Description

VENTILATION DEVICE FOR WINDOWS WITH HEAT PIPE

The present invention relates to a ventialtion device, and particularly to a ventilation device for windows with a heat pipe, which is installed in a window frame so as to discharge indoor air to an outdoor space and introduce outdoor air into an indoor space and also to exchange heat between the indoor air and the outdoor air, wherein the heat pipe is diposed at a partition wall, through which the indoor and outdoor air is passed, so as to perform further heat exchange therebetween.

Generally, a carbon dioxide content in indoor air is gradually increased due to breathing of living things, as time passes. And since the increased carbon dioxide content inhibits the breathing of living things, it is necessary to frequently replace the indoor air with fresh air.

Typically, indoor air is forcibly discharged to an outdorr space by a ventilation device such as an air blower, and outdoor air is naturally introduced through an opened window into an indoor space. However, if the indoor air is relaced in such way, it is impossible to achieve total heat exchange between the indoor air and the outdoor air. Thus, there are some problems in that unnecessary expense for air conditioning and heating of the indoor space is required and also persons in the building may have an unpleasant feeling due to a rapid change in temperature. Herein, the total heat exchange includes sensible heat exchange meaning temperateure exchaneg, and latent heat exchange meaning humidity exchange.

To solve the problems, there is disclosed a window type ventilation device in Korean Patent Laid-Open No.10-2008-89001 (hereinafter, called as "first reference"). The window type ventilation device declosed in the first reference is disposed in a mullion of a window frame and also includes a cross-flow fan and a heat exchanger. The cross-flow fan functions to introduce outdoor air through an upper portion of the mullion into an indoor space and also to discharge indoor air through a lower protion of the mullion to an outdoor space. The heat exchanger receives a heat exchange medium such as ethylene glycol and glycerin glycol and extends along a extension direction of the mullion. Heat exchange between the introduced air and the discharged air is carried out by up and down reciprocating movement of the heat exchange medium.

Further, to solve the above-mentioned problem, there is disclosed a window equipped with a ventilation device in Korean Patent Laid-Open No.10-2004-75686 (hereinafter, called as "second reference"). The window equipped with the ventilation device declosed in the second reference includes a case which is disposed in a transom of a window frame. The case includes a first fan which discharges indoor air to an outdoor space, a second fan which introduces outdoor air into an indoor space, a partition wall which prevents the outdoor air introduced from the outdoor space and the indoor air discharaged to the outdoor space from being mixed with each other, and a heat exchanger which performs heat exchange between the outdoor air and the indoor air. The heat exchanger includes a fin type heat exchanger and a plate type heat exchanger in which a plurality of plates are stacted.

An object of the present invention is to provide a heat exchange means which can perform the heat exchange between air discharged from an indoor space to an outdoor space and air introduced from the outdoor space into the indoor space, and at the same time, which can more efficiently perform the heat exchange.

To achieve the object of the present invention, the present invention provides a ventilation device for windows, including a heat exchange module which is disposed at a window frame of a divided window so as to allow heat exchange between air introduced from an outdoor space and air introduced from an indoor air without mixture therebetween; and an exhaust module which is disposed at the window frame so as to be adjacent to the heat exchange module, wherein a heat pipe is provided at a partition wall which is disposed in the heat exchange module so as to separte indoor air and outdoor air from each other, thereby achieving the heat exchange between the indoor air and the outdoor air.

Preferably, the heat exchange module is provided with a heat exchange device for performing heat exchaneg between the indoor air and the outdoor air, and the partition wall separates the indoor air and the outdoor air from each other before the indoor air and the outdoor air is introduced into the heat exchange module.

Preferably, the heat pipe is formed into a pipe which receives liquid having a low evaporating temperature therein, and one end of the heat pipe is located at one space in which the indoor air or the outdoor air is introduced, and the other end thereof is located at the other space.

Preferably, the other end of the heat pipd is provided with a heat radition plate.

