The present invention relates to a dehumidification and cooling device for dehumidifying and cooling an inside of a box such as a switchgear or a control device, which is closed by means of an electronic cooling element using the Peltier effect, and also relates to a radiator used in such a device.

Originally, devices such as sealed switchboards and various types of control devices needed to prevent temperature rise and dew condensation in the device in order to ensure high reliability of the device. In this case, electronic cooling devices using the Peltier effect have been used.

1 and 2 show a conventional dehumidifier using this method. The cylindrical body 2 extending vertically in the box 1 has an inlet port 3 on its bottom surface and an exhaust port 4 on its top surface, and a vertically extending heat conductive plate fixed to the inside of the cylindrical body 2. 5).

At the lower end of the heat conduction plate 5, the electronic cooling element 6 has a heating or heat dissipation surface in contact with the heat conduction plate 5, thereby conducting heat to the heat conduction plate 5, and the heat absorbing fin 7 is an electron. The heat absorbing surface of the cooling element 6 is fitted. A heat dissipation fan 8 is fitted to the upper end of the heat conduction plate 5, a drip tray 9 is provided at the bottom of the cylindrical body 2, and a drain pipe 11 is provided at the drain port 10 of the drip tray 9. It is connected.

In addition, a transformer 12 for operating the electronic cooling element 6 is provided on the upper portion of the cylindrical body 2, and the insulating material 13 is an outer circumferential surface of the electronic cooling element 6 that thermally insulates the heat generating portion and the cooling portion from each other. Is provided.

When the electronic cooling element 6 is operated by the transformer 12, as the temperature of the heat absorbing surface of the electronic cooling element 6 is lowered, the temperature of the heat absorbing element 7 is lowered, and the heat generation of the electronic cooling element 6 is generated. As the surface temperature rises, the temperature of the heat dissipation fan 8 rises due to the heat conduction through the heat conduction plate. The upper air in the cylindrical body 2 is heated and expanded by heat generated from the heat radiating fan 8 and the transformer 12, and is then discharged through the exhaust port. As a result, the air in the box 1 flows into the cylindrical body 2 through the intake port 3, and the flow of circulating air resulting from natural convection occurs.

Eventually, the air flowing into the cylindrical body 2 is cooled by the endothermic fan 7 below the cylindrical body 2, and the steam contained in the air condenses to become water, and the water is received by the drip tray 9, It is discharged to the outside through drains and drains. The dehumidified air is dried and heated after being discharged by the heat radiating fan (8) and the transformer (12) above the cylindrical body (2). This operation may be repeated to dehumidify the box 1.

3 and 4 show another conventional cooling apparatus using an electronic cooling element.

The electronic cooling element 16 is disposed in the through hole formed in the outer wall of the box 14 via the insulating material 15, and the heat radiation fin 17 serving as a radiator is in contact with the heat generating surface of the electronic cooling element 16. It is provided outside the box 14. The external blower 18 is for forcibly cooling the heat dissipation fan 17. On the other hand, inside the box, an endothermic fan 19 is provided in contact with the endothermic surface of the electronic cooling element 16, and the internal blower 20 is provided for directing air in the box 14 to the endothermic fan 19.

Since the air in the box 14 flows toward the endothermic fan 19 by the internal blower 20, and the temperature of the endothermic fan 19 is lowered by the operation of the electronic cooling element 16, the air in the box 14 gradually increases. Is cooled. If the air in the box 14 contains a large amount of moisture, the moisture turns into dew bubbles and is removed from the air.

The air in the box 1 of the dehumidifier shown in FIGS. 1 and 2 of the above-mentioned conventional apparatus is cooled by an endothermic fan 7, and the moisture in the air condenses it to condense the condensed moisture in the box 1. It can be removed by discharging to the outside. However, since the radiating heat (8) and the radiating box (1) of the transformer 12 is radiated into the box 1, the inside of the box 1 is not completely cooled.

