Heat-convection heat exchange device based on vortex ring low-speed circulation air supply

Abstract

The invention discloses a heat-convection heat exchange device based on vortex ring low-speed circulation air supply. The heat-convection heat exchange device based on vortex ring low-speed circulation air supply comprises a combined heating device, an annular air supply device and a vortex ring air supply device, wherein the combined heating device is arranged at the upper end of the vortex ringair supply device; the annular air supply device is arranged outside the vortex ring air supply device in a sleeving way; and the upper end of the vortex ring air supply device and the upper end of the annular air supply device communicate with the combined heating device. According to the heat-convection heat exchange device based on vortex ring low-speed circulation air supply provided by the invention, the air supply speed and the heating efficiency are improved, the use experience of a heater is improved, the energy waste caused by uneven indoor temperature distribution is reduced, and theheat-convection heat exchange device based on vortex ring low-speed circulation air supply has remarkable energy conservation, emission reduction and socioeconomic performances, is broad in market application prospect, forms a heat circulation system, and realizes a heating system with low energy consumption and high efficiency.

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...

[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 haz