Preferably, the partition wall is formed at a fan cover that receives an outdoor air fan and an indoor air fan, and also used as a separation wall for preventing the indoor air and the outdoor air from being mixed with each other in the fan cover.

Preferably, one end of the heat pipe is provided with a curved heat radiation plate.

Preferably, the heat exchange module purifies the introduced indoor and outdoor air before the indoor and outdoor air is introduced into the heat exchange device. And the exhaust module is provided so that the outdoor air is discharged at mulitple points arranged along a length of the exhaust module, and the multiple points are formed over the entire length of the exhaust module.

Preferably, the ventilation device further includes a connection module which is disposed at the window frame so as to receive the outdoor air from the heat exchange module and then transfer the outdoor air to the exhaust module.

Hereinafter, the embodiments of the present invention will be described in detail with reference to accompanying drawings. The terms and words used in the description as described below are not limited to the typical or dictionary definition, and they can be interpreted as proper meanings and definitions cosistent with the technical ideas.

As shown in Fig. 1, a ventilation device for windows of the present invention includes a heat exchange module 200 which is disposed in a left transom, a right transom or left and right transoms 110 of a divided window, an exhaust module 400 which disposed in a center transom 140 of the divided window, and a connection module 600 which connects the heat exchange module and the exhaust module 400.

As shown in Fig. 2, the heat exchange module 200 includes a heat exchange unit 210 and a cover 250.

As shown in Fig. 3a, the heat exchange unit 210 includes a case 212, and an outdoor air filter 222, an indoor air filter 224, a

heat exchange device

226, 228, an indoor air fan 236, an outdoor air fan 238 and a fan cover 230 which are respectively received in the case 212.

At side surfaces of the case 212, there are formed an outdoor air introduction duct 214 for introducing outdoor air into the case 212, an outdoor air discharge duct 220 for discharging the introduced outdoor air to an outside of the case 212 and an indoor air discharge duct 218 for discharging indoor air to an outside of the case 212. Further, at a lower surface of the case 212, there are formed an indoor air inroduction hole 216 (referring to Figs. 5 to 7) for introducing the indoor air into the case 212 and a door (not shown) which is opened/closed or removable so as to facilely replace the outdoor air filter 222, the indoor air filter 224 and the heat exchange device 226.

Meanwhile, as shown in Fig. 2, when the heat exchange unit 210 is disposed in the transom 110, the outdoor air introduction duct 214 and the indoor air discharge duct 218 are inserted into the transom 110, and the outdoor air discharge duct 220 is directed in a direction that the exhaust module 400 is located, and the indoor air introduction hole 216 is directed downward. If the indoor air introduction hole 216 is directed downward, it is possible to prevent foreign substances such as floating dusts from being introduced throught the indoor air introduction hole 216 into the case 212.

The outdoor air filter 222 is to purify the outdoor air introduced into the case 212. Therefore, the outdoor air filter 222 is disposed so as to purify the outdoor air right after the outdoor air is introduced into the case 212 or just before the outdoor air is discharged to the outside of the case 212. However, if the outdoor air introduced into the case 212 directly passes through the

heat exchange device

226, 228, the

heat exchange device

226, 228 may be clogged. Thus, it is preferable that the the outdoor air filter 222 is disposed so as to purify the outdoor air right after the outdoor air is introduced into the case 212. In this case, as shown in Fig. 3a, the outdoor air filter 222 is disposed between the outdoor air introduction duct 214 and the first heat exchange device 226.

The indoor air filter 224 is to purify the indoor air introduced into the case 212. If the indoor air introduced into the case 212 directly passes through the

heat exchange device

226, 228, the

heat exchange device

226, 228 may be clogged. Thus, it is necessary to provide the indoor air filter 224. The indoor air filter 224 is disposed so as to purify the indoor air right after the indoor air is introduced into the case 212. That is, the indoor air filter 224 is disposed between the indoor air introduction hole 216 and the first heat exchange device 226.

