Electronic refrigerating and temperature regulating apparatus

Abstract

An electronic refrigerating and temperature-controlling apparatus consists of a thermal insulating cover or door, an insulation body, a refrigerating assembly, a controller, an operating panel, a receptacle set, and a shell. The thermal insulating cover / door is formed with two plates with thermal insulating materials between them. The insulation body is formed with an outer chamber, where the refrigerating assembly and controller are located, and a circulating chamber, where temperature-regulating liquid is filled for thermal insulation and guarantee safety at high temperature when it is empty. It is equipped with semiconductor refrigerating component for protecting environment. It works durably in a range of -30deg.C to 50deg.C and can be used for bio-materials storing device or facility in a laboratory as well as a terminal in network. The working solution is stored in a closed thermal insulating body so as not to be volatile.

Description

technical field [0001] The invention belongs to electronic refrigeration and temperature control equipment. Background technique [0002] The currently used refrigeration and temperature control equipment can be divided into two categories: chemical refrigeration and electronic refrigeration according to their working mechanism. Chemical refrigerant refrigeration has always been considered to be improved or replaced due to its damage to the ozone layer and environmental pollution. Electronic refrigeration has been widely concerned because it has no volatile gas and is environmentally friendly. However, for a long time, electronic refrigeration has the disadvantages of poor performance and low refrigeration capacity. The low temperature thermostat technology with usable characteristics has become a research direction. After literature search, it was found that an "electronic stepless thermostat" (China Patent No.: ZL02110529.4), which is characterized by an all-electronic sy...

[0002] The currently used refrigeration and temperature control equipment can be divided into two categories: chemical refrigeration and electronic refrigeration according to their working mechanism. Chemical refrigerant refrigeration has always been considered to be improved or replaced due to its damage to the ozone layer and environmental pollution. Electronic refrigeration has been widely concerned because it has no volatile gas and is environmentally friendly. However, for a long time, electronic refrigeration has the disadvantages of poor performance and low refrigeration capacity. The low-temperature constant temperature box technology with usable characteristics has become a research direction

This patent hopes to achieve the purpose of electronic stepless temperature regulation through the composite Peltier effect, but the realization of the cabinet is small, the performance of maintaining the temperature is low and the frequent startup, and the refrigeration performance cannot reach the low temperature and constant temperature environment below 0 °C
