A circulating medium heating and cooling semiconductor temperature control device

Abstract

The invention belongs to the technical field of heating and refrigerating temperature control and particularly relates to a semi-conductor temperature control device for heating and refrigerating by using a circulating medium. The temperature control device is composed of a medium circulating system and a temperature control system. Components comprise a heat insulation container, the circulating medium, a circulating driving pump, a flow controller, a heat exchanging plate, a semi-conductor refrigerating plate, a heat / cold dissipating component, a digital display temperature control instrument and a direct-current power supply system. The device has the capacity for controlling external system temperature, can achieve program temperature rising and dropping operation and constant-temperature operation in a wide temperature interval, supports remote monitoring, and meets simple and complex temperature control requirements in scientific research and production. The flowing medium is used in a circulation mode, resources can be saved, noise is avoided during work, the device is easy to miniaturize, and good medium and low temperature control environments can be provided for scientific research and production in the fields of chemistry, chemical engineering, materials, food, medicine, electronics and the like.

Description

technical field [0001] The invention belongs to the technical field of heating and cooling temperature control, and in particular relates to a device for controlling the temperature of external equipment by using a circulating medium and a semiconductor refrigeration element. Background technique [0002] Heating and refrigeration are important basic operations in scientific research and production in many fields, the purpose is to control or adjust the temperature of materials or equipment. According to the acquisition of heat (cold) energy, heating and cooling can be divided into two categories: direct and indirect, and each category has huge branches. In the heating operation, direct heat source heating is to directly add heat energy to the material, such as electric current heating and solar radiation heating. There are many direct heating methods such as chemical heating, electric heating (resistance heating, induction heating, arc heating, electron beam heating, infra...

Problems solved by technology

However, most of the above-mentioned inventions use semiconductor refrigeration elements to directly heat or cool, and a few combine the two functions. At the same time, the equipment does not need complex temperature control, and is not suitable for complex temperature control of external systems.
