Condensation type heat pump

Abstract

The invention relates to the technical field of heat exchange devices, in particular to a condensation type heat pump. The condensation type heat pump comprises a heat exchanger, wherein the heat exchanger comprises a shell, a heat transfer pipe, a pipe plate, a baffle plate, a partition plate and a first cavity, a motor is fixedly connected with the pipe plate, the output end of the motor penetrates through the pipe plate and is fixedly connected with a worm, the other end of the worm penetrates through the baffle plate and then is rotationally connected with the other pipe plate, and the worm is in threaded connection with the baffle plate. According to the condensation type heat pump, the worm drives the baffle plate to clean water scales on the surface of the heat transfer pipe and the inner wall of the shell, and then the water scales are suspended in water after being cleaned and discharged from a fourth connector along with water flow, so that the purpose of cleaning the water scales in the heat exchanger is achieved, the situation that the water scales are attached to the heat transfer pipe and the inner wall of the shell is prevented, the heat transfer efficiency of the heat exchanger is ensured, meanwhile, the situation that the heat exchanger is blocked due to scale accumulation is prevented, the using effect of the heat exchanger is guaranteed, and then the using effect of the condensation type heat pump is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a condensation heat pump. Background technique [0002] Condensing heat pump is an innovative heat pump technology that uses air source heat pump to realize the function of water source heat pump. Compared with heat pump, it has the characteristics of wide application range and low operating cost. Condensing heat pump is composed of compressor, heat exchanger, evaporator and controller.

[0003] For example, a Chinese patent with application number CN202021165924.4 discloses an anti-fouling air source heat pump heat exchanger, including a heat exchanger body, which is a cylindrical structure, including an outer shell, an inner shell, and a set The spiral coil between the inner shell and the outer shell, the spiral coil is provided with a water exchange channel; the spiral coil includes a water inlet and a water outlet, both of which protrude to the outside of the outer shell, and the water inlet It is located below the water outlet; the inner wall of the spiral coil is provided with an anti-fouling coating; the heat exchanger includes a spiral coil, and the inner wall of the spiral coil is corrugated. When the refrigerant is in a liquid state, it generates turbulent flow motion to obtain high-efficiency heat transfer; at the same time, its inner wall is coated, and the coating is closely combined with the inner wall of the spiral coil, which has high wear resistance and corrosion resistance; but the technical solution The spiral coil needs to be coated with four layers of different coatings on the inner wall of the spiral coil during production. The manufacturing process is cumbersome, and the four layers of coating need to be coated on the inner wall of the spiral coil. High, which in turn causes the limitations of the program
