Description
Technical Field
The present invention relates to a cooling/heating module and a blower using a thermoelectric element.
Background
Thermoelectric modules using thermoelectric elements (e.g., peltier thermoelectric elements) are used in cooling and heating apparatuses, cooling apparatuses, and refrigerating apparatuses, and recently, are used in various apparatuses that supply or supply heat using electricity, such as domestic and enterprise refrigerators, small-sized vehicle refrigerators, can coolers, and seat cooling and heating apparatuses.
As is well known, a thermoelectric module comprises: the thermoelectric device includes a pair of insulating plates, a plurality of thermoelectric elements (a plurality of P-type thermoelectric semiconductor elements and N-type thermoelectric semiconductor elements) disposed between the insulating plates and electrically connected in series, and a heat transfer medium (for example, a heat transfer plate, a heat transfer pin, a heat sink, etc.) attached to each of the insulating plates.
The cooling and heating module using the thermoelectric module includes a blower (blower) for sending air to the thermoelectric module.
Fig. 1 shows an example of a cooling/heating module using a conventional thermoelectric module.
Fig. 1 shows an example of a cooling/heating module using a conventional thermoelectric module, and as shown in fig. 1, a cooling/heating module 10 includes: a blower 1 and a thermoelectric module 2. The blower 1 sends air to the thermoelectric module 2 side. After the current is supplied, one surface (cooling surface) of the substrate/thermoelectric element 21 of the thermoelectric module 2 is cooled, and the heat transfer medium 22 attached to the cooling surface is also cooled.
The other surface (heat-generating surface) of the substrate/the plurality of thermoelectric elements 21 generates heat, and the heat transfer medium 23 attached to the heat-generating surface also generates heat.
When air is supplied to the cooling side, which is the heat transfer medium 22 attached to the cooling surface, the air is cooled and a cold air flow is supplied to the device including the cooling and heating module 10, and when air is supplied to the heating side, which is the heat transfer medium 23 attached to the heating surface, the air is heated and heated air is supplied to the device.
At this time, if the surface temperature on the cooling side is lower than the saturation temperature of the psychrometric chart, the moisture in the air condenses to the condensation phenomenon on the thermoelectric element cooling surface and the cooling heat transfer medium surface, and condensation (condensed water) occurs. Then, the dew condensation occurring on the surface of the cooling side forms water drops to block the flow path of the cooling side, and at this time, the flow path resistance of the cooling side gradually increases, and the amount of air supplied from the blower 1 to the cooling side gradually decreases to supply more air to the heat generating side. Accordingly, air is not supplied to the cooling side, but only to the heat generating side.
The above-described condensation phenomenon on the cooling side greatly reduces the performance of the cooling/heating module 10.

Hereinafter, the present invention will be described in detail centering on embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the various drawings indicate like elements.
As shown in fig. 2, the cooling and heating module 100 according to the embodiment of the present invention includes: impeller 1, Impeller 111, Impeller 2, and thermoelectric module 130. In this specification an impeller is an object designed to send air in a desired direction. The impeller performs a rotational motion to impart a motive energy source to the fluid, causing the fluid to move in the intended direction.
According to an embodiment, as shown in fig. 2, the cooling and warming module 100 includes: a 1 st blower unit 110 having the 1 st impeller 111 and a 1 st driving device 112 for driving the 1 st impeller 111; the 2 nd blower unit 120 includes the 2 nd impeller 121 and a 2 nd driving device 122 for driving the 2 nd impeller 121.
Fig. 6 shows a blower 1001 including the 1 st blower unit 110 and the 2 nd blower unit 120.
Thus, the cooling and heating module 100 includes: the air blower 1001 and the thermoelectric module device 1002 integrally formed with the air blower 1001 or coupled to the air blower 1001.
