In addition, an exhaust fan 800 is provided in the exhaust part C, and an air supply fan 850 is provided in the air supply part B to induce a smooth flow of air introduced and discharged. On the A) and inlet (D) side, filters 350 and 350 'are respectively installed to prevent foreign substances contained in the ventilated indoor air and the inflowing outdoor air from entering the heat exchanger 200, while the inlet D In order to prevent the low temperature outdoor air flows directly into the heat exchanger 200, the electric heater 900 is provided as a heating device.

Accordingly, when the exhaust fan 800 of the waste heat recovery ventilator is operated, indoor air flows into the ventilation unit A through the ventilation port 400 and passes various filters while passing through the filter 350. The exhaust air is discharged to the outside through the exhaust port 500 via the heat exchanger 200, and at the same time, the outdoor air is introduced through the inlet 600 by the operation of the air supply fan 850. (D) is introduced into the room through the air supply port (700) through the air supply unit (B) via the heat exchanger 200 in a state where various foreign substances are filtered while passing through the filter (350 '). In this process, the indoor air and the outdoor air passing through the heat exchanger 200 serve to exchange heat through the heat exchange plate.

However, the conventional ventilator provided in the above structure has a problem that the heat exchanger occupies most of the internal space, so that the overall size is excessively large and power consumption is excessively required due to the use of the electric heater 900.

To this end, the present invention is installed in the transverse diaphragm in the inner center and the main body and the air inlet and the air inlet, and the exhaust and inlet are respectively installed on one side and the other side, respectively, is installed in the longitudinal direction in the inner center of the body The heat exchanger is installed in the center of the diaphragm in the transverse direction at the inner center of the heat exchanger is installed in close contact with the diaphragm, and disposed in both sides of the heat exchanger to filter the foreign matter contained in the ventilated indoor air and the incoming outdoor air In the ventilator is configured to include a filter and a bi-directional fan accommodated in each of the space separated by the diaphragm to allow selective adjustment of the ventilator according to the season and the indoor environment, the heat exchanger is heat Arrange the pipe in an inclined manner, and place the heat absorbing fin side of the heat pipe containing the refrigerant close to the horizontal. At the same time, the heat dissipation fin side opposite to the heat absorbing fin is positioned relatively high to enable gravity movement of the refrigerant, and the heat absorbing fin and the heat dissipation fin are formed in the left and right spaces of the heat pipe secured by the inclined structure, respectively. It is an object of the present invention to provide a series of ventilation devices characterized in that the area can be enlarged.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention, the ventilator in detail as follows.

According to the present invention, a diaphragm 11 in a transverse direction is installed at an inner center, and a main body (20A) and an air supply port (20D), and an exhaust port (20B) and an inlet port (20C) are installed at one side and the other side, respectively. 10) and both sides of the center of the diaphragm 11 which is installed in the longitudinal direction in the inner center of the main body 10 and is installed in the transverse direction in the inner center of the main body 10 in close contact with the diaphragm 11 On the heat exchanger (30), the filter (40), which is disposed on both sides of the heat exchanger (30) and installed to filter out foreign substances contained in the ventilated indoor air and the introduced outdoor air, and the diaphragm (11). It is characterized in that it is configured to include a bi-directional fan 50 accommodated in the separated space by each to enable selective adjustment of the ventilation device according to the season and the indoor environment.

The heat exchanger 30 applied to the present invention has a plurality of heat pipes 32 having a refrigerant for heat exchange therein as in a known general structure, and heat pipes for fixing and blocking the air pipes 32. Opposite side of the heat sink fin (33) and the heat sink fin (33) which are provided in the compartment 31 is installed in the center of the 32, the heat pipe (32) on which the refrigerant is accommodated based on the compartment 31. The heat dissipation fin 34 is installed on the heat pipe 32.

However, in the present invention, the heat pipe 32 is disposed to be inclined, while the heat absorbing fin 33 side of the heat pipe 32 in which the refrigerant is accommodated is positioned close to the horizontal and at the same time, the heat dissipating fins opposite to the heat absorbing fin 33 ( 34 is positioned relatively high to enable gravity movement of the refrigerant, and the heat absorbing fin 33 and the heat dissipating fin 34 are formed to extend in the left and right spaces of the heat pipe 32 secured by the inclined structure, respectively. By increasing the heat absorption and heat dissipation area.

