It is a bent shape, one end of which is connected to the capillary air inlet, and the other end is connected to the capillary air outlet. The capillary air outlet is connected to the side of the wall of the air outlet pipe. die. The device utilizes changing the original straight-shaped capillary tube into a bent-shaped capillary tube, so that not only the heat exchange efficiency can be greatly improved, but the manufacturing cost is also low.

Description

A bent capillary network heat exchange device

technical field

The utility model relates to the field of heat dissipation, in particular to the field of capillary network heat exchange.

Background technique

The outstanding advantage of the capillary network heat exchange device is that it can effectively utilize low-grade energy, especially for renewable energy (such as solar energy, and the energy contained in soil, groundwater, air, sewage, surface water, power plant wastewater, etc.). The heating device can also improve the energy efficiency of the air-conditioning system, achieve energy saving, emission reduction, environmental protection and improve the quality of buildings. At the same time, the capillary network heat exchange device is combined with ground source heat pump or air source heat pump, plus reasonable control to form an energy-saving system, which can save energy up to 70%; if it is equipped with solar energy and cold and heat energy storage system, energy saving can reach 90% %about. It can be seen that the capillary network heat exchange device is closely related to "energy saving, emission reduction, consumption reduction, and building quality improvement", and has great prospects for promotion and application.

At present, capillary network heat exchange devices generally have low heat exchange efficiency, which makes them unable to be popularized and applied in a large area. Although there are some new capillary network heat exchange devices, some accessories are arranged on the inside and outside of the tube wall to improve the heat exchange efficiency, but its manufacturing cost is relatively increased a lot.

Utility model content

In order to solve the above problems, the utility model proposes a capillary network heat exchange device with high heat exchange efficiency and low manufacturing cost.

The technical scheme of the utility model is as follows: a bent capillary network heat exchange device, including an air inlet, an air inlet, a capillary air inlet, a capillary, a capillary air outlet, an air outlet, an air outlet, a vertical bracket, and a horizontal bracket , a valve, the valve is arranged at the inlet pipe mouth and the outlet pipe mouth, one end of the air inlet pipe is the air inlet pipe mouth, and the other end pipe mouth is sealed, and the capillary air inlet is communicated with the pipe wall side of the air inlet pipe , one end of the capillary is connected to the capillary inlet, the other end is connected to the capillary outlet, the capillary outlet is connected to the wall side of the outlet pipe, one end of the outlet pipe is the outlet pipe, and the other end is sealed , the vertical support is divided into two left and right sides arranged on both sides of the capillary, the two ends of which are respectively welded on the air inlet pipe and the air outlet pipe, and the two ends of the horizontal support are welded on the vertical support. The vertical support and the horizontal support mainly play the role of fixing the capillary network heat exchange device.

The capillary is bent and made of copper. First, each bend can increase the degree of turbulence of the flowing gas in the capillary, which increases the heat exchange efficiency of the gas; The contact area is larger, which increases the heat transfer efficiency of the gas; third, the thermal conductivity of the copper material is larger, which can increase the heat transfer efficiency of the gas.

Beneficial effects of the utility model: the device utilizes the traditional straight-shaped capillary into a bent-shaped capillary, not only the heat exchange efficiency can be greatly improved, but also the production cost is not high.
