Description

[0001] Cross-references to related applications

[0002] This application claims priority to Korean Patent Application No. 10-2021-0064366, filed on May 18, 2021, the entire contents of which are incorporated herein by reference for all purposes. Technical Field

[0003] This invention relates to a thermoelectric module, and more specifically, to a thermoelectric module that can improve comfort while reducing discomfort. Background Technology

[0004] Because the temperature control system of an air conditioning unit controls the temperature based on the air temperature, this system requires a significant amount of energy, and users spend a considerable amount of time sensing temperature changes. Therefore, there are limitations in improving temperature control efficiency and energy efficiency to a certain level or higher.

[0005] Recently, a temperature control system has been developed that allows thermoelectric modules capable of heating and cooling to come into direct contact with the user.

[0006] Typically, thermoelectric modules are manufactured by connecting electrodes to P-type and N-type thermoelectric materials disposed on a substrate, and have the advantages of low heat loss and fast temperature control.

[0007] Meanwhile, when the thermoelectric module is used to cool an object (e.g., a human body), condensation occurs on the contact portion of the thermoelectric module that contacts the object (the low-temperature portion of the thermoelectric module) due to the temperature difference with the surroundings (e.g., the ambient air).

[0008] However, condensate generated on the low-temperature section of the thermoelectric module often cannot be smoothly discharged to the outside of the contact area, but instead remains between the thermoelectric module and the contact target (e.g., the contact area with the human body). Therefore, the amount of condensate retained increases with the duration of use, leading to increased discomfort and reduced comfort.

[0009] Furthermore, when condensate remains on the contact parts of the thermoelectric module, the performance of the thermoelectric module deteriorates, and unnecessary power consumption increases.

[0010] Therefore, various studies have recently been conducted to minimize condensate retention in the low-temperature section of thermoelectric modules and improve comfort, but the results remain insufficient. Therefore, a technology needs to be developed to minimize condensate retention and improve comfort.

[0011] The information disclosed in this Background section is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission of prior art known to those skilled in the art or any form of implication. Summary of the Invention

[0012] Aspects of the present invention aim to provide a thermoelectric module configured to improve comfort while reducing discomfort.

[0013] In various aspects, the present invention also aims to minimize the retention of condensate on the contact surface of the thermoelectric module that comes into contact with the object, thereby improving comfort.

[0014] In various aspects, the present invention also aims to minimize the performance degradation of thermoelectric modules and improve energy efficiency.

[0015] In all respects, the present invention also aims to minimize the leakage of condensate to the outside and achieve a fresh and comfortable user environment.

[0016] The objectives to be achieved by the exemplary embodiments are not limited to those described above, but also include objectives or effects that can be understood from the schemes or embodiments described below.

[0017] Aspects of the present invention provide a thermoelectric module comprising: a unit thermoelectric member having a contact portion configured to make contact with an object; and a hydrophobic pattern disposed on the contact portion and configured to guide condensate generated on the contact portion to the outside of the contact portion.

[0018] This is to minimize the retention of condensate generated in the thermoelectric module and improve comfort.

[0019] That is, when a thermoelectric module is used to cool an object (e.g., a human body), condensation occurs on the contact portion of the thermoelectric module (the low-temperature portion of the thermoelectric module) where it contacts the object due to the temperature difference with the surroundings (e.g., the ambient air). However, the condensation generated on the low-temperature portion of the thermoelectric module usually cannot be smoothly discharged to the outside of the contact portion, but instead remains between the thermoelectric module and the contact portion (e.g., the contact area of ​​the human body). Therefore, the amount of condensation retained increases with the duration of use, leading to increased discomfort and reduced comfort. Furthermore, when condensation remains on the contact portion of the thermoelectric module, the performance of the thermoelectric module deteriorates, and unnecessary power consumption increases.

[0020] Conversely, according to an exemplary embodiment of the invention, a hydrophobic pattern can be provided on the contact portion configured to come into contact with an object, thereby guiding condensate generated on the contact portion to the outside of the contact portion. Therefore, the advantageous effect of minimizing condensate retention on the contact portion of the thermoelectric module and improving comfort can be achieved.

