Heat exchanger clamping device

The invention belongs to the technical field of heat exchangers, and particularly relates to a heat exchanger clamping device which comprises a placing base. An anti-skid groove is formed in the top of the placement base; the top of the placing base is fixedly connected with a rotating bracket; a rotating shaft is rotationally connected to the central position of the rotating bracket; the end part of the rotating shaft is fixedly connected with a rotating disc; a fixed rod is connected to the rotating disc in a sliding manner; the end part of the fixed rod is rotationally connected with a rotating rod; a first positioning block is fixedly connected to the side wall of the fixing rod; a first positioning groove is formed in the position, corresponding to the first positioning block, in the rotating disc. According to the structural design that the adjusting assembly is driven to rotate through the rotating shaft, and then the clamping assembly is adjusted through the adjusting assembly, so that the heat exchan
