Heat exchanger with unfreezing function

The invention relates to the technical field of heat exchangers, and discloses a heat exchanger with an unfreezing function, which comprises a device body, fixing blocks are fastened on the front side and the rear side of the device body, a cavity is formed in the rear side of each fixing block, two groups of placing boxes are slidably connected in each cavity, and electric heating pipes are arranged in the placing boxes. A supporting plate is fastened to the inner wall of each cavity, first springs are fastened between the placing boxes and the supporting plates, and two-side sliding cavities are formed in the front sides of the cavities. According to the heat exchanger with the unfreezing function, the device body can be heated by arranging an electric heating pipe, and through cooperation between a movable plate and a fixed column, after a convex block is jacked by a jacking block to move, the movable plate drives the electric heating pipe to move in a manner of driving the fixed column to move; therefore,