In the cooling apparatus shown in FIGS. 3 and 4, the heat absorbing fins 19 and the heat radiating fins 17 are provided on the inner and outer surfaces of the box 14, respectively, so that the inside of the box 14 can be cooled effectively. However, the water condensed in the endothermic shock (19) is not discharged to the outside of the box is not completely dehumidified. When a very efficient endothermic or cooling effect is required, the temperature difference between the heat absorbing surface and the heat generating surface needs to be set small in consideration of the characteristics of the electronic cooling element. As a result, when the temperature of the endothermic shock 19 increases, it becomes impossible to remove moisture.

Furthermore, as shown in FIGS. 3 and 4, the conventional apparatus is exposed to the heat radiation fan 17 and the external blower 18 installed outside the box 14, so that the high temperature heat radiation fan 17 and the rotary blower are exposed. There is a problem of safety. In addition, the heat radiation fan 17 may be damaged because the protection device is not provided.

The above-described problems of the conventional apparatus can be solved by covering the heat dissipation fan 17 and the external blower 18 with the cover 100 indicated by dashed lines of FIGS. 3 and 4. However, in this case, since the cover 100 is required as the separating part, the apparatus is expensive and the size of the radiator is large.

The present invention has been practiced to solve this problem in view of the above-described problems. A first object of the present invention is to provide a dehumidification and cooling device using an electronic cooling element capable of dehumidifying and cooling the inside of a box, and a second object is to provide a radiator which may act as a casing having a decorative appearance.

It may be formed. In this case, the heat dissipation area is increased, and the heat dissipation capability of the radiator 23 is significantly improved.

In Fig. 5, reference numeral 25 denotes a heat dissipation blower which is an axial blower accommodated in the blower cover 24 'by being directly screwed under the radiator 23. The heat radiating blower 25 sends the outside air of the box 21 to the space formed in the concave portion 23c of the radiator 23 from the bottom to forcibly cools the air of the radiator 23. Reference numeral 26 designates a ventilation guide.

The thermal insulation thin plate 27 has two rectangular holes for attaching the electronic cooling element 28. The two electronic cooling elements 28 using the Peltier effect are disposed in the through-holes 22 together with the heat insulating thin plates 27 in combination with the rectangular holes of the heat insulating thin plates 27 and at the same time, the two electronic cooling elements 28 are used. Each of the heat generating portions on the rear surface is in contact with the substrate 23a.

The heat absorbing fin 29 located in the box 21 has a plurality of vertically extending fins, and the substrate (not shown) is screwed in such a manner that two electronic cooling elements 28 are sandwiched between the sink 23a and the heat absorbing fin 29. Fixed to 23a). The screw 30 for attaching the heat absorbing fin 29 is insulated from the heat of the heat absorbing fin 29 by a heat insulating sheet 31.

The cover 32 has an inlet 33 on its upper surface and an exhaust port 34 on its left and right sides. The cover 32 has a contraction portion 35 formed by pressing the front side of the cover backwards just above the endothermic fan 29, and the contraction part concentrates the air from the intake blower 36 toward the endothermic fan 29. To guide.

An intake blower 36, which is an axial blower, is used to fix the substrate 23a via the heat insulating thin plate 27, located on the top of the cover 32. The intake blower 36 sucks air in the box 21 through the inlet 33 and supplies it into the cover 32, and sends it to the endothermic fan 29 provided below the intake blower 36.

The inclined surface 39 and the inclined surface 39 are provided in the bottom surface of the cover 32 in the position which connects with the right wall of the cover 32, and the drain port 40 is provided. The drain pipe 41 connected to the drain hole 40 passes through the outer wall of the box 21 to the outside.

The heat absorbing heat 29 has the same size or volume as the heat absorbing surface of the electronic cooling element 28 having a temperature about 10 ° C. lower than the temperature in the box 21. Hereinafter, an embodiment of the dehumidification and cooling device according to the present invention having the above-described structure will be described.

