Description

  The present invention relates to an air duct structure for a gas temperature control device that adjusts the temperature of a gas by utilizing the Peltier effect of a thermoelectric element.

  The humidity control apparatus described in Patent Document 1 cools air introduced from one side by the endothermic action of a Peltier element, which is a thermoelectric element, and simultaneously heats air introduced from the other side by its heat dissipation action. In order to actually operate the tuned humidity device, a duct for introducing air and a damper for switching the flow of air as described above are indispensable. Therefore, the air supply / exhaust device described in Patent Document 2 forms a thermoelectric unit in which a Peltier element is sandwiched between heat absorbing fins and heat radiating fins, and the thermoelectric unit is rotatable with respect to a plurality of ducts arranged around the thermoelectric unit. The duct that guides air to the thermoelectric unit and the duct that exhausts air from the thermoelectric unit can be selected from the plurality of ducts.

  However, increasing the number of Peltier elements in order to improve the performance of the thermoelectric unit or increasing the size of the heat sink connected to the Peltier element increases the size of the air supply / exhaust device by the amount of space required to rotate the thermoelectric unit. Or increase the weight. Further, if the distance between the fins is reduced in order to add fins to the heat sink or the depth of the fins is increased in the gas flow direction, the pressure loss of the gas flowing between the fins becomes significant. For this reason, there exists a problem that the output of the air blower etc. for supplying gas to a duct increases unnecessarily.

Arrows W, L, and T in the figure respectively indicate the width direction, the length direction, and the thickness direction of the box 7.

  As shown in FIGS. 6 and 7, the thermoelectric unit 17 includes a Peltier element 29 having a heat dissipation surface 27 opposite to the heat absorption surface 25, a heat absorption fin 33 joined to the heat absorption surface 25 via a fin base 31, and heat dissipation. It is sandwiched between the heat dissipating fin 35 joined to the surface 27 via the fin base 31. The endothermic fins 33 are corrugated fins obtained by plastically deforming an aluminum thin plate into a corrugated shape. A hygroscopic agent such as silica gel may be fixed on the surface of the heat absorbing fins 33. The heat radiating fins 35 are the same as the heat absorbing fins 33.

  The support 19 has a rectangular frame formed of vertical members 37 and 39 and two cross members 41, and an opening 43 through which a gas such as air can pass in the length direction is provided inside thereof. The support 19 is inserted into the box 7 from the insertion port 47 on the front surface 45 of the box 7, and can move freely in the width direction with respect to the box 7. The insertion opening 47 is formed at a position where the front surface 45 and the back surface 49 of the box 7 face each other. A plurality of thermoelectric units 17 are positioned in the opening 43 of the support 19, and three endothermic air passages 51, 53, 55 and three heat radiating air passages 57, 59, 61 are located between the Peltier elements 29. It is divided into and.

  Further, the plurality of thermoelectric units 17 are arranged in the width direction across the direction in which the gas passes through the opening 43 of the support body 19, and in this arrangement order, the respective heat absorption fins 33 are directed to the vertical members 37, and The posture in which each endothermic fin 33 is directed to the vertical member 39 is alternately changed. The endothermic air passages 51 and 53 are regions where the thermoelectric units 17 adjacent to each other in the width direction oppose the respective endothermic fins 33. The endothermic air passage 55 is a region between the longitudinal member 39 and the Peltier element 29 of the thermoelectric unit 17 facing the longitudinal member 39. The heat radiating air passage 57 is a region between the vertical member 37 and the Peltier element 29 of the thermoelectric unit 17 facing the vertical member 37. The heat radiation air paths 59 and 61 are regions where the thermoelectric units 17 adjacent to each other in the width direction oppose the heat radiation fins 35 to each other.

