Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a convective heat exchange device based on a vortex ring for low-speed circulating air supply. Background technique [0002] The heating source consumption of towns in northern my country accounts for 36% of the total building energy consumption in the country, and is the largest component of building energy consumption. The average energy consumption is 2-4 times that of developed countries with similar climates. When there is no one inhabited for a medium or long term, the heating is not stopped. When the heating is overheated, it is better to open the window than to close the valve. The waste of heat energy caused by these factors is as high as 20% of the total heat energy, worth tens of billions of yuan. [0003] The initial cost of central heating in southern my country is very high, and the large-scale construction costs are high, making it difficult to centraliz...

AI Technical Summary

Problems solved by technology

[0003] The initial cost of central heating in southern my country is very high, and the large-scale construction costs are high, making it difficult to centrally heat

[0004] Domestic single heating type heaters have disadvantages such as low overall heating efficiency of the room and uneven heating

Air-supply heaters mainly rely on ordinary wind to transmit heat, which requires high wind speed for long-distance transmission, and the user experience is not good. Existing heaters have disadvantages such as high power and fire hazards.

[0005] The existing vortex ring generation method mainly relies on splints or pistons to push a section of fluid column, and the vortex ring is generated by the curling of the fluid column at the outlet.

Increasing the outlet growth rate will reduce the ventilation volume of the vortex ring, and the movement speed of the splint piston is limited by the motor and cannot be greatly increased

Therefore, the ventilation volume and propagation speed of the vortex ring are often not balanced, and the heating demand cannot be met.
