Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger sealing technology, specifically a high-performance heat exchanger sealing strip. Background Technology
[0002] A heat exchanger is an energy-saving device that facilitates heat transfer between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, bringing the fluid temperature to the specified parameters to meet process requirements. It is also a key component for improving energy efficiency. Plate-fin heat exchangers are a type of heat exchanger that typically consists of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between adjacent baffles to form a sandwich layer, called a channel. These sandwich layers are stacked according to different fluid flow patterns and brazed together to form a plate bundle. The plate bundle is the core of the plate-fin heat exchanger. The advent of plate-fin heat exchangers has significantly improved heat exchange efficiency. They also offer advantages such as small size, light weight, and the ability to handle two or more media. Currently, plate-fin heat exchangers are widely used in industries such as petroleum, chemical, and natural gas processing.
[0003] Existing heat exchanger seals are prone to deformation during use, resulting in gaps between the seal and the heat exchanger. To address this, this application proposes a high-performance heat exchanger seal. Utility Model Content
[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0005] In view of the problems existing in the above and / or existing high-performance heat exchanger seals, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a high-performance heat exchanger seal. The outer sealing plate is closed outside the connection gap. The elastic plate is deformed under pressure, squeezing the internal air cylinder. The gas in the air cylinder enters the air bag through the air pipe, causing the air bag to expand and effectively seal the gap between the outer sealing plate and the heat exchanger, improving the sealing effect and preventing leakage.
[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0016] As a preferred embodiment of the high-performance heat exchanger seal described in this utility model, the outer edges of the outer sealing plate are all set to be arc-shaped.
[0017] Compared with the prior art, the outer sealing plate of this utility model is connected to the gap of the heat exchanger by an elastic clamp. After connection, the outer sealing plate is sealed outside the connection gap. The elastic clamp is deformed under pressure, squeezing the internal air cylinder. The gas in the air cylinder enters the air bag through the air pipe, causing the air bag to expand and effectively seal the gap between the outer sealing plate and the heat exchanger, improving the sealing effect and preventing leakage.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0027] This utility model provides a high-performance heat exchanger seal. An outer sealing plate encloses the joint gap. An elastic clamp deforms under pressure, compressing the internal air cylinder. Gas from the air cylinder enters the air bladder through an air pipe, causing the air bladder to expand and effectively seal the gap between the outer sealing plate and the heat exchanger, improving the sealing effect and preventing leakage. (See also...) Figures 1-3 It includes: a sealing component 100 and an expansion component 200.
[0028] The sealing component 100 includes an outer sealing plate 110, a sealing gasket 120, and an elastic retaining plate 130. The sealing gasket 120 is provided on the side wall of the outer sealing plate 110, and the elastic retaining plate 130 is provided on all four sides of the side wall of the outer sealing plate 110.
[0029] Among them, the elastic plate 130 adopts a Z-shaped bending plate. The elastic plate 130 is in an outward expansion state in its natural state. During installation, the elastic plate 130 is embedded in the gap of the heat exchanger, so that the outer sealing plate 110 covers the outside of the gap of the heat exchanger and seals the gap. At the same time, the sealing gasket 120 is attached to the gap to improve the sealing effect.
[0030] The expansion component 200 is disposed on the outer side wall of the outer sealing plate 110. The expansion component 200 includes an airbag 210, an air tube 220 and an air cylinder 230. The airbag 210 is fixed on the outer side wall of the outer sealing plate 110. The airbag 210 is connected to the air cylinder 230 through the air tube 220. The air cylinder 230 is disposed between the elastic clamping plates 130 on the left and right sides.
[0031] The air cylinder 230 has screw holes at both ends, and the elastic plate 130 has bolts connected to the screw holes for screwing and fixing. When the sealing component 100 is installed, the elastic plate 130 squeezes the air cylinder 230 to inflate the air bag 210, and the inflated air bag 210 effectively seals the gap between the outer sealing plate 110 and the heat exchanger.
[0032] Because the heat exchanger operates at high temperatures, the gasket 120, air bag 210, air pipe 220, and air cylinder 230 are all made of high-temperature resistant components to improve their service life.
[0033] Because of the presence of pipes, in order to avoid structural interference and gaps, a pipe channel is provided inside the sealing gasket 120, through which the gas pipe 220 passes, to prevent exposed pipes from getting stuck between the outer sealing plate 110 and the heat exchanger and affecting the sealing effect.
[0034] To prevent wind-induced cuts to workers, the outer edges of the outer sealing plate 110 are all curved.
[0035] In practical use, the elastic clamp 130 is embedded in the gap of the heat exchanger, so that the outer sealing plate 110 covers the outside of the gap of the heat exchanger and seals the gap. At the same time, the sealing gasket 120 is attached to the gap. When the sealing component 100 is installed, the elastic clamp 130 squeezes the air cylinder 230 to inflate the air bag 210. The inflated air bag 210 effectively seals the gap between the outer sealing plate 110 and the heat exchanger, improving the sealing effect.
[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