  The box 7 includes two divided plates 63 and twelve flow dividing plates 65. The dividing plate 63 divides the inside of the one end portion 3 and the other end portion 5 of the box 7 into two in the thickness direction, so that the first and second introduction paths 67 and 69 and the first and second lead-outs are obtained. The paths 71 and 73 are formed. The flow dividing plates 65 are arranged six by six between the restriction plate 21 and the support body 19 and between the support body 19 and the restriction plate 23, and partition the inside of the box 7 into a plurality of branch flow paths 75. The outlets 13 and 15 are provided with a fan 77 for sucking gas from the first and second outlet paths 71 and 73 and discharging it to the outside of the box 7.

  The restriction plates 21 and 23 are fixed to the box 7. The restriction plate 21 has three introduction holes 79, 81, 83 and four lead-out holes 85, 87, 89, 91. The lead-out holes 85, 87, 89, 91 are different in position in the thickness direction with respect to the introduction holes 79, 81, 83. Further, the positions of the introduction holes 79, 81, 83 and the outlet holes 85, 87, 89, 91 in the width direction respectively correspond to the seven branch channels 75 appearing on the right side of FIG. The restriction plate 23 forms four introduction holes 790, 810, 830, and 930 and three lead-out holes 850, 870, and 890. With respect to the introduction holes 790, 810, 830, and 930, the lead-out holes 850, 870, and 890 have different positions in the thickness direction. Further, the positions in the width direction of the introduction holes 790, 810, 830, and 930 and the lead-out holes 850, 870, and 890 respectively match the seven branch channels 75 that appear on the left side of FIG.

  When the support 19 is in the position shown in FIG. 3, the endothermic air passages 51, 53, and 55 of the support 19 are aligned with the introduction holes 79, 81, and 83 of the restriction plate 21, respectively, as shown in FIG. 8. The heat radiating air passages 57, 59, 61 of the support body 19 respectively match the outlet holes 85, 87, 89 of the restriction plate 21. The outlet hole 91 of the restriction plate 21 is blocked from the first outlet path 71 by the vertical member 39. Further, the heat radiating air passages 57, 59, 61 of the support body 19 respectively match the introduction holes 790, 810, 830 of the restriction plate 23, and the heat absorption air passages 51, 53, 55 of the support body 19 are arranged on the restriction plate 23. It corresponds to the lead-out holes 850, 870, and 890, respectively. The introduction hole 930 of the restriction plate 23 is blocked from the second lead-out path 73 by the vertical member 39.

  In this state, a current is supplied to the Peltier element 29 so that heat is transferred from the heat absorbing surface 25 to the heat radiating surface 27. When the two fans 77 are activated, gas flows as shown by arrows I and X in FIG. The figure shows a concept focusing only on the gas passing through the endothermic air passage 53 and the heat radiating air passage 59. The actual gas flow is as follows.

  That is, the gas is guided from the outside of the box 7 to the first introduction path 67 through the introduction port 9, and the introduction holes 79, 81, 83 of the restriction plate 21, the endothermic air passages 51, 53, 55, and the restriction plate 23. The lead-out holes 850, 870, and 890 pass through the lead-out holes 850, reach the second lead-out path 73, and are led out from the lead-out port 15 to the outside of the box 7. On the other hand, the gas guided from the introduction port 11 to the second introduction path 69 is introduced into the introduction holes 790, 810, 830 of the restriction plate 23, the radiating air passages 57, 59, 61, and the lead-out holes 85, 87, It passes through 89 and reaches the first lead-out path 71, and is led out of the box 7 from the lead-out port 13.

  As described above, heat exchange is simultaneously performed between the gas passing through the endothermic air passages 51, 53, and 55 and the endothermic fins 33 of all the thermoelectric units 17, so that the air guide passage structure 1 is a gas. Can be effectively cooled and discharged from the outlets 13 and 15. Moreover, since heat exchange is simultaneously performed between the gas passing through the heat radiating air passages 57, 59, and 61 and the heat radiating fins 35 of all the thermoelectric units 17 as described above, the air guide passage structure 1 Can efficiently dissipate heat from the heat radiation surface 27 of the Peltier element 29.

