Description
Technical Field
[0001] This utility model relates to the field of heat exchangers, specifically a leak-proof heat exchanger. Background Technology
[0002] In industrial heat transfer processes, leakage in heat exchangers not only leads to media waste and reduced system efficiency, but can also cause safety hazards (such as leaks of flammable and explosive media) or environmental pollution (such as leaks of corrosive media). Leak-proof heat exchangers significantly reduce the risk of leakage through structural optimization, material upgrades, enhanced sealing, and monitoring and early warning technologies. They are suitable for high-value media, corrosive media, toxic and hazardous media, or scenarios requiring strict sealing (such as food, pharmaceutical, and chemical industries).
[0003] However, in existing plate heat exchangers, the heat exchange plates are connected to each other using a combination of gaskets and sealing grooves for sealing to prevent leakage. Over time, impurities in the input liquid can become embedded between the gaskets and sealing grooves, causing the gaskets to protrude or become damaged, reducing the sealing performance between the heat exchange plates. Furthermore, since the gaskets are placed one by one in the sealing grooves of the heat exchange plates, it is inconvenient to clean them individually, leading to a gradual decrease in the sealing performance between adjacent heat exchange plates. Therefore, we propose a leak-proof heat exchanger. Utility Model Content
[0004] The purpose of this utility model is to provide a leak-proof heat exchanger, including a U-shaped base. Guide rails are fixedly installed on the upper and lower side walls of the U-shaped base. Multiple heat exchange plates are fixedly installed at equal intervals between the two guide rails. A sealing assembly is sealed inside the heat exchange plates. A first limiting assembly is fixedly installed on the two side walls of the U-shaped base. A support assembly is provided inside the sealing assembly. A second limiting assembly is provided inside the heat exchange plates. A movable plate and a fixed plate are respectively provided inside the U-shaped base. The two ends of the movable plate are slidably connected to the guide rails, and the fixed plate is fixedly installed between the U-shaped bases.
[0005] The sealing assembly includes a sealing gasket. Sealing grooves are provided inside the side walls at both ends of the heat exchange plate. The sealing gasket is sealed and connected to the inside of the sealing groove. Connecting blocks are fixedly installed on the upper and lower side walls of the heat exchange plate. U-shaped frames are fixedly installed on the upper and lower ends of the sealing gasket. The U-shaped frames and connecting blocks are slidably connected to the guide rail.
[0006] Preferably, the support assembly includes a support rod, the sealing gasket has an internal mounting groove, the support rod is fixedly installed inside the mounting groove, and the sidewalls inside the mounting groove are tightly fitted to the sidewalls of the support rod.
[0007] Preferably, the first limiting component includes a sliding rod, which is symmetrically arranged inside the left side wall of the U-shaped seat. The U-shaped frame and the connecting block are symmetrically provided with sliding holes, which are slidably sleeved on the outside of the sliding rod.
[0008] Preferably, the second limiting component includes a slot, and the two end sidewalls of the U-shaped frame are slidably connected to the inside of the slot, and the slot is connected to the inside of the sealing groove.
[0009] Preferably, the positions of the U-shaped frame and the sliding holes in the connecting block correspond to each other, and the central axes of the corresponding sliding holes are all on the same axis.
[0010] Preferably, the sealing gaskets are respectively disposed between two adjacent heat exchange plates, and simultaneously sealed to the inside of the sealing grooves of the heat exchange plates on both sides.
[0011] Preferably, the end sidewalls of the U-shaped frame and the connecting block are both horizontal.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The sealing gasket and the sealing groove of this utility model can be disassembled, and the sealing gasket and the heat exchange plate are slidably connected between the guide rails. After the sealing gasket and the seal are disassembled, the sealing gasket will not be dislodged, which facilitates the comprehensive cleaning of the sealing gasket.
[0014] 2. In use, the sealing gasket has a support rod fixedly installed inside. The support rod can strengthen the hardness of the sealing gasket, so that after the sealing gasket is separated from the sealing groove, the positions of the sealing gasket and the sealing groove can still correspond to each other, making it convenient to install the sealing gasket and the sealing groove after the cleaning work is completed.

Detailed Implementation
[0020] 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.