[0021] According to an exemplary embodiment of the present invention, a hydrophobic pattern can be provided on the contact portion (the portion that comes into contact with the object) of the thermoelectric module, which makes it possible to suppress the adhesion or retention of condensate on the portion where the hydrophobic pattern is provided. Therefore, condensate generated on the contact portion can be pushed towards the portion without the hydrophobic pattern, thereby guiding the condensate to the outside of the contact portion.

[0022] According to an exemplary embodiment of the present invention, the unit thermoelectric component may include at least one of N-type thermoelectric material and P-type thermoelectric material.

[0023] For example, a unit thermoelectric component may include: an N-type thermoelectric material; a P-type thermoelectric material spaced apart from the N-type thermoelectric material; a first electrode electrically connected to a first end of the N-type thermoelectric material and a first end of the P-type thermoelectric material; and a second electrode connected to a second end of the N-type thermoelectric material and a second end of the P-type thermoelectric material, respectively.

[0024] According to an exemplary embodiment of the present invention, the hydrophobic pattern can guide condensate generated on the outer surface of the first electrode to the outer region of the second electrode.

[0025] This is to ensure that condensate guided to the outside of the contact area by the hydrophobic pattern falls into the outer region of the second electrode, rather than onto the upper surface of the second electrode.

[0026] That is, the hydrophobic pattern can be configured such that condensate guided to the outside of the contact portion by the hydrophobic pattern falls onto the upper surface of the second electrode. However, condensate remaining on the upper surface of the second electrode may reduce energy efficiency and the performance of the thermoelectric module and lead to unstable power supply.

[0027] Conversely, according to an exemplary embodiment of the present invention, since the condensate guided to the outside of the contact portion by the hydrophobic pattern falls into the outer region of the second electrode, the amount of condensate remaining on the upper surface of the second electrode can be minimized. Therefore, the advantageous effects of stable power supply and minimizing performance degradation of the thermoelectric module caused by condensate can be obtained.

[0028] Depending on the required conditions and design specifications, hydrophobic patterns can have various structures.

[0029] For example, the hydrophobic pattern may include: a first pattern provided along a first direction and disposed on the outer surface of the first electrode; and a second pattern disposed on the outer surface of the first electrode and connected to the first pattern to point to a second direction intersecting the first direction.

[0030] The second electrode can be disposed along the longitudinal direction of the first electrode, and a portion of the second electrode can be disposed to overlap with the first electrode. The first pattern can be disposed to cover the first electrode along the longitudinal direction (based on...).Figure 3 The outermost edge part (in the left and right directions).

[0031] As described above, the first pattern can cover the outermost edge portion of the first electrode along the longitudinal direction, which allows condensate generated on the contact portion to be prevented from falling onto the upper surface of the second electrode through the outermost edge portion of the first electrode along the longitudinal direction. Therefore, the advantageous effects of stable power supply and minimizing performance degradation of the thermoelectric module caused by condensate can be achieved.

[0032] According to an exemplary embodiment of the present invention, the thermoelectric module may include an absorption member connected to the unit thermoelectric member and configured to absorb condensate.

[0033] As described above, an absorbent component can be provided, which prevents condensate pushed out from the contact area from falling into unwanted locations. Therefore, the beneficial effects of creating a more comfortable user environment and reducing unpleasant sensations can be achieved.

[0034] According to an exemplary embodiment of the present invention, the thermoelectric module may include a heat sink connected to the unit thermoelectric component.

[0035] As described above, a heat sink can be connected to the unit thermoelectric component, and heat exceeding the heat capacity of the unit thermoelectric component can be discharged (transferred) to the heat sink (e.g., heat generated from the unit thermoelectric component can be discharged to a heat sink with a relatively high heat capacity). Therefore, the beneficial effects of further improving the heat transfer efficiency and cooling performance of the thermoelectric module can be obtained.

[0036] The heat sink can be made of a porous material with pores, and each pore can be filled with an absorbent component.

[0037] Since the pores of the heat sink are filled with absorbing components as described above, the beneficial effects of simplifying the structure of the thermoelectric module and improving the space utilization and design freedom of the thermoelectric module can be achieved.

[0038] According to an exemplary embodiment of the present invention, the thermoelectric module may include a fan configured to generate a forced airflow toward a heat sink.

