A mute plant tissue incubator

Abstract

A mute plant tissue incubator is disclosed. The incubator includes a tank and a control unit disposed in the tank. A plurality of separating plates used for accommodating plant tissue culture vesselsare disposed in the tank. Bottoms of the separating plates are provided with lighting sources. The separating plates are heat insulating plates insides of which are provided with heat conductors. Theheat conductors are connected to cold ends of semiconductor refrigerating sheets. Hot ends of the semiconductor refrigerating sheets are provided with cooling fins. The lighting sources and the semiconductor refrigerating sheets are electrically connected to the control unit. The multifunctional plant tissue incubator which is simple in structure, mute and free of vibration is provided.

Problems solved by technology

[0002] With the development and progress of material science, new thermal insulation materials are constantly appearing, but no thermal insulation material can achieve 100% thermal insulation, and its thermal insulation coefficient will not be zero. As time goes by, the heat will Continuously pass from one side of the material to the other and accumulate

But in actual production, sometimes we need absolute heat insulation. For example, in plant tissue culture, in order to improve space utilization, the tissue culture rack is designed as multi-layer, sterile seedlings are placed on the laminate, and lighting sources are placed under the laminate. , to illuminate the sterile seedlings cultivated in the lower layer, because the heat dissipation of the lamp tube under the layer makes the temperature of the layer slightly higher than the ambient temperature, and the temperature of the bottom of the culture vessel placed on the layer is slightly higher than the temperature of the cover and wall of the culture vessel , causing the water vapor on the cover and wall of the culture vessel to condense into water droplets, and then drip onto the medium and cultured seedlings

On the one hand, the water condenses out of the medium, which will change the composition of the medium; on the other hand, the condensed water drops will flood the cultured callus and seedlings after flowing down on the medium, causing growth obstacles and vitrification of regenerated shoots. , resulting in culture failure

[0003] In order to prevent the generation of condensed water, it is necessary to adopt a method to quickly transfer the heat generated by the lighting source to the atmosphere. At present, most of the air-cooled or water-cooled methods used on the market use fast-flowing fluid to transfer the heat generated by the lighting source to the atmosphere. It is quickly transmitted to the atmosphere. During the operation, the motor is needed to increase the flow rate of the fluid. However, during the operation of the motor, it will be accompanied by vibration and noise, which is not good for the growth of plant tissue.
