For example, for cooling and heating boxes, conventionally, one or two thermoelectric modules of about 40 mm square are used. Since the thermoelectric module itself is small, it will be installed in a limited part of the box. Therefore, in order to keep the inside of the box at around 5, the temperature of the thermoelectric module itself must be lowered to about -5 and the box must be cooled or heated for a longer time due to the heat conduction of the aluminum-copper plate.

Eight thermoelectric modules 31 are arranged on a thin phosphor blue plate 35 having a thickness of 0.4 mm, a length of 150 mm, and a width of 40 mm.
- the phosphor blue plate used as the sheet is thin and therefore flexible, so if you use it instead of a headband, for example, you can expect the effect of studying on the heat of the head and feet.
- the density when the thermoelectric module 31 is mounted on the sheet 35 is expressed by the ratio of the area of the thermoelectric semiconductor element to the substantial area of the sheet. It is preferable to use 3 to 55%. If the density is more than 55%, the flexibility will be lost, and if it is less than 3%, the effect will not be seen in terms of thermal efficiency.
- the substantial area is defined as a portion where this sheet is used for another purpose (for example, a portion connecting band 36 to the sheet in FIG. 21). Etc.) is excluded.
- the optimum density of the thermoelectric module 31 mounted on the sheet 35 is determined in consideration of the cooling Z heating efficiency and the flexibility.
- thermoelectric element of the present invention is based on a thermoelectric chip unit.
- thermoelectric elements have a higher temperature on one of the upper and lower surfaces, and a lower temperature on the other.
- the thermoelectric chip unit which is the basis of the present invention, has a structure in which a thermoelectric semiconductor element is fitted into a chip substrate.
- This chip substrate plays a role of separation. That is, in a normal thermoelectric module, convection of air occurs on the upper and lower surfaces thereof, and the thermal efficiency decreases, but in the thermoelectric element of the present invention, the chip substrate suppresses the convection of air on the upper and lower surfaces. Thermal efficiency is improving.
- thermoelectric element based on the present invention has an advantage that since the chip substrate serving as a separator has flexibility, it absorbs strain due to stress and has a large resistance to repeated stress strain.
- thermoelectric unit, thermoelectric module and thermoelectric sheet of the present invention described above can be used for a cooling / heating apparatus.
- An example of its application is in sporting, health or medical equipment used for heating or cooling in the form of a belt.
- Another application is for cooling Z-heating equipment for outside door products.
- a specific example is a box for cooling and heating. The effect of using the cooling / heating element of the present invention in this box has already been described.
- the third application is for agriculture and fisheries. Specifically, temperature control of a water tank or a pot.
- thermoelectric sheet of the present invention has a feature of flexibility, it can be applied to objects having a complicated shape without any problem. For example, by winding this thermoelectric sheet around a cylindrical object such as a shaft or a bearing, it can function sufficiently as a cooling / heating device.
- a thermoelectric sheet can be wound around the pipe to control the temperature of the fluid flowing in the pipe, and if the fluid in the pipe has a relatively high melting point, the fluid is cooled when the temperature of the pipe decreases. It will solidify and cause blockage in the pipe. In such a case, it is possible to transport the fluid without solidifying the fluid by keeping the thermoelectric sheet of the present invention warm. In addition, it is used to cool motors and various machine tools. I can do it.
- the fifth application is clothing.
- clothing for lasers clothing for cold weather in art doors, cold weather work clothes for freezer work, heating or cooling work clothes for extremely cold or hot places, and even firefighting clothes. Appears.
