Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a clamping plate type finned tube heat exchanger. 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 one of the key devices for improving energy efficiency. The heat exchanger industry involves nearly 30 sectors, including HVAC, pressure vessels, wastewater treatment equipment, chemicals, and petroleum, forming interconnected industrial chains.

[0003] However, existing clamped plate finned tube heat exchangers have limited pressure-bearing capacity, requiring more investment to increase their pressure-bearing capacity. When used under air heating conditions, traditional finned tube heat exchangers have limited high-pressure resistance on the air side, resulting in insignificant benefits and poor applicability. Utility Model Content

[0004] The purpose of this invention is to provide a clamping plate type finned tube heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping plate type finned tube heat exchanger, comprising a tube bundle, an air inlet on one side of the tube bundle, an air outlet on the other side of the tube bundle, internal side plates on both the front and rear sides of the tube bundle, clamping plates on the outer sides of the internal side plates, clamping screws on the inner sides of the front and rear clamping plates, the front and rear clamping plates clamping the tube bundle by the clamping screws, the clamping screws penetrating the tube bundle, a sleeve being provided at the penetration point, a tube-side inlet being provided at one end of the tube bundle, finned tubes being provided inside the tube bundle, a tube sheet being provided inside the tube bundle, and lugs being provided on both the front and rear sides of the clamping plates.

[0006] Preferably, the diameter of the sleeve is larger than the diameter of the clamping screw.

[0007] Preferably, there are multiple ear seats, which are evenly distributed on the outer walls of the front and rear clamping plates.

[0008] Preferably, there are multiple clamping screws, which are evenly distributed on the inner sides of the front and rear clamping plates.

[0009] Preferably, the sleeve is welded to the front and rear side plates.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the clamping plate type finned tube heat exchanger has a compact structure, high pressure resistance, and low investment cost through the structure of air inlet, clamping plate, tube inlet, air outlet, clamping screw, finned tube, tube sheet and lugs. When used under air heater conditions, it solves the problem of insufficient high pressure resistance on the air side of traditional finned tube heat exchangers. Attached Figure Description