[0039] As mentioned above, a fan can be used to generate forced airflow toward the heatsink, which allows the heatsink to be cooled. Therefore, it is possible to further improve the heat dissipation performance (heat capacity) of the heatsink.

[0040] Furthermore, the fan not only cools the radiator but also dries the absorbent components to remove absorbed condensate. Therefore, it is advantageous to maintain the absorbent components' water absorption capacity consistently and to minimize leakage (e.g., dripping) of condensate to the outside.

[0041] According to an exemplary embodiment of the present invention, the thermoelectric module may include: a first through hole, disposed through a first electrode and configured to discharge condensate from a contact portion through the first through hole; a second through hole, disposed in at least one of an N-type thermoelectric material and a P-type thermoelectric material and configured to be in fluid communication with the first through hole; and a third through hole, disposed in a second electrode and configured to be in fluid communication with the second through hole.

[0042] As described above, the thermoelectric module may include a first through-hole, a second through-hole, and a third through-hole that are continuously fluidly connected to each other, allowing condensate generated on the contact portion to be discharged to the absorption member (or the lower part of the second electrode) through the first through-hole, the second through-hole, and the third through-hole. Therefore, it is advantageous to minimize the amount of condensate retained (residual) on the contact portion and reduce the time required to drain the condensate.

[0043] According to an exemplary embodiment of the present invention, the thermoelectric module may include a guiding member disposed between the unit thermoelectric member and the absorption member and configured to guide condensate from the unit thermoelectric member to the absorption member via the guiding member.

[0044] For example, the cross-sectional area of ​​the guiding member can gradually increase from the first end adjacent to the unit thermoelectric member toward the second end adjacent to the absorbing member.

[0045] As described above, the cross-sectional area of ​​the guiding member can gradually increase from one end to the other, which allows the condensate guided by the guiding member to be dispersed over a larger area. Therefore, it is possible to achieve the beneficial effect of further improving the condensate absorption efficiency and performance of the absorption member.

[0046] A hydrophobic coating can be applied to the surface of the guide member. As described above, the hydrophobic coating can be applied to the surface of the guide member, which allows condensate flowing downwards along the surface of the guide member to be absorbed more quickly by the absorbent member.

[0065] Reference Figures 1 to 6 According to an exemplary embodiment of the present invention, the thermoelectric module 10 includes: unit thermoelectric components 100, each unit thermoelectric component 100 including a contact portion 102 that can contact an object; and hydrophobic patterns 200 respectively disposed on the contact portions 102, and each hydrophobic pattern 200 is configured to guide condensate generated on the contact portion 102 to the outside of the contact portion 102.

[0066] For reference, the thermoelectric module 10 according to an exemplary embodiment of the present invention can be installed on various objects, and the present invention is not limited or restricted by the type and structure of the object.

[0067] In the following, an example of a thermoelectric module 10 according to an exemplary embodiment of the present invention being mounted on a part of the human body to cool that part of the human body will be described.

[0068] The unit thermoelectric component 100 includes a contact portion 102 that can come into contact with an object (e.g., a human body).

[0069] For example, the contact portion 102 may have a flat or curved surface that can make contact with an object. The present invention is not limited or restricted by the structure and shape of the contact portion 102.

[0070] In the following description, an example will be given in which the contact portion 102 of the unit thermoelectric component 100 has a flat surface corresponding to each of the second electrodes 140.

[0071] The thermoelectric module 10 may include only a single unit thermoelectric component 100 or may include multiple unit thermoelectric components 100.

[0072] In the following description, an example of a thermoelectric module 10 comprising a plurality of unit thermoelectric components 100 will be described. In this case, the plurality of unit thermoelectric components 100 may be connected in series or in parallel to the power supply unit.

[0073] For reference, the unit thermoelectric element 100 is an element that converts heat energy and electrical energy and is also called a Peltier element, thermoelectric cooler (TEC), etc. The unit thermoelectric element 100 is widely used as a cooling or heating device that utilizes the Peltier effect. In the Peltier effect, when an electric current flows through the unit thermoelectric element 100, one part of the unit thermoelectric element 100 (the high-temperature part) is heated, and another part of the unit thermoelectric element 100 (the low-temperature part) is cooled.

