Description

A cultivation rack with a water-cooled LED light source module

technical field

The utility model relates to the field of intelligent agricultural equipment, in particular to a cultivation frame with a water-cooled LED light source module.

Background technique

In a fully enclosed plant factory, electricity is the main cost of production. In the old days, high-pressure sodium lamps or fluorescent lamps were often used as supplementary light for plants, which had the defects of high energy consumption and a large difference between the spectrum and the needs of plants, and it was difficult to ensure the efficient production of facility crops. Moreover, these light sources generate a lot of heat when they work, and if they are too close to the plants, they will "scald". LED, known as the fourth-generation light source, is a solid-state light source, which has the advantages of small size, light weight, energy saving and environmental protection, long life, and small spectral broadening. It has incomparable advantages over traditional light sources. Ideal source of light. More importantly, the LED light source is a cold light source, which radiates less heat when working, and can be irradiated close to the surface of the plant leaves, reducing the irradiation distance and improving the lighting efficiency.

However, as an electro-optical conversion device, the conversion efficiency of LED is only about 30%. The rest of the energy is released as heat. When the junction temperature of the LED chip is too high, there will be problems such as wavelength drift and shortened life, so it is necessary to provide heat dissipation measures for the LED light source. The heat dissipation technology used in traditional LED plant lights mostly installs a radiator behind the LED, and uses natural convection of air or forced convection of a fan to dissipate heat into the environment. However, the plant factory is a closed and constant temperature environment, and a large number of LEDs will inevitably lead to an increase in the indoor temperature. Therefore, cooling methods such as air coolers are needed to make the ambient temperature meet the requirements, and these cooling methods will also greatly increase the overall energy consumption of the plant factory. .
