Second adverse current barrel type heat exchanger

Abstract

The present invention relates to a secondary counter flow barrel type heat exchanger, which comprises an outer barrel body with the upper part connected with a hot air inlet, a hot air outlet, a tap water inlet and a tap water outlet respectively. The hot air outlet is communicated with the inner cavity of an outer barrel body; an inner barrel body is arranged in the outer barrel body, the upper end of the inner barrel body is connected with the tap water outlet, and the tap water outlet is communicated with the inner cavity of the inner barrel body; the hot air inlet is connected with a heating pipe, the heating pipe is inserted into the inner barrel body and penetrates form the bottom part of the inner barrel body and is communicated with the inner cavity of the outer barrel body. The periphery of the inner barrel body is coiled with a screwy tap water heat absorbing pipe, the head end of the tap water heat absorbing pipe is connected with the tap water inlet, and the tail end is connected with the bottom part of the inner barrel body and is communicated with the inner cavity of the inner barrel body, and the present invention forms a secondary counter flow heat exchanging structure. The present invention saves the heat absorbing copper pipe in the original patent, thereby the cost is low, the volume is small, the space is small, the installation is easy and the acid cleaning is convenient. The water temperature can reach more than 38 DEG C, and is incessant. The materials are chosen stainless steel and a red copper pipe, and the service life is as long as 10 years.

Description

Technical field [0001] The invention relates to a heating heat exchanger that can be installed and used on a heating pipe network for heating and hot water bathing, in particular to a secondary countercurrent tube that can be used for bathing in low-temperature heating areas and anti-scaling for users in high-temperature heating areas Type heat exchanger. Background technique [0002] The applicant has applied for multiple patents and obtained patent rights for the heat exchanger installed on the heating pipe network for heating and heat exchange bathing. This patent application is a creative improvement based on the original patent. Compared with the original patent, there are essential differences. The original patents related to the present invention are as follows: [0003] The patent number is 98220257.1 and the utility model name is "heating shower heat exchanger". It relates to a heat exchanger for heating showers. It consists of a left water tank, a right water tank, a co...

AI Technical Summary

Problems solved by technology

Only heat-absorbing copper pipes can be replaced, but after 2 to 5 heating periods, the user has to pay a large sum of money, resulting in increased use costs, waste of materials, and shortened product life cycle