The heat exchange device is to exchange heat or heat and humidity between the indoor air and the outdoor air introduced into the case 212. As shown in Figs. 3a and 4, the heat exchange device includes the first and second

heat exchange devices

226 and 228. Herein, the first and second

heat exchange devices

226 and 228 are disposed so that the indoor air and the outdoor air is not mixed in the case 212. In case that the two heat exchange devices are included in the case 212, the first and second

heat exchange devices

226 and 228 may be all sensible heat exchange devices or total heat exchange devices, or may be a combination of the heat exchange device and the total heat exchange device. Preferably, in order to ensure a sufficient heat exchange time, one 226 of the heat exchange devices is formed into a hexagonal pillar. However, the present invention is not limited to this embodiment. As shown in Fig. 6, all of the two heat exchange devices may be formed into square pillars. Further, the present invention is not limited to the two heat exchange devices. As shown in Fig. 7, the number of the total heat exchange devices may be one or, if necessary, three or more.

And the indoor air fan 236 is provided to introduce the indoor air into the indoor introduction hole 216 (referring to Fig. 5) and then discharge the indoor air through the indoor air discharge duct 218 to the outside of the case 212. The outdoor air fan 238 is provided to introduce the outdoor air through the outdoor air introduction duct 214 into the case 212 and then discharge the outdoor air through the outdoor air discharge duct 220 to the outside of the case 212. The fan cover 230 functions to cover the indoor air fan 236 and the outdoor air fan 238. As shown in Fig. 4, a separation wall 232 is formed at the fan cover 230 so as to prevent the outdoor air and the indoor air passed through the second heat exchange device 228 from being mixed with each other.

Meanwhile, as shown in Figs. 5 to 7, it is preferable that a guide wing 227 is disposed at the lower surface of the case 212. The guide wing 227 is disposed between the outdoor air filter 222 and the first heat exchange device 226 and between the first and second

heat exchange devices

226 and 228 so as to guide flow of the outdoor air and the indoor air. Further, the guide wing 227 having a desired height is formed into a circular arc shape which is protruded toward the side surface of the case 212.

When the indoor air fan 236 and the outdoor air fan 238 are operated, the outdoor air is introduced through the outdoor air introduction duct 214 into the case 212 and then introduced through the outdoor air filter 222 into the first heat exchange device 226, and the indoor air is introduced through the indoor air introduction hole 216 into the case 212 and then introduced through the indoor air filter 224 into the first heat exchange device 226. And then, after senbile heat exchange or total heat exchange between the indoor air and the outdoor air is carried out in the first heat exchange device 226 without mixture therebetween, the indoor air and the outdoor air is introduced into the second heat exchnge device 228. After the senbile heat exchange or total heat exchange between the indoor air and the outdoor air is carried out in the second heat exchange device 228 without mixture therebetween, the indoor air and the outdoor air is introduced into the fan cover 230. After that, the indoor air and the outdoor air is passed through the indoor air fan 236 and the outdoor air fan 238, and the indoor air is discharged through the indoor air discharage duct 218 to the outside of the case 212, and the outdoor air is discharged through the outdoor air discharge duct 220 to the outside of the case 212. In Figs. 3a, and 5 to 7, the flow of the outdoor air is designated by an unbroken line arrow, and the flow of the indoor air is designated by a broken line arrow.

The heat exchange between the indoor air and the outdoor air introduced into the case 212 is carried out in the

heat exchange device

226, 228. According to the present invention, the heat exchange is also performed in a partition wall.

More detailedly, referring to Fig. 3a, the indoor air is introduced into a first space S1 of the case 212, and the outdoor air is introduced into a second space S2 thereof. According to the present invention, a heat pipe (referring to 310 of Fig. 3b and 350 of Fig. 3c) is installed at a partition wall W formed between the first space S1 and the second space S2 so that the heat exchange can be also performed between the indoor air and the outdoor air of the first and second spaces S1 and S2. For the sake of convenience, the heat pipe is shown in Figs. 3b and 3c, but not in Fig. 3a.

