DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description with reference to the accompanying drawings, the same reference numerals denote the same elements regardless of the reference numerals, and redundant description thereof will be omitted.

Referring to FIGS. 1 and 2, in the air blowing device AR for a vehicle according to the embodiment of the present invention, a plurality of thermoelectric modules including thermoelectric elements are provided, So that cooled air or warm air can be delivered to the inside of the vehicle.

In the heat transfer device according to the embodiment of the present invention, one heat conversion member included in the conversion module (the first module and the second module) is included. However, in another embodiment, a plurality of heat conversion members And can be implemented as a stacked structure. In this way, the surface area of contact with the air or the like can be further maximized. This structure is realized by a structure capable of realizing many contact surfaces in a narrow area on the specific property of the heat conversion member of the present invention formed by a folding structure, A larger number of heat conversion members can be disposed. Of course, in this case, a supporting substrate such as a second intermediate member may be further disposed between the heat converting members stacked. Further, in another embodiment of the present invention, it is also possible to implement a structure including two or more conversion modules.
In the embodiment of the present invention, it is also possible to form the pitches of the heat exchanging members arranged in the portions other than the pitch of the blowing region X heat exchanging members and the blowing regions described in Fig. 3 different from each other. In this case, in particular, in the case of the air blowing area X, the pitch of the flow path pattern of the heat exchange member in the blowing area can be formed to be equal to or larger than the pitch of the flow path pattern of the inner heat exchange member disposed at the location other than the blowing area. In this case, it is preferable that the pitch ratio of the flow path pattern of the heat conversion member disposed in the airflow region X and the heat transfer member disposed outside the airflow region is within a range (0.5 to 2.0): 1 . The cooling efficiency can be maximized in the above range. If the temperature is out of the above range, the air circulation is inhibited or the heat transfer in the heat generating region where the cooling region X is not formed is increased, and the cooling function may be deteriorated.
In addition, the structure of the heat conversion member according to the embodiment of the present invention for forming the flow path pattern can realize a much larger contact area within the same volume than the thermal conversion member having the flat plate structure or the existing heat dissipation fin structure, It is possible to increase the air contact area by 50% or more with respect to the switching member, thereby greatly reducing the size of the module. In addition, various members such as a metal material or a synthetic resin having high heat transfer efficiency such as aluminum can be applied to such a heat conversion member.
FIG. 9 illustrates the implementation of the first through fourth modules in a structure different from the structure of the thermal conversion member described in FIG.
That is, in the structure shown in FIG. 9, the thermal conversion member can be designed by modifying the structure to have the same structure as the
Hereinafter, the structure of the
A thermoelectric module including a thermoelectric device according to an embodiment of the present invention includes a
In the case of a metal substrate, Cu or a Cu alloy can be used, and a thin thickness can be formed in a range of 0.1 mm to 0.5 mm. When the thickness of the metal substrate is 0.1 mm or less, or when the thickness exceeds 0.5 mm, the heat radiation characteristic is excessively high or the thermal conductivity is too high, thereby greatly reducing the reliability of the thermoelectric module. In the case of the
The thickness of the electrode layer may be in the range of 0.01 mm to 0.3 mm. When the thickness of the electrode layer is less than 0.01 mm, the function as an electrode is deteriorated and the electrical conductivity becomes poor. When the thickness of the electrode layer is more than 0.3 mm, the conduction efficiency is lowered due to an increase in resistance.
In this case, a thermoelectric element including a unit element of a layered structure according to an embodiment of the present invention can be applied to the thermoelectric element constituting the unit cell. In this case, The first semiconductor and the second semiconductor may be connected to the
The semiconductor device in the thermoelectric module may be a P-type semiconductor or an N-type semiconductor material. The p-type semiconductor or the n-type semiconductor material is characterized in that the n-type semiconductor element is at least one selected from the group consisting of Se, Ni, Al, Cu, Ag, Pb, (BiTe-based) including gallium (Ga), tellurium (Te), bismuth (Bi), and indium (In), and a bismuth telluride system (BiTe system) containing 0.001 to 1.0 wt% May be formed using a mixture of Bi or Te. For example, the main raw material may be a Bi-Se-Te material, and Bi or Te may be added to the Bi-Se-Te by adding a weight corresponding to 0.001 to 1.0 wt% of the total weight of Bi-Se-Te. That is, when 100 g of Bi-Se-Te is added, it is preferable to add Bi or Te to be added in the range of 0.001 g to 1.0 g. As described above, since the weight range of the substance added to the above-described raw material is not in the range of 0.001 wt% to 0.1 wt%, the thermal conductivity is not lowered and the electric conductivity is lowered, so that the improvement of the ZT value can not be expected. I have.
