Background

The radiator is used as a device for heating in winter, and the heat radiation capability of the radiator directly influences the indoor thermal comfort degree. The heat transfer mode of the current radiator is mainly based on convection and radiation. Among them, the convection type radiator is widely used in the south. The heat exchange of the convection type radiator mainly depends on the flow of indoor air, the air enters the radiator, is heated and then flows out of the radiator, and the hot air flowing out of the radiator and the indoor air exchange heat in a convection manner, so that the purpose of increasing the indoor temperature is achieved by circulation. Therefore, the flowing state of the indoor air can affect the heat exchange rate of the radiator and the indoor air, the indoor air flows slowly, the cold and hot of the air in a room are uneven, and the thermal comfort of indoor personnel is affected.

The existing radiator technology has no method for strengthening indoor air flow, the radiator can not be added with a fan to strengthen indoor convective heat transfer like the traditional air conditioning equipment, and the radiator mainly depends on the heat of high-temperature hot water to meet the indoor load requirement. And the used radiator of heating does not need external electric power, and the radiator size is mostly flat, if increase devices such as fan that strengthen the convection heat transfer can increase the manufacturing and the installation cost of radiator.
