Description

[0001] The present invention relates to a dehumidifying module having waterproof and breathable properties,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidification module, and more particularly, to a dehumidification module having a waterproof and breathable structure to which a Gortex membrane and a storage capable of filling a dehumidifier are applied.

In general, precision optical equipment is widely used for military purposes, such as for reconnaissance or target acquisition.

Optical equipment mounted on reconnaissance equipment, tanks, and armored vehicles, and optical equipment for target acquisition applied to guns and guns.

Optical equipment used for military use should be operated outdoors even in case of rain, and optical equipment capable of operating in submersible environment is needed if it is mounted on an armored car capable of Doha.

The precision optical equipments such as the above are generally constructed as a complete hermetic structure for waterproofing and dehumidifying, and a periodic nitrogen injection method is applied.

In the case of optical equipment in which the structure strength due to a pressure difference is a problem, a ventilation hole and a dehumidifying filter module were applied.

However, in the case of the completely closed type, there is a disadvantage that the weight of the equipment becomes heavy because the structure itself must maintain high strength in order to prevent deformation of the structure due to temperature and altitude difference. Therefore, it could be applied to large-sized equipment such as tanks, airplane armored vehicles, etc., but it could not be applied to equipment that emphasized portability or mobility such as guns, artillery, and telescopes.

In addition, when a complete enclosure system is applied to a high magnification optical apparatus, there is a problem that an error of visible distance due to a change in internal pressure due to a temperature and an altitude difference occurs, so that it is difficult to apply to an optical apparatus requiring accuracy.

In addition, it is difficult to keep the internal temperature constant since it is difficult to discharge heat generated from the inside, and it is difficult to visually confirm the internal nitrogen exchange time, There is a disadvantage in that the convenience of the operation is greatly reduced because the recharging is performed using the communication charging bench.

Also, there is a problem in that a safety accident is likely to occur during the use of the pressure control valve when injecting nitrogen.

On the other hand, in the case of a system using a ventilation hole and a dehumidification filter, oil, salt, dust and foreign matter due to pressure difference or similar force inside and outside the equipment are infiltrated and there is a risk of inundation, which can be applied to armored vehicles and tanks And the performance of the equipment was greatly deteriorated according to the humidity.

Further, since the structure is complicated in structure, the housing is disassembled when the dehumidifying filter module is mounted on the optical equipment, which is inconvenient.

Therefore, there is a need for a dehumidifying module that is waterproof and breathable and can be made compact and lightweight.

As shown in FIG. 3, air flowing between the module mount 110 and the protective cap 120 and passing through the gore-tex membrane 130 flows into the first dehumidifying space.

The retainer 140 is located at a portion where the primary dehumidification space of the module mount 110 communicates with the internal space of the housing 300 and a number of holes smaller than the dehumidifying agent particles are formed, Thereby preventing the desiccant filled in the inside from escaping. In addition, the external air passing through the primary dehumidification space can be introduced into the housing 300.

In addition, the heated air inside the housing 300 may be discharged to the outside through the Gore-Tex membrane 130.

Therefore, it is possible to solve the problem that the conventional airtight sealing system is lightweight and difficult to dissipate heat due to the flow of air inside and outside the housing 300, and at the same time, the waterproof and air permeable property of the Gore- There is an effect that the sudden pressure difference inside and the overheating can be solved.

In addition, due to the flow resistance effect of air passing through the inside and outside of the equipment, air can pass through the gore-tex membrane 130, and thus the stability and performance of the equipment can be maintained by preventing a rapid change in internal pressure due to temperature difference and external altitude difference. have.

Meanwhile, the protection cap 120 may be formed with a hole to communicate with the primary dehumidification space of the module mount 110.

Accordingly, the state of the dehumidifying agent can be visually confirmed through the transparent window 150 regardless of the power state of the equipment, and it is possible to easily determine an appropriate replacement period of the dehumidifying agent.

At this time, it is preferable that the dehumidifying agent to be filled in the primary dehumidifying space is applied with a dehumidifying material which can change its color or state according to the moisture content and can observe the change visually.

An O-ring 160 that seals between the housing 300 and the module mount 110 when the module 300 is mounted on the module 300 may be coupled to the module mount 110. At this time, it is preferable that a material such as rubber or silicone having a slight elasticity is applied to the O-ring 160 so as to exhibit a more reliable sealing effect.

The module mount 110 may include an inlet 112, a boss 114, and a flange 116.

The inflow portion 112 protrudes in a direction toward the outside of the housing 300 and is coupled to the outside of the protection cap 120. The inflow portion 112a includes at least one ventilation hole 112a And the first dehumidifying space is formed on the inner side.

The boss 114 is coupled to the housing 300 and protrudes in a direction toward the inside of the housing 300 so that the air introduced from the outside flows into the inside of the housing 300, So as to be communicated with each other. At this time, the boss 114 may be formed with threads or the like on the outer circumferential surface for coupling with the housing 300.

Referring to FIG. 4, a process of dehumidifying air by a dehumidifying module having waterproof and breathable characteristics will be described.

External air is introduced into the gap between the protection cap 120 and the module mount 110. The introduced external air passes through the Gore-Tex membrane 130, so that foreign substances and liquid are filtered, and only water vapor and air pass therethrough . The air filtered by the gore-tex membrane 130, for example, foreign matter, liquid, or the like is further introduced into the vent hole 112a, and dehumidified by the dehumidifying agent filled in the primary dehumidifying space in the module mount 110. The dehumidified air flows into the housing 300 through the retainer 140.

When the present invention further includes the desiccant storage 200, the dehumidified air having passed through the retainer 140 is dehumidified again by the desiccant filled in the desiccant storage 200. The second dehumidified air flows into the housing (300).

Therefore, when the air inside the housing is heated due to the heat generated by the operation of the equipment, the internal air is discharged to the outside through the Gore-Tex membrane 130 by the expansion pressure, To maintain the stability and performance of the equipment for longer.

The waterproof and breathable dehumidification module of the present invention having the above-described structure can be applied to optical and electronic equipment that is required to maintain humidity and internal pressure in the equipment and used in a flooded environment.

In particular, tanks and airplanes used for military purposes are used outdoors even in the case of rain, and in the case of armored vehicles capable of water-driving with a dozing capability, they operate in a submerged environment, And electronic equipment.

In addition, since the present invention is lightweight and compact, and has air permeability, it is relatively small in size such as optical equipment for target acquisition applied to cannons, reconnaissance telescopes, gun guns, etc., It can also be applied to applied optical equipment.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
