Hot water heat exchanger

Abstract

The invention discloses a hot water heat exchanger. A gas collection barrel is arranged in the middle of a heat exchanger body. A water outlet pipe is arranged in the middle in the gas collection barrel. A first refrigerating fluid gas pipe is arranged on one side of the water outlet pipe. A first refrigerating fluid liquid separation head is arranged at the top of the first refrigerating fluid gas pipe. A first branch refrigerating fluid pipe is arranged at the top of the first refrigerating fluid liquid separation head. A second refrigerating fluid gas pipe is arranged on the other side of the water outlet pipe. A second refrigerating fluid liquid separation head is arranged at the top of the second refrigerating fluid gas pipe. A second branch refrigerating fluid pipe is arranged at thetop of the second refrigerating fluid liquid separation head. A water inlet pipe is arranged at the bottom in the gas collection barrel. An inner container is arranged on the outer side of the gas collection barrel. A heat preservation layer is arranged on the outer side of the inner container. A shell is arranged on the outer side of the heat preservation layer. According to the hot water heat exchanger, the height of a pipe opening of the water outlet pipe is larger than that of the gas collection barrel, through the principle that the upper portion is hot and the lower portion is cold, itcan be conveniently guaranteed that the temperature of cold water injected into the heat exchanger body does not influence the hot water temperature of output water, and the heat exchange effect of the heat exchanger body is enhanced.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a hot water heat exchanger. Background technique [0002] The hot water heat exchanger is a device that increases the temperature of the water by absorbing the heat released by the high-temperature and high-pressure refrigerant vapor discharged from the compressor. It is widely used in indoor environments because of its low cost and convenient use. Among them, most of the hot water heat exchangers currently used have disadvantages such as simple structure, poor heat transfer effect, low work efficiency, short service life, and serious energy waste. [0003] Therefore, it is necessary to design a hot water heat exchanger to solve such problems. Contents of the invention [0004] The object of the present invention is to provide a hot water heat exchanger to solve the problems raised in the background art above. [0005] In order to achieve the above object, the present...
