The present invention involves a new type of dual -shaped winding tube heat exchanger, which is mainly composed of upper spiral tube beam, lower spiral tube and shell.The layer spiral entanglement is wrapped down to the bottom of the upper mid -core tube, and the backward winding up to form a two -way spiral winding method.The backward winding upwards forms a two -way spiral winding method.In the present invention, the upper spiral tube and the lower spiral tube are separated from each other. There is no effect on heat transfer between the two spiral tubes.The heat exchanges required by the pipeline fluid; the upper spiral tube and the lower spiral bundle are both a two -way spiral winding method, making the heat exchanger large, uniform heat exchanges, compact structure, and small land area.
Description
technical field [0001] The invention relates to heat exchanging equipment, in particular to a novel twin-flow winding tube heat exchanger. Background technique [0002] Heat exchanger is a device used to realize heat transfer, and it is widely used in chemical industry, oil refining, food, light industry, energy, pharmaceutical, machinery and other industrial sectors. Due to its reliable structure, mature technology, and wide application range, the shell-and-tube heat exchanger is the main structural form of heat exchange equipment at home and abroad. However, the shell-and-tube heat exchanger has disadvantages such as large volume and low heat exchange efficiency. The structure of the wound tube heat exchanger is more compact than that of the shell and tube heat exchanger which is widely used at present, and its heat exchange effect is also better. The wound tube heat exchanger is formed by winding the heat transfer tubes alternately in the shape of a helix in the space be...
