Modular heat exchanger for screw machine

The utility model discloses a modular heat exchanger for a screw machine. The modular heat exchanger comprises a hot fluid inlet module, a hot fluid outlet module and a spliced module, wherein a main body of the spliced module is rectangular, one side of the spliced module is provided with a triangular buffer, the hot fluid inlet module and the hot fluid outlet module are abutted, and the spliced module is positioned in between the hot fluid inlet module and the hot fluid outlet module; the spliced module is made of a brass material; an elongate fixed frame is arranged on the left sides of the hot fluid inlet module and the hot fluid outlet module and is simultaneously and sequentially connected with the hot fluid inlet module and the hot fluid outlet module. The modular heat exchanger has the beneficial effects that due to the design of the spliced module, a fluid return loop is prolonged, the heat exchange area is improved, certain blind area can be avoided, the utilization rate of equipment is higher, and