When the device is operating, the temperature of the radiator 23 mounted on the outside of the box 21 is raised by the operation of the two electronic cooling elements 28. On the other hand, through the cover 24 ', the space formed by the substrate 23a, the heat guide 23b, the decorative plate 23d, and the side plates 24, that is, the space formed between the pins of the convex portions 23c on both sides. Is delivered.

The heat of the radiator 23 is radiated in the air which enters the space between the ear portions 23c and is released to the outside, so that cooling of the air is achieved.

On the other hand, the temperature of the endothermic heat sink 29 provided in the box 21 is lowered by the operation of the two electronic cooling elements 28. The hot and humid air in the box 21 is sucked into the lid 32 by the intake air blower 36 and guided to the endothermic shock 29. The heat absorbing fan 29 absorbs heat from the air to condense moisture in the air, and the air cooled and dried after passing through the heat absorbing fan 29 returns to the inside of the box 21 through the exhaust port 34. do.

At this time, the motives introduced through the intake air blower 36 are concentrated in the contraction portion 35 of the cover 32 and guided to the endothermic shock 29, so that the endothermic action of the endothermic shock 29 is effectively performed, so that dehumidification and cooling effects are achieved. Is improved.

In this way, the water condensed on the endothermic fan 29 reaches the drain port 40 through the inclined surface 39 of the cover 32 and is discharged to the outside of the box 21 through the drain pipe 41.

As described above, in the dehumidification and cooling apparatus of the present invention, a radiator in contact with an endothermic surface of the electronic cooling element is installed on the outer wall of the box, and an endothermic fan in contact with the endothermic surface of the electronic cooling element is installed in the box, and air is respectively Separate blowers are sent to both the radiator and the endothermic fan. After all, since there is no heat generating element in the box, the inside of the box can be cooled effectively. In addition, the cover that covers the intake blower and the endothermic fan is provided with a contraction part so that the air in the box is concentrated and guided to the endothermic fan, so that the cooling effect can be improved, and the water condensed by dehumidification is discharged to the outside of the box through the drain pipe. Dehumidification can also be achieved satisfactorily.

As a result, dew condensation and temperature rise in the box can be prevented, and the equipment inside the box can maintain high reliability. In addition, in the radiator of the present invention, the side plates for covering the recesses provided on both sides of the thermal guide are located at the front end of the heat guide protruding from both ends of the substrate and the center of the substrate, and the heat guides protruding from both ends of the substrate and the center of the substrate. It is fitted snugly between both ends of the decorative plate located at the tip of. Therefore, the shoulders will not be exposed to the outside and therefore there will not be a possibility that the user will accidentally touch the hot shoulders and normalize them.

In addition, since the decorative plate and the side plates help to form the outer case, a separator additional part to cover the back is unnecessary, and thus the number of parts, the number of assembly stages of the radiator and the overall size of the device can be reduced.

Hereinafter, an improved version of the embodiment will be described with reference to FIGS. 9 to 13.

The improved type in the dehumidification and cooling device embodiment is suitable for smoothing the drainage of water generated by dehumidification from the endotherm regardless of the installation direction of the device. That is, in the improved dehumidification and cooling device, as shown in FIG. 9, a heat absorbing fan 29 in contact with the heat absorbing surface of the front surface of the electronic cooling element 28 is covered with a cover 32 from the front, and the intake opening 33 And the exhaust ports 24 are formed on the upper and lower sides of the lid 32 as in the above-described embodiment. However, unlike the above-described embodiment, the bottom inclined surface is inclined downward from the rear portion of the lid to the front portion and inclined downward from one side of the lid lower side to the other on the inner bottom surface of the lid 32. In the ninth arrow X indicates the downward of the device, which is the front of the device. Moreover, the front inclined surface 101 which inclines from the upper part to the lower front from the inner front surface of the cover 32, and inclines toward the other front from either one of the left and right side parts is formed. Also, the drain port 40 is formed at the lowest and foremost position on the intersection line formed by the bottom slope surface 139 and the front slope surface 102.

