Semiconductor thermopile precise temperature control system for ship

Abstract

The invention relates to a semiconductor thermopile precise temperature control system for a ship, which belongs to the technical field of refrigeration and man-machine environment engineering. The system comprises a semiconductor thermopile, a reservoir, a three-way valve, a heat exchanger, a liquid supply pump, a circulating pump, a cooling water pump and a load. A semiconductor thermopile is used as a cold and heat source, a natural cooling branch which is controlled by a three-way valve to be switched on and off is arranged, and the natural cold source is preferentially utilized to achieve energy conservation; the four working modes of thermoelectric refrigeration, natural cooling and thermoelectric refrigeration, natural cooling and semiconductor heating are achieved, and accurate control over the liquid supply temperature is achieved by accurately adjusting the refrigerating capacity or the heating capacity. The thermoelectric refrigeration and natural cooling combined thermal control system has the advantages that the semiconductor thermopile is long in service life, high in reliability, convenient in refrigeration or heating switching and small in size and mass, and the energy-saving performance of the thermoelectric refrigeration system is greatly improved due to the application of the natural cooling technology; the system is suitable for all-weather working environment temperature precision control of light, electricity, microwave and electromagnetic systems for ships and computer rooms.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and man-machine environment engineering, and specifically relates to a system for providing precise temperature control for ship (ship) on-board photoelectric equipment and data room working under wide environmental conditions. Background technique [0002] Ship optoelectronic equipment, data room, etc., all have basic requirements for stable and reliable work in all-weather and wide environmental conditions, and have the characteristics of high heat flux density and frequent changes in heat load, requiring fast response speed and high temperature control accuracy of temperature control devices. The relevant controlled equipment not only needs cooling, but also needs heating when working in cold weather conditions or cold starting.

Problems solved by technology

[0003] The most commonly used precision temperature control system is a vapor compression refrigeration system as a cold and heat source, which has disadvantages such as narrow working temperature range, inconvenient switching between cooling and heating, long temperature stabilization time, and large volume and mass.

For photoelectric detection and infrared camera equipment, the vibration problem of the vapor compression refrigeration system is the bottleneck of the application; the vapor compression refrigeration system has many components, and it is difficult to light and miniaturize; there are many wearing parts, which affects the reliability and maintenance of the environmental control equipment sex
