Summary of the invention

Problem to be solved in the utility model is the deficiency overcoming prior art existence, be provided for the fin heat pipe heat exchanger of a kind of drying tower that supporting grain drying tower uses, heat-conducting work medium in its fin heat pipe pipe is subject to the energy heats of heat pipe and phase transformation of vaporizing, phase-changeable gas carries out quick heat exchange, heat conduction by the tube wall of fin heat pipe and radiating fin, its heat exchange area increases 5-30 doubly, expand heat conduction heat exchange amount, improve heat conduction heat transfer rate.

In order to arrive above-mentioned purpose, the utility model is achieved through the following technical solutions: a kind of fin heat pipe heat exchanger of drying tower is made up of heat pipe and fin heat pipe, the fin one end that do not have of fin heat pipe is injected in heat pipe, and fin heat pipe becomes the angle of 20 °-90 ° to be connected and fixed to be integrated with heat pipe.

Described heat pipe is communicated with heating system; The heat energy of heating system carrys out heat conduction by the heat-carrying conductive fluid in heat pipe, heat pipe can add a hot recycle pump, accelerates the flowing velocity of conductive fluid like this, and heat conduction heat transfer effect can be better.

Described fin heat pipe is made up of vacuum tube, fin, heat-conducting work medium;

Described vacuum tube is metal sealing device, and the thickness of its tube wall, tightness need to arrive withstand voltage, the gastight requirement of vacuum;

1, vacuum tube is metal tube, and the two ends up and down of metal tube are end socket sealings; The cross section of vacuum tube is toroidal.

Heat-conducting work medium is had in the inner chamber of 2, vacuum tube;

3, the pipe thickness of vacuum tube will arrive withstand voltage, the gastight requirement of vacuum;

Described heat-conducting work medium is sealed in vacuum tube; The intraductal atmospheric pressure of vacuum tube requires according to the difference of gasification temperature the negative pressure pressure that setting is different, after also needing the gasification vapo(u)rous degree in design con-trol vacuum tube, adds corresponding appropriate heat-conducting work medium; Heat-conducting work medium is water, or acetone, or the working medium such as ethanol.

There is fin above the upper end tube wall of described vacuum tube, for increasing heat exchange area, improve heat conduction, heat transfer rate;

1, fin and vacuum tube are connected and fixed and are integrated, and can be longitudinal shape according to different requirement connection status, or transverse shapes, or around shape;

2, different according to dried material, the spacing between fin and fin is 2-50mm.

The utility model has following beneficial effect compared with existing heat abstractor: a kind of fin heat pipe heat exchanger of drying tower contacts fully with the material of drying tower inside, can directly to material, air heat-exchange heating; Its thermal energy conversion efficiency is high, and when the space of formed objects, volume, area of dissipation adds 8-30 doubly, and be conducive to thermal energy conduction heat exchange, expand the heat transfer rate of heat energy, heat energy is well changed, energy-conserving and environment-protective.
