Problems solved by technology

It has the advantages of small refrigerant charge, avoiding the phenomenon of heat exchange tubes bursting due to freezing, and solving the problem of oil return. It is widely used in various heat pump refrigeration systems. The disadvantages are: the processing technology is relatively complicated, It is difficult to clean the outside of the heat exchange tube, and the anti-corrosion treatment of the flow cavity on the heat exchange side (sea water) inside the shell and outside the heat exchange tube is difficult
As a marine heat pump dry evaporator (condenser) used in a marine heat pump refrigeration system, its heat exchange side (seawater) is seawater with strong electrochemical corrosion, and a marine heat pump dry evaporator with a conventional structure or simple anti-corrosion treatment ( Condenser) cannot fully meet the requirements, so the heat pump refrigeration system is severely restricted in marine products, restricting the development and wider application of marine heat pump refrigeration systems and related products

Abstract

The invention discloses a novel marine heat pump type dry evaporation (condensation) device which comprises a shell and end covers, wherein the end covers are arranged at the two ends of the shell; the shell comprises a pipe plate; the end covers and the pipe plate are connected through sealing gaskets; baffle plates and heat exchange tubes are contained in the shell; the baffle plates and the heat exchange tubes are arranged in a vertical crossing distribution form. Thus, the novel marine heat pump type dry evaporation (condensation) device provided by the invention has the advantages of strong decay resistance and easiness in disassembling.

Description

technical field [0001] The invention relates to an evaporator, and more precisely relates to a novel marine heat pump type dry evaporator (condenser). Background technique [0002] The structure of the marine heat pump dry evaporator (condenser) is similar to that of the horizontal shell-and-tube evaporator, the difference is that the refrigerant liquid flows in the heat exchange tube in the ordinary marine heat pump dry evaporator (condenser) , while the heat exchange side (sea water) flows outside the heat exchange tube. It has the advantages of small refrigerant charge, avoiding the phenomenon of heat exchange tubes bursting due to freezing, and solving the problem of oil return. It is widely used in various heat pump refrigeration systems. The disadvantages are: the processing technology is relatively complicated, It is difficult to clean the outside of the heat exchange tube, and it is difficult to deal with the corrosion resistance of the flow cavity on the heat excha...