[0021] Reference Figure 1 - Figure 4 This utility model discloses a leak-proof heat exchanger, comprising a U-shaped base 1. Guide rails 9 are fixedly installed on the upper and lower side walls of the U-shaped base 1. Multiple heat exchange plates 4 are fixedly installed at equal intervals between the two guide rails 9. A sealing assembly 6 is sealed and connected inside the heat exchange plates 4. A first limiting assembly 5 is fixedly installed on the two side walls of the U-shaped base 1. A support assembly 7 is provided inside the sealing assembly 6. A second limiting assembly 8 is provided inside the heat exchange plates 4. A movable plate 2 and a fixed plate 3 are respectively provided inside the U-shaped base 1. The two ends of the movable plate 2 are slidably connected to the guide rails 9, and the fixed plate 3 is fixedly installed between the U-shaped bases 1.
[0022] The sealing assembly 6 includes a sealing gasket 62. Sealing grooves 61 are provided inside the side walls at both ends of the heat exchange plate 4. The sealing gasket 62 is respectively sealed and connected to the inside of the sealing grooves 61. Connecting blocks 11 are fixedly installed on the upper and lower side walls of the heat exchange plate 4. U-shaped brackets 10 are fixedly installed on the upper and lower ends of the sealing gasket 62. The U-shaped brackets 10 and connecting blocks 11 are slidably connected to the guide rails 9. It should be noted that when the sealing gasket 62 is separated from the heat exchange plate 4, the sealing gasket 62 is positioned between the U-shaped seats 1, preventing it from falling off and facilitating subsequent cleaning and installation.
[0023] The support assembly 7 includes a support rod 72, and the sealing gasket 62 has an installation groove 71 inside. The support rod 72 is fixedly installed inside the installation groove 71, and the side walls inside the installation groove 71 are all tightly fitted with the side walls of the support rod 72; this ensures that the sealing gasket 62 is stable when it is separated from the sealing groove 61.
[0024] The first limiting component 5 includes a slide rod 51, which is symmetrically arranged inside the left side wall of the U-shaped seat 1. The U-shaped frame 10 and the connecting block 11 are symmetrically provided with sliding holes 52, which are slidably sleeved on the outside of the slide rod 51. This allows for convenient positioning of the heat exchange plate 4 and the sealing gasket 62, ensuring that the position of the sealing gasket 62 always corresponds to the position of the sealing groove 61.
[0025] The second limiting component 8 includes a slot 81, and the two end sidewalls of the U-shaped frame 10 are slidably connected to the inside of the slot 81, and the slot 81 is connected to the inside of the sealing groove 61; the U-shaped frame 10 can effectively support the position of the sealing gasket 62.
[0026] The positions of the U-shaped frame 10 and the sliding holes 52 in the connecting block 11 are all corresponding to each other, and the central axes of the corresponding sliding holes 52 are all on the same axis; this can enhance the stability of the positions of the sealing gasket 62 and the sealing groove 61.
[0027] The sealing gaskets 62 are respectively disposed between two adjacent heat exchange plates 4, and simultaneously sealed and connected to the inside of the sealing grooves 61 of the heat exchange plates 4 on both sides. It should be noted that one sealing gasket 62 needs to seal between two adjacent heat exchange plates 4 at the same time, which can effectively enhance the sealing performance inside the heat exchanger body.
[0028] The end sidewalls of the U-shaped frame 10 and the connecting block 11 are both horizontal. It should be noted that the horizontal end sidewalls of the U-shaped frame 10 and the connecting block 11 ensure that the corresponding horizontal positions of the heat exchange plate 4 and the sealing gasket 62 do not change after separation, thus improving the efficiency of subsequent installation.
[0029] The working principle of this utility model is as follows: When cleaning the heat exchange plate 4, first loosen the position of the moving plate 2 and move it to the left side wall, so that the heat exchange plate 4 slides on the guide rail 9, causing the sealing gasket 62 to separate from the heat exchange plate 4. At this time, due to the support of the support rod 72, the sealing gasket 62 can be stably positioned between the U-shaped seats 1.
[0030] Next, the surface of the heat exchange plate 4 and the sealing groove 61 are cleaned to remove impurities and dirt. The sidewalls of the sealing gasket 62 are also cleaned to ensure no residual impurities remain on its surface. After cleaning, the sealing gasket 62 is reinstalled into the sealing groove 61. The support rod 72 helps the sealing gasket 62 to be quickly positioned, ensuring precise alignment with the sealing groove 61.
[0031] Finally, the entire cleaning and assembly process is completed. These steps effectively prevent reduced sealing performance caused by damage to the gasket 62 or the accumulation of impurities, thereby improving the overall performance and service life of the heat exchanger.
[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
