Abstract

The invention relates to the field of heat exchangers, in particular to a shell and tube heat exchanger. The shell and tube heat exchanger comprises a heat exchanger shell and a tube pass assembly arranged in an inner cavity of the heat exchanger shell. The tube pass assembly comprises a tube bundle support, a copper tube, a distributor and a collector, wherein the copper tube is arranged on the tube bundle support, and the distributor and the collector are connected with the ends of the copper tube correspondingly. A liquid inlet and a liquid outlet which are communicated with an inner cavityof the heat exchanger shell are formed in the heat exchanger shell. The heat exchanger shell comprises a barrel and end plates welded to the edges of openings in the two ends of the barrel in a sealed mode. The shell and tube heat exchanger has the advantages that the structure is simplified, machining is convenient, cost is reduced, and sealing performance is guaranteed.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a shell and tube heat exchanger. Background technique [0002] A shell and tube heat exchanger is a heat exchanger composed of a group of tube bundles or coils installed in a shell. Two heat transfer media, one in the tube and the other in the tube shell, conduct heat transfer through the tube wall, generally horizontal. It is mainly used for the host equipment in the air-conditioning heat pump industry. It can be used as an evaporator or a condenser. The heat exchange medium is generally water and cold medium (refrigerant). Compared with other types of heat exchangers (tube heat exchangers, plate heat exchangers, high-efficiency tank heat exchangers, etc.), shell and tube heat exchangers have small water resistance and cold medium resistance, and have obvious price advantages. They are widely used in water-cooled screw units. , water source heat pump unit, water-cooled cabinet ...
