Anti-freezing device for condenser

The utility model discloses an anti-freezing device for a condenser. The device comprises a bracket mechanism, a cooling box body, a heat exchange roller and a power mechanism, the support mechanism comprises an outer frame. The outer frame is of a cuboid frame structure. X-shaped supports are fixedly connected to the interiors of the two side walls of the outer frame. Connecting shaft pipes are movably connected into the X-shaped supports on the two sides of the support mechanism through bearings, a heat exchange roller located in the support mechanism is fixedly communicated between the twoconnecting shaft pipes, and the heat exchange roller is sleeved with a cooling box movably connected with the two connecting shaft pipes. According to the utility model, the speed reducing motor drives the heat exchange roller to rotate in the cooling box body, so that the outer surface of the heat exchange roller can be in uniform contact with cooling water in the cooling box body, and the heat exchange effect is remarka
