Abstract
The invention relates to a dry type evaporator for a heat pump unit. The dry type evaporator for the heat pump unit comprises a shell, a copper pipe, a front end cover, a rear end cover and spoilers.A front bottom plate and a rear bottom plate are welded to two ends of the shell; the front bottom plate is a circular plate and is welded to the front end of the shell; an inner wall surface and an inner wall surface of the copper pipe are surfaces with screw threads; sleeve pipes are welded to a medium inlet and a medium outlet; the rear end cover is welded to the rear end of the shell, and is formed by welding a cylindrical shell and a partial sphere; the multiple spoilers are arranged; and a plurality of fixing rods are arranged on each spoiler in a penetrating way. According to the dry type evaporator for the heat pump unit provided by the invention, the shell is a thinner shell body, and parts on a front end and a rear end cannot be installed by adopting bolts or flanges, so that after firstly welding and installing the front bottom plate and the rear bottom plate, bolt holes or flange holes can be formed in the front bottom plate and the rear bottom plate, and other parts can beinstalled conveniently.
Description
technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a dry evaporator of a heat pump unit. 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 the same space. [0003] D...