[0074] According to an exemplary embodiment of the present invention, the unit thermoelectric component 100 may include at least one of N-type thermoelectric material 110 and P-type thermoelectric material 120. Hereinafter, examples will be described of the unit thermoelectric component 100 including both N-type thermoelectric material 110 and P-type thermoelectric material 120.

[0075] For example, the unit thermoelectric component 100 may include: an N-type thermoelectric material 110; a P-type thermoelectric material 120 spaced apart from the N-type thermoelectric material 110; a first electrode 130 configured to electrically connect one end of the N-type thermoelectric material 110 and one end of the P-type thermoelectric material 120; and a second electrode 140 connected to the other end of the N-type thermoelectric material 110 and the other end of the P-type thermoelectric material 120, respectively.

[0076] Various changes can be made to the quantity and arrangement of the N-type thermoelectric material 110 and the P-type thermoelectric material 120 according to required conditions and design specifications. For example, the N-type thermoelectric material 110 and the P-type thermoelectric material 120 can be arranged in a straight line pattern (arranged in a straight line shape). According to various exemplary embodiments of the present invention, the N-type thermoelectric material and the P-type thermoelectric material can be arranged in a curved pattern or other patterns. The present invention is not limited or restricted by the shape and structure of the N-type thermoelectric material and the P-type thermoelectric material arrangement.

[0077] For example, the N-type thermoelectric material 110 and the P-type thermoelectric material 120 can be configured to have a protruding rod shape. Both the N-type thermoelectric material 110 and the P-type thermoelectric material 120 can be made from powders used in typical thermoelectric semiconductor elements (e.g., at least one selected from the group consisting of Bi-Te based alloy powders, Pb-Te based alloy powders, Si-Ge based alloy powders, Fe-Si based alloy powders, and Co-Sb based alloy powders). The present invention is not limited or restricted by the materials and properties of the N-type thermoelectric material 110 and the P-type thermoelectric material 120.

[0078] A first electrode 130 is provided to electrically connect one end (e.g., the upper end) of the N-type thermoelectric material 110 and one end (e.g., the upper end) of the P-type thermoelectric material 120.

[0079] The first electrode 130 is configured to be simultaneously connected to both the N-type thermoelectric material 110 and the P-type thermoelectric material 120. This invention is not limited or constrained by the structure of the first electrode 130.

[0080] The first electrode 130 can be made of a typical metallic material that can be electrically connected to the N-type thermoelectric material 110 and the P-type thermoelectric material 120. The present invention is not limited or restricted by the material of the first electrode 130. For example, the first electrode 130 can be made of at least one material selected from the group consisting of copper (Cu), nickel (Ni), carbon (C), titanium (Ti), tungsten (W), silver (Ag), platinum (Pt), palladium (Pd), and aluminum (Al).

[0081] The second electrode 140 is electrically connected to the other end (e.g., the lower end) of the N-type thermoelectric material 110 and the other end (e.g., the lower end) of the P-type thermoelectric material 120. Power is applied to the second electrode 140 from the power supply unit.

[0082] In this example, applying electricity to the second electrode 140 is defined as including applying a forward current or a reverse current to the second electrode 140. For example, when a forward current is applied to the second electrode 140, the unit thermoelectric member 100 can be heated (e.g., the first electrode can be defined as a high-temperature part, and the second electrode can be defined as a low-temperature part). On the other hand, when a reverse current is applied to the second electrode 140, the unit thermoelectric member 100 can be cooled (e.g., the second electrode can be defined as a high-temperature part, and the first electrode can be defined as a low-temperature part).

[0083] The second electrode 140 can be made of a typical metallic material that can be electrically connected to the N-type thermoelectric material 110 and the P-type thermoelectric material 120. The present invention is not limited or restricted by the material of the second electrode 140. As an example, the second electrode 140 can be made of at least one material selected from the group consisting of copper (Cu), nickel (Ni), carbon (C), titanium (Ti), tungsten (W), silver (Ag), platinum (Pt), palladium (Pd), and aluminum (Al).

