Description

Technical Field

[0001] The utility model relates to the technical field of air guide covers, in particular to an air guide cover for a heat exchanger which is convenient to fix. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. The existing air guide covers for heat exchangers are not convenient to fix during use, and it is rather laborious and time-consuming to replace the ventilation plates. The patent document with the publication number CN215295982U discloses an air guide cover for a heat exchanger which is convenient to fix. It clamps the clamping plate in the clamping block, and drives the fixing pin to penetrate through the fixing holes of the clamping plate and the clamping block by the reaction force of the spring installed on the U-shaped plate, which is convenient for the fixation between the clamping plate and the clamping block, with simple operation, saving labor and effort, and being convenient for replacing the circular ventilation plate.

[0003] There are still some deficiencies in the above device during installation and use. Since the four clamping plates on the circumferential side of the circular ventilation plate correspond to the four clamping units on the second cover body, when installing and fixing, it is necessary to pull open the four pull rods and fixing pins at the same time before the circular ventilation plate can be installed and fixed, and the same is true during disassembly. Obviously, the relatively large number of clamping units is not conducive to the actual operation of the staff, and there is a certain irrationality in the structural setting and application, which brings inconvenience to the installation, fixation, disassembly and maintenance of the air guide cover. Therefore, an air guide cover for a heat exchanger which is convenient to fix is now proposed to solve the problems raised above. Summary of the Utility Model
