Abstract
The invention discloses a five-chamber double-layer parallel flow evaporator and a heat exchanging method of the five-chamber double-layer parallel flow evaporator. The five-chamber double-layer parallel flow evaporator comprises a front row heat exchanging module, a rear row heat exchanging module, fins, a left side plate and a right side plate. The front row heat exchanging module and the rear row heat exchanging module are arranged in parallel and in a front and back mode. A freezing medium enters the rear row heat exchanging module from the front row heat exchanging module through overflowing holes in a collecting pipe on the front row heat exchanging module and overflowing holes in a collecting pipe on the rear row heat exchanging module. According to the five-chamber double-layer parallel flow evaporator, the evaporator is divided into five heat exchanging chambers and the five heat exchanging chambers are connected from front to back through three collecting pipe separating plates, wherein a fifth heat exchanging chamber is a heat exchange capability buffer zone of the whole evaporator. The flow direction of the freezing medium in each rear row heat exchanging flat pipe is automatically regulated according to change of a work environment of the evaporator. The five-chamber double-layer parallel flow evaporator is simple in structure and convenient to machine, is provided with the environmental adaptation buffer zone and improves heat exchange efficiency of a heat exchanger and adaptive capacity of application environment.
