Description

The apparatus for thermal efficiency increase of thermocouple module

The present invention relates to a device for increasing the thermal efficiency of the thermoelectric module, and when the direct current is energized, the Peltier effect separates the temperature in both up and down directions, thereby minimizing the occurrence of temperature deviation, so that the upper and lower side heats are properly radiated or transferred. The present invention relates to an apparatus for increasing the thermal efficiency of a thermoelectric module used in an air conditioner for improving the structure of a thermoelectric module.

The thermoelectric module is a heat and electricity exchange system that can simultaneously perform cooling or heating using the Peltier effect, and can be easily switched between cooling and heating through pole switching.

Such thermoelectric modules have a small volume, fast and excellent cooling effect, and thus are widely used as next generation cooling methods to replace conventional compressor cooling methods. In particular, when the system requires stability, such as electronic devices, but the operating space is small, noise prevention, it is used when the temperature control must be easily possible.

Such a thermoelectric module is formed by arranging n-type and p-type thermoelectric elements between insulating substrates. When the p-type device and the n-type device are bonded to a metal electrode, and a direct current is flowed so that the poles of the bipolar branch of the circuit become-and +, the holes in the p-type device are -poles according to the Peltier effect. The electrons inside are attracted to the opposite pole. At this time, since both the hole and the electron have heat from the upper p-n junction electrode and move to the lower quantum terminal electrode, the upper junction is cooled to absorb heat from the surroundings, and the lower quantum terminal emits heat. If you reverse the flow of current, the opposite effect occurs. Therefore, the thermoelectric module is a device that can be used for cooling or heating.

However, when the thermoelectric module is attached to the cooling or heating object of the thermoelectric module or is exposed to the cooling or heating object space, the heat sink is attached to the other side of the thermoelectric module to be used for heat exchange and the arrangement and structure of the thermoelectric module. There are many differences in thermal efficiency, and there have been many studies to improve it.

For example, Korean Patent Laid-Open Publication No. 2001-68353 discloses a ceramic substrate and a lower copper electrode formed on the ceramic substrate at predetermined intervals, a thermocouple formed on the lower copper electrode, and a copper heat pipe formed on the thermocouple. It is composed of a thermoelectric cooling module is formed so that the heat pipe can perform the electrode function and the heat radiation function of the thermocouple at the same time,

A technique of manufacturing a thermoelectric module by arranging the cross bars in parallel with each other, then separating the rods and placing the second substrate on the elements and fixing the elements is described.

Korean Patent Publication No. 2002-19786 discloses a thermoelectric module in which a temperature sensor is integrally attached,

The prior art as described above has a problem that the efficacy of the thermoelectric module is hampered by contacting the thermoelectric module does not properly radiate or heat the upper and lower side heat separated during heat exchange.