The thermoelectric module device 1002 includes the thermoelectric module 130 and includes a thermoelectric module housing that internally encloses the thermoelectric module 130. The thermoelectric module 130 includes: a pair of insulating plates, a thermoelectric section 131 which is a collection of thermoelectric elements disposed between the insulating plates, and heat transfer media 132 and 133 attached to the respective sections of the thermoelectric section 131. For convenience of description, the heat transfer medium 132 attached to the upper side of the thermoelectric part 131 is defined as a cooling side as a heat transfer medium attached to a cooling surface, and the heat transfer medium 133 attached to the lower side of the thermoelectric part 131 is defined as a heat generating side as a heat transfer medium attached to a heat generating surface. However, one of ordinary skill in the art of the present invention should easily deduce that the cooling surface and the heating surface may be switched according to the direction of the current.
The 1 st impeller 111 sucks in outside air and blows it to the cooling side 132 of the thermoelectric module 130. The 2 nd impeller 121 sucks in the outside air and sends the air to the heat generating side 133 of the thermoelectric module 130.
That is, the cooling/heating module 100 according to the technical idea of the present invention is formed with at least two different impellers, and the air sent by each impeller is sent only to the corresponding flow path.
For example, the 1 st impeller 111 corresponds to the 1 st flow path. The 1 st flow path is a path of air blown from the 1 st impeller 111, passing through the cooling side 132, and then discharged through the 1 st discharge port 140. Unlike the conventional technique described with reference to fig. 1, the air sent by the 1 st impeller 111 moves only to the 1 st flow path, and does not flow into the heat generating side 133.
The 2 nd impeller 121 corresponds to the 2 nd flow path. The 2 nd flow path is a path of air which is transmitted from the 2 nd impeller 121, passes through the heat generating side 133, and is discharged through the 2 nd discharge port 150. Similarly, the air sent by the 2 nd impeller 121 flows only into the 2 nd flow path, and does not flow into the cooling side 132.
Thus, according to the technical idea of the present invention, the air flowing in from the outside is discharged to the outside through the 1 st flow path and the 2 nd flow path which are separated from each other and are not communicated.
In this case, even if dew condensation occurs on the surface of the cooling side 132 to increase the flow path resistance, the 1 st impeller 111 can continuously apply wind pressure of a predetermined level or more to the cooling side 132, and thus dew condensation occurring on the surface of the cooling side 132 is pushed out of the cooling side 132 by the wind pressure, for example, to the left side of the cooling side 132 in fig. 2.
The 1 st flow path and the 2 nd flow path are separated from each other by a 1 st separating member 160 formed between the 1 st impeller 111 and the 2 nd impeller 121, the thermoelectric part 131, and a 2 nd separating member 170 separating air passing through the cooling side 132 and air passing through the heating side 133.
The 1 st separating member 160 is connected between one side of the housing of the cooling and heating module 100 and the thermoelectric part 131, and separates the upper side and the lower side of the 1 st separating member 160 without communication.
The plurality of thermoelectric elements formed in the thermoelectric portion 131 are protected by a predetermined sealant. The sealant is coated along the periphery of the plurality of thermoelectric elements between the insulating plates to prevent foreign substances such as moisture from flowing into the thermoelectric element P-type thermoelectric semiconductor element and the thermoelectric semiconductor element N-type element side disposed between the pair of insulating plates, and the above hot spot module coated with the sealant is disclosed in detail in korean patent registration No. 10-1357731, "thermoelectric module having improved sealing structure", of the present applicant, and thus, a detailed description thereof will be omitted.
The 2 nd separating part 170 functions to separate air passing through the cooling side 132 and air passing through the heating side 133 to prevent mixing thereof. The 2 nd separating member 170 is formed between the 1 st exhaust port 140 and an exhaust side where air is exhausted from the thermoelectric module 130, for example, a left side of the thermoelectric module 130 in fig. 2.
