Novel condenser for refrigerating system

Abstract

The invention discloses a novel condenser for a refrigerating system, and relates to the technical field of condensers. The condenser comprises a condenser body, wherein the condenser body comprises plate heat exchangers and Y-shaped fins; diversion pipes are arranged at one ends of two transverse channels, circulation interaction is achieved between the diversion pipes through flow guide holes formed in the plate heat exchangers, a cooling liquid inlet is formed in the outer end of one transverse channel of each cooling liquid circulating pipeline, and a condensate outlet is formed in the outer end of the other transverse channel of each cooling liquid circulating pipeline; and closed rings are welded on the transverse channels between the adjacent upper and lower plate heat exchangers in refrigerant circulating channels and the cooling liquid circulating pipelines in a spaced surrounding manner, and the closed rings of the refrigerant circulating channels and the cooling liquid circulating pipelines are alternately arranged. Condensing surfaces are vertical surfaces, so that the refrigerant circulation demand is greatly reduced, the temperature transfer is more uniform, the condensing speed is higher, and the condensing effect can be greatly improved; and the contact heat exchange area of a refrigerant and cooling liquid is greatly increased, and the condensing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of condensers, in particular to a novel condenser used in refrigeration systems. Background technique [0002] The condensers of the current refrigeration system can be divided into three categories according to the condensation method: water-cooled condensers, air-cooled condensers, and evaporative condensers. Among them, the evaporative condenser has a stronger cooling capacity and is often used in large-scale refrigeration systems. [0003] The evaporative condenser commonly used in refrigeration systems, the medium in the serpentine coil is a mixture of gas and liquid, which seriously scours the pipeline and requires regular maintenance; and there are phenomena such as easy blockage of the nozzle, easy fall off of the nozzle, and easy collapse of the water eliminator; there is a need Regular sewage discharge, regular cleaning of evaporative condenser and other problems, the operation and maintenance cost...

[0003] The evaporative condenser commonly used in refrigeration systems, the medium in the serpentine coil is a mixture of gas and liquid, which seriously scours the pipeline and requires regular maintenance; and there are phenomena such as easy blockage of the nozzle, easy fall off of the nozzle, and easy collapse of the water eliminator; there is a need Regular sewage discharge, regular cleaning of evaporative condenser and other problems, high operation and maintenance costs

Some refrigeration systems use plate heat exchangers in order to reduce the refrigerant charge, but the traditional plate heat exchangers have the problem of low heat exchange efficiency caused by uneven liquid separation. This invention describes a new plate heat exchanger, It can solve the problem of uneven liquid separation of traditional plate heat exchangers, which will greatly improve the application status of plate heat exchangers in refrigeration systems, and realize the wide application of plate heat exchangers in large-scale refrigeration systems, not only saving costs, but also It can also greatly improve the safety of refrigeration system operation
