Description

Technical Field

[0001] This utility model relates to the field of coil heat exchanger technology, specifically a static discharge coil heat exchanger without internal welding. Background Technology

[0002] Heat exchangers are key equipment for heat transfer in the industrial field. Their core function is to transfer heat from high-temperature fluids to low-temperature fluids through solid walls or direct contact. They are widely used in industries such as chemical, petroleum, power, and food. However, existing heat exchangers often require welding the cooling coils to the equipment that needs heat exchange during installation to fix the cooling coils. This method is cumbersome and complicated, and it is also very inconvenient to replace the cooling coils later. Therefore, a heat exchanger with a static discharge coil without internal welding is provided. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a non-internal welded exhaust coil heat exchanger to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger with a non-internal welded exhaust coil, comprising an inner cylinder, a cooling coil sleeved inside the inner cylinder, one end of the cooling coil connected to a coil joint, one end of the coil joint connected to a welded joint B, a flange cover connected to the top of the inner cylinder, a connecting pipe B disposed on the top of the flange cover, a flange B welded to the top of the connecting pipe B, the other end of the cooling coil passing through the flange cover and connected to a connecting bend, one end of the connecting bend connected to a welded joint A, one end of the welded joint A connected to a connecting pipe A, and one end of the connecting pipe A connected to a flange A.

[0005] As a preferred embodiment of this utility model, the inner cylinder is welded to the flange cover.

[0006] In a preferred embodiment of this utility model, the connecting pipe B is welded to the flange cover, the flange cover is connected to the connecting pipe B, and the flange cover is connected to the inner cylinder.

[0007] As a preferred embodiment of this utility model, the connecting bend is welded to the ends of the welding joint A and the cooling coil, respectively.

[0008] In a preferred embodiment of this invention, the flange A is welded to the connecting pipe A.

[0009] As a preferred embodiment of this utility model, the coil connector is welded to the other end of the cooling coil, and the welded joint B is welded to the coil connector.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the cooling coil of the heat exchanger is directly sleeved on the outer wall of the inner cylinder, allowing the cooling coil to contact the outer wall of the inner cylinder for heat exchange, without the need for welding to the inner cylinder, which not only facilitates later replacement, but also saves installation time and cost. The cooling coil is fixed by welding joints at both ends, improving stability, and the inner cylinder also serves to limit the movement of the cooling coil. Attached Figure Description
