Plate rolling heat exchange body, heat exchanger of modularly-assembled plate rolling heat exchange body and heat exchange method

Abstract

The invention discloses a plate rolling heat exchange body, a heat exchanger of the modularly-assembled plate rolling heat exchange body and a heat exchange method and belongs to the technical field of heat exchangers. The heat exchanger comprises flowing medium inlets, flowing medium outlets, the plate rolling heat exchange body, an intermediate partitioning plate and a heat exchanger shell body. The intermediate partitioning plate is arranged inside the heat exchanger shell body. A plurality of installing holes are formed in the intermediate partitioning plate. The plate rolling heat exchange body is inserted into the mounting holes. The flowing medium inlets communicate with a first transverse plate through hole and a second transverse plate through hole. The flowing medium outlets communicate with through holes in the two sides of the plate rolling heat exchange body. The plate rolling heat exchange body is formed by the step that a flat plate is folded in the position one half of the flat plate and then rolled in the same direction, and an annular track m and an annular track n are formed inside the plate rolling heat exchange body. The heat exchange bodies composing one of heat exchanger structures all adopt plate rolling heat exchange body structures, so that arbitrary combination and installing can be conducted according to installing spaces and occasions, processing is simple, and installing and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, more specifically, to a coiled plate heat exchange body, a heat exchanger for modularly assembling a coiled plate heat exchange body, and a heat exchange method. Background technique [0002] Due to environmental pollution problems, traditional electric heating, boilers and other low-efficiency and heavily polluting hot water devices will be gradually discontinued and replaced by high-efficiency heat pump hot water devices. At present, heat exchangers used in heat pump water heating devices are mainly divided into two types: casing type and plate type. For example, the heat exchange body of the current coaxial body combined heat exchanger is mainly composed of steel pipes. Practice has proved that although a heat exchanger composed of multiple steel pipe heat exchangers has high heat exchanger efficiency and pressure bearing capacity, its application is limited by the size of the steel p...

Problems solved by technology

However, in this application, the first heat exchanger unit and the second heat exchanger unit are connected through joint pipe fittings and external connecting pipes, and the flow resistance of fluid passing through the joint pipe fittings and external connecting pipes is relatively large. This problem has not been paid enough attention ; and the overall structure of the application is relatively complex, the processing and manufacturing costs are high, and the practicability needs to be enhanced
