许多家庭装修,为了单纯追求美观,往往把暖气片完全封闭,只留一处散热孔,如图一所示。从这种方式我们不难看出,它没有给空气的对流留出通道,仅仅靠辐射进行热传递,这样,就把大多数热能消耗在暖气罩内,大大降低了采暖的效果,使房间达不到预想的温度 画蛇添足得不偿失。 Many home improvements, in order to simply pursue beauty, often close the radiator completely, leaving only a cooling hole, as shown in Figure 1. From this approach, it is not difficult to see that it does not leave a channel for the convection of air. It only uses radiation for heat transfer. In this way, most of the heat energy is consumed in the heating hood, which greatly reduces the effect of heating and makes the room reachable. It is not worth the trouble to add the temperature to the expected temperature.
