Description

Technical Field

[0001] The utility model relates to the technical field of fin-type steam heat exchangers, in particular to a fin-type steam heat exchanger. Background Art

[0002] Finned steam heat exchanger is a highly efficient heat exchange device widely used in various heat exchange systems. It achieves the purpose of enhancing heat transfer by adding fins to ordinary base tubes. The presence of fins greatly increases the contact area between the fluid and the heat exchanger, thereby improving the heat exchange efficiency.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN215177071U discloses a fin-type heat exchanger, including a heat exchanger body and at least one group of suspension hooks, the suspension hooks are connected to the middle part of the heat exchanger, the heat exchanger body includes a base tube and a plurality of fins arranged at intervals along the base tube, the fins include a heat-conducting substrate and tube holes arranged on the heat-conducting substrate, the base tubes are passed through the tube holes of the fins, a plurality of groups of arc-shaped convex teeth are provided on the upper and lower sides of the heat-conducting substrate, and abutment portions protruding to one side are provided on the left and right sides of the heat-conducting substrate, and the abutment portions abut against the heat-conducting substrate of the adjacent fins.

[0004] The above-mentioned finned heat exchanger disperses the effect of gravity on the finned heat exchanger by adding a suspension hook, and provides abutment parts on the fins, and adjacent fins are closely connected through the abutment parts, thereby improving the overall structural strength of the finned heat exchanger, avoiding the finned heat exchanger from being deformed by heat in a high temperature environment and under the action of gravity, so that more fins can be added to improve the fin ratio and heat exchange effect; however, during the operation of the finned heat exchanger, if steam flows in the fin tube and exchanges heat with the external medium through the fins, this heat exchange process will cause the surface temperature of the fin to change. If the temperature of the fin surface is lower than the dew point temperature of the surrounding air, the water vapor in the air will condense on the surface of the fin to form water droplets. If the water droplets condensed on the fins are not handled in time, it may affect the heat exchange efficiency of the heat exchanger.

[0005] Therefore, the utility model provides a fin type steam heat exchanger to solve the above problems. Utility Model Content

Through the use of the guide plate, the water droplets condensed on the fin plate can drip into the liquid collecting box for collection and treatment, avoiding the influence of the water droplets on the heat exchange efficiency.

[0011] Preferably, in order to solve the problem of water droplets flowing along the guide plate, the guide plate is U-shaped, and the open end of the guide plate is located on the side close to the liquid collecting tank. By arranging an inverted U-shaped guide plate on the steam pipe, water droplets are prevented from dripping directly on the steam pipe, ensuring a smoother flow of water droplets.

Through the use of the gasket and the support column, the two adjacent fin plates are more secure when used, and the strength of use is improved.

[0017] (III) Beneficial effects

[0018] The fin-type steam heat exchanger has a simple structure and is easy to use. By arranging a liquid collecting box and support columns, a guide plate and obliquely arranged air guide holes, it can effectively prevent water droplets from interfering with air flow. At the same time, through the design of the guide groove and the surface of the fin plate, it can better guide the flow of water droplets and improve the heat exchange efficiency, ensuring that the water droplets enter the liquid collecting box smoothly, which is beneficial to the drainage and dryness of the fin plate.

A guide plate 21 is fixedly installed at a position of the steam pipe 2 between two adjacent fin plates 3. The guide plate 21 is U-shaped, and the open end of the guide plate 21 is located on a side close to the liquid collecting tank 4. A plurality of evenly distributed air guide holes 22 are symmetrically opened on the guide plate 21.

[0029] When in use, when the steam is conducted inside the bracket 1 through the steam pipe 2, the heat in the steam can be conducted to the fin plate 3, and the heat is taken away by the air flowing inside the fin plate 3. The water droplets that may condense during the heat exchange process can flow and drip along the fin plate 3 and the guide plate 21 and finally enter the collecting tank 4. When the air flows, it can pass through the air guide hole 22 to prevent the guide plate 21 from affecting the normal flow of air.

[0030] Specifically, one end of the air guide hole 22 close to the steam pipe 2 is at least higher than the other end; the air guide hole 22 is arranged obliquely to prevent water drops flowing along the guide plate 21 from entering the air guide hole 22 .

[0031] Furthermore, a plurality of guide grooves 31 distributed in a linear array are provided at both ends of the fin plate 3; the guide grooves 31 can increase the surface area of ​​the fin plate 3 and improve the heat exchange efficiency, and the water droplets can flow along the guide grooves 31, which can better process the water droplets.

[0032] Furthermore, gaskets 32 are fixedly installed at the corners of two adjacent fin plates 3, and support columns 33 are fixedly installed on the gaskets 32. The gaskets 32 and the support columns 33 are made of the same material as the fin plates 3; the gaskets 32 and the support columns 33 at the corners of the fin plates 3 can support the corners of the fin plates 3, so that the fin plates 3 are stronger when in use.

[0034] Different from Example 1, a drain outlet 41 is provided at the corner of the liquid collecting box 4 away from the bracket 1, and a guide groove 42 is symmetrically provided in the drain outlet 41.

[0035] When treating the water in the liquid collecting box 4, the liquid collecting box 4 can be pulled out of the bracket 1 through the guide rail 11, and then the slide plate 51 can be pressed to make the slide plate 51 slide along the guide groove 42 and lift the sealing plate 53 through the support rod 52, so that the sealing plate 53 moves out of the drain outlet 41. At this time, the water in the liquid collecting box 4 can be discharged along the drain outlet 41. After the treatment is completed, the slide plate 51 can be loosened and the sealing plate 53 can be reset under the action of the spring 54 for continued use.
