Abstract
The utility model discloses a respirator cooling device which comprises a cooling casing, wherein two recesses are formed in one surface of the cooling casing, and two corresponding bulged cylindrical cooling medium storage cavities are formed in the other surface of the cooling case; guide plates are arranged on two sides of the bulged cylindrical cooling medium storage cavities formed in the other surface of the cooling casing; a diversion trench is formed between each of the cooling medium storage cavities and each of the guide plates; an air inlet is formed in one end of each of the diversion trenches, and an air outlet is formed in other end of the diversion trench. When the respirator cooling device works, the air enters from the air inlets and flows along the diversion trenches, and as the cooling medium storage cavities are filled with cooling media, the cooling medium plays a role in reducing the air temperature when the air flows in the diversion trenches, the cooling effect is excellent, and the airflow is uniform.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to the cooling device using on a kind of respirator.
Background technology
Cabin formula positive pressure oxygen respirator is a closed circuit circulatory system, and internal pressure is greater than external atmospheric pressure, just can avoid poison gas entering surface cover in environment, harmful to human.When using, the calcium hydroxide chemically reactive of the carbon dioxide of characteristics of contaminated respiratory droplets and absorbent tank is emitted heat, makes suction temperature constantly increase, and cooling device feels comfortable in order to reduce when suction temperature makes human body air-breathing exactly.Current cabin formula positive pressure oxygen respirator is equipped with a cooling tank in breathing cabin, and cooling core is installed in tank, wants first upper casing to be removed, then cooling core is put into cooling tank before wearing.Because the design of cooling device is all single cooling, and does not design independent cooling airway and cause cooling effect poor, the shortcomings such as complicated operation.
Utility model content
For above shortcomings part in prior art, the utility model provides a kind of utilization rate of cooling agent high, the gas flow temperature good cooling effect flowing through, air-flow even breathing device cooling device.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Respirator cooling device, comprise cooling housing, the one side of described cooling housing is provided with the cooling medium storage chamber of two indents, the corresponding cylindrical structural protruding of another side, both sides at the cooling medium storage chamber of two protrusions of another side of cooling housing arrange respectively deflector, between described cooling medium storage chamber and deflector, form guiding gutter, one end of described guiding gutter is air inlet, and the other end is gas outlet.
As a kind of preferred version of the present utility model, on the edge of described deflector, sealing strip is set, described deflector is sealed and matched by the hatchcover on sealing strip and respirator.
As another kind of preferred version of the present utility model, on the opening end of described cooling medium storage chamber, be combined with seal cover.
The beneficial effects of the utility model are: when cooling device is worked, gas enters from air inlet, along guiding gutter, flow, because cooling medium storage chamber has cooling medium, gas flow is the cooling medium reduction gas temperature that plays a role in guiding gutter time, good cooling effect, and air-flow is even.
Accompanying drawing explanation
Fig. 1 is the structural representation of respirator cooling device one side;
Fig. 2 is the structural representation of respirator cooling device another side.
In accompanying drawing: 1-cooling housing; 2-cooling medium storage chamber; 3-deflector; 4-guiding gutter; 5-air inlet; 6-gas outlet; 7-sealing strip.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, respirator cooling device, comprises cooling housing 1.The one side of cooling housing 1 is provided with the cooling medium storage chamber 2 of two indents, the corresponding cylindrical structural protruding of another side, both sides at the cooling medium storage chamber 2 of two protrusions of another side of cooling housing 1 arrange respectively deflector 3, between cooling medium storage chamber 2 and deflector 3, form guiding gutter 4.One end of guiding gutter 4 is air inlet 5, and the other end is gas outlet 6.
On the opening end of cooling medium storage chamber 2, be combined with seal cover, by sealing, cover and can, to the cooling medium in cooling medium storage chamber according to need to the changing at any time of cooling effect, improve to a greater extent the convenient, fast of assembling.
While using this respirator cooling device, first cooling housing 1 is arranged on hatchcover, the one side of the deflector 3 of cooling housing 1 is sealed and matched by sealing strip 7 and hatchcover; Then hatchcover is arranged on the body of cabin.When cooling device is worked, gas enters guiding gutter 4 from air inlet 5, along guiding gutter 4, flows, and because cooling medium storage chamber 2 has cooling medium, gas flow is the cooling medium reduction gas temperature that plays a role in guiding gutter 4 time, good cooling effect, and air-flow is even.
This cooling device must guarantee to make through air-flow obtain enough coolingly, suction temperature when human body is air-breathing is no more than 35 ℃, it is comfortable that user of service just can feel.How the sealing strip of cooling device is guaranteeing sealing effectiveness in situation for a long time, so the material of sealing strip is also had to certain requirement, the sealing strip 7 in the present embodiment is selected the fluorubber of heatproof.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