The P-type semiconductor material may be at least one selected from the group consisting of antimony (Sb), nickel (Ni), aluminum (Al), copper (Cu), silver (Ag), lead (Pb), boron (B), gallium (BiTe-based) including Bi, Te, Bi, and In, and a mixture of Bi or Te corresponding to 0.001 to 1.0 wt% of the total weight of the main raw material It is preferable to form it by using. For example, the main raw material may be a Bi-Sb-Te material, and Bi or Te may be added to the Bi-Sb-Te by adding a weight corresponding to 0.001 to 1.0 wt% of the total weight of the Bi-Sb-Te. That is, when 100 g of Bi-Sb-Te is added, Bi or Te to be added may be added in the range of 0.001 g to 1 g. The weight range of the substance added to the above-described main raw material is not inferior to the range of 0.001 wt% to 0.1 wt%, and the electrical conductivity is lowered, so that improvement of the ZT value can not be expected.
In this case, the electric conductivity of the P-type semiconductor device and the electrical conductivity of the N-type semiconductor device are different from each other, It is possible to improve the cooling performance by forming one of the volumes to be different from the volume of the other semiconductor elements facing each other.
That is, the different sizes of the semiconductor elements of the unit cells arranged opposite to each other can be achieved by forming the entire shape differently, or by forming the diameter of either one of the semiconductor elements having the same height wider, It is possible to realize a method of making the height or cross-section diameter of the semiconductor device different. In particular, the diameter of the N-type semiconductor device is formed larger than that of the P-type semiconductor device so that the volume can be increased to improve the thermoelectric efficiency.
Fig. 12 shows a modified embodiment in which the shape of the thermoelectric element described in Fig. 10 is changed.

In the case of applying the same material and the same amount of material as the thermoelectric element having a single cross-sectional area such as a cubic structure, it is possible to widen the area of the first element portion and the second element portion, The advantage of being able to increase the temperature difference DELTA T between the first element portion and the second element portion can be realized. When the temperature difference is increased, the amount of free electrons moving between the hot side and the cold side increases, so that the electricity generation amount increases, and in the case of heat generation or cooling, the efficiency increases.
Accordingly, the
In another aspect of this embodiment of the structure, in the
Further, in the present embodiment, the first cross-sectional area in the horizontal direction of the
FIG. 13 shows an example in which the structure of the thermoelectric device according to the embodiment of the present invention described above with reference to FIGS. 10 and 12 is implemented by different methods and configurations.
Referring to FIG. 13, in another embodiment of the present invention, the structure of the semiconductor device described above may be realized as a structure of a laminate structure rather than a bulk structure, thereby further improving the thinning and cooling efficiency. Specifically, the structures of the
Referring to FIG. 13, FIG. 13 is a conceptual diagram of a process for manufacturing the unit member of the above-described laminated structure. 13, a paste containing a semiconductor material is formed into a paste, a paste is applied on a substrate 111 such as a sheet or a film to form a semiconductor layer 112 to form a single unit member 110 . As shown in FIG. 13, the unit member 110 forms a laminated structure by stacking a plurality of unit members 100a, 100b, and 100c, and then cuts the laminated structure to form a unit
The process of applying the semiconductor paste on the substrate 111 in the above-described process can be realized by various methods. For example, tape casting, that is, a very fine semiconductor material powder can be applied to a water- a slurry is prepared by mixing any one selected from a solvent, a binder, a plasticizer, a dispersant, a defoamer and a surfactant to prepare a slurry, And then molding it according to the desired thickness with a predetermined thickness. In this case, materials such as films and sheets having a thickness in the range of 10 to 100 μm can be used as the base material, and the P-type material and the N-type material for recycling the above-mentioned bulk type device can be applied as they are Of course.
In the step of laminating the unit members 110 in a multilayer structure, the laminate structure may be formed by pressing at a temperature of 50 ° C to 250 ° C. In the embodiment of the present invention, To 50 < / RTI > Thereafter, a cutting process can be performed in a desired shape and size, and a sintering process can be added.
