Embodiment Construction

[0045] 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.

[0046] 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 invention relates to a mobile hybrid cloud chamber capable of continuously providing supercooled fog, comprising: a cloud chamber cavity with a thermal insulation layer, a temperature sensing element and a cooling system inside; There is a refrigerant interlayer in between, in which there are evaporation tubes of the refrigeration system, electric heaters and temperature sensing elements; there is a supercooling slit between the cloud chamber tube and the jacket layer, from the bottom of the supercooling slit to the outer wall of the cloud chamber cavity A mist pipe runs through it, and a liquid discharge port is opened at the bottom of the refrigerant interlayer, and a sewage pipe is connected to the bottom of the cloud chamber to penetrate into the heat insulation layer, and the sewage pipes are respectively passed out of the cloud chamber through a tee; installed in the cloud chamber Ice crystal receiving device; cover a transparent cover plate on the top of the cloud chamber cavity, open a sample injection port and socket on the cover plate, and set a rotatable handle, the shaft end of which is fixed under the heat capacity plate . The device can realize the continuous or intermittent supply of supercooled mist, so as to ensure that the activation of ice nuclei and the growth of ice crystals injected into the cloud chamber have sufficient water vapor supply all the time.

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...