The heat pipe 32 is preferably installed at an angle (A) of 10 to 45 degrees in consideration of the control of the heat dissipation area of the heat absorbing fins 33 and the heat dissipation fins 34 while smoothing the gravity movement of the contained refrigerant. The heat pipe 32 applied to the invention heat exchanger 30 excludes a bar type and applies a loop type having better heat exchange ability.

The present invention focuses on providing a ventilation device suitable for a situation in which a ventilation device is to be used efficiently or when a ventilation device is to be installed in an extremely limited space.

The slim ventilator of the present invention overcomes the limitations of the installation space while maintaining the ventilation performance as compared to the conventional ventilator. In the case of the heat exchanger 30, one side of the ventilator may return the condensed refrigerant to its original position. Left or right) is slightly lower and the other side is slightly higher.

Of course, the lower slope is where the refrigerant that absorbs the surrounding heat is evaporated, while the higher slope is where the refrigerant in the vapor state is condensed and released into the liquid state by releasing heat to the surroundings, and at the same time, the refrigerant is changed into liquid. Is naturally gathered down along the slope of the inclined heat pipe (32).

As described above, the lower side of the heat exchanger 30 is a bidirectional fan whose rotational direction is freely adjustable so as to allow suction or discharge of a fan that sucks and discharges air so that air at a higher temperature always flows. 50 is used, which completely eliminates the hassle of changing the position of the heat exchanger 30 or changing the heat exchanger 30 itself according to the season. In addition, the filter 40 for removing the dust contained in the air is also essential.

In the operation of the present invention, as shown in FIG. 1 showing the summer operation state, the air having a higher temperature must pass to the portion of the heat pipe 32 of the heat exchanger 30 having a lower slope. Therefore, in the summer, the outdoor hot air passes to the lower part and the indoor cool air is discharged to the upper part.

To this end, among the two bidirectional fans 50 installed, the bidirectional fan 50 mounted below in the drawing sets the rotational direction of the propeller so as to suck air, and the bidirectional fan 50 mounted above discharges indoor air to the outdoors. When the rotation direction of the propeller is set so that the air sucked into the lower portion of the heat pipe 32 from the outside is high in temperature, the temperature of the heat pipe 32 is increased, and the heat pipe 32 is heated by the high temperature. At the same time, the refrigerant evaporates and absorbs heat around the heat pipe 32 to lower the temperature of the air supplied to the room so that low temperature air can be supplied to the room.

On the other hand, the refrigerant evaporated as described above is immediately delivered to the upper portion of the heat pipe 32 and condensed by the cool air circulated and discharged from the room to emit heat to the surroundings, which is the heat pipe of the heat exchanger 30 (32) By increasing the temperature, the temperature of the air discharged from the room to the outside is increased.

The above process takes the heat of the air sucked from the outside and discharges it out again through the cool air discharged from the room, thereby lowering the temperature of the air sucked from the outside.

On the contrary, in winter, as shown in FIG. 2, the indoor warm air is discharged to the lower portion of the heat pipe 32 and the outdoor cold air is sucked to the upper portion of the heat pipe 32. The warm air discharged by the heat evaporates the refrigerant inside the heat conduction plate to absorb the surrounding heat and consequently absorbs the heat of the air discharged to the outside, and the evaporated refrigerant instantly heats up the heat exchanger 30. The upper part of the pipe 32 is condensed by the cold air sucked from the outside to dissipate heat to the surroundings, and at the same time, the emitted heat increases the temperature of the air sucked into the room from the outside to warm the heat discharged from the room. The heat absorbed from the air can increase the temperature of the cold air sucked outdoors.

In the above described and illustrated with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment without departing from the gist of the present invention claimed in the claims and having ordinary skill in the art Anyone can make various modifications as well as such changes are within the scope of the appended claims.

The present invention can overcome the limitations of the installation space as well as the selective adjustment and use of the ventilation device according to the season and the indoor environment, and the heat contained in one side of the refrigerant received through the heat pipe containing the refrigerant (冷媒) As the heat exchanger is configured in a horizontal form to transfer the heat transfer to the other part, the heat dissipation area can be expanded and the circulation of the refrigerant can be smoothly circulated by gravity, which is a very useful invention that can maximize the heat exchange performance of the ventilator.
