Description

[0001] The present invention relates to a cooling device using a thermoelectric element and a PCM,

The present invention relates to a cooling apparatus using a thermoelectric element and a PCM, and more particularly, to a thermoelectric element and a PCM capable of effectively discharging cool air by using a thermoelectric element and a PCM for indoor cooling, And a cooling apparatus using the PCM.

Generally, in order to create a cool indoor environment by lowering indoor temperature in hot weather in an enclosed space such as a building or a vehicle, a structure capable of discharging cold air for generating indoor air after generating cold air from indoor hot air And air conditioners of various types are installed and used.

In recent years, mechanical compression type refrigerants using CFC refrigerants have been used for lightweight, price, and efficiency reasons. This type of air conditioner has a structure in which evaporators, condensers, compressors, expansion valves, etc. are connected by pipes And is configured to exchange heat with indoor air as the refrigerant compresses and expands while being circulated through the pipe.

However, in the conventional air conditioner, the structure is complicated and there is a risk that the refrigerant leaks, and since the refrigerant leaks spontaneously as time elapses, the cost of supplementing the refrigerant every time is required and maintenance is troublesome. A compressor, a condenser, and the like are required, so that the volume of the facility is increased and the manufacturing cost is increased. In particular, refrigerants such as chlorofluorocarbons are used to regulate the use of refrigerant gas because they destroy the ozone layer of the earth and cause environmental pollution.

As a prior art disclosed to solve the above problems, Korean Patent No. 1173518 discloses a blower for blowing and blowing outside air; A casing having a hollow portion and formed with a plurality of air injection passages for communicating an inner circumferential surface and an outer circumferential surface, an intake passage space in which the intake is fixed to the inside and which communicates with the outside of the plurality of air injection passages of the intake, A cooling turbine rotatably provided in the hollow portion, the turbine blade being rotated by air injected through the air injection passage to cool the injected air and discharge it in an axial direction; A blowing pipe communicating the blower with the intake air distribution space; A cooling air discharge pipe for discharging the air cooled by the cooling turbine; A first heat exchanger provided in the blowing pipe for exchanging heat with external air sucked by the blower; A second heat exchanger provided in the blowing pipe to exchange heat with the cooling air discharged to the cooling air discharge pipe; A second high temperature air supply line, one end of which communicates with the blowing pipe and the other end of which communicates with the outlet end of the cooling air discharge pipe; And a temperature control valve provided in the second high-temperature air supply line. Accordingly, there is known a refrigerant-free air-cooling apparatus in which refrigerant is unnecessarily used.

However, the above-mentioned conventional technology has a problem that the cooling efficiency is remarkably lowered by simply cooling the air by only the blower and the cooling turbine, and the power consumption is large due to excessive use of the blower and the cooling turbine.

Therefore, recently, a cooling apparatus using a thermoelectric module that cools ambient air by an endothermic effect by a current is being developed.

Such a thermoelectric element is configured such that one side thereof absorbs heat and the other side thereof dissipates heat that is absorbed thereby to cool the air as the heat of ambient air is taken away.

However, in the case of a cooling apparatus using a conventional thermoelectric element, if the heat radiation is not smoothly performed from the heat radiation surface radiating the heat absorbed by the thermoelectric element, the heat absorption surface temperature of the thermoelectric element rapidly rises and the cooling operation for cooling the air is not performed There was a problem that a situation occurred.

Also, in the past, when water is circulated for cooling the heat absorbing surface of the thermoelectric element, water continuously contacts with the thermoelectric element and the temperature gradually rises. Therefore, the cooling efficiency for the heat absorbing surface is lowered and cooling of the thermoelectric element is not properly performed There is a problem that the overall cooling efficiency of the air conditioner is lowered.

That is, a sufficient amount of the heat insulating material is filled between the lower substrate 133 in the cooler 100a positioned symmetrically with respect to each other, so that the insulating layer 140 is formed.

As a material used as a heat insulating material of the heat insulating layer 140, a metal material having excellent thermal conductivity is used, and a porous structure is formed so that air can flow smoothly.

In other words, by constructing the present invention like the above-described other embodiments, it is possible to maximize the cooling efficiency by widening the contact surface area with the air introduced from the outside.

In the other embodiments described above, the same configuration as that of the above-described embodiment can be employed, so that detailed description is omitted.

In the cooling apparatus using the PCM and the thermoelectric element according to the present invention to which the rapid cooling system 200 is applied, the first embodiment differs from the first embodiment in that the first cooling unit 20 is divided into upper and lower sections And the cooler 100a and the rapid cooler 200 are separately partitioned and mounted in an inner space of the case 40. [

The case 40 is installed in the outer case 21 and has a side opening corresponding to the inlet fan 23 and the outlet fan 25 of the outer case 21.

Although not shown in the drawing, it is also possible to mount a fan on the open side of the case 40 in the same manner as the case 21 to allow air to flow.

The cooler 100a and the rapid cooler 200 are separately installed in the upper and lower spaces defined in the case 40, respectively. For example, when the cooler 100a is mounted on the lower side of the case 40, the rapid cooler 200 is mounted on the upper side of the case 40.

In another embodiment of the cooling apparatus using the thermoelectric element and the PCM according to the present invention to which the rapid cooling system 200 is applied, as shown in FIG. 10, in the cooling system of the second embodiment, The rapid cooler 200 is configured to be arrayed with the cooler 100a.

The rapid cooler 200 is arranged at a predetermined interval between a plurality of the coolers 100a mounted on the first cooler 20 at regular intervals in the lateral or longitudinal direction.

10 (a), when the coolers 100a are arranged at regular intervals in the vertical direction, the rapid coolers 200 are arranged in the vertical direction at regular intervals between the coolers 100a, 10B, when the coolers 100a are arranged at regular intervals in the lateral direction, the rapid coolers 200 are arranged and spaced apart from each other in the lateral direction at intervals between the coolers 100a .

That is, according to the present invention configured as in the above-described another embodiment, since the cold and hot temperatures are transmitted to the air faster than the coolers filled with the PCM, it is possible to provide cooler cool air in the early stage of cooling.

In the above-described other embodiment, the same configuration as that of the above-described one embodiment and / or the other embodiments can be employed, and detailed description thereof will be omitted.

While the preferred embodiments of the cooling apparatus using the thermoelectric element and the PCM according to the present invention have been described above, the present invention is not limited thereto, and various modifications may be made within the scope of the claims, specification and accompanying drawings. And this also falls within the scope of the present invention.
