Embodiment Construction

[0047] refer to figure 2 , making a 15-liter mobile hybrid cloud chamber device, the cloud chamber negative temperature of the present embodiment still adopts the refrigeration system of the second generation cloud chamber. Tube 4, condenser 24, thermostat 28 and refrigerant constitute, are installed in the bottom of cloud chamber chamber 1, and box body foot is equipped with 4 casters 25.

[0048] The cloud chamber cavity 1 is made of a box with a volume of about 175 liters as the outer shell. A heat insulating layer 2 is arranged on the inner wall of the box; The interior is filled with a mixture of ethylene glycol and water as a refrigerant. If the refrigerant crystallizes as the temperature decreases, the heat conduction between the evaporator tube and the refrigerant will be greatly reduced, making the cloud chamber unable to continue cooling down. Therefore, the prepared refrigerant must not freeze within the ice nucleus activation temperature range to ensure good heat...

Abstract

The mobile mixing cloud chamber capable of providing supercooled fog includes cloud chamber cavity with heat insulating layer, inside temperature sensing element and refrigerating system; inner cloud chamber barrel inside the cloud chamber cavity; sandwiched refrigerant layer between the inner barrel and the heat insulating layer, with liquid exhaust port in the bottom and for the evaporating tube of the refrigerating system, electric heater and temperature sensing element to be set inside; supercooled slot between the inner cloud chamber barrel and the sandwiched layer and with fog tube penetrating the bottom of the slot and the outer wall of the cloud chamber cavity; drainage pipe penetrating from the inner cloud chamber barrel and through the heat insulating layer and tee tube to outside the cloud chamber cavity; ice crystal receptor inside the inner cloud chamber barrel; and rotary handle.

Description

technical field [0001] The invention relates to a basic equipment for cloud physics and weather modification research, in particular to a mobile hybrid cloud chamber which can continuously provide supercooled fog for studying ice nucleation process and cloud catalyst for weather modification experiments. Background technique [0002] The cloud chamber is an important device used in the field of weather modification to study ice nucleation process and cloud catalyst. With the widespread development of artificial weather modification operations, in response to the needs of the development of catalytic tools and cloud catalysts, my country has successively built several cloud chambers with different functions, of which the volume is 96m 3 and 2m 3 Isothermal cloud chambers are large and medium-sized fixed cloud chambers, which can be used for multiple cloud physics experiments, and those mobile hybrid cloud chambers of several liters to tens of liters are mainly used for the o...