  The air guide path structure 1 can perform batch processing in which the above-described operation and its pause are repeated at a constant period. Thereby, the air guide path structure 1 can adjust the temperature and humidity of gas continuously. Also, the temperature and humidity can be controlled as desired by increasing or decreasing the batch processing cycle. For example, if the cycle of batch processing is shortened, the dehumidifying capacity increases, but the cooling capacity (sensible heat treatment) decreases. Conversely, if the cycle of the batch process is lengthened, the dehumidifying capacity is lowered, but the cooling capacity is increased. Up to this point, the dehumidifying and cooling by the air guide structure 1 has been described. However, if current is supplied to the Peltier element 29 so that heat is transferred from the heat radiation surface 27 to the heat absorption surface 25, humidification heating can be performed.

  Further, when silica gel is fixed to the heat-absorbing fins 33 and the heat-radiating fins 35, the water vapor contained in the gas can be absorbed into the silica gel of the heat-absorbing fins 33 when the air guide path structure 1 performs dehumidification cooling. When the silica gel reaches a saturated state, when current is supplied to the Peltier element 29 so that heat is transferred from the heat radiating surface 27 to the heat absorbing surface 25, the air guide path structure 1 has the heat absorbing air paths 51, 53, 55. It is possible to dissipate the heat of the heat dissipation surface 27 of the Peltier element 29 to the gas passing through and evaporate the moisture absorbed by the silica gel of the heat absorption fins 33.

  Further, the air guide path structure 1 includes a moving means 95 that moves the support 19 in the width direction with respect to the regulating plates 21 and 23. The moving means 95 connects the support body 19 via a connecting member 99 to a piston rod 97 of an air cylinder or a hydraulic cylinder. FIG. 1 shows a state in which the moving means 95 has moved the piston rod 97 forward.

  When the moving means 95 moves the piston rod 97 backward, as shown in FIG. 10, the heat radiating air passages 57, 59, 61 of the support body 19 are respectively aligned with the introduction holes 79, 81, 83 of the restriction plate 21, and are supported. The endothermic air passages 51, 53, and 55 of the body 19 match the outlet holes 87, 89, and 91 of the restriction plate 21, respectively. The outlet hole 85 of the restriction plate 21 is blocked from the first outlet path 71 by the vertical member 37. Further, the endothermic air passages 51, 53, and 55 of the support body 19 respectively match the introduction holes 810, 830, and 930 of the restriction plate 23, and the radiating air passages 57, 59, and 61 of the support body 19 correspond to the restriction plate 23. It corresponds to the lead-out holes 850, 870, and 890, respectively. The outlet hole 850 of the restriction plate 23 is blocked from the first outlet path 71 by the vertical member 37.

  In this state, a current is supplied to the Peltier element 29 so that heat is transferred from the heat absorbing surface 25 to the heat radiating surface 27. When the two fans 77 are activated, gas flows as shown by arrows I and X in FIG. This figure represents the concept focusing only on the gas passing through the endothermic air passage 53 and the heat radiating air passage 59. The actual gas flow is as follows.

  That is, the gas is guided from the outside of the box 7 to the first introduction path 67 through the introduction port 9, and the introduction holes 79, 81, 83 of the restriction plate 21, the radiating air passages 57, 59, 61, and the restriction plate 23. The lead-out holes 850, 870, and 890 pass through the lead-out holes 850, reach the second lead-out path 73, and are led out from the lead-out port 15 to the outside of the box 7. On the other hand, the gas led from the introduction port 11 to the second introduction path 69 is introduced into the introduction holes 810, 830, 930 of the restriction plate 23, the endothermic air passages 51, 53, 55, and the lead-out holes 85, 87, It passes through 89 and reaches the first lead-out path 71, and is led out of the box 7 from the lead-out port 13.

  According to the air guide structure 1 described above, a damper or the like for switching the flow of the gas guided to the thermoelectric unit 17 is unnecessary, and a space for rotating the thermoelectric unit 17 with respect to the air flow or the like through which the gas flows. Is unnecessary. For this reason, since the box 7 need only be large enough to accommodate the thermoelectric unit 17, the entire air guide path structure 1 can be reduced in size and weight.

