Description

The heat pipe heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, especially a kind of heat exchanger that utilizes heat pipe to carry out exchange heat.

Background technology

On industrial production, the heat exchanger that arrives commonly used carries out exchange heat, makes medium cooling, and the heat of medium can be utilized simultaneously.Heat pipe in the heat exchanger commonly used is gravity assisted heat pipe or two-phase thermal siphon, they are to become steam state in other end heat release after at one end absorbing heat by the working media in the heat pipe, under the effect of gravity, be back to the other end again, move in circles, realize heat exchange from an end.The shortcoming of above-mentioned heat exchanger is that heat transfer coefficient is low, and the ability of transfer of heat is little.

The utility model content

It is little that the purpose of this utility model solves existing heat exchanger heat transfer coefficient exactly, and the problem that the transfer of heat ability is little provides a kind of high heat transfer coefficient, heat pipe heat exchanger that the transfer of heat ability is big.

The technical solution adopted in the utility model is: the heat pipe heat exchanger, it comprises hermetically sealed can and is positioned at several heat pipes of hermetically sealed can, be provided with dividing plate in the described hermetically sealed can, the epicoele and the cavity of resorption that hermetically sealed can are divided into do not communicate, epicoele is provided with water inlet and vapor outlet, and cavity of resorption is provided with gas approach and exhanst gas outlet; Several heat pipes are applied in respectively on the dividing plate, make heat pipe top place the interior lower part of epicoele to place in the cavity of resorption; It is characterized in that described heat pipe comprises shell, capillary wick and is adsorbed on liquid medium in the capillary wick, heat pipe is a sealed tube, and inside is vacuum, and capillary wick is attached on the heat pipe inwall, middlely is the mobile cavity of steam.

Adopt technique scheme, during use, high-temperature flue gas is inserted from the cavity of resorption gas approach, discharge from exhanst gas outlet, epicoele water inlet and water source join, and vapor outlet inserts the vapour net.After high-temperature flue gas enters, the heat pipe that is arranged in cavity of resorption will absorb the heat of flue gas, the tube wall that heat passes shell heats up the liquid medium in the capillary wick, when liquid medium reaches vapourizing temperature, liquid medium will be vaporized into steam, rise along cavity, arrival is positioned at the heat pipe section of epicoele, being subjected to cooling makes the steam condensation become liquid, liquid is auspicious to be back to the part that heat pipe is positioned at cavity of resorption under the effect of capillary force in capillary wick, circulation continuously reaches the other end with heat from an end so repeatedly.

For further increasing heat transfer coefficient, the outside of described heat pipe is connected with several and is used for increasing the fin of inhaling the heat release area.

In sum, the beneficial effects of the utility model are: because Heat Transfer of Heat Pipe on Heat Pipe is to utilize heat pipe inner fluid collection attitude to change to conduct heat, and heat is outside equipped with fin, so the heat transfer coefficient height; Owing to be to be undertaken in the heat pipe, therefore be far longer than mode, so the ability of transfer of heat is big by heat conduction, liquid flow by the mode that transmits latent heat; Because the utility model is simple in structure, parts are few, so cost is low; Heat pipe is member independently, can change separately during damage, need not produce parking, and is therefore safe and reliable, easy to maintenance.
