Description

Technical Field

[0001] This invention relates to the field of large cloud chamber technology for natural cloud formation and rainmaking, specifically a cloud chamber for cloud formation and rainmaking with adjustable angles of cold and warm fronts. Background Technology

[0002] Cloud chambers are the core equipment for conducting indoor experiments on cloud and fog physics and artificial weather modification. Currently, the most widely used type is the inflatable cloud chamber, which relies on the warm air mass to rise in a low-pressure environment, expand adiabatically, and cool down. During the ascent, the warm air mass rises continuously, and its temperature decreases continuously, causing water vapor to condense and form fog droplets. This type of cloud chamber is technically mature, its parameters are easy to control, and it can stably achieve cloud and fog generation. It is suitable for basic microscopic experiments such as initial nucleation of fog droplets.

[0003] However, the formation of clouds and fog into precipitation is not as described above. In nature, the main way clouds and fog form and cause precipitation is through the convergence of cold and warm air masses to form a front. The warm air mass is cooled by the influence of the cold air mass, and water vapor is released to form clouds and fog, which then develop into precipitation. The cooling mechanism is the heat exchange at the interface between the cold and warm air masses, which is different from adiabatic expansion cooling. Existing cloud chambers are difficult to simulate the frontal environment where cold and warm air masses converge. The dynamic conditions and thermodynamic processes of cloud formation and precipitation deviate significantly from real atmospheric precipitation. The simulation degree of the experimental environment is low, and it is impossible to effectively reproduce the typical frontal precipitation process in nature, which restricts the development of experiments related to the real precipitation mechanism.

[0004] Therefore, there is an urgent need to propose a cloud chamber with adjustable angles for cold and warm fronts to generate rain and produce clouds, in order to solve the problem that existing technologies cannot simulate cloud formation and rain production under real conditions. Summary of the Invention

[0005] In view of the above facts, in order to solve the problem that the existing technology cannot simulate the cloud formation and rainmaking phenomenon under real conditions, the present invention designs a cloud chamber with adjustable cold front and warm front angles for cloud formation and rainmaking.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cloud chamber for cloud formation and rainmaking with adjustable cold and warm front angles includes a cloud chamber, an electric heater, a steam inlet, a cooling coil, and a vacuum tank.

[0008] The bottom and side walls of the cloud chamber are equipped with electric heaters, and the side and bottom walls are equipped with steam inlets, which are connected to steam injection pipes. Cooling coils are installed on the side walls of the cloud chamber, and the cooling coils are filled with refrigerant.

[0009] The top of the cloud chamber is connected to the first vacuum pump, the second vacuum pump, and the vacuum tank, respectively.

[0010] Furthermore, two electric heaters are provided at the bottom of the cloud chamber.

[0011] Furthermore, the cloud chamber has two steam inlets on the top layer of its side wall, two steam inlets on the bottom layer of its side wall, and one steam inlet on the bottom wall.

[0012] Furthermore, a first solenoid valve is provided between the first vacuum pump and the cloud chamber.

[0013] Furthermore, a second solenoid valve is provided between the second vacuum pump and the cloud chamber.

[0014] Furthermore, a third solenoid valve is provided between the vacuum tank and the cloud chamber.

[0015] Furthermore, the steam injection pipe is made of a flexible material.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention can simulate the natural phenomenon of cloud formation and rain formation by heating or cooling water vapor through equipment such as refrigerators and heaters to form saturated water vapor at different temperatures, which serve as warm and cold air masses respectively.

[0018] 2. In nature, the temperature decreases as altitude increases. Therefore, cloud chambers need to generate a temperature gradient to simulate the temperature gradient in real nature to a certain extent. This invention controls the cooling temperature by controlling the inlet temperature and flow rate of the refrigerant in the cooling pipe. That is, the inlet temperature of the refrigerant in the cooling pipe is about 10°C lower than the actual cloud chamber temperature.

[0019] 3. This invention achieves temperature rise by controlling the temperature of the electric heater, thereby realizing a temperature gradient.

[0020] 4. The steam injection pipe of the present invention can adjust the injection angle to form cold fronts and warm fronts with different intersection angles. Attached Figure Description