[0084] Meanwhile, in the exemplary embodiments of the invention shown and described above, an example is described where the second electrode 140 is respectively connected to one end of the N-type thermoelectric material 110 and the other end of the P-type thermoelectric material 120. However, when the thermoelectric module 10 includes a plurality of unit thermoelectric components 100 connected in series, the second electrode 140 may also be configured to electrically connect two adjacent unit thermoelectric components 100. Two adjacent unit thermoelectric components 100 may share a single second electrode 140. For example, based on Figure 1 Two adjacent thermoelectric components 100 can be electrically connected to each other through the second electrode 140.

[0085] Furthermore, in the exemplary embodiments of the invention shown and described above, an example is described where the unit thermoelectric member 100 is configured as a block having a predetermined thickness. However, according to various exemplary embodiments of the invention, the unit thermoelectric member may be configured as a flexible thin film.

[0086] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A hydrophobic pattern 200 is provided to guide the condensate generated on the contact portion 102 of the thermoelectric module 10 to the outside of the contact portion 102.

[0087] According to an exemplary embodiment of the present invention, the hydrophobic pattern 200 may be disposed on the outer surface of the defined contact portion 102 of the first electrode 130 (based on...). Figure 3 (on the upper surface).

[0088] As described above, a hydrophobic pattern 200 is provided on the contact portion 102 (the portion that comes into contact with the object) of the thermoelectric module 10, which makes it possible to suppress the adhesion or retention of condensate on the portion provided with the hydrophobic pattern 200. Therefore, the condensate generated on the contact portion 102 can be pushed toward the portion without the hydrophobic pattern 200, thereby guiding the condensate to the outside of the contact portion 102.

[0089] The hydrophobic pattern 200 can be made of various materials with hydrophobic properties, and the present invention is not limited or restricted by the material and properties of the hydrophobic pattern 200. For example, the hydrophobic pattern 200 can be made of materials such as Teflon (PTFE), polymer materials such as P or PMMA, polydimethylsiloxane (PDMS), or Pranic (F127).

[0090] The hydrophobic pattern 200 can be formed by coating or spraying a hydrophobic material onto the contact portion 102 of the thermoelectric module 10. The present invention is not limited or restricted by the method of forming the hydrophobic pattern 200.

[0091] According to an exemplary embodiment of the present invention, a hydrophobic pattern 200 is provided to guide condensate generated on the outer surface of the first electrode 130 to the outer region of the second electrode 140.

[0092] This is to ensure that condensate guided by the hydrophobic pattern 200 to the outside of the contact portion 102 falls into the outer region of the second electrode 140, rather than falling onto the upper surface of the second electrode 140 (based on...). Figure 3 )superior.

[0093] That is, the hydrophobic pattern 200 can be configured such that condensate guided by the hydrophobic pattern 200 to the outside of the contact portion 102 falls onto the upper surface of the second electrode 140. However, the condensate remaining on the upper surface of the second electrode 140 may reduce the energy efficiency and performance of the thermoelectric module 10 and make it difficult to supply power stably.

[0094] Conversely, according to an exemplary embodiment of the present invention, since the condensate guided to the outside of the contact portion 102 by the hydrophobic pattern 200 falls into the outer region of the second electrode 140, the amount of condensate remaining on the upper surface of the second electrode 140 can be minimized. Therefore, the advantageous effects of stable power supply and minimizing performance degradation of the thermoelectric module 10 caused by condensate can be obtained.

[0095] Depending on the required conditions and design specifications, the hydrophobic pattern 200 can have various structures. This invention is not constrained or limited by the shape and structure of the hydrophobic pattern 200.

[0096] For example, the hydrophobic pattern 200 may include a first pattern 210 provided along a first direction and disposed on the outer surface of the first electrode 130, and a second pattern 220 disposed on the outer surface of the first electrode 130 and connected to the first pattern 210 to point to a second direction intersecting the first direction.

[0097] For example, the first pattern 210 and the second pattern 220 can together define an approximate "T" shape.

[0098] According to various exemplary embodiments of the present invention, the hydrophobic pattern may have a "C" shape, an "S" shape, an "X" shape, a "U" shape, etc.

[0099] Furthermore, in the exemplary embodiments of the invention shown and described above, an example is described where the hydrophobic pattern 200 is partially disposed on the outer surface of the defined contact portion 102 of the first electrode 130. However, according to various exemplary embodiments of the invention, the hydrophobic pattern may be disposed on the entire outer surface of the first electrode.

