Specific embodiment
Embodiments of the present invention are described below in detail, the example of embodiment is shown in the accompanying drawings, wherein identical or class
As label indicate same or similar element or element with the same or similar functions from beginning to end.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Referring to Fig.1, it is a kind of embodiment of the invention, provides a kind of respirator cooling device, including shell 1, it should
Shell 1 has two openings, and two openings are symmetricly set on the top and bottom of shell 1, are configured with three heat transfer pieces 2 in shell 1；
It is spaced between adjacent heat transfer piece 2 and between heat transfer piece 2 and the inner wall of shell 1, to make airflow channel, on each heat transfer piece 2
Several conducting elements 3 are respectively equipped with, are provided with hydrating structure on conducting element 3.
This respirator cooling device, there are gas between adjacent heat transfer piece 2 and between heat transfer piece 2 and the inner wall of shell 1
Circulation road, heat transfer piece 2 are equipped with several conducting elements 3 for having hydrating structure to guide the flow direction of gas, avoid gas random
It alters；And gas will hit conducting element 3 when passing through from airflow channel, to increase its residence time in the device, when making air-breathing
Heat transfer piece 2 has time enough to absorb the temperature of high-temperature gas, effectively improves cooling effect.
Since inside chemical oxygen respirator, carbon dioxide can all be reacted with water with superoxides, in characteristics of contaminated respiratory droplets gas
Moisture is utilized in initial reaction stage by chemical reaction, as the case where excess moisture will occur in the extension of time, makes superoxides
It dissolves, crumble, volume expansion, causing superoxides fixed bed porosity to become smaller, respiratory resistance is caused to increase.When the device application
When chemical oxygen respirator, gas increases the residence time in airflow channel because hitting conducting element 3, when so that exhaling,
The case where hydrating structure has time enough to absorb the moisture in gas, slows down excess moisture, effectively reduces the same of respiratory resistance
When increase device storage heat intensity.
According to Fig. 3, Fig. 4, conducting element 3 is distributed on two apparent surfaces of heat transfer piece 2, is located at same airflow channel
The case where position of the conducting element 3 of two sides mutually staggers, and can avoid airflow channel blocking caused by overlapping of conducting element 3 etc. is sent out
It is raw, so that gas is extended under the guiding of conducting element 3 and smoothly shuttles while the residence time on heat transfer piece 2.Respectively lead
Stream part 3 is plane tabular structure, it is possible to increase the contact area of conducting element 3 and gas effectively plays the effect for stopping air-flow, also makes
When must exhale, hydrating structure has time enough to absorb the moisture in gas, the problem of to alleviate excess moisture, reduces breathing resistance
Power.Angle is respectively formed between each conducting element 3 and heat transfer piece 2, the size of each angle is 30 degree.
In the embodiment, as shown in Fig. 2, each heat transfer piece 2 is in tabular, and heat transfer piece 2 and conducting element 3 are integrally formed.
The making material of heat transfer piece 2 uses aluminium alloy, and each conducting element 3 is directly stamped and formed out on heat transfer piece 2.Two tables of each heat transfer piece 2
Expiration guide portion, air-breathing guide portion are divided on face, expiration guide portion and air-breathing guide portion respectively account for the side on surface, are located at and exhale
The conducting element 3 and the angle of heat transfer piece 2 of guide portion side are opening down, conducting element 3 and heat transfer positioned at air-breathing guide portion side
The angle of part 2 is opening up.
Referring to Fig.1, the hydrating structure in the present embodiment is the water suction being covered on the surface towards entrance of each conducting element 3
Layer 31.After water absorption layer 31 absorbs water, the intensity for the storage heat for making entire cooling device is increased, thus absorbable more heat
Amount.In order to reach better soaking effect, the material of water absorption layer 31 uses sponge, and sponge passes through glue and 3 phase adhesion of conducting element.
Water-absorbent material mostly uses the material of silica gel or similar silica gel currently on the market, but silica gel is in use for some time, surface
It falls off after will become powder, so that eupnea is influenced, meanwhile, the water absorbing capacity of sponge is relatively strong compared with silica gel, so using
Material of the sponge as water absorption layer 31.
In order to reach better endothermic effect, with reference to Fig. 5, the surface of 2 two sides of heat transfer piece is equipped with heat absorbing coating 5, applies
The material of the heat absorbing coating 5 with a thickness of 10~12 μm, in the present embodiment is covered using polytetrafluoroethylene (PTFE).Due to the thermal coefficient of metal
Be it is constant, in order to enhance its capacity of heat transmission, can metal surface spray heat absorbing coating 5, increase heat absorption capacity, to realize suction
The quickening of the thermal efficiency.
It cools to make air-flow preferably pass through cooling device realization, such as Fig. 1, each heat transfer piece 2 is parallel to two and opens
The center line connecting direction setting of mouth.
In the present embodiment, the top opening of shell 1 is arranged to fence type, and the opening positioned at 1 bottom of shell slides dress
Equipped with fixed door 4, the slideway slid into for fixed door 4 is arranged in the two sides of opening, opens up several perforation supplied gas streams in fixed door 4
Logical, each perforation is strip perforation, and parallel side-by-side is distributed in fixed door 4.Such setting can reduce gas disengaging cooling
Obtained obstruction when device, it is ensured that the smooth degree of gas circulation.
As shown in figure 3, the specified airflow direction that the cryogenic gas breathed out out of human body is oriented to by conducting element 3 is logical when exhaling
Airflow channel is crossed, cryogenic gas impinges upon the surface of conducting element 3 during flowing, and the hydrating structure on conducting element 3 absorbs gas
Moisture in body, while cryogenic gas shuttles between heat transfer piece 2, takes away the temperature on heat transfer piece 2.
As shown in figure 4, when air-breathing during which extraneous high-temperature gas is impinged upon by the airflow channel that is directed through of conducting element 3
On heat transfer piece 2, the heat transfer piece 2 for being coated with heat absorbing coating absorbs the heat of high-temperature gas, makes its temperature reduction, to reach cooling
The purpose of gas.
A kind of respirator, including respirator cooling device as above.It uses the modes of Physical temperature-lowering, are exhaled using this
Haustorium, when air-breathing, the heat of external high temperature gas is transferred on cooling device, and cooling device heating reaches reduction gas temperature
Effect；When expiration, the cryogenic gas of characteristics of contaminated respiratory droplets is absorbed its heat when apparatus for supercooling, and reaching reduces cooling device temperature
Effect；One breath cycle of human body, cooling device is interior to complete a heat exchange circulation.
Certainly, design of the invention creation is not limited to above embodiment, and those skilled in the art are not
Equivalent deformation or replacement can be also made under the premise of violating spirit of that invention, these equivalent variation or replacement are all contained in this Shen
It please be in claim limited range.
