Problems solved by technology

[0004] However, since the heat exchanger is only refrigerated by the air forced by the fan, such conventional refrigerant condensation heat exchangers used in refrigeration systems are problematic, so the improvement of heat exchange efficiency is unduely restricted
Moreover, the above-mentioned heat exchanger must enhance the heat exchange efficiency by having a plurality of heat exchange fins, so, in order to achieve the required heat exchange rate, the volume of the heat exchanger will be unreasonably enlarged.
Furthermore, the increase in the volume of the heat exchanger also increases the volume of the refrigeration system of the heat exchanger

Abstract

A heater exchanger used to condense a refrigerant in a refrigeration system. The heat exchanger is designed to perform a heat exchanging operation by the use of latent heat of water vaporization, thus having improved heat exchanging efficiency as well as a reduced size. The heat exchanger includes an upper header having a refrigerant inlet port and distributing a refrigerant introduced into the upper header through the refrigerant inlet port; a plurality of heat exchanging tubes connected at upper ends thereof to the upper header and extending in a vertical direction; a lower header connected to lower ends of the heat exchanging tubes and gathering the refrigerant flowing from the heat exchanging tubes, the lower header having a refrigerant outlet port; and a water supply unit assembled with upper portions of external surfaces of the heat exchanging tubes, and feeding water to the tubes to cause a flow of water along the external surfaces of the tubes, thus allowing the water to absorb heat from the refrigerant flowing in the tubes.

Description

field of invention [0001] The present invention relates generally to a heat exchanger for a refrigeration system, and more particularly to a water-cooled heat exchanger for condensing refrigerant in a refrigeration system. Background technique [0002] As is well known in the industry, the refrigeration system for air conditioners includes a compressor, a refrigerant condensing heat exchanger, a refrigerant expansion device, and a refrigerant evaporating heat exchanger, and these components are sequentially connected to each other through refrigerant pipes to form a refrigeration circuit. When the compressor in the refrigeration circuit is running, the refrigerant circulates through the refrigeration circuit, and at the same time, the state of the refrigerant is changed repeatedly by sending or absorbing heat to the surroundings. In this way, the refrigeration system lowers the temperature in the room. [0003] In this refrigeration system for air conditioning equipment, th...
