Description

Cooling fan using thermoelectric element {COOL FAN}

The present invention relates to a cold air conditioner, and in particular, to provide a cold air blower using a thermoelectric element that cools a room by reducing air at room temperature to an appropriate temperature only by an electric means.

Typical cold air (cooling) units used in summer generally include air conditioners, fans, and ice coolers.

The air conditioner is divided into an indoor unit that provides cold air and an outdoor unit that reduces the temperature of the refrigerant, and it is difficult to manufacture a complicated structure in which devices such as a compressor, a condenser, and an evaporator are interconnected for cooling, and space utilization is reduced. There was a problem.

In addition, as the cooling capacity is larger, there is a problem that a very high noise is generated in the outdoor unit.

And refrigerants such as Freon used for cooling is a source of pollution that requires attention to destroy the environment.

The fan is a cooling mechanism that lowers the temperature as the evaporative heat that moves heat or generates moisture by forcibly circulating air around the human body, and does not have a cooling ability, and thus does not exhibit a re-function when the ambient temperature is high and the ambient humidity is high. Since the evaporation heat is not easily generated, it does not lower the temperature of the human body and thus does not show any effect to the user.

The ice cooler has the disadvantages of the fan, that is, the ice cooler using the ice developed for the purpose of securing the cooling action, there is a hassle to constantly replenish the ice, resulting in a humidification which is the opposite of the dehumidification. Moisture generated by evaporation of ice in summer with high humidity not only increases the user's discomfort index, but also causes the cooling space to be damp, thereby reducing the comfort level.

Accordingly, the present invention is based on a simple mechanical configuration, and aims to provide a cold air blower using a thermoelectric element that allows not only cooling but also dehumidification by electric means without noise and environmental pollution.

In order to achieve the above object, the present invention provides a left / right plate attached to each surface of a heat sink formed so that air flows up and down, and a thermoelectric element installed in close contact with both sides between the left / right plate; The left and right plates are attached to the inner center portion, the case is formed in the discharge chamber and the suction port in the front chamber and the rear chamber where the internal space is divided, each fan motor through which the air flows through the heat sink to the discharge port, and the fan motor And it provides a cold air blower using a thermoelectric element composed of a controller for applying and controlling the DC power to the thermoelectric element.

Accordingly, the present invention will be described in detail with reference to the accompanying drawings 1, 2, 3, 4 as shown in the configuration and the embodiment.

1 is a front view of the case 101 according to the present invention, Figure 2 is a rear view of the case 101 according to the present invention, Figure 3 is a side view of the case 101 showing a cooling device according to the present invention, 4 is an exploded perspective view of a heat sink and a left / right plate and a thermoelectric device according to the present invention.

Looking at the configuration of the present invention in detail with reference to such drawings, the heat sink 104 formed to distribute the air up and down, the left / right plate 102, 103 attached to each surface and the left / right plate A thermoelectric element 105 provided with both surfaces closely contacted between the 102 and 103, and the front and rear chambers 109 where the left and right plates 102 and 103 are attached to the inner center and the interior space is divided into two parts. A case 101 having discharge ports 107, 107 ′, suction ports 106, and 106 ′ formed in the rear chamber 110, and a discharge port passing through the heat sink 104 from the suction ports 106 and 106 ′. And a fan 111 for allowing air to flow to 107 and 107 ', and a controller 111 for applying and controlling DC power to the fan motor 108 and the thermoelectric element 105. .

The thermoelectric element 105 absorbs heat energy from the heat absorbing portion of one surface by a Peltier effect when the current passes in one direction, and emits heat energy from the heat generating portion of the other surface, so that the left / right plate ( 102 and 103 and the heat sink 104 are made of a good thermal conductivity aluminum material, and the heat sink 104, 104 'is injection-molded in a shape that passes through the regular valleys and the direction in which the valley proceeds And the direction in which air flows.

The left and right plates 102 and 103 block heat transfer between metals through a heat insulating material at a portion in contact with the case 101. In this way, the heat exchange between the heat generating portion and the heat absorbing portion should be prevented so that the efficiency of heat generation and endotherm decreases. For this purpose, the mounting bolts for fixing the left and right plates 102 and 103 to the case 101 are preferably made of a synthetic resin material.

The fan motor 108 is an inlet 106 'and a front chamber of the rear chamber 110 such that air flows from the inlets 106 and 106' to the outlets 107 and 107 'through the heat sink 104. 109 are attached to the suction port 106 and the discharge port 107, respectively.

At this time, the fan motor 108 mounted on the discharge port 107 of the front chamber 109 is preferably a blower fan.

The thermoelectric element 105 and the fan motor 108 are supplied with the appropriate DC power by the controller 111, and the fan motor 108 changes the applied voltage so that the rotation speed thereof is changed so that the front chamber 109 and The temperature of the air discharged from the rear chamber 110 is adjusted.

Alternatively, the amount of heat discharged from the front chamber 109 and the rear chamber 110 may be adjusted by increasing the number of thermoelectric elements 105 or increasing the capacity thereof to improve the exothermic energy and the endothermic energy.

Looking at the embodiment according to the operation of the present invention configured as described above are as follows.

First, when a predetermined DC power is applied to each of the thermoelectric elements 105 and the fan motor 108 through the controller 111, an endothermic reaction occurs on one surface of the thermoelectric element 105 in close contact with the right plate 103. When this endothermic reaction occurs in the right plate 103 and the heat sink 104 after a while due to thermal conductivity, the air introduced into the front chamber 109 through the inlet 106 by the fan motor 108 is lowered. While passing through the heat sink 104 to the upper side, the heat retained by the heat sink 104 is subtracted and converted into cold.

Therefore, such cool air is discharged to the room through the discharge port 107 by the fan motor 108 to cool the room temperature to a comfortable temperature as a good night.

An endothermic reaction occurs on one surface of the thermoelectric element 105 and an exothermic reaction occurs on the other surface of the thermoelectric element 105 in close contact with the left plate 102.

The heat energy generated by the exothermic reaction discharges the heat energy generated by the thermoelectric element 105 while the air introduced into the rear chamber 110 through the suction port 106 'by the fan motor 108 passes through the heat sink 104. 107 'to release to the outside.

In this way, the indoor air is introduced into and discharged into the rear chamber 110, and a dehumidifying action is performed to reduce humidity in the air of the indoor space.

5 and 6, the shapes of the heat sink 104 and the discharge port 107 ′ of the rear chamber 110 may be modified.

That is, the heat dissipation plate 104 'allows the flow of air to flow from side to side, whereby the position of the discharge port 107' is formed to facilitate the discharge of air to the left and right sides of the rear chamber 110.

As described above, the present invention is based on a simple mechanical configuration using a thermoelectric element, cooling as well as a dehumidification effect is made, there is an effect of reducing the noise generated during the cooling operation, and the refrigerant is electrically controlled By means, it has an environmentally friendly effect.

And, since the cooling and dehumidification is made at the same time, there is an effect of improving the comfort during cooling.
