Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a detachable plate heat exchanger. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. The plate heat exchanger is an ideal device for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, wide application, long service life, etc.

[0003] The types of plate heat exchangers mainly include frame type (detachable type) and brazed type. When the traditional detachable plate heat exchanger is in use, the metal sheets are mostly limited and pressed by bolts, which is cumbersome to operate. Moreover, once the bolts are damaged, it is even more troublesome during disassembly and assembly. In view of the above problems, the inventor proposes a detachable plate heat exchanger to solve the above problems. Summary of the Utility Model

The number of the metal sheets is several, and several of the metal sheets are arranged in an array from left to right. Concave plates are fixedly connected to the upper and lower end faces of the metal sheet. The concave opening of the concave plate corresponds to and cooperates with the cross bar. The concave opening of the concave plate can cooperate with the cross bar. When installing the metal sheet, the metal sheet can be first in an inclined state so that the concave plates at the upper and lower ends correspond to the cross bar, and then the metal sheet is adjusted to complete the installation of the metal sheet.
