Description

penetrating reverse heat exchanger

Technical field:

The utility model relates to the technical field of heat exchangers, in particular to a penetrating reverse heat exchanger.

Background technique:

In the field of heat energy recovery, heat exchangers are often used. The working principle of the most widely used water-medium heat exchanger is: through the input of cold water, the heat source transfers heat to the cold water, making the cold water warm up and turning it into hot water. Water storage and utilization. At present, the heat exchanger is composed of two socketed curved pipes, one of which is used for the flow of heat source, and the gap between the other pipe and the previous pipe is used for the flow of cold water. The bending of the pipe can increase the heat exchange distance, through this The biggest disadvantage of this kind of heat exchanger is that the efficiency is not high; in addition, this kind of socketed pipes are generally very regular, that is, the gap between the two socketed pipes is relatively uniform, which also affects One of the factors of heat exchange efficiency.

Utility model content:

The purpose of this utility model is to provide a penetrating reverse heat exchanger for the deficiencies of the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes first and second heat source pipes which are nested with each other, and a water pipe is set between the first and second heat source pipes, and the main pipe composed of the three pipes forms a plurality of bending parts.

The gaps between the pipes in the pipes are different.

The beneficial effect of the utility model is that: it adopts three pipes to form the effect that the inside and outside of the cold water are wrapped by the heat source, thereby greatly improving the heat exchange efficiency; in addition, the gaps between the pipes are different, so that turbulent flow is formed in the pipes , can also improve the heat exchange efficiency.

Description of drawings:

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the local structural representation of the utility model;

Fig. 2 is a structural representation of the utility model;

Fig. 3 is a schematic diagram of the working principle of the utility model.

Detailed ways:

See accompanying drawings 1, 2, 3, the utility model comprises first and second heat source pipes 10 and 20 which are nested with each other, and a water pipe 30 is sleeved between the first and second heat source pipes 10 and 20, and the water pipe 30 is connected to For cold water a, the first and second heat source pipes 10 and 20 pass through heat source b, and the flow direction of cold water a and heat source b is opposite, so that the effect that the inside and outside of cold water a is wrapped by heat source b is formed, which greatly improves Heat exchange efficiency; the main tube composed of these three pipes forms multiple bends, generally bent into waves, increasing the distance of heat exchange.

The gaps between the pipes in the pipes are different; during processing, the three pipes can be socketed together first, and then the main pipe is bent and formed. The first heat source pipe 10 is made of stainless steel, and the second heat source pipe 20 And the water pipe 30 is made of copper material. When bending, the second heat source pipe 20 and the water pipe 30 will be deformed, and the distance between the bent parts will be reduced. This structure with different gaps will make the heat source and cold water flow in the pipes to form turbulence. flow, thereby improving the heat exchange efficiency; the hot water produced by the utility model is about 10 degrees higher than that produced by the heat exchanger without the aforementioned structure.

The utility model has the advantages of simple structure and better use effect.
