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 convenient for positioning and installation. Background Technique

[0002] A plate-fin heat exchanger generally consists of partition plates, fins, seals, and flow guiding plates. Fins, flow guiding plates, and seals are placed between two adjacent partition plates to form a sandwich layer, which is called a channel. Such sandwich layers are stacked according to different fluid flow modes and brazed into a whole to form a plate bundle, which is the core of the plate-fin heat exchanger.

[0003] However, in the prior art, the existing frame for installing the heat exchanger cannot be adjusted according to the size of the heat exchanger. Therefore, when replacing a heat exchanger with a larger size, it cannot be installed and fixed, which is not conducive to practical applications. In view of the above problems, we have developed a plate-fin heat exchanger convenient for positioning and installation. Content of the Utility Model

A connecting block is rotatably connected between the tops of the two first connecting rods. One side of the connecting block is fixedly connected to the second fixing block.

[0009] By setting, rotating the first double-headed screw can drive the first threaded block to move, and then the connecting block can be driven by the first connecting rod to make the second fixed block move up and down.

[0010] In a preferred embodiment, first fixing plates are fixedly connected to the outer sides of the mounting plates, and two first fixing holes are formed in the outer sides of the first fixing plates.

[0011] By setting, the heat exchanger can be fixed through the first fixing holes of the first fixing plates.

[0017] By setting, rotating the second bolt can drive the second double-headed screw to rotate.

[0018] The plate-fin heat exchanger provided by the present utility model that is convenient for positioning and installation has the following advantages:

[0019] First, when it is necessary to replace a heat exchanger with a larger size, when the original fixed points cannot stably support it, rotate the second double-headed screw.