At least a part of the 2 nd separating member 170 is formed of a moisture absorbent material that absorbs condensed water, which is dew condensation discharged from the cooling side 132. The moisture-absorbing material may be formed of any material having a predetermined moisture absorption rate or more. For example, the absorbent material may be applied to various embodiments such as nonwoven fabric and absorbent paper.
One surface, for example, the upper surface of the moisture-absorbing material may be formed in the 1 st channel. That is, the one surface is exposed to the 1 st flow path and absorbs the moisture discharged from the cooling side 132.
Further, another surface, for example, the lower surface of the moisture absorbent material may be formed in the 2 nd flow path. That is, the other surface is exposed to the 2 nd flow path. Alternatively, the other surface of the moisture absorbent material, for example, the lower surface thereof is not directly exposed to the 2 nd channel but is in contact with another separating member that separates the 1 st channel and the 2 nd channel. That is, the 2 nd separating member 170 and the moisture absorbent material are formed such that one surface of the moisture absorbent material is directly exposed to the 1 st flow path to directly absorb the condensed water, and the other surface is not directly exposed to the 2 nd flow path and is in contact with the 2 nd separating member 170. At this time, the 2 nd separating member 170 has excellent thermal conductivity, so that the moisture absorbent material is easily dried by the hot air passing through the 2 nd flow path. The 2 nd flow path is a path through which heated air passing through the heat generating side 133 moves, and the moisture absorbent material absorbing moisture may be naturally dried by the heated air.
Thus, it has an effect of solving the problems of contamination, mold or malodor occurring when water is left for a long time. Further, it is possible to solve the problem that moisture is discharged to the outside of the cooling/heating module 100, for example, contamination of a predetermined device having the cooling/heating module 100, an operation failure, or the like.
At least one driving means, for example, a motor, may be formed to drive the 1 st impeller 111 and the 2 nd impeller 121. According to an example, according to an embodiment of the present invention, as shown in fig. 2, a 1 st driving device 112 for driving a 1 st impeller 111 and a 2 nd driving device 122 for driving a 2 nd impeller 121 are formed.
At this time, the driving speeds of the 1 st impeller 111 and the 2 nd impeller 121, for example, the rotating speeds may be individually controlled by the 1 st driving device 112 and the 2 nd driving device 122. It goes without saying that, as shown in fig. 2, the 1 st blower unit 110 is formed in the 1 st flow path, and the 2 nd blower unit 120 is formed in the 2 nd flow path.
The cooling/heating module 100 is configured such that the 1 st blower unit 110, which delivers air to the cooling side 132, supplies a larger amount of flow than the 2 nd blower unit 120. In order to supply a larger flow rate, the 1 st driving device 112 is designed to have a faster driving speed, or the design variables for determining the blowing intensity of the 1 st impeller 111 are different from those of the 2 nd impeller 121.
For example, it is well known that design variables for determining the blowing intensity are various design variables such as the angle, shape, size, or thickness of the wing of the blade, and thus, detailed description thereof is omitted.
Further, according to another embodiment of the present invention, as shown in fig. 3, the 1 st impeller 111 and the 2 nd impeller 121 may be driven by one 3 rd driving device 113. In this case, the 1 st flow path and the 2 nd flow path may be separated without being communicated with each other, and for this purpose, the 1 st impeller 111 and the 2 nd impeller 121 are separated by wrapping a predetermined separating member 1601 around the outer circumferential surface of the trunk of the 3 rd driving unit 113.
The 3 rd driving means 113 may be formed with a 1 st rotation shaft 1131 for transmitting a rotation force to the 1 st impeller 111 and a 2 nd rotation shaft 1132 for transmitting a rotation force to the 2 nd impeller 121. At least one rotating means for individually driving the 1 st and 2 nd rotating shafts 1131 and 1132 is formed inside the trunk of the 3 rd driving means 113, and the rotation speeds of the 1 st and 2 nd rotating shafts 1131 and 1132 can be individually controlled. According to another embodiment, the 1 st and 2 nd rotation shafts 1131 and 1132 may be rotated at the same speed by one rotation device. At this time, as described above, at least one of the design variables for determining the blowing intensity of the 1 st impeller 111 and the 2 nd impeller 121 is formed differently from each other, so that the blowing intensities flowing into the cooling side 132 and the heating side 133, respectively, are made different from each other.
