Abstract

The invention discloses a bending type heat exchanger which comprises a first collecting pipe, a second collecting pipe, a plurality of flat pipes and corrugated fins, wherein two ends of each flat pipe are connected with the first collecting pipe and the second collecting pipe, each flat pipe comprises a first section, a second section and a bending section positioned between the first section and the second section, the bending section is twisted around the length direction of the flat pipe relative to the first section and the second section to form a predetermined torsion angle, the flat pipe is bent at the bending section to form a predetermined included angle between the first section and the second section, the first section and the second section are obliquely arranged relative to the horizontal direction, and the bending sections of the flat pipes are aligned in the vertical direction to form funnel vortexes; and the corrugated fins are arranged between the first sections of the adjacent flat pipes as well as between the second sections of the adjacent flat pipes respectively. The bending type heat exchanger provided by the embodiment of the invention is good in heat exchange effect and draining effect.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a bent heat exchanger used as an evaporator. Background technique [0002] When the existing parallel flow heat exchanger is used as a condenser, the flat tubes are placed horizontally, but when used as an evaporator, the flat tubes need to be placed vertically to enhance drainage performance. However, the heat transfer performance of this type of evaporator is affected in some application environments. Contents of the invention [0003] The present application is based on the inventor's recognition of the following problems and the fact that the application of the evaporator with flat tubes placed vertically is limited by the size of the heat exchanger, and the heat transfer performance is affected. For example, when the evaporator is required to have a large length and a small height, for example, the space for installing the evaporator is a rectangular space with a large horizontal dimen...
