[0002] Wire-tube condensers are a common type of condenser used in housings. Their basic structure consists of iron pipes and steel wires welded together, with an electrophoretic coating on the surface. There are two types of appearance: one is a flat sheet structure, externally mounted on the housing; the other is folded into an "S" shape, rolled into a circle, or flattened oval, with a fan inside the compressor compartment of the housing. Both structures are limited by the material of the iron pipe itself, resulting in a relatively large bending radius and correspondingly large volume. Alternatively, because it is made from a single folded tube, the tube is long, resulting in high resistance and requiring a high-performance compressor. Utility Model Content
