Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 As shown, a heat dissipation management system for a circulating water-cooled plant factory LED surface light source mainly includes:

[0027] (1) LED panel heat dissipation device, this device mainly replaces the heat energy generated when LED electrons and holes recombine with hot-dip galvanized heat sink to achieve the purpose of heat dissipation.

[0028](2) Temperature measuring instrument. This measuring instrument can be used to measure the temperature of the water inlet and outlet of the LED panel cooling device. It is mainly used to calculate the heat taken away by the water passing through the LED panel cooling device. The measured heat is used to control the outdoor temperature. The speed of the fan achieves the purpose of matching the fan speed to the heat dissipation, and avoids unnecessary energy consumption caused...

Abstract

A circulating water-cooled plant factory LED (light-emitting diode) surface light source heat dissipation management system and method. The system comprises an LED panel heat dissipation device, a controller, a temperature measuring instrument, a heat energy replacement system and a water channel circulating system, the LED panel heat dissipation device is mounted at the back of a lamp panel, the temperature measuring instrument is mounted on a pipeline of the water channel circulating system entering and exiting the heat dissipation device, the water channel circulating system penetrates the heat dissipation device, the temperature measuring instrument acquires the temperature of inlet and outlet water passing the heat dissipation device, and the controller calculates heat in a replacement water channel of the heat energy replacement system according to the temperature of the inlet and outlet water and controls the rotating speed of a radiator fan to perform heat dissipation. Heat energy generated by LEDs can be timely dissipated, the light-emitting efficiency of the LEDs is ensured, and light attenuation rate is reduced. Besides, the heat energy dissipated from the LEDs can be used for heating the indoor environment of a plant factory in heating seasons, the heat energy is timely discharged from the indoor environment in non-heating seasons, and energy consumption for cooling in the non-heating seasons is reduced.

Description

technical field [0001] The invention belongs to the field of intelligent agricultural equipment and energy-saving management, and in particular relates to an adaptive system for realizing heat dissipation management and utilization of LED surface light sources in plant factories by utilizing circulating water cooling and energy consumption management. Background technique [0002] At present, LED (Light Emitting Diode) is an electronic component that converts electrical energy into light energy. Compared with traditional light sources, LED (Light Emitting Diode) has the advantages of small size, light weight, firm structure, low operating voltage, long service life, energy saving and environmental protection. , as the price decreases, it will be the mainstream light source for artificial light-utilizing plant factories in the future. There are various forms of LED light sources, such as point light source, bar light source and surface light source, etc., but in comparison, s...
