Detachable spiral winding heat exchanger

The utility model relates to the technical field of heat exchangers, in particular to a detachable spiral winding heat exchanger which comprises a machine shell, the machine shell is divided into two halves with the side edge perpendicular to the center line, the machine shell is fixedly connected through bolt plates arranged on the upper side and the lower side, and through pipes are arranged at the left end and the right end of the machine shell. The front side of the machine shell is fixedly connected with a side frame, the upper side and the lower side of the machine shell are each provided with a discharge port assembly, the left end and the right end of the interior of the machine shell are each fixedly connected with a fixing support, and the fixing supports are connected with a heat exchange pipeline; compared with the prior art, under the condition that the same cooling water capacity is not changed, the heat exchange efficiency of the equipment is improved by increasing the flow speed of cooling wat