[0100] The second electrode 140 may be disposed along the longitudinal direction of the first electrode 130, and a portion of the second electrode 140 may be disposed to overlap with the first electrode 130. The first pattern 210 may be disposed to cover the first electrode 130 along the longitudinal direction (based on...). Figure 3 The outermost edge part (in the left and right directions).

[0101] As described above, the first pattern 210 can cover the outermost edge portion of the first electrode 130 in the longitudinal direction, which makes it possible to suppress condensate generated on the contact portion 102 from falling onto the upper surface of the second electrode 140 through the outermost edge portion of the first electrode 130 in the longitudinal direction. Therefore, the advantageous effects of stable power supply and minimizing the performance degradation of the thermoelectric module 10 caused by condensate can be obtained.

[0102] According to an exemplary embodiment of the present invention, the thermoelectric module 10 may include an absorption member 300, which is connected to the unit thermoelectric member 100 and configured to absorb condensate.

[0103] As described above, the absorption member 300 is provided, which makes it possible to prevent condensate water pushed out from the contact portion 102 from falling into unwanted locations. Therefore, the beneficial effects of achieving a more comfortable user environment and reducing unpleasantness can be obtained.

[0104] The absorbent member 300 can be made of various materials capable of absorbing condensate. This invention is not limited or restricted by the type and properties of the absorbent member 300. For example, the absorbent member 300 can be made of superabsorbent polymer (SAP), phase change material (PCM), etc.

[0105] For example, the absorption member 300 can be connected to the lower part of the second electrode 140, and the condensate discharged from the contact portion 102 can be absorbed by the absorption member 300 after flowing along the N-type thermoelectric material 110 (or P-type thermoelectric material) and the second electrode 140.

[0106] According to various exemplary embodiments of the present invention, the absorbing member may be connected to the side surface of the second electrode (or the first electrode). Optionally, the absorbing member may be connected to the side surface of an N-type thermoelectric material (or a P-type thermoelectric material).

[0107] According to an exemplary embodiment of the present invention, the thermoelectric module 10 may include a heat sink 400 connected to the unit thermoelectric component 100.

[0108] The radiator 400 can be configured to dissipate the heat generated from the unit thermoelectric component 100 to the outside of the unit thermoelectric component 100.

[0109] For example, the heat sink 400 can be connected to the lower part of the second electrode 140 (based on...). Figure 4 ).

[0110] As described above, the radiator 400 can be connected to the unit thermoelectric component 100, and heat exceeding the heat capacity of the unit thermoelectric component 100 can be discharged (transferred) to the radiator 400 (e.g., heat generated from the unit thermoelectric component can be discharged to the radiator with a relatively high heat capacity). Therefore, the advantageous effect of further improving the heat transfer efficiency and cooling performance of the thermoelectric module 10 can be obtained.

[0111] The heat sink 400 can be made of a porous material with pores 410. The pores 410 can be filled with an absorbent member 300.

[0112] The pore 410 can be configured as a hole, groove, slit, etc., and the present invention is not constrained or limited by the shape and structure of the pore 410.

[0113] Since the pores 410 of the heat sink 400 are filled with the absorption member 300 as described above, the beneficial effects of simplifying the structure of the thermoelectric module and improving the space utilization and design freedom of the thermoelectric module can be achieved.

[0114] For reference, in the exemplary embodiments of the invention shown and described above, an example is described where the pores 410 of the heat sink 400 are filled with the absorber member 300. However, according to various exemplary embodiments of the invention, the heat sink and the absorber member can be separated.

[0115] According to an exemplary embodiment of the present invention, the thermoelectric module 10 may include a fan 500 configured to generate a forced airflow toward the heat sink 400.

[0116] Typical axial fans or centrifugal fans can be used as fan 500, and the present invention is not limited or restricted by the type and structure of fan 500.

[0117] As described above, fan 500 can be used to generate forced airflow toward heat sink 400, which allows heat sink 400 to be cooled. Therefore, the beneficial effect of further improving the heat dissipation performance (heat capacity) of heat sink 400 can be obtained.

[0118] Furthermore, the fan 500 not only cools the radiator 400, but also dries the absorbent member 300 to remove absorbed condensate. Therefore, it is advantageous to maintain the absorbent performance of the absorbent member 300 stably and minimize leakage (e.g., dripping) of condensate to the outside.