Further, according to the technical idea of the present invention, a heat transfer medium is provided which can make condensation formed on the cooling side 132 more easily discharged in a direction opposite to the outer impeller side of the cooling side 132. This will be explained with reference to fig. 4.
Fig. 4 is a drawing for explaining an example of the heat transfer medium according to the embodiment of the present invention.
As shown in fig. 4, the heat transfer medium formed on the cooling side 132 is formed with a plurality of heat transfer pins or heat transfer plates 132,1321, and the shape of the heat transfer medium is varied as shown in fig. 4 or 5. For example, the heat transfer pins may be formed in a shape connected to each other as shown in fig. 4, or may be formed in a shape separated from each other as shown in fig. 5.
The air flowing into the cooling side 132 through the 1 st impeller 111 moves between the heat transfer pins 132,1321 and is cooled. At this time, when a water droplet having a predetermined size, which is dew condensation, is formed on one surface of the specific heat transfer pin 132,1321, at least one of the heat transfer pins 132,1321 has at least one through hole 133 so that a part of the water droplet moves to the other surface of the specific heat transfer pin.
When the through-hole 133 is formed as described above, the beads are separated to both sides of the specific heat transfer pin, and a plurality of beads smaller than the beads originally formed are formed. The thus divided water droplets can be more easily discharged to the outside of the cooling side 132 by the wind pressure.
Fig. 6 shows a blower that embodies the technical idea of the present invention.
Fig. 6 is a diagram of a blower according to the technical idea of the present invention.
Referring to fig. 6, in a blower 1001 according to the technical idea of the present invention, when a casing 165 is formed, a 1 st impeller 111 and a 2 nd impeller 121, which are different impellers, are formed inside the casing 165.
Also, a separating member 160 separating the inside of the case 165 may be formed. The separating member 160 is formed between the 1 st impeller 111 and the 2 nd impeller 121.
The separating member 160 separates at least a 3 rd flow path, for example, 1621 to the cooling side 132, of air from the 1 st impeller 111 to the thermoelectric module 130, and a 4 th flow path, for example, 1631 to the heat generating side 133, of air from the 2 nd impeller 121 to the thermoelectric module. It goes without saying that the space in which the 1 st impeller 111 is formed and the space in which the 2 nd impeller 121 is formed can be completely separated by the separating member 160 as shown in fig. 2, and can also be separated by the separating member 160 and the driving device as shown in fig. 3. The separation member 160 can separate the 3 rd flow path and the 4 th flow path whenever necessary, and can prevent the air discharged from the 1 st impeller 111 from flowing into the heat generating side 133 or the air discharged from the 2 nd impeller 121 from flowing into the cooling side 132.
Also, the housing 165 includes: a 1 st opening part 162 formed on the 1 st impeller 111 side with reference to the separating member 160 and opened to allow air to flow into the 1 st impeller 111, and a 2 nd opening part 163 formed on the 2 nd impeller 121 side with reference to the separating member 160 and opened to allow air to flow into the 2 nd impeller 121.
Thus, the blower 1001 is integrally formed with or coupled to the thermoelectric module device 1002 to form the cooling and heating module 100.
The cooling and heating module 100 according to an embodiment of the present invention may be applicable to various devices having cooling and/or heating functions. According to an example, the present invention can be applied to a seat, a shield box, and the like, but is not limited thereto.
The present invention has been described with reference to one embodiment illustrated in the accompanying drawings, which are intended to be exemplary only, and it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof. Therefore, the true technical scope of the present invention should be defined according to the claims.