That is, instead of the downwardly inclined surface 39 to the right side of the device in the first chamber, the improved type is inclined from the rear to the front and inclined from one of the left and right sides to the other, and from the upper to the lower front (40) and a drain hole (40) which communicates with the outside at the lowest position protruding from the front and bottom of the front slope (101) and the front slope (101) and the bottom slope (139) at one side of the left and right sides and inclined forward to the other. ) Is formed. Except for the installation of the bottom and front slopes 139 and 101, the structure of the improved device is identical to that of the embodiment described above.

As the electronic cooling element 28 is driven according to the above-described improved structure, the temperature of the endothermic 29 is lowered. When the air introduced into the cover 32 through the air inlet 33 passes through the heat absorbing fan 29, the temperature is reduced to lose heat, and at the same time, moisture in the air is condensed and the bottom inclined surface of the cover 32. Dropped above 139, the cooled and dried air is discharged from the exhaust 34.

Dehumidification water (hereinafter referred to as dehumidifying water) flows toward the front portion and the lower side in one of the left and right directions along the slope of the bottom slope surface 139 is discharged through the drain 40.

When this dehumidification and cooling device is used in a state where the endothermic surface of the electronic cooling element 28 is positioned downward, the dehumidified water condensed on the endothermic shock 29 falls on the front inclined surface 101. In this case, the front inclined surface 101 is low with respect to the surface provided with the inlet 33. In addition, since the lower surface of the left and right side is high and one side is low, the dehumidifying water flows downward in accordance with the inclination of the front inclined surface 101 to reach the drain and discharge to the outside.

The structure of the improved apparatus is now described in more detail. Arrows X, Y and Z in FIGS. 10, 11 and 12 indicate the front, the bottom and the right side of the device, respectively.

The inner bottom surface of the lid 32 is formed to have a high left side and a lower right side of the bottom binding surface 139 as shown in FIG. 10, and has a rear portion high and a front portion low as shown in FIG. It is. The inner front surface of the lower portion of the contraction portion 35 formed on the cover 32 is formed such that the upper portion of the front inclined surface 101 is inclined toward the lower rear side as shown in FIG. 11, and as shown in FIG. 12. The left side is inclined backward compared to the right side.

Further, at the intersection of the bottom slope surface 139, the front slope surface 101, and the right inner surface, a drain hole 40 connected to the drain pipe 41 having an outlet to the outside is formed.

If the dehumidification and cooling device having the above-described structure is used in the so-called vertical type attached to the rear wall of the box 21 as shown in FIG. 9, the same effects as in the case of the embodiment described above may be obtained. That is, water condensed on the endothermic shock 29 falls on the bottom inclined surface 139. The water flows to the right front along the slope of the bottom slope 139, and is discharged to the outside of the box 21 through the drain 40 and the drain pipe 41.

A dehumidification and cooling device can also be mounted on the ceiling and used in the horizontal manner shown in FIG.

In this mounting method, the front wall of the cover 32 acts as a bottom surface having a front inclined surface 101 located under the endothermic wall 29. Here, the slope of the inclined surface is such that the drain hole is at the lowest position.

Moisture in the air condenses by the endothermic action of the endothermic shock 29, falls on the front inclined surface 101, flows along the front inclined surface 101, reaches the drain port 40, and is discharged out of the box 21.

As described above, according to the improved type dehumidification and cooling device, the bottom sloped surface and the front inclined surface are formed on the cover to cover the endothermic heat and to receive the dehumidifying water, and the drain hole is formed at the foremost front of the inner surface of the cover. Therefore, in both cases where the device is attached in horizontal and vertical form, the dehumidifying water obtained from the endothermic fan is smoothly discharged to the drain and discharged to the outside. As such, a single cover can be used for both attachment methods without changing the shape of the cover. In addition, the common cover is used to reduce the price, and the mounting direction can be arbitrarily selected.