Typically, the heat pipe is a pipe that air is removed and volatile liquid such as alcohol is put into an inside thereof having a plurality of small bores. The liquid has a low evaporating temperature. Thus, if one end of the pipe is heated, the liquid is evaporated by absorbing the heat energy and then flowed to the other end thereof. The absorbed heat of the liquid is radiated at the other end of the pipe and the liquid is then returned to its origianl position. The heat exchanged is occurred in such way. A shape of the heat pipe is not limited particularly, but it is generally formed into an elongated cylindrical pipe shape.

Fig. 3b shows the heat pipe 310 which is installed at the partition wall W according to one embodiment of the present invention. The heat pipe 310 is in the form of an elongated pipe, and liquid such as alcohol having a low evaporating temperature is received in an internal space 340 thereof. One end 320 of the heat pipe 310 is located at one of the first and second spaces S1 and S2, and the other end 330 thereof is located at the other one of the first and second spaces S1 and S2. In other words, the both ends 320 and 330 of the heat pipe 310 are respectively loacated at the internal spaces S1 and S2 which are separated by the partition wall W so that the indoor air and the outdoor air is received separately. Thus, the heat exchange is occurred between the internal spaces S1 and S2.

Fig. 3c shows the heat pipe 350 according to another embodiment of the present invention. Herein, the heat pipe 350 is formed into an elongated pipe, and liquid such as alcohol having a low evaporating temperature is received in an internal space thereof. One end 360 of the heat pipe 350 is located at one of the first and second spaces S1 and S2, and the other end 350 thereof is located at the other one of the first and second spaces S1 and S2. The other end of the heat pipe 350 has a plurality of heat radiation plates 370 so that the heat exchange is more facilely performed.

As described above, the heat pipe may be disposed at a position of the case 212, in which the indoor air and the outdoor air is introduced, so as to perform the heat exchange. However, the heat exchange may be performed at other position of the case 212, in which the indoor air and the outdoor air is introduced, by using the heat pipe. The heat pipe is also provided at the partition wall W of Figs. 5 to 7, but the description thereof will be omitted for the sake of convenience.

Referring to Fig. 4, as described above, the indoor air and the outdoor air passed through the second heat exchange device 228 is not mixed with each other in the fan cover 230 due to the separation wall 232. In the present invention, the

heat pipe

310, 350 may be disposed at the separation wall 232 so that the heat exchange is achieved between the indoor air and the outdoor air flowed at opposite sides of the separation wall 232. In this case, the heat pipe disposed at the separation wall 232 may have the same shape as the

heat pipe

310, 350. However, as shown in Fig. 4c, the heat pipe may have a heat radiation plate 390 having a curved shape, considering that the separation wall 232 is formed into a curved shape in order to receive the fan.

The cover 250 functions to cover the heat exchange unit 210 and includes an upper and side cover 252, a side cover 258 and a lower cover 256, as shown in Fig. 8. The upper and side cover 252 has an approximately 'ㄱ' shape in section, and a hook 253 coupled with the left and right transoms 110 is formed at an end of the upper and side cover 252. The side cover 258 has an approximately 'ㄴ' shape in section, and a hook 259 coupled with the left and right transoms 110 is formed at an end of the side cover 258. The lower cover 256 has a straight shape in section, and one end of the lower cover 256 is contacted with the side cover 258, and the other end there is formed with a hook 257 coupled with the upper and side cover 252. In this case, after removing the lower cover 256 and opening a door (not shown) formed at the lower surface of the case 212, a user can replace the outdoor air filter 222, the indoor air filter 224 and the total heat exchange device.

Meanwhile, as shown in Fig. 8, a shock absorbing member 254 is provided at an inner surface of the upper and side cover 252. The shock absorbing member 254 functions to protect the heat exchange unit 210 from physical shock imparted on the heat exchange module 200, and also to prevent noise generated from the indoor air fan 236 and the outdoor air fan 283 from being transferred to the indoor space.

Hereinafter, the left and right transoms 110 in which the heat exchange module 200 is disposed will be described with reference to Figs. 8 and 9.

