Embodiment Construction

[0013] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0014] Heat pump air conditioner spoiler tube shell dry heat exchanger, including shell 1, copper tube 2, front end cover 3, rear end cover 4 and spoiler 5; the two ends of the shell 1 are respectively welded with a front bottom plate 15 and a rear bottom plate 16. The front bottom plate 15 is a circular plate, which is welded to the front end of the shell 1, and has holes; the rear bottom plate 16 is a circular plate, which is welded to the rear end of the shell 1; The shell 1 is a relatively thin shell, and the front and rear parts cannot be installed in the form of bolts or flanges. Therefore, after the front bottom plate 15 and the rear bottom plate 16 are welded and installed, the front bottom plate 15 and the rear bottom plate 16 can be opened. Bolt holes or flange holes for easy installation ...

Abstract

A heat pump air conditioner turbulence tube-shell dry-type evaporator comprises a shell, a copper tube, a front end cover, a rear end cover and turbulence plates. An exhaust hole is in threaded connection with a sleeve, and the sleeve is provided with an exhaust valve; the inner wall face and the outer wall face of the copper tube are both surfaces with threads; the copper pipe serving as a mediumchannel is divided into two systems; the rear end cover is welded to the rear end of the shell and formed by welding a cylindrical shell and part of the spherical face; and the turbulence plates aresegments larger than semicircles, and the segments of the adjacent turbulent plates are located in the vertical upper and lower sides. The shell occupies all spaces of the whole evaporator, therefore,by forming a water inlet, a water outlet, a medium inlet and a medium outlet in the shell in advance, a large quantity of the spaces can be saved, and the design of a main machine is optimized; the water inlet, the water outlet, the exhaust hole and a drainage hole are all in threaded connection, so that the heat pump air conditioner turbulence tube-shell dry-type evaporator is convenient to mount and easy to maintain and repair; and relative to a mode of flange connection, the fault rate is lower.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning, in particular to a heat pump air-conditioning spoiler shell dry heat exchanger. Background technique [0002] The central air conditioner uses the form of centralized cooling to provide cold water for the entire building, and then transmits the cold energy to each room step by step through heat exchange components such as fan coil units. Although the building structure generally reserves a certain space for the central air-conditioning unit, the evaporator of the central air-conditioning chiller has a variety of forms, including shell-and-tube heat exchangers, plate heat exchangers and other structures, which need to occupy a large area. Space. Especially when the demand for cooling capacity is particularly huge, when multiple chillers are required to work at the same time to meet the cooling capacity requirements, it is necessary to arrange as many evaporators as possible in th...
