Electronic heating/cooling pad

Abstract

An electronic heating / cooling pad comprises a pad that is internally provided with cold liquid bearing pipes, a temperature sensor used for temperature measurement and control, a semiconductor heating / cooling device, a pump, a water tank and a water tank cover, and a controller, wherein the semiconductor heating / cooling device comprises an inner heat exchanger, an outer heat exchanger, a heat exchange fan and a semiconductor chip arranged between the inner and the outer heat exchanger, wherein the pump is connected between the pad and the water tank; and a circulation loop bearing cold liquidis formed among the cold liquid bearing pipes in the water tank, the pump and the pad. The electronic heating / cooling pad is characterized in that the inner heat exchanger is inserted in the water tank; the water tank is hermetically connected with the inner heat exchanger; and baffles respectively alternately join right and left fins of the inner heat exchanger so that the water tank forms a circuitously continuous cold liquid bearing passage in S shape. With an infusion pump, the semiconductor heating / cooling device and the like, the electronic heating / cooling pad can not only cool, but also heat, with small power consumption, low cost and temperature adjustment to meet the requirement of people for different temperatures. The baffles of the water tank can fully improve heat exchange effect and efficiency as well.

Description

technical field [0001] The invention relates to the technical field of semiconductor refrigeration, and more specifically, relates to an electronic cooling and heating pad. Background technique [0002] The electric blanket is a kind of contact electric heating appliance. It weaves or sews the special flexible cable-type electric heating element with up to the insulation performance into the blanket in the shape of a coil snake, and it emits heat when it is energized. With the development of science and technology, it is found that the traditional electric blanket can produce 100-190 milligauss of electromagnetic wave radiation when it is working, which is dozens of times higher than the standard regulation that the electromagnetic wave radiation intensity of the environment where people live and live should not be higher than 2 milligauss. More than one hundred times, it will generate strong induction electricity while generating heat, which will seriously damage human heal...

Problems solved by technology

However, most of the water tanks of semiconductor cooling and heating water bed blankets are currently unreasonably designed. The cold water and hot water used for circulation in the water tank are mixed together, which makes the heat exchange efficiency not high, and the effect of cooling or heating is not good. There is indeed further improvement. necessary
