火龙,就是北方部份地区的居民由睡火炕改为睡床后,集中了火炕和火墙的优点,逐步完善的一种新型实用的节能取暖设施。火龙,从构造上看似乎是将一个火炕划分为几个小炕,或是低矮的组合小火墙。火龙将火炕的竖向散热和火墙的横向散热集于一体,使之有更多的散热面积。火龙由于是位于床下伏地曲折的排烟散热体,所以也叫“床下火龙”或“地火龙”。
The dragon, which is the part of the residents in the northern part of the country, changed from a sleeping fire to a sleeping bed, concentrated the advantages of the fire and the fire wall, and gradually improved a new type of practical energy-saving heating facilities. From the point of view of structure, the fire dragon seems to be divided into several small dragonflies, or a combination of low fire walls. The fire dragon integrates the vertical heat dissipation of the fire and the horizontal heat dissipation of the fire wall to make it have more heat dissipation area. The dragon is also called “under-the-bed fire dragon” or “ground fire dragon” because it is located in the bed under the twists and turns of the smoke exhaust heat sink.
