Abstract
A small-space fast cooling device comprises a liquid nitrogen steel cylinder and a liquid oxygen steel cylinder, wherein a liquid nitrogen electric control pressure reducing valve and a liquid oxygen electric control pressure reducing valve are arranged on an opening of the liquid nitrogen steel cylinder and on an opening of the liquid oxygen steel cylinder respectively, one end of a nitrogen pipe and one end of an oxygen pipe are connected to the liquid nitrogen electric control pressure reducing valve and the liquid oxygen electric control pressure reducing valve respectively, the other end of the nitrogen pipe and the other end of the oxygen pipe are converged to a gas pipe, and a gas outlet is formed in the end of the gas pipe; the liquid nitrogen electric control pressure reducing valve and the liquid oxygen electric control pressure reducing valve are connected in a control circuit in parallel, a power supply and a circuit switch are arranged in the circuit, the power supply can be integrated with a power supply of the space where the cooling device is located, and the gas outlet can be integrated with an air outlet of an air-conditioner in the space where the cooling device is located. According to the small-space fast cooling device, cooling time is short, the cooling effect can be achieved within a half minute, and the defects that an existing air conditioner used by an automobile or used in other small spaces is long in cooling time and can increase fuel oil consumption and exhaust emission are overcome; a comfortable environment can be created for people as soon as possible.
Description
Technical field
The utility model relates to a kind of little space fast cooling device, can realize the fast cooling in automotive interior or other little spaces.
Background technology
In summer, be parked in car outdoor, and vehicle interior temperature is generally all very high, sometimes even can reach more than 50 ℃.Higher temperature feels sick the personnel that take or drive, although car is in-built air-conditioning is arranged, and the temperature fall time of air-conditioning is relatively long, and needs to increase fuel consume and toxic emission, affects the performance of automotive performance.
Summary of the invention
The purpose of this utility model provides a kind of little space fast cooling device, can the fast reducing vehicle interior temperature, and the utility model also can be used for the fast cooling in other little spaces simultaneously.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of little space fast cooling device, comprise liquid nitrogen steel cylinder and liquid oxygen steel cylinder, the bottleneck of described liquid nitrogen steel cylinder and liquid oxygen steel cylinder is respectively equipped with liquid nitrogen electronic control pressure reducing valve and liquid oxygen electronic control pressure reducing valve, one end of nitrogen tube and oxygen hose is connected respectively to liquid nitrogen electronic control pressure reducing valve and liquid oxygen electronic control pressure reducing valve, the other end converges to appendix, and the termination of appendix is provided with gas outlet; Described liquid nitrogen electronic control pressure reducing valve and liquid oxygen electronic control pressure reducing valve are connected in parallel in control circuit, and are provided with power supply and contactor in circuit, and power supply can be integrated with the Power Management Design in the utility model space of living in.Described gas outlet can be made as one with the air-conditioner air outlet in the utility model space of living in.
Liquid nitrogen electronic control pressure reducing valve 3 is controlled at 0.02m with the throughput of liquid oxygen electronic control pressure reducing valve 4
3/ s～0.20m
3between/s.
Because the boiling point of liquid nitrogen is low, can absorb amount of heat during liquid nitrogen gasification, the utility model utilizes this principle, by the temperature fast-descending that makes surrounding environment of liquid nitrogen, reaches the effect of refrigeration.
Temperature fall time of the present utility model is short, half a minute is with the interior effect that can reach cooling, and lowered the temperature with air-conditioning, need at the soonest capablely in 5min to reach the cooling requirement, overcome existing automobile or other little space use air-conditioning temperature-reducing time long, and can increase the defect of fuel consume and toxic emission; Build as early as possible comfortable environment can to people.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit diagram of the present utility model.
the specific embodiment
As shown in Figure 1, 2, the utility model comprises liquid nitrogen steel cylinder 1 and liquid oxygen steel cylinder 2, the bottleneck of described liquid nitrogen steel cylinder 1 and liquid oxygen steel cylinder 2 is respectively equipped with liquid nitrogen electronic control pressure reducing valve 3 and liquid oxygen electronic control pressure reducing valve 4, one end of nitrogen tube 5 and oxygen hose 6 is connected respectively to liquid nitrogen electronic control pressure reducing valve 3 and liquid oxygen electronic control pressure reducing valve 4, the other end converges to appendix 7, and the termination of appendix 7 is provided with gas outlet; Described liquid nitrogen electronic control pressure reducing valve 3 and liquid oxygen electronic control pressure reducing valve 4 are connected in parallel in control circuit, and are provided with power supply and contactor 8 in circuit.
Liquid nitrogen electronic control pressure reducing valve 3 is controlled at 0.02m with the throughput of liquid oxygen electronic control pressure reducing valve 4
3/ s～0.20m
3between/s.
During use, open circuit switch 8, now liquid nitrogen electronic control pressure reducing valve 3 and liquid oxygen electronic control pressure reducing valve 4 can be opened automatically, nitrogen and oxygen are discharged in beginning to space, reach the purpose that reduces temperature, after temperature is suitable, circuit disconnect switch 8, can stop discharging nitrogen and oxygen in environment.
