Household radiator with coupled spraying humidifying and intensified convection heat exchange

Abstract

The invention relates to a household radiator with coupled spraying humidifying and intensified convection heat exchange. The household radiator comprises radiator bodies and a spraying humidifying device. The spraying humidifying device comprises an ultrasonic humidifier and a porous spraying guide pipe. The ultrasonic humidifier is arranged on the left sides or the right sides of the radiator bodies, or the ultrasonic humidifier and the radiator bodies can be connected into a whole through a clamp. The porous spraying guide pipe is arranged in longitudinal gaps of the columnar radiator bodies or on the side faces of the panel radiator bodies, or the porous spraying guide pipe is fixed to the bottoms of the radiator bodies through a clamp or a support. One end of the porous spraying guide pipe is connected with a humidifying device mist outlet, and the other end of the porous spraying guide pipe is provided with a screw plug used for draining condensed water. A plurality of pores are formed in the pipe wall of the spraying guide pipe. Coupling and intensifying of spraying humidifying and convection heat exchange are achieved, the heat exchange efficiency, the radiating capacity and the humidifying device spraying evaporation efficiency of the household radiator are remarkably improved, the effect that the stable and comfort heat and humid environment indoor is maintained can be ensured, and meanwhile, the energy consumption and equipment initial cost of the heat system can be reduced.

Description

technical field [0001] The invention relates to a method for enhancing heat exchange of a household radiator based on the principle of spray cooling, in particular to a household radiator coupled with spray humidification and enhanced convection heat exchange. The invention realizes the coupling and strengthening of spray humidification and convective heat exchange, significantly improves the heat exchange efficiency and heat dissipation of household radiators, and the spray evaporation efficiency of humidifiers, and can not only ensure a stable and comfortable hot and humid environment indoors, but also Reduce the energy consumption and equipment initial investment of the heating system. Background technique [0002] In winter in the north, the heating system can create a warm indoor thermal environment. However, due to the low temperature and low air humidity in the north, the heating process is likely to cause the relative humidity of the indoor air to decrease, resulting...

Problems solved by technology

CN201520247318.X proposes a heating radiator with humidification function. This scheme connects the radiator with the humidifier through a one-way valve, and directly introduces the hot water in the radiator into the humidifier. Although the evaporation rate of high-temperature water increases , The indoor humidification effect is improved, but this method is easy to cause serious water loss in the heating pipe network, which is not conducive to the economic operation of the heating system

[0005] There are many design schemes to improve the effect of spray humidification by using the high temperature conditions near the radiator, but no one has noticed that the local air flow speed-up disturbance effect and cooling and cooling effect produced by spray humidification can significantly improve household heat dissipation. The convective heat transfer coefficient and heat transfer temperature difference of the radiator help to strengthen the convective heat transfer process of the radiator; in addition, there are no relevant patents or literature reports that mention that the organization of the spray humidification process should ensure that the indoor hot and humid environment meets human comfort. on request