The unit thermoelectric elements in which a plurality of unit members 110 manufactured in accordance with the above-described processes are stacked can secure the uniformity of thickness and shape size. That is, the conventional bulk-shaped thermoelectric element cuts the sintered bulk structure after the ingot grinding and fine-finishing ball-mill processes, so that a large amount of material is lost in the cutting process, However, in the unit thermoelectric element of the laminated structure according to the embodiment of the present invention, after the multilayer structure of sheet-like unit members is laminated, the sheet laminate It is possible to achieve uniformity of the bar material having a uniform thickness of the material and thickness of the whole unit thermoelectric device to be as thin as 1.5 mm or less, . The finally implemented structure can be cut into the shape of FIG. 10 (d) like the structure of FIG. 9 or the structure of the thermoelectric device according to the embodiment of the present invention described above with reference to FIG. Such a structure can be applied to a structure in which the first thermoelectric module or the second thermoelectric module of the thermal conversion device described above with reference to FIG. 1 is independent or mutually combined.
Particularly, in the step of manufacturing a unit thermoelectric element according to the embodiment of the present invention, a step of forming a conductive layer on the surface of each unit member 110 in the step of forming a laminated structure of the unit member 110 is further implemented .
That is, a conductive layer similar to the structure of Fig. 14 can be formed between the unit members of the laminated structure of Fig. 13 (c). The conductive layer may be formed on the opposite side of the substrate surface on which the semiconductor layer is formed. In this case, the conductive layer may be formed as a patterned layer such that a region where the surface of the unit member is exposed is formed. As a result, the electrical conductivity can be increased, the bonding force between the unit members can be improved, and the advantage of lowering the thermal conductivity can be realized.
14 shows various modifications of the conductive layer C according to the embodiment of the present invention. The patterns in which the surface of the unit member is exposed include the patterns shown in Figs. 12 (a) and 12 (b) the, as shown in, the closed opening pattern (c 1, c 2), as shown in (c), (d) of the mesh-type structure, or 14, including, open the aperture pattern (c 3, c 4) And a line type including a line type. The conductive layer is advantageous in that not only the adhesion between the unit members in the unit thermoelectric elements formed by the laminated structure of the unit members but also the thermal conductivity between the unit members is lowered and the electrical conductivity is improved, The cooling capacity (Qc) and? T (占 폚) of the bulk-type thermoelectric element are improved, and particularly the power factor is 1.5 times, that is, the electric conductivity is increased 1.5 times. The increase of the electric conductivity is directly related to the improvement of the thermoelectric efficiency, so that the cooling efficiency is improved. The conductive layer may be formed of a metal material, and metal materials of Cu, Ag, Ni, or the like may be used.
In the case where the unit thermoelectric element of the laminated structure described above is applied to the thermoelectric module shown in FIG. 3 and FIG. 4, that is, between the
15, the
That is, the thermoelectric module can be formed by arranging the first substrate and the second substrate such that the surfaces of the semiconductor layer and the substrate are adjacent to each other. However, as shown in FIG. 15 (b) , And the side portions of the unit thermoelectric elements are arranged adjacent to the first and second substrates. In such a structure, the end portion of the conductive layer is exposed to the side surface rather than the horizontal arrangement structure, thereby lowering the heat conduction efficiency in the vertical direction and improving the electric conduction characteristic, thereby further improving the cooling efficiency. Further, the shape of FIG. 12 may be cut and applied as shown in FIG. 15 (c).
As described above, in the thermoelectric device applied to the thermoelectric module of the present invention, which can be implemented in various embodiments, the shapes and sizes of the first semiconductor element and the second semiconductor element facing each other are the same, Considering the fact that the electrical conductivity of the semiconductor element and the electrical conductivity of the N-type semiconductor element are different from each other and serve as an element that hinders the cooling efficiency, the volume of one of them is formed differently from the volume of other semiconductor elements opposed to each other So that the cooling performance can be improved.
In other words, the formation of the semiconductor elements arranged in mutually opposing directions in different volumes can be achieved by forming the entire shape differently, or by forming the diameter of one of the semiconductor elements having the same height wider, It is possible to implement the method of making the height or the cross-section diameter different. In particular, the diameter of the N-type semiconductor device may be larger than that of the P-type semiconductor device so that the volume of the N-type semiconductor device may be increased to improve the thermoelectric efficiency.
As described above, the thermoelectric elements having various structures according to one embodiment of the present invention and the thermoelectric module including the thermoelectric modules can be freely adjusted in cold wind and hot air by applying the thermoelectric module to a blower for a vehicle as described above, Thereby maximizing convenience. In particular, when the system is linked to an air conditioning system of an electric car, it is possible to eliminate the problem of reduction in travel distance due to reduction in battery consumption of the electric vehicle, and the operation of adjusting the direction and temperature of the current can be very easily implemented. .
In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention. The technical spirit of the present invention should not be limited to the above-described embodiments of the present invention, but should be determined by the claims and equivalents thereof.
