty heat exchange plate can then be pulled out of the groove without disassembling adjacent heat exchange plates. Afterwards, you can directly clean the surface dirt of the heat exchange plate with a cleaning tool. Attached Figure Description

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a detachable plate heat exchanger that is easy to clean, including two sets of side plates 1. Four sets of symmetrically arranged crossbars 2 are fixedly connected between the two sets of side plates 1. Clamping plates 21 are slidably connected to the outer walls of the crossbars 2. A lead screw 3 is rotatably connected to the side wall of one set of side plates 1. The lead screw 3 passes through and is rotatably connected to the side wall of one set of side plates 1. A rotating wheel 31 is fixedly connected to the end of the lead screw 3. The two sets of side plates 1 are fixedly connected by the four sets of symmetrical crossbars 2 to form a rigid frame. The clamping plates 21 are slidably connected to the outer walls of the crossbars 2. The rotating wheel 31 facilitates manual rotation of the lead screw 3. The lead screw 3 drives the clamping plates 21 to move axially, thereby achieving the pressing and releasing of multiple sets of heat exchange plates 54. A flange 4 is fixedly connected to the side wall of the other set of side plates 1. The flange 4 is used to connect external fluid pipes to form a closed flow channel.

[0018] like Figures 1-4As shown, an unfolding assembly 5 is provided on the outer wall of the crossbar 2. The unfolding assembly 5 includes an upper crossbar 51 and a lower crossbar 52. The upper crossbar 51 is slidably connected to the outer wall of the two upper crossbars 2, and the lower crossbar 52 is slidably connected to the outer surface of the two lower crossbars 2. Grooves 53 are provided on the bottom surface of the upper crossbar 51 and the surface of the lower crossbar 52. Heat exchange plates 54 are inserted into the inside of the grooves 53. Positioning grooves 55 are provided on the top of the heat exchange plates 54. Multiple sets of upper crossbars 51 and lower crossbars 52 are provided, and multiple sets of upper crossbars 51 and lower crossbars 52 are arrayed on the outer wall of the crossbar 2. Multiple sets of upper crossbars 51 and multiple sets of lower crossbars 52 are hinged to each other by hinge plate one 56 and hinge plate two 57. The two sets of upper crossbars 51 and lower crossbars 52 close to the two sets of side plates 1 are hinged to each other by the same hinge plate one 56 and hinge plate two 57. The upper horizontal plate 51 and the lower horizontal plate 52 are slidably connected to the upper and lower horizontal bars 2, respectively. The groove 53 is used to insert the heat exchange plates 54. Multiple sets of upper horizontal plates 51 and lower horizontal plates 52 are hinged end to end by hinge plate 1 56 and hinge plate 2 57 to form a "foldable" array. When the clamping plate 21 is released, multiple sets of upper horizontal plates 51 and lower horizontal plates 52 can be unfolded outward along the horizontal bar 2, thereby expanding the spacing between multiple sets of heat exchange plates 54 and making it easier to check the fouling of the heat exchange plates 54.

[0019] like Figures 1-4 As shown, a limiting component 6 is provided on the side wall of the upper horizontal plate 51. The limiting component 6 includes a through groove 61, which is provided on the side wall of the upper horizontal plate 51. A pressure plate 62 is slidably connected inside the through groove 61. An insert block 63 is fixedly connected to the bottom surface of the pressure plate 62. The insert block 63 penetrates and extends into the groove 53 on the bottom surface of the upper horizontal plate 51. The insert block 63 is inserted into the inside of the positioning groove 55. The surface of the pressure plate 62 is elastically connected to the inner wall of the through groove 61 by a return spring 64. A U-shaped rod 65 is fixedly connected to the surface of the pressure plate 62. The U-shaped rod 65 penetrates and is slidably connected to the surface of the upper horizontal plate 51. When the pressure plate 62 is pressed down, the insert block 63 is inserted into the positioning groove 55. The elastic pressure of the return spring 64 keeps the insert block 63 locked to the positioning groove 55, ensuring the stability of the heat exchange plate 54. The U-shaped rod 65 protrudes from the surface of the upper horizontal plate 51, making it easy to manually lift the pressure plate 62 to release the locking of the insert block 63 on the heat exchange plate 54, so that the heat exchange plate 54 can be removed individually without disassembling the adjacent heat exchange plate 54, which facilitates the disassembly and assembly of the heat exchange plate 54.

[0020] In this invention, during use, the screw 3 is first rotated via the rotating wheel 31, driving the clamping plate 21 to slide along the crossbar 2, thus releasing the clamping state on the unfolding assembly 5. At this time, due to the linkage of the hinge plate 1 56 and the hinge plate 2 57, the multiple sets of upper crossbars 51 and lower crossbars 52 can unfold outward along the crossbar 2, increasing the spacing between the heat exchange plates 54 and facilitating observation of whether there is dirt on the surface of the heat exchange plates 54.

[0021] If a heat exchange plate 54 needs cleaning, simply pull up the U-shaped rod 65 on the corresponding horizontal plate 51. This will cause the pressure plate 62 to move upward against the spring force of the return spring 64, disengaging the insertion block 63 from the positioning groove 55 and releasing the lock on the heat exchange plate 54. At this point, the heat exchange plate 54 can be directly pulled out from the groove 53 without disassembling adjacent heat exchange plates 54. Then, use cleaning tools to directly remove dirt from the surface of the heat exchange plate 54.

[0022] After cleaning, the heat exchange plate 54 is reinserted into the groove 53, the positioning groove 55 is aligned with the insert block 63, the U-shaped rod 65 is released, and the return spring 64 pushes the pressure plate 62 down, so that the insert block 63 is locked into the positioning groove 55. Finally, the rotating wheel 31 is rotated, and the clamping plate 21 is reset through the lead screw 3, pressing the unfolding assembly 5 and restoring the heat exchanger to normal working condition.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
