Description

Self-cooling quick-heating body and heat exchange system

Technical Field

The utility model relates to a quick-heating field specifically belongs to a self-cooling quick-heating member and heat transfer system.

Background

The current heating body is mainly constructed by a stainless steel metal tube, the surface of the stainless steel metal tube is coated with an insulating layer, and then a resistance wire is wound outside the insulating layer or a heating film is coated outside the insulating layer. Thus, a heating part is formed, and then sealing rings and end covers are respectively added at two ends of the metal pipe to form sealing and water inlets and outlets on the end covers. Since the heating speed is high, various problems such as local overheating due to the excessive temperature and non-uniform temperature of the heating body itself are easily caused.

In order to protect the heating body and prevent the heating body from being burnt due to overhigh temperature, one mode is that a plurality of temperature-maintaining fast switches are arranged on the surface of the heating body, and when the temperature of the surface of the heating body is overhigh, the temperature-maintaining fast switches are timely tripped to cut off a power supply, so that the heating body is protected; in another mode, if the temperature of the outlet water cannot be high, local overheating of water is easy to occur, so that a large amount of internal bubbles are generated, and the heat transfer of the heating body is blocked, so that the local temperature of the heating body is higher, and more bubbles are generated. The above solutions do not completely solve the drawback caused by too fast heating speed, but rather reduce the heat utilization rate, resulting in increased energy consumption.

Therefore, chinese utility model patent with patent number 201310346507.8 discloses an instant water heater, and in this water heater, be equipped with water inlet and delivery port on the water heater casing, be equipped with the heating member in the water heater casing, the inside heating pipe that is equipped with of heating member, the heating pipe both ends are equipped with cold water pipe and hot-water line respectively, cold water pipe and water inlet intercommunication, hot-water line and delivery port intercommunication, heat conduction casing of heating body suit, the winding has the cooling tube on the heat conduction casing, the water inlet is connected to cooling tube one end, and the cold water pipe is connected to the other end. Due to the structural design, the heat emitted by the heating body is absorbed by the heat-conducting shell, then the heat on the heat-conducting shell is absorbed by the water in the heat-radiating pipe, and finally the water in the heat-radiating pipe is heated and then returns to the hot water pipe, so that the water temperature of the water in the cold water pipe is increased.

The form of foretell water heater through winding the cooling tube on heat conduction shell body promptly not only can avoid the heating of heating member uneven, can also recycle the water after the heat exchange, avoids heat energy extravagant, but the scope that the cooling tube winding covered is less, adopts the water pipe water conservancy diversion to make the heat energy loss at the tip, and the cooling tube not with heating member direct contact, consequently can not thoroughly solve the local overheat scheduling problem that present heating member exists.
