Abstract

The invention discloses a radiator of a grain drying tower. The radiator of the grain drying tower is composed of heat pipes and a heat conducting pipe. One end of each heat pipe is inserted in the heat conducting pipe. The heat pipes and the heat conducting pipes are integrally fixed in a sealed mode in the vertical direction, and the angle between each heat pipe and the heat conducting pipe is 45-90 degrees. Each heat pipe is composed of a vacuum pipe and heat-conducting working media. Heat is continuously conducted to the bottom ends of the heat pipes by means of heat energy conducting liquid through the heat conducting pipe, so that the bottom ends of the heat pipes are heated continuously, and the heat conducting working media in the heat pipes can be subjected to phase change and evaporation continuously. Due to the fact that the pipe walls of the vacuum pipes are used for heat conduction and heat dissipation, the radiator of the grain drying tower can be used for heat conduction and heat dissipation continuously; the radiator of the grain drying tower makes full contact with grain in the grain drying tower, so that heat is directly conducted to the grain, and the grain is directly heated; the heat energy conversion rate of the radiator is high, the heat dissipation speed is increased by 1.5-3 times under the same space condition, heat energy conduction is facilitated, and heat energy is well converted; energy is saved, and environmental friendliness is achieved.

Description

The radiator of grain drying tower

Technical field

What the present invention relates to is a kind of radiator, specifically a kind of radiator of grain drying tower.

Background technology

Hot pipe technique is the heat transfer element that the one of the G.M.Grover invention of LosAlamos National Laboratory of the U.S. in 1963 is called " heat pipe ", it takes full advantage of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, be delivered to rapidly outside thermal source by the heat of thermal objects through heat pipe, its capacity of heat transmission exceedes the capacity of heat transmission of any known metal.

Now the heat energy of grain drying tower is commercially all tower external heat exchanger heat exchange, heat dissipation equipment in tower carries out heat radiation heating with calandria, but their radiator volume is large, area of dissipation is little, heat transfer efficiency is low, heat energy loss in heat transfer process is large, and the power of transporting heat energy also needs very high-power.

Summary of the invention

The problem to be solved in the present invention is the deficiency overcoming prior art existence, a kind of radiator of grain drying tower is provided, working medium in heat pipe is subject to energy heats and phase transformation is gasified, and gas carries out quick conductive heat radiation by the tube wall of vacuum tube, improves heat conduction and heat radiation speed.

In order to arrive above-mentioned purpose, the present invention is achieved through the following technical solutions: a kind of radiator of grain drying tower is made up of heat pipe and heat pipe, heat pipe one end is injected in heat pipe, and the angle fixing seal of heat pipe and upper and lower 45 °-90 ° of heat pipe is integrated.

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

1, vacuum tube is metal tube, and the two ends up and down of metal tube are end socket sealings;

2, heat-conducting work medium is had in vacuum pipe inner cavity;

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

4, the cross section of vacuum tube is triangle or toroidal or square shape.

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.

Described heat pipe is communicated with heating system; The high-temperature heat-conductive liquid that the heat energy of heating system or UTILIZATION OF VESIDUAL HEAT IN produce carrys out heat conduction by heat pipe.1, also can add a hot recycle pump in the middle of heat pipe, accelerate the velocity of liquid assets of conductive fluid like this, heat radiation, heat-conducting effect can be better; 2, conductive fluid is water or conduction oil.

The present invention has following beneficial effect compared with existing heat abstractor: a kind of radiator of grain drying tower contacts fully with the grain of grain drying tower inside, can heat directly to grain heat conduction; Its thermal energy conversion efficiency is high, and when the space of formed objects, radiating rate adds 1.5-3 doubly, and be conducive to thermal energy conduction, heat energy is well changed, energy-conserving and environment-protective.

Accompanying drawing illustrates:

Fig. 1, structural representation for the radiator of grain drying tower of the present invention;

Fig. 2, heat pipe structure schematic diagram for the radiator of grain drying tower of the present invention.

Specifically execute mode:

Below in conjunction with drawings and Examples, the present invention is described further.

Embodiment:

As shown in Figure 1: the radiator of grain drying tower is made up of heat pipe (1) and heat pipe (2), heat pipe (1) one end is injected in heat pipe (2), and heat pipe (1) is integrated with the angle fixing seal of upper and lower 45 °-90 ° of heat pipe (2).

As shown in Figure 2: heat pipe (1) is made up of vacuum tube (4) and heat-conducting work medium (3);

1, vacuum tube (4) is metal tube, and the two ends up and down of metal tube are end socket fixing seals;

2, heat-conducting work medium (3) is had in vacuum tube (4) inner chamber;

3, the cross section of vacuum tube (4) is toroidal;

4, heat-conducting work medium (3) is water.

Described heat pipe (2) is for being communicated with heating system.

When the radiator of grain drying tower works: be full of heat energy conductive fluid by heat pipe (2) to the ceaselessly heat conduction heating of the bottom of heat pipe (1), heat-conducting work medium (3) in heat pipe (1) just can ceaselessly be vaporized in phase transformation, come heat conduction, heat radiation by the tube wall of vacuum tube (4), the radiator of such grain drying tower just can ceaselessly heat conduction and heat radiation work.

Above embodiment just understands preparation method of the present invention and core concept thereof for helping; concrete enforcement is not limited to above-mentioned concrete embodiment, those skilled in the art from above-mentioned design, without performing creative labour; done change, all drops on protection scope of the present invention.