  Furthermore, by increasing / decreasing the number of thermoelectric units 17, it is possible to adjust the performance of cooling the gas passing through the heat radiating air passage and the heat absorbing air passage, or the amount of heat released to the gas. In this case, if the plurality of thermoelectric units 17 are arranged in the width direction in which the support 19 moves, it is not necessary to increase the distance that the gas flows along the heat absorption fins 33 and the heat radiation fins 35 of the individual thermoelectric units 17. Gas pressure loss can be suppressed.

  Further, a sealing material for keeping the airtightness in an appropriate position of the box 7 may be provided. As shown in FIG. 12, an elastic body 101 having a triangular cross-sectional shape and extending in the thickness direction is attached to the edge of the insertion opening 47 formed on the front surface 45 of the box 7, and an elastic body 103 similar to the elastic body 101 is attached. Alternatively, it may be attached to the vertical member 37 of the support 19. The figure shows an example in which the elastic body 103 is in close contact with the elastic body 101 when the support body 19 advances in the direction of arrow F.

  Next, the difference from the air guide path structure 1 is demonstrated about the 2nd Embodiment of this invention. The drawings refer to FIGS. 13 to 16 unless otherwise specified.

  The air guide structure 10 according to the second embodiment fixes the support 19 to the box 7, and the restricting plates 21 and 23 from the slit-shaped insertion port 47 formed on the front surface 45 of the box 7. 7 is inserted inside. The two regulating plates 21 and 23 are joined to each other by a connecting member 96 and are connected to the piston rod 97 of the moving means 95 via the connecting member 96. In the restricting plate 21, the outer introduction hole 107 and the inner introduction hole 109 are combined to form an introduction hole 79, and the outer introduction hole 111 and the inner introduction hole 113 are combined to form an introduction hole 83. In the restriction plate 23, the outer outlet hole 115 and the inner outlet hole 117 are combined to form a outlet hole 850, and the outer outlet hole 119 and the inner outlet hole 121 are combined to form a outlet hole 890.

  When the moving means 95 advances the piston rod 97 in the direction of arrow F and the restricting plates 21 and 23 are in the positions shown in FIG. 15, the restricting plate 21 has the outer introduction hole 107 and the outlet hole 85 formed in the box 7. The inner introduction hole 109 is aligned with the heat radiating air passage 57. On the other hand, the restricting plate 23 causes the introduction hole 790 and the outer lead-out hole 115 to protrude from the front surface 45 of the box 7, but the inner lead-out hole 117 is matched with the heat radiating air passage 57.

  Alternatively, when the moving means 95 moves the piston rod 97 backward in the arrow B direction, the regulating plate 21 causes the outer introduction hole 111 and the outlet hole 91 to protrude from the back surface 49 of the box 7, but the inner introduction hole 113 is Match with the endothermic air passage 55. On the other hand, the restricting plate 23 causes the introduction hole 930 and the outer lead-out hole 119 to protrude from the back surface 49 of the box 7, but makes the inner lead-out hole 121 match the endothermic air passage 55.

  Moreover, you may attach the elastic body 103 shown in FIG. In this case, the elastic body 103 is attached to a position passing between the outer introduction hole 107 and the inner introduction hole 109 of the regulation plate 21 and a position passing through the outer introduction hole 111 and the inner introduction hole 113. Further, the elastic body 103 is attached to a position passing between the outer lead-out hole 115 and the inner lead-out hole 117 of the restriction plate 23 and a position passing through the outer lead-out hole 119 and the inner lead-out hole 121.

  FIG. 17 shows an example in which the indoor temperature is adjusted using a modification of the air guide structure 1. The moving means is omitted, and the support 19 and the regulation plates 21 and 23 are fixed to the box 7. The mutual arrangement of the support 19 and the regulation plates 21 and 23 is as already described with reference to FIG. Reference numeral 123 denotes a wall that blocks the room from the outside. The indoor air reaches the inlet 9 of the air guide path structure 1 installed outside the room through a duct 126 that opens the air inlet 125 to the room. The inlet port 11 and the outlet port 13 of the air guide structure 1 are open to the outdoors.