A pair of hollow holes are formed at the left and right transoms 110, and a pair of ducts 112 are respectively inserted into the hollow holes. The pair of ducts 112 receives the outdoor air introduction duct 214 and the indoor air discharge duct 218, respectively. A flange 114 having a bolt hole 116 is formed at one end of the duct 112.

A girder 120 for supporting the heat exchange unit 210 is coupled to the flange 114. The girder 120 has an approximately 'ㄴ' shape and is also fixed to the flange 114 by a bolt 118. The bolt 118 is passed through the girder 120 and then inserted into the bolt hole 116. Herein, the girder 120 has a desired width so that the replacement of the outdoor air filter 222, the indoor air filter 224 and the total heat exchange device is not disturbed. A shock absorbing member 122 is provided at an inner surface of the girder 120. The shock absorbing member 122 functions to protect the heat exchange unit 210 from physical shock imparted on the heat exchange module 200, and also to prevent noise generated from the indoor air fan 236 and the outdoor air fan 283 from being transferred to the indoor space.

At an end of the duct 112 which is opposite to the flange 114, there is provided a hood 126 having an opening which is foremd donwnwardly. The hood 126 functions to prevent rain and snow from being introduced into the duct 112. Meanwhile, it is preferable that a net 128 is provided at the opening of the hood 126. The net 128 functions to prevent floating matters such as leaves from being introduced into the duct 112.

At the opening of the duct 112, which is located in a direction of the hood 126, there is provided a damper 124 which prevents strong wind from being entered into the indoor space. As shown in Figs. 8 and 9, the damper 124 is extended parallel to the duct 112 and then bent downwardly after getting out of the duct 112. If the string wind is entered from the outdoor space into the hood 126, the damper 124 is rotated by the wind, and thus the duct 112 is closed. After that, if wind strength is decreased, the damper 124 is rotated reversely by its own weight, and thus the duct 112 is opened.

The exhuast module 400 is to receive the outdoor air from the heat exchange unit 210 and then discharge the outdoor air to the indoor space. As shown in Figs. 10 to 13, the exhaust module 400 includes an upper member 410, a middle member 430 and a lower member 450.

The upper member 410 includes a hook 412 which is formed at an end of the upper member 410 so as to be coupled with the center transom 140, and a side surface 414 which is surface-contacted with the center transom 414.

The middle member 430 includes a hook 436 which is formed at an end of the middle member 430 so as to be coupled with the upper member 410. The middle member 430 is partially surface-contacted with the upper member 410. An outdoor air passage is formed by coupling the upper member 410 and the middle member 430. Further, the middle member 430 has a plurality of guiders 434 which are arranged in a length direcetion of the center transom 140 and extended in a direction perpendicular to the length direcetion of the center transom 140. An outdoor air discharage port 432 is formed between the guiders 434. A flow direction of the outdoor air which is moved through the outdoor air passage 402 in the length direction of the center transom 140 is changed by the guider 434, and then the outdoor air is introduced through the outdoor air discharge port 432 into the indoor space. Meanwhile, the outdoor air discharge port 432 is fomred over an entire length of the exhuast module 400.

The lower member 450 includes a hook 452 which is coupled with the middle member 430, a hook 454 which is coupled with the upper member 410 and an upper surface 456 which is surface-contacted with the center transom 140. The lower member 450 is fixed to the center transom 140 by a bolt 470.

As shown in Fig. 2, the connection module 600 includes a connection adaptor 620, a connection duct 610 and a cover 630. The connection adaptor 620 is to facilitate the connection with the exhaust module 400 and the connection duct 610. One end of the connection adaptor 620 is inserted into the outdoor air passage 402 of the exhaust module 400, and the other end thereof is inserted into the connection duct 610. The connection duct 610 is to transfer the outdoor air from the heat exchange module 200 to the exhaust module 600. One end of the connection duct 610 receives the other end of the connection adaptor 620, and the other end thereof receives the outdoor air discharge duct 220. A cover 630 is to cover the connection adaptor 620 and the connection duct 610, and removable disposed at the window frame.
