Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger equipment, and particularly to a preparation device and a use method of a spiral plate heat exchanger. Background Art

[0002] The spiral plate heat exchanger is formed by rolling plates, forming two uniform spiral channels. Two heat transfer media can flow in full countercurrent, greatly enhancing the heat exchange effect. Even for two media with a small temperature difference, an ideal heat exchange effect can be achieved. In the existing spiral plate heat exchanger, riveting points are welded on the plates. After winding, due to the support of the riveting points, voids are formed, and the voids can realize the process of circulating heat exchange.

[0003] The existing equipment for the production and preparation of spiral plate heat exchangers has the following problems: For example, the invention patent with the publication number CN101749972A discloses a spiral plate heat exchanger and its production method. It includes a spiral body composed of two spiral plates (steel plates), forming two uniform spiral channels, namely a refrigerant channel and a heat medium channel. There is a partition plate in the middle of the spiral body. The two sides of the partition plate are respectively welded and sealed with the inner ends of the two spiral plates to separate the refrigerant channel from the heat medium channel. The refrigerant channel has a refrigerant medium inlet and a refrigerant medium outlet, and the heat medium channel has a heat medium inlet and a heat medium outlet. There is a bracket below the spiral body. Different from the prior art, the upper and lower edges of the two spiral plates (steel plates) forming the spiral body are bent from the inside to the outside, and the bent part is the spiral plate overlap. The spiral plate overlap is overlapped on the end face of the adjacent spiral plate and welded and sealed. The production equipment of this spiral plate heat exchanger realizes the structural design of multiple channels, and there is only one weld seam below each channel. However, the processing procedures implemented by this method are complex. Due to the design of multiple channels, the procedures are cumbersome during preparation, and it is impossible to quickly and efficiently wind and weld a single plate into a heat exchanger. The prior art is not easy to solve such problems. Therefore, a preparation device and a use method of a spiral plate heat exchanger are needed to solve the above problems. Summary of the Invention
