semiconductor refrigeration devices can be roughly divided into four categories: (1) they are used to cool a certain object or radiate heat to a specific object, which occurs in the field of electronic industry in large numbers; (2) Used for constant temperature, ranging from maintaining constant temperature for individual electronic devices to manufacturing constant temperature tanks and air conditioners; (3) manufacturing complete sets of instruments and equipment, such as environmental experiment boxes, small refrigerators, and various thermophysical testing instruments; (4) Civil products, dual-purpose boxes for refrigeration and baking, cooling and heating fans, etc.
Edit the application of semiconductor refrigeration in this paragraph
(1) Refrigeration of photoelectric devices such as infrared detectors, lasers and photomultiplier tubes in high-tech and military fields
. For example, the semiconducTOr refrigerator of German Micropelt company is very small, only 1 square millimeter, so it can be packaged with laser to.
(2) Application in agriculture
Too high or too low temperature in greenhouse will lead to seedling necrosis, especially some rare plants are more sensitive to the environment, so it is urgent to apply appropriate temperature detection and control system to modern agriculture.
(3) Application in medical field
Semiconductor temperature control system is more widely used in medicine. Such as: high-grade PCR instrument, electrophoresis instrument and some intelligent and accurate temperature-controlled thermostat incubators for protein function research and gene amplification; Used to develop scanning probe microscope with special temperature platform.
(4) Application in the laser field
Laser technology is used for beauty instruments, micro-parts processing, etc., which all generate local heat during work and are cooled by water cooling or micro-refrigerator through a semiconductor refrigerator.
(5) In terms of laboratory equipment
such as microscope camera for experiment [1]? , cold trap, cold box, cold tank, electronic low temperature testing device, various constant temperature and high and low temperature experimental instruments
(6) Application in daily life
Air conditioners, cold and hot dual-purpose boxes, drinking fountains, electronic mailboxes, computers and other electrical appliances. In addition, there are other applications, so I won't mention
the advantages of editing this paragraph of semiconductor refrigeration
the size of semiconductor refrigerator is small, and it can be made into a refrigerator with a volume of less than 1cm; Light weight, micro-refrigerators can often be as small as only a few grams or dozens of grams. There is no mechanical transmission part, no noise in operation and no liquid or gas working medium, so it does not pollute the environment, and the refrigeration parameters are not affected by the spatial direction and gravity, and can work normally under the condition of large mechanical overload; By adjusting the working current, the cooling rate can be easily adjusted; By switching the current direction, the refrigerator can be changed from the cooling state to the heating working state; Fast action speed, long service life and easy control.
