Detachable upright heat exchanger

Abstract

The invention discloses a detachable upright heat exchanger. The detachable upright heat exchanger comprises a support, a flow guide barrel, a heat exchange pipe, a shell, a water inlet pipe and a drainage pipe. The flow guide barrel is vertically arranged on the support, and is sleeved with the matched shell from top to bottom; the combination position of the shell and the flow guide barrel are connected through a bolt to form a detachable sealing structure; the flow guide barrel is an open container with a bottom; spiral fins wound on the outer side of the barrel wall are matched with the shell to form an internally-arranged spiral water channel; the heat exchange pipe is placed along the spiral water channel; an inlet end connection pipe and an outlet end return pipe of the heat exchange pipe are led out of the bottom of the barrel; an overflow hole penetrating through the barrel wall is formed in the high end of the spiral water channel in the flow guide barrel; a through hole penetrating through the external barrel bottom of the barrel wall is formed in the lowest end of the spiral water channel in the flow guide barrel, and is used for being connected with the drainage pipe; the water inlet pipe is connected with the through hole in the barrel bottom of the flow guide barrel to form a water inlet channel. Because the shell is detachable, water scale can be removed in a barrier-free mode, and the heat exchange efficiency expectation is easily achieved.

Description

technical field [0001] The invention relates to a heat exchange device, in particular, the invention relates to a heat exchanger which can be easily disassembled for internal scale cleaning. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, the application requirements for heating, air conditioning, and domestic hot water are increasing, and corresponding energy conversion devices are required to meet these requirements. Today, the most economical and environmentally friendly energy conversion devices in this field use ground source heat pump technology. Heat exchangers are key components for energy conversion in these devices, and their performance determines product quality. There are many brands of commercial heat exchangers on the market with different structures, all of which can achieve the expected heat exchange effect. Usually, the heat exchange efficiency is 80% to 85%. However, the h...
