Description
Technical field
The utility model relates to heat exchanger, is specifically related to a kind of enamel hot pipe heat exchanger.
Background technology
Heat pipe is a kind of heat transfer element with high heat conductivility; It is through transmitting heat in the evaporation of Totally enclosed vacuum intraductal working medium with condensing, but the heat transfer area with high thermal conductivity, good isothermal, cold and hot both sides can change series of advantages such as remotely transferring, temperature controllable arbitrarily.The heat exchanger of being made up of heat pipe has advantages such as heat transfer efficiency height, compact conformation, fluid-pressure drop be little.Gravity assisted heat pipe has obtained using widely because of the cost of its simple structure and economy; Its operation principle is: heat pipe heat side absorbing waste gas heat, and heat passed to intraductal working medium (liquid state), and working medium heat absorption back is a steam with the formal transformation of evaporation and boiling; Steam rises to the heat release side under differential pressure action; Condense into liquid simultaneously and emit the latent heat of vaporization, heat is passed to the cold fluid of heat release side, and condensed fluid relies on gravity reflux to heat side.
Existing heat exchange of heat pipe; Its basic structure comprises casing, is provided with the dividing plate in hot-fluid chamber that cabinets cavity is separated into cold flow chamber and the bottom on top in the casing, is connected with many heat pipes on the dividing plate; The hypomere of many heat pipes is positioned at the hot-fluid chamber, and the epimere of many heat pipes is positioned at the cold flow chamber.The cold flow chamber relative both sides be respectively equipped with the cold fluid entrance and exit, the hot-fluid chamber relative both sides be respectively equipped with the hot fluid entrance and exit.
Start rapid, thermal conductivity advantages of higher because heat exchange of heat pipe has, also be widely used in the heat exchange of boiler smoke.Heat exchange of heat pipe is arranged on the outside flue of afterbody or the boiler of boiler; Flue gas is passed through from the hot-fluid chamber, air or water are passed through from the cold flow chamber, heat pipe absorbs the heat of low-temperature flue gas; Be used for adding hot-air and send into boiler auxiliary combustion, perhaps add hot water in order to life heating and boiler feedwater.But, have a strong impact on the life-span and the security of operation of heat exchanger because flue-gas temperature is low and also have sour gas such as sulfur trioxide and cause the heat pipe acid corrosion.In addition, the surface area of existing its heat pipe of heat exchange of heat pipe is little, has the problem of heat exchange weak effect.
Summary of the invention
The technical problem that the utility model will solve provides a kind of good effect of heat exchange, enamel hot pipe heat exchanger that corrosion resistance is strong.
In order to solve the problems of the technologies described above; The utility model provides a kind of enamel hot pipe heat exchanger with following structure; Comprise casing, be provided with the dividing plate in hot-fluid chamber that cabinets cavity is separated into cold flow chamber and the bottom on top in the casing, be connected with many heat pipes on the dividing plate; The hypomere of many heat pipes is positioned at the hot-fluid chamber; The epimere of many heat pipes is positioned at the cold flow chamber, and its design feature is all to be connected with helical fin on the outer surface of hypomere and epimere of said heat pipe, and said heat pipe is positioned at the pipeline section in hot-fluid chamber and is connected on the outer surface of the helical fin on this pipeline section and is equipped with enamel layer.
Said heat pipe is positioned at the pipeline section in cold flow chamber and is connected on the outer surface of the helical fin on this pipeline section and also is equipped with enamel layer.
The thickness of said enamel layer is 0.15-0.25mm.
Through on heat pipe, establishing helical fin; To increase heat exchange area; Make the advantage that the utlity model has good effect of heat exchange; Through on the surface of heat pipe and helical fin, establishing enamel layer, and enamel layer has stronger wear-resistant corrosion resistance, thereby makes the utility model have the advantage of wear-resistant corrosion-resistant and long service life again.