[0119] Reference Figure 5 According to various exemplary embodiments of the present invention, the thermoelectric module 10 may include: a first through-hole 132, which is provided through the first electrode 130 and configured to discharge condensate from the contact portion 102; second through-holes 112 and 122, which are provided in at least one of the N-type thermoelectric material 110 and the P-type thermoelectric material 120 and configured to be in fluid communication with the first through-hole 132; and a third through-hole 142, which is provided in the second electrode 140 and configured to be in fluid communication with the second through-holes 112 and 122.

[0120] In the following text, examples will be described where the second through holes 112 and 122 are respectively provided in the N-type thermoelectric material 110 and the P-type thermoelectric material 120.

[0121] For example, the first through hole 132, the second through holes 112 and 122, and the third through hole 142 can each have a straight shape and be along the vertical direction (based on...). Figure 5 The vias are continuously fluidly connected to each other. According to various exemplary embodiments of the present invention, the first through hole, the second through hole, and the third through hole may each have a curved shape or other shapes.

[0122] As described above, the thermoelectric module 10 may include a first through-hole 132, second through-holes 112 and 122, and a third through-hole 142 that are continuously in fluid communication with each other. This allows condensate generated on the contact portion 102 to be discharged (W) to the absorption member 300 (or the lower part of the second electrode) through the first through-hole 132, second through-holes 112 and 122, and third through-hole 142. Therefore, it is advantageous to minimize the amount of condensate retained (residual) on the contact portion 102 and reduce the time required to drain the condensate.

[0123] Reference Figure 6 According to various exemplary embodiments of the present invention, the thermoelectric module 10 may include a guiding member 310 disposed between the unit thermoelectric member 100 and the absorption member 300 and configured to guide condensate from the unit thermoelectric member 100 to the absorption member 300.

[0124] The guide member 310 is provided so that the condensate W flowing downward along the unit thermoelectric member 100 is quickly and effectively absorbed by the absorption member 300.

[0125] The guide member 310 may have various structures configured to guide condensate to the absorber member 300, and the present invention is not limited or restricted by the structure of the guide member 310.

[0126] For example, the guide member 310 can be configured such that its cross-sectional area (e.g., trapezoidal cross-sectional shape) extends from one end adjacent to the unit thermoelectric member 100 (based on...). Figure 6 (The upper end) faces the other end adjacent to the absorbing member 300 (based on) Figure 6 (The lower end) gradually increases in size. Therefore, condensate flowing downward along the unit thermoelectric component 100 can be guided to the absorption component 300 along the inclined surface of the guide component 310.

[0127] As described above, the cross-sectional area of ​​the guiding member 310 can gradually increase from one end to the other, which allows the condensate guided by the guiding member 310 to be dispersed over a larger area. Therefore, it is possible to obtain the beneficial effect of further improving the condensate absorption efficiency and performance of the absorption member 300.

[0128] A hydrophobic coating 312 may be applied to the surface of the guide member 310.

[0129] The hydrophobic coating 312 may be made of the same or similar hydrophobic material as the material of the hydrophobic pattern 200 (e.g., Teflon, polymeric materials such as P or PMMA, PDMS, or Pranic). The present invention is not limited or restricted by the material and properties of the hydrophobic coating 312.

[0130] As described above, the hydrophobic coating 312 can be disposed on the surface of the guide member 310, which allows condensate flowing downward along the surface of the guide member 310 to be absorbed more quickly by the absorber member 300.

[0131] According to the exemplary embodiments of the present invention described above, the beneficial effect of improving comfort while reducing discomfort can be obtained.

[0132] According to an exemplary embodiment of the present invention, the beneficial effect of minimizing the retention of condensate on the contact portion of the thermoelectric module that comes into contact with the object can be obtained, thereby improving comfort.

[0133] Furthermore, according to exemplary embodiments of the present invention, the beneficial effects of minimizing performance degradation of the thermoelectric module and improving energy efficiency can be achieved.

[0134] Furthermore, according to exemplary embodiments of the present invention, the beneficial effects of minimizing condensate leakage to the outside and creating a fresh and comfortable environment can be achieved.
