Heat exchanger for low-temperature air source heat pump water module and manufacturing method of heat exchanger

Abstract

The invention discloses a heat exchanger for a low-temperature air source heat pump water module and a manufacturing method of the heat exchanger. A tank body of the heat exchanger is internally provided with a base, the base is provided with supporting rods, the supporting rods are provided with sliding devices, the sliding devices are vertically provided with metal rods, the metal rods are provided with laminated boards, the side faces of the laminated boards are provided with side pressing plates, and the side portions of the side pressing plates are provided with contact heads. The manufacturing method comprises the steps that firstly, the tank body is formed in a stretching manner; secondly, the base and the supporting rods are welded; thirdly, the sliding devices are installed; fourthly, the sliding devices and the metal rods are welded; fifthly, the sliding devices slide in; sixthly, the limiting region of a heat exchanging water pipe is positioned; seventhly, the side pressingplates are assembled; eighthly, the limiting region of the heat exchanging water pipe is arranged; ninthly, the heat exchanging water pipe is assembled; tenthly, the heat exchanging water pipe is installed; and eleventhly, the tank body is sealed. According to the heat exchanger for the low-temperature air source heat pump water module, the impact effect of a liquid working medium is reduced, theservice life of the heat exchanging water pipe is prolonged, the standing time of the working medium is prolonged, the heating and refrigerating effects are uniform, the heat exchanging water pipe isconveniently and precisely installed, and the installation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchanger manufacturing, and in particular relates to a heat exchanger for a low-temperature air source heat pump water module and a manufacturing method thereof. Background technique [0002] Introduction to air source heat pump: Air source heat pump is one of the most advanced energy sources at present. The working principle of air source heat pump is different from solar energy and ground source heat pump. Air source heat pump is free energy like solar energy and ground energy. The product of air source heat pump can be used in many fields such as domestic hot water, air conditioning, household heating, etc., and has become a symbol of high-tech and high-grade life. [0003] Low temperature air source heat pump water modules are widely used in newly built and rebuilt large and small industrial and civil building air conditioning heating and cooling projects, such as temporary housing, hotels, apar...

Problems solved by technology

However, in the actual heating and cooling process, the liquid working medium continuously impacts the water exchange pipe, and the connection between the water exchange pipe and the upper water pipe, and the connection between the water exchange pipe and the lower water pipe will become loose, resulting in liquid leakage. Moreover, the service life of the water exchange pipe is average, and the heating and cooling effects are uneven.
