Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically relating to an orifice plate structure in a heat exchanger. Background Technology

[0002] An orifice plate in a heat exchanger is a metal plate with regularly arranged holes. It is usually installed in the shell side or tube bundle area of ​​the heat exchanger to support the tube bundle, guide fluid flow, and optimize heat exchange efficiency. The tube bundle passes through the orifice plate, with one fluid flowing inside the tube bundle and another fluid flowing between the orifice plates. The two fluids exchange heat through the orifice plate. Existing orifice plates are all open structures, with the tube bundle passing through the orifice plate vertically. To improve heat exchange efficiency, a relatively dense parallel installation method of orifice plates is often adopted. This vertical tube bundle and vertical orifice plate installation method has the following disadvantages: (i) The contact area between the tube bundle and the orifice plate is small, resulting in a low efficiency of heat transfer from the tube bundle to the orifice plate. (ii) After the tube bundle and the orifice plate are installed and connected, disassembly is difficult. After long-term use, dust easily accumulates between the orifice plates, making cleaning difficult. Utility Model Content

[0010] Preferably, both the first fluid pipe clamp and the second fluid pipe clamp are configured as semi-circular.

[0011] The technical effects and advantages of this utility model are as follows: The orifice plate structure of this heat exchanger uses a combination of fluid tube clamp plate one and fluid tube clamp plate two to clamp the fluid tube, which makes the contact with the fluid tube more sufficient and improves the heat exchange effect; moreover, the adjacent heat dissipation plates are connected by the interconnection of the track plate and the slider, and the fluid tube is fixed without additional welding, which is very convenient; fluid tube clamp plate one and fluid tube clamp plate two are detachable and easy to clean, and the fluid tube is contained between fluid tube clamp plate one and fluid tube clamp plate two, and will not come into contact with the heat exchange medium flowing between the heat dissipation plates, so the fluid tube is not easy to be contaminated and the cleaning of the fluid tube can be reduced.
