Problems solved by technology
[0003] However, due to factors such as structural design and thermal expansion and contraction of materials during the welding process, the heat exchanger is deformed. Since the heat exchanger needs to be installed in the box together with other accessories, the volume of the box is fixed and limited. The installation accuracy of the heat exchanger is very high, so the deformation of the heat exchanger will seriously affect the subsequent processing and installation of the heat exchanger, making the installation size out of tolerance, resulting in difficulty in installation
At the same time, in the process of processing, after the heat exchanger is assembled and before entering the brazing furnace for welding, the heat exchange tubes and fins are fixed with strapping straps and binding rods. The device is easily deformed
After the welding is completed, the strapping cannot be reused, resulting in waste of materials
Moreover, during the handling process before welding, the heat exchanger is easily deformed and damaged

The embodiment of the invention provides a heat exchanger holding device, comprising a bracket, a first vertical holding block, a second vertical holding block, first transverse holding blocks and second transverse holding blocks, wherein the first vertical holding block and the second vertical holding block are respectively arranged at the two vertical ends of the bracket; at least one of the first vertical holding block and the second vertical holding block can move vertically; the first transverse holding blocks and the second transverse holding blocks are respectively arranged at the two transverse sides of the bracket; and at least the first transverse holding blocks or the second transverse holding blocks can move transversely. The device can reduce deformation of the heat exchanger in the process of welding, effectively protect the heat exchanger from deformation and damage in the process of transport, improve the manufacturing precision of the heat exchanger, reduce the use of strapping materials and lower the manufacturing cost of the heat exchanger.
Description
technical field [0001] The invention relates to the technical field of heat exchanger manufacturing, in particular to a heat exchanger clamping device. Background technique [0002] A typical traditional heat exchanger includes a pair of headers parallel to each other and spaced apart from each other, heat exchange tubes at both ends respectively communicated with the inner chambers of the two headers, and heat exchange tubes arranged between adjacent heat exchange tubes Fins, and two side plates fixedly connected to the two outermost heat exchange tubes through the fins. In the manufacturing process, first insert the two ends of the heat exchange tubes into the holes of the header respectively, then place the fins between the adjacent heat exchange tubes, then place the binding rods on the outside of the two side plates, and use the binding tape (steel wire or steel belt) to bind and fix the heat exchanger along the height direction, and finally prevent the heat exchanger ...