  When the room is cooled, current is supplied to the Peltier element 29 of the air guide path structure 1 so that heat is transferred from the heat absorption surface 25 to the heat dissipation surface 27, and the two fans 77 are activated. Thereby, the indoor air passes through the endothermic air passages 51, 53, and 55 from the inlet 9 and further circulates from the outlet 15 into the room. The outdoor air passes through the heat radiating air passages 57, 59, 61 from the inlet 11 and is discharged from the outlet 13. When the room is heated, current is supplied to the Peltier element 29 of the air guide path structure 1 so that heat is transferred from the heat radiation surface 27 to the heat absorption surface 25, and the indoor air is circulated as described above. .

  FIG. 18 shows an example of adjusting indoor ventilation and indoor temperature using a further modification of the air guide structure 1. In this case, the end opening 127 is released to the box 7 and the other end of the box 7 is fully opened toward the room. The dividing plate 63, the flow dividing plate 65, and the regulating plate 23 appearing on the left side of FIG. 1 are omitted, and the regulating plate 21 is fixed to the box 7. The fan 78 provided in the introduction port 9 blows air from the inside of the box 7 to the duct 130 in which the ejection port 129 is released indoors.

  When the room is cooled, current is supplied to the Peltier element 29 of the air guide path structure 1 so that heat is transferred from the heat absorbing surface 25 to the heat radiating surface 27 and the two fans 77 and 78 are activated. Air flows into the endothermic air passages 51, 53, and 55 and the heat radiating air passages 57, 59, and 61 simultaneously from the end opening 127. Then, the air flowing into the endothermic air passages 51, 53, 55 is cooled, passes through the introduction holes 79, 81, 83 of the regulation plate 21, and circulates from the introduction port 9 into the room through the duct 130. The air flowing into the heat radiating air passages 57, 59, 61 is exhausted from the outlet 13 through the outlet holes 85, 87, 89 of the restriction plate 21 to the outside of the room.

  When the room is heated, an electric current is supplied to the Peltier element 29 of the air guide structure 1 so that heat is transferred from the heat radiation surface 27 to the heat absorption surface 25. Thereby, the air flowing into the endothermic air passages 51, 53, 55 is heated, passes through the introduction holes 79, 81, 83 of the regulation plate 21, and circulates from the introduction port 9 into the room through the duct 130. The air flowing into the heat radiating air passages 57, 59, 61 is exhausted from the outlet 13 to the outside through the outlet holes 85, 87, 89 of the restriction plate 21.

  Alternatively, the restriction plate 21 may be attached to the box 7 so as to be movable in the width direction. In this case, if the introduction holes 79, 81, 83 and the outlet holes 85, 87, 89 of the regulation plate 21 are matched with the heat radiation air paths 57, 59, 61 and the heat absorption air paths 51, 53, 55, respectively, The room can be heated as follows without switching the current. That is, the air heated by the heat radiating air passages 57, 59, 61 in a state in which a current is supplied to the Peltier element 29 in the same manner as when performing the above-mentioned cooling passes through the introduction holes 79, 81, 83 and is introduced. It circulates from the port 9 through the duct 130 into the room. The air flowing into the endothermic air passages 51, 53, 55 is exhausted from the outlet 13 through the outlet holes 85, 87, 89 to the outside of the room.

  It should be noted that the present invention can be carried out in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. For example, warm air or cold air may be blown into either the endothermic air path or the heat radiating air path, and a temperature difference may be generated between the heat absorbing surface 25 and the heat radiating surface 27 of the Peltier element 29. Thereby, an electromotive force can be generated in the Peltier element 29. Further, the plurality of flow dividing channels 75 are not essential elements, and even if the flow dividing plate 65 is omitted and the two regulating plates 21 and 23 are brought close to the support body 19, the implementation of the present invention is not hindered.

  The present invention can be used to cool an electrical component or adjust the temperature in a room.
