Description
Technical Field
[0001] The utility model relates to the technical field of plate-fin heat exchangers, in particular to a plate-fin heat exchanger with adjustable brackets. Background Art
[0002] The reasons for the adjustable brackets of plate-fin heat exchangers mainly involve multiple aspects such as the installation, maintenance, and performance optimization of heat exchangers. In plate-fin heat exchangers, the distance between fins is crucial for heat exchange efficiency. When ash cleaning is required, by adjusting the brackets to increase the fin spacing, a spacious ash cleaning space can be formed, facilitating the cleaning operation of the dust between the fins.
[0003] Chinese Patent with Patent Publication No. CN221123110U discloses an aluminum plate-fin heat exchanger with adjustable brackets. The solution can drive the movement of the connecting blocks on both sides by rotating the adjusting handle, thereby realizing the clamping and loosening of the slider. The reset spring can be used to quickly separate the fins of the heat exchanger, facilitating the cleaning of dust. The device has a simple structure and is easy to use. However, the closing and dispersion of the fins of the heat exchanger are carried out simultaneously, which results in the need to occupy a large amount of space. Consequently, the number of fins of the heat exchanger will decrease, and the heat exchange efficiency will be reduced. Moreover, the spring has instability, and its elasticity will gradually decline over time. If it needs to be replaced, the whole machine needs to be disassembled, which is rather cumbersome. Therefore, a plate-fin heat exchanger with adjustable brackets is proposed. Summary of the Invention
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a plate-fin heat exchanger with adjustable brackets.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A plate-fin heat exchanger with adjustable brackets includes a heat exchanger housing. Inside the heat exchanger housing, there are heat exchanger fins. Outside the heat exchanger fins, there are sliders. On the sliders, there are fixed blocks. The outside of the fixed blocks is connected with telescopic members. The telescopic members include a first adjusting plate and a second adjusting plate, which are rotatably connected between them. The outside of the fixed blocks is connected with positioning touch rods.
[0007] Preferably, a plurality of sliding rods are fixedly installed between the inner walls of the heat exchanger housing. The sliding rods are respectively installed on the upper and lower sides of the heat exchanger housing. Through holes are opened on the sliders, and the sliding rods pass through the through holes. The sliders are slidably connected to the outer surfaces of the sliding rods.
[0008] Preferably, a plurality of the sliders are provided, and are all slidably connected to the outer surfaces of the upper and lower slide rods. The sliders are correspondingly arranged up and down. A plurality of heat exchanger fins are provided and are all installed between the sliders. The heat exchanger fins are arranged horizontally between them.
[0009] Preferably, two fixing blocks are symmetrically installed on one side of the slider. An arc-shaped positioning groove is formed on the top surface of the fixing block. One end of the first adjusting plate is provided with a middle opening. One end of the second adjusting plate is connected to the middle opening. The first adjusting plate and the second adjusting plate are both rotatably connected to the outer surface of the fixing block. A plurality of the first adjusting plates and the second adjusting plates are provided and are all sequentially connected to the fixing block.
[0010] Preferably, a rotating shaft is provided at the other end of the first adjusting plate. The other end of the second adjusting plate is connected to the inside of the other end of the first adjusting plate. The rotating shaft is connected between the first adjusting plate and the second adjusting plate.
[0011] Preferably, a plurality of positioning cavities are formed in the heat exchanger housing. The positioning contact rod is connected in the positioning cavity. A detachable nut is threadedly connected to each positioning cavity. A spring is connected between the positioning contact rod and the detachable nut. One end of the positioning contact rod penetrates to the inside of the heat exchanger housing and is connected in the positioning groove.
[0012] Preferably, a positioning plate is also movably connected in the heat exchanger housing. The positioning plate is slidably connected to the slide rod. The positioning plate is connected to one side of the heat exchanger fin. A fixing frame is fixedly installed on the positioning plate. A positioning screw is provided on the fixing frame and is connected to the outer surface of the heat exchanger housing.
[0013] The beneficial effects of the present utility model are:
[0014] In this solution, the telescopic member can facilitate the individual movement between the heat exchanger fins, reducing the space required for cleaning. The positioning contact rod can facilitate the positioning of the position of the fixing block, facilitating the identification of whether it has moved to the designated position. The detachable nut can facilitate the replacement of the spring. The positioning plate can fix the position of the heat exchanger fin.
[0015] In this solution, during the cleaning process of the heat exchanger fins, the movement of the fins requires a large amount of equipment space, which is reduced. When replacing the spring, the possibility of disassembling the whole machine is reduced. The possibility of installing more fins in the same volume of the device is increased, thereby improving the heat exchange efficiency of the device and also improving the disassembly and replacement efficiency of some components in the device, avoiding excessive time consumption.
