A heat exchanger includes a flat tube and a plurality of fins. The plurality of fins are arranged on the flat tube and inclined with respect to a longitudinal direction of a cross section perpendicular to an axis of the flat tube. The plurality of fins may be inclined at different angles with respect to the axis of the flat tube. The flat tube may include a straight portion on which the plurality of fins are arranged, and a bend on which at least one fin other than the plurality of fins is arranged. The at least one fin extends perpendicularly to the axis of the flat tube.

A double-row bent heat exchanger is provided. The heat exchanger includes: a first header and a second header; flat tubes each divided into a first straight segment connected to the first header, a second straight segment connected to the second header and a twisted segment connected between the first straight segment and the second straight segment, along a length direction of the flat tube; and fins disposed between adjacent first straight segments and between adjacent second straight segments. The flat tube is bent at the twisted segment around a first bending axis (L) to provide a first bending portion. The first header and the second header are bent around at least one second bending axis (K) to provide at least one second bending portion.

A component can be formed having an integral monolithic body. The integral monolithic body can be formed utilizing electroforming processes such as electrodeposition of metal alloys. The electroformed monolithic body can be formed utilizing multiple anodes powered by multiple power sources. The monolithic body can have differing local material properties determined during formation of the component.

The present invention discloses a method for preparing an evaporator for reducing water condensing capacity and an evaporator. The preparation method comprises steps of: step A: selecting fins; step B: stacking; step C: arranging tubes; and, step D: expanding tubes. In accordance with the present invention, the existing fins and devices can be used to produce an evaporator in which the distance between two adjacent fins satisfies the requirements of the freezing operation, ensuring the normal operation of an air conditioner when the refrigeration temperature is below 0° C.

A vapor chamber structure includes a thermally conductive housing, a capillary structure layer, a grid structure layer, and a working fluid. The thermally conductive housing has a sealed chamber, where a pressure in the sealed chamber is lower than a standard atmospheric pressure. The capillary structure layer is disposed in the sealed chamber. The grid structure layer is disposed in the sealed chamber and arranged along a first direction. A size of the grid structure layer is less than or equal to a size of the capillary structure layer. The working fluid fills the sealed chamber.
