Improved condensation type gas warm bath dual-purpose heat exchanger

Abstract

The invention relates to an improved condensation type gas warm bath dual-purpose heat exchanger. The heat exchanger comprises a shell and a plurality of heat exchange fins which are distributed in parallel in the horizontal direction and are mounted in the shell; a water passing channel is formed between adjacent heat exchange fins, and a left water pipeline and a right water pipeline which are communicated with the interior of the shell are arranged on the left side and the right side of the shell respectively; the left water pipeline and the right water pipeline are both communicated with the water passing pipeline, and the water passing pipeline is made of an aluminum alloy; a continuous bending body is integrally formed, and a plurality of through holes are formed in each side plate of the bending body in the length direction of the side plate; the through holes in two adjacent side plates correspond to each other in a one-to-one manner; and the heat exchange fins are in wave shapes. The improved condensation type gas warm bath dual-purpose heat exchanger has the beneficial effects that the heat exchanger is high in heat exchange efficiency, simple in structure, good in stability, high in strength, low in cost, high in appearance integrality, high in safety, and not prone to damage; and incrustation forming is prevented, and the heat exchange noise is reduced.

Description

technical field [0001] The invention relates to an improved condensing gas heating bath dual-purpose heat exchanger. Background technique [0002] The existing heat exchanger includes a shell and several heat exchange fins distributed in parallel in the horizontal direction in the installation shell, and water passage pipes are arranged between adjacent heat exchange fins, and the inner wall of the water passage pipes The disadvantages are as follows: 1. The water passage is a flat tube, and the inner wall is not full of tooth-shaped protrusions. This way the channel area is small, and the heat exchange effect is not good after the water flow speed is increased. Although there are tooth-shaped The protrusions increase the heat exchange, but the gaps of the tooth-shaped protrusions are easy to clog and are not easy to clean. The invention changes the structure of the water channel, increases the area of ​​the water channel, reduces the flow velocity, increases the heat excha...

Problems solved by technology

2. The original heat dissipation fins are rectangular, and the fin spacing is small, which is easy to block and difficult to clean

[0003] The heat exchangers of condensing gas heating dual-purpose furnaces are mostly made of stainless steel and carbon steel, which have the defects of heavy weight, loud combustion noise, large volume, low heat transfer efficiency and poor corrosion resistance; and the service life of the heat exchanger is short, easy to Scaling is not easy to clean, and water channel blockage cannot be found in time, which brings great troubles to users
