Technical Field
[0001] This utility model relates to the field of heat exchanger technology, specifically a multi-sealed heat exchanger. Background Technology
[0002] A plate heat exchanger is a high-efficiency heat exchanger composed of a series of corrugated metal plates stacked together. Thin rectangular channels are formed between the plates, through which heat exchange occurs. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss conditions, their heat transfer coefficient is 3-5 times higher than that of a tubular heat exchanger, their footprint is one-third that of a tubular heat exchanger, and their heat recovery rate can reach over 90%.
[0003] The sealing method between multiple plates in existing plate heat exchangers is relatively simple. Therefore, leakage of vapor or liquid may occur in the heat exchanger during use. At the same time, the sealing structure on existing plate heat exchangers is not stable enough and is prone to displacement due to impact. Due to the above two problems, the heat recovery rate of the heat exchanger decreases and its service life is affected. Utility Model Content

Furthermore, a first sealing gasket, a second sealing gasket, and a third sealing gasket are provided inside the plate assembly. The cooperation between the second and third sealing gaskets prevents steam or liquid from leaking from the connection between multiple plates and connecting parts inside the heat exchanger. The third sealing gasket also acts as a limiter, preventing the second sealing gasket from shifting due to impact. At the same time, the first sealing gasket further reduces the amount of steam or liquid leakage inside the heat exchanger, thereby improving the service life of the heat exchanger.

[0010] By adopting the above technical solution, the connecting component is stably and securely installed on the plate through the round hole, and the connecting component can play a guiding role, which can prevent gas or liquid from directly impacting the second sealing gasket when entering between the two plates.
[0011] Preferably, the two sides of the plate are connected to the second sealing gasket through a connecting member, and the top of one end and the bottom of the other end of the plate are connected to the third sealing gasket through a connecting member.

Furthermore, the cooperation between the third sealing gasket and the connecting piece prevents the second sealing gasket from shifting due to impact, thereby improving the service life of the heat exchanger.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-7This utility model provides an embodiment of a multi-sealed heat exchanger, comprising: a movable plate 1, a sealing sleeve 2 on one side of the movable plate 1, a plate assembly 3 inside the sealing sleeve 2, a fixing clamp 4 on one side of the plate assembly 3, and bushings 5 at the four corners of one side of the fixing clamp 4; the plate assembly 3, which is composed of multiple plates 31 stacked together, with a first sealing gasket 32, a connecting member 33, a second sealing gasket 34, and a third sealing gasket 35 on both sides of each plate 31; and a sealing sleeve 2 on the outer surface of the plate assembly 3, which seals the connections between the multiple plates 31 on the plate assembly 3. The covering not only protects the plate assembly 3, but also reduces the amount of steam or liquid leakage inside the heat exchanger. Furthermore, the plate assembly 3 is equipped with a first sealing gasket 32, a second sealing gasket 34, and a third sealing gasket 35. The cooperation between the second sealing gasket 34 and the third sealing gasket 35 prevents steam or liquid leakage from the connection points between the multiple plates 31 and the connecting member 33. The third sealing gasket 35 also acts as a limiter, preventing the second sealing gasket 34 from shifting due to impact. Simultaneously, the first sealing gasket 32 further reduces the amount of steam or liquid leakage inside the heat exchanger, thereby improving the service life of the heat exchanger.
[0030] In this embodiment, grooves are provided on both sides of the plate 31, and a first sealing gasket 32 is provided on the inner wall of the groove on the plate 31. The first sealing gasket 32 can be stably and firmly set on the plate 31 through the groove, and the first sealing gasket 32 can be tightly attached to the side wall of the plate 31, so that the first sealing gasket 32 is not easy to shift when multiple plates 31 are stacked.
[0031] In this embodiment, round holes are provided at the four top corners on one side of the plate 31. The size of the round holes on the plate 31 is adapted to the size of the connecting member 33. The plate 31 is connected to the connecting member 33 through the round holes. The connecting member 33 is stably and firmly installed on the plate 31 through the round holes. The connecting member 33 can play a guiding role and can prevent vapor or liquid from directly impacting the second sealing gasket 34 when entering between the two plates 31.
[0032] In this embodiment, the two sides of the plate 31 are connected to the second sealing gasket 34 through the connecting member 33. The top of one end and the bottom of the other end of the plate 31 are connected to the third sealing gasket 35 through the connecting member 33. The second sealing gasket 34 can be installed with the assistance of the connecting member 33, and the connecting member 33 can prevent the second sealing gasket 34 from shifting. At the same time, the third sealing gasket 35 can be stably and firmly installed on the plate 31 through the connecting member 33.
[0033] In this embodiment, the second sealing gasket 34 abuts against the third sealing gasket 35, and the sealing sleeve 2 is sleeved with the plate assembly 3. Because the second sealing gasket 34 and the third sealing gasket 35 abut against each other, the second sealing gasket 34 is prevented from shifting when it is subjected to impact.
[0034] In this embodiment, the bushing 5 is connected to the connecting member 33, the sealing sleeve 2 is made of rubber, and the middle positions of both ends of the movable plate 1, the sealing sleeve 2 and the plate group 3 are provided with fixing ports. The two ends of one side of the fixing clamp 4 are provided with fixing holes. By setting a fixing structure at the fixing port, the movable plate 1, the sealing sleeve 2, the plate group 3 and the fixing clamp 4 are fixed, so that the sealing sleeve 2 can be tightly attached to the outer surface of the plate group 3.
[0035] In this embodiment, the movable plate 1 and the fixed clamping plate 4 are provided with multiple openings at the top, bottom and both ends. The four top corners of one side of the fixed clamping plate 4 are provided with fixing holes. The fixed clamping plate 4 is connected to the bushing 5 through the fixing holes. The movable plate 1, the plate group 3 and the fixed clamping plate 4 are further fixed by setting a fastening structure at the opening. The bushing 5 is stably and firmly installed on the fixed clamping plate 4 through the fixing holes.
[0036] Working principle: After steam or liquid enters the heat exchanger, the cooperation between the second sealing gasket 34 and the third sealing gasket 35 prevents steam or liquid from leaking from the connection between the multiple plates 31 and the connecting member 33. Moreover, the third sealing gasket 35 can also play a limiting role, thereby preventing the second sealing gasket 34 from shifting due to impact. In addition, a sealing sleeve 2 is provided on the outer surface of the plate group 3, which covers the connection between the multiple plates 31 on the plate group 3. This not only protects the plate group 3, but also reduces the amount of steam or liquid leakage in the heat exchanger.
