Abstract
The utility model discloses an internal eddy-current self-circulation type external wall heating water tank. A heating element is attached to the outer wall surface of a liner enclosure of the water tank. The internal eddy-current self-circulation type external wall heating water tank is characterized in that a cylindrical thin-wall current-isolating device is arranged inside the liner; intervals are respectively reserved between the upper end part and the lower end part of the current-isolating device and the liner enclosure; a water body in the liner is divided into an inner runner and an outer runner by the current-isolating device; when the outer wall surface of the liner is heated, the water body of the outer runner ascends by means of buoyancy lift to the upper end part of the current-isolating device and then downward flows into the inner runner, so that the whole water body forms a large eddy current. Compared with the water tank omitting the current-isolating device, the internal eddy-current self-circulation type external wall heating water tank improves the eddy current state of the water body, enhances the self-circulation power and improves the heat exchange coefficient in the liner. By using the utility model, the heat exchange performance can be improved when the heat exchange area is the same and the heat exchange area can be reduced when the heat exchange amount is the same so as to save the cost. In addition, the hot water yield can be improved to be about 90-95 percent; and the internal eddy-current self-circulation type external wall heating water tank has simple and reliable structure and process and is applicable to water-water heat exchange, electric heating, steam or hot air or smoke gas heating as well as water-storing heating containers of heat pump water heaters, fire tube or smoke tube boilers and the like.
Description
Technical field
The utility model relates to a kind of interior eddy current self-circulation type outer wall heating water tank, belongs to the heat power engineering field.
Background technology
The heat storage type cisten mechanism is widely used in electric heater; Teat pump boiler; gas-fired water heater; steam heater; field such as hot-air or Smoke-heating device; the drum part of fire tube or flue tube boiler also can be regarded heat storage water tank as; when above-mentioned water tank is provided with the externally-wound type heating element heater when it; can fundamentally avoid problems such as more serious corrosion that internal heater need solve and fouling; but its thermal resistance can increase usually; when add heat will cause when identical need be bigger heat exchange area; its heat transfer temperature difference often also needs to increase, thereby can cause the reduction of efficiency of energy utilization.Therefore, how effectively reducing heat transfer resistance is the effective way of improving its heat exchange property, reducing heat transfer area.
The analysis showed that through heat transfer resistance water side thermal resistance is occupied larger proportion in its courage in entire thermal resistance to the outer wall heating water tank.Analyze water body nowed forming and heat exchange situation thereof in the water tank, usually upwards flow near the part of inner bag casing wall in its inside, to top then flow downward, formation is than maelstrom, but mixed flow is comparatively serious between the uplink and downlink current, and upper and lower end parts etc. locate to exist the eddy current than small scale, further influence and reduced flowing velocity, thereby weakened the water side coefficient of heat transfer in the courage, promptly increased the heat exchange thermal resistance, must need bigger heat transfer temperature difference and more heat transfer area to realize required heat exchange amount.Simultaneously, the bottom water body is difficult to effectively be heated, and has reduced the hot water productive rate of heat storage water tank.
The utility model content
The purpose of this utility model and task are at the problem of above-mentioned existence, by inner the employing every the stream device of inner bag the water body flow pattern being divided into inside and outside two parts, effectively to strengthen maelstrom mobilization dynamic and speed, thereby strengthen heat exchange property, the minimizing heat transfer area.
Specific descriptions of the present utility model are: eddy current self-circulation type outer wall heating water tank in a kind of, by forming every stream device, insulation construction and water pipe in inner bag casing, heating element heater, the courage, wherein heating element heater (3) is attached at the outside wall surface of casing (2), it is characterized in that inner bag inside is provided with tube-like thin-wall every stream device (1), the upper inside wall face of its upper end and casing (2) has at interval, the lower inner wall face of bottom and casing (2) has at interval, every the stream device with courage in water body be divided into outer flow passage (6) and inner flow passage (7) two parts.When the inner bladder outer wall face was heated, the water body of outer flow passage relied on buoyancy lift up, and to transfer to flow into inner flow passage downwards behind stream device upper end, whole water body forms a maelstrom.
Can adopt thin-walled plastic to surround cylindrical structure every stream device (2).Certainly then should adopt corrosion resistant metal material or resistant to elevated temperatures plastic material etc. for the contour tender feeling condition of flue tube boiler.
Heating element heater (3) can adopt externally-wound type hot-water coil pipe structure, heat tape or heater strip structure, steam or hot-air or flue gas heater structure, Teat pump boiler condenser pan tubular construction or fire tube or flue tube boiler heat-transfer surface structure.
The utility model with do not install additional every stream device compare, improved water body eddy current state, strengthened self-circulation power, promoted the courage tube internal heat exchange coefficient, can improve heat exchange property when heat exchange area is identical, can effectively reduce heat exchange area when the heat exchange amount is identical to save cost, also the hot water productive rate can be brought up to about 90 ~ 95%, actual measurement shows the weight that can save heat exchange material about 20～30%.This apparatus structure simple and reliable process is applicable to the fields such as water storage heating container of the heat exchange of water water, electrical heating, steam or hot-air or flue gas heating, Teat pump boiler, fire tube or flue tube boiler etc.
