Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] Refer below Figure 1-Figure 5 A bent heat exchanger 10 according to an embodiment of the present invention is described. Such as Figure 1-Figure 5 As shown, the bent heat exchanger 10 according to the embodiment of the present invention includes a first header 101 , a second header 102 , fins 104 and a plurality of flat tubes 103 .

[0027] Each of the first header 101 and the second header 102 has at least one bent section 1011 and a straight section 1012 adjacent to the bent section 1011 . The bent section 1011 of the first header 101 corresponds to the bent section 1011 of the second header 102 . Both ends of the flat tube 103 are respectively connected to the first header 101 and the sec...

Abstract

The invention discloses a bending type heat exchanger. The bending type heat exchanger comprises a first collecting main, a second collecting main, a plurality of flat pipes and fins, wherein the two ends of each flat pipe are connected with the first collecting main and the second collecting main respectively, and the flat pipes are arranged at intervals in the axial direction of the first collecting main and the second collecting main; each fin is arranged between two corresponding adjacent flat pipes, each fin extends in a ripple shape in the length direction of the corresponding flat pipe, the thickness of each fin is FT, the bigger one of the external diameter of the first collecting main and the external diameter of the second collecting main is OD, the bigger one of the wall thickness of the first collecting main and the wall thickness of the second collecting main is T, the width of each flat pipe is W, the circular arc radius of each fin is FR, the height of each fin is FH, and 0.01<=(100*FT*FR*T) / (FH*OD)<=9. The bending type heat exchanger has the advantages of being reasonable and stable in structure, high in heat exchange efficiency, good in heat exchange performance, high in reliability, convenient to install and apply, good in water discharging performance and the like.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a bent parallel flow heat exchanger. Background technique [0002] Heat exchangers, such as parallel flow heat exchangers (such as multi-channel heat exchangers), are widely used in refrigeration systems. In some applications, it is necessary to bend the heat exchanger, that is, to bend the header of the heat exchanger . However, when the heat exchanger is bent along the length of the header, if it is bent improperly, it will have an adverse effect on the heat exchange performance of the heat exchanger, or it cannot meet the application requirements. Improvement needs. Contents of the invention [0003] This application was made based on the inventor's discovery of the following facts and problems: [0004] When bending the heat exchanger along the length direction of the header, if the bending radius is too large, the installation space of the heat exchanger cannot meet the application r...
