Description

Heat Pipe Type Cooling and Heating Panel {Heat Pipe Type Cooling / Heating Panel}

The present invention relates to a heat pipe type heating and cooling panel, and more particularly, to a heat pipe type heating and heating panel which can shorten the heating and cooling time and realize a uniform heating and cooling in heating and cooling.

In general, the air-conditioning system of a large building is a convection-type air-conditioning system using air as a medium to perform cooling or heating by forcibly circulating air, a heat transfer medium. However, such a convection heating and cooling system has a problem in that a lot of energy is consumed in the process of heating or cooling the air as a medium. In addition, when the air-conditioning system is operated for a long time or the air purification is neglected, the air may be contaminated by harmful substances and germs, and when it comes into contact with the polluted air, it is very unsanitary.

On the other hand, the air-conditioning system of a general house is a heating and cooling system using radiant heat to install a pipe on the floor and circulate the hot or cold water through the pipe, or heating and heating by installing a heating wire.

By the way, the cooling and heating system using radiant heat has a problem that the temperature distribution is not uniform at the initial stage of cooling and heating, and the cooling and heating time is delayed. In particular, since the dew condensation occurs due to a severe temperature difference with the cooling source when cooling, a dehumidification device is also required.

To solve this problem, a heating and heating pipe and heating wire were installed on the ceiling. This method allows heat transfer by radiation and convection during cooling, but it is less effective since heat transfer is possible only by radiation when heating. In addition, because of the heating and cooling method using a pipe and a heating wire, the problem of delayed cooling and heating time or nonuniform temperature distribution still remained.

In recent years, heat pipes with fast heat transfer have been applied to form a heating and cooling system. Heat pipe (heat pipe) is a device that transfers heat between the two ends of the vessel through the process of gas-liquid phase change continuously in the sealed container, by moving the heat using the latent heat (latent heat) It exhibits very high heat transfer performance compared to conventional heat transfer equipment using a working fluid.

By applying the heat pipe to the cooling and heating system as described above, the problem of delayed cooling and heating time and uneven temperature distribution have been solved to some extent, but they are not satisfactory and are somewhat insufficient to realize comfortable heating and cooling.

Accordingly, an object of the present invention is to provide a heat pipe type heating and cooling panel capable of shortening the air-conditioning time and achieving a uniform heating and cooling air-conditioning during heating and cooling. In addition, another object of the present invention is to provide a heat pipe type heating and cooling panel having low power consumption and excellent heat transfer efficiency.

The heat pipe type heating and cooling panel according to the present invention for achieving the above object is provided with a first panel body in which a plurality of conveying paths are formed, and provided in the lower portion of the first panel body and communicating with the conveying path, And a second panel body having a built-in means, and a working fluid filled in the second panel body.

At this time, the interior of the first panel body is partitioned into a plurality of transport paths by the corrugated material bent in a concave-convex shape. In addition, a small mesh is provided between the first panel body and the corrugated sheet. In addition, a heating coil, a heating cartridge, or a heat exchange tube capable of injecting cold water and hot water is used as the cooling and heating means.

In the heat pipe type heating and cooling panel according to the present invention configured as described above, when the air-conditioning means is operated, a phase-change working fluid moves along the transfer path and transfers heat to the outside.

The heat pipe type heating and cooling panel according to the present invention can shorten the heating and cooling time by operating the cooling and heating means as described above, changing the working fluid phase, moving along the transfer path, and transferring heat to the outside, and uniform temperature distribution during heating and cooling. It can realize comfortable air-conditioning.

In addition, since the cooling or heating by the heat pipe method, power consumption is low, heat transfer efficiency is excellent, and condensation does not occur because the temperature difference between the heat source or the cold source is small.

In addition, since the space (floor and ceiling) required for installing pipes and heating wires for heating and cooling is not required, the height of the building can be greatly reduced.

With reference to the accompanying drawings will be described an embodiment according to the present invention in detail. Hereinafter, in describing the embodiments according to the present invention, detailed descriptions of related known configurations or functions will be omitted. In addition, in adding the reference numerals to the components of each drawing, the same reference numerals are added to the same components as much as possible.

And the heat transfer amount ( Q ) can be obtained through [Equation 1] below.

Figure 112009500850247-utm00001

Where σ is the Stefan-Boltzmann radiant heat transfer constant, A is the heat transfer area, and T 1 and T 2 are the absolute temperature of the radiation plane and the subject's absolute temperature (K).
