In modern society, most of the tasks in defense, finance, and control are processed through computerization, electronics, communication, computer equipment, etc., and these systems are destroyed and damaged by external artificial or natural causes. If the damage is serious, it will cause serious consequences beyond imagination. Therefore, various attempts are being actively made to strengthen security and invest in security facilities to prevent such damage.

Particularly, electromagnetic pulse (hereinafter referred to as EMP) refers to electromagnetic energy that is generated naturally by lightning, or artificially generated by an electronic bomb. EMP with such an electronic bomb causes rapid generation of high microwave energy And damage the defense, financial, and industrial infrastructure by damaging and destroying defense computer information system, administrative computer system, financial information system and so on by disabling computerization, electronics, communication and computer equipment.

However, the conventional EMP protection rack implements the purpose of shielding the EMP in various ways for shielding, but it is difficult to prevent the EMP protection due to the heat generated when the equipment installed in the rack, especially the server, As the temperature rises rapidly inside the rack, the stable operation of the computer equipment installed in the rack can not be guaranteed.

That is, when the internal temperature rises due to the internal heat, the server and the computer equipment installed in the EMP protection rack are subjected to a fatal problem such as shutdown or damage.

In other words, the conventional EMP protection rack is cooled by the air conditioner or the air conditioner in the server room, and the heat discharged from the equipment installed inside the rack is forcibly discharged to the cooling fan through the honeycomb. In case of failure of the air conditioner or the air conditioner, The equipment of the rack installed inside is overheated and burnout occurs.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the present invention is configured to cool one or more thermoelectric elements 100 inside a housing 10 of a server rack to generate heat from electromagnetic waves.

First, the EMP is caused by a nuclear explosion or e-bomb that causes malfunctions and malfunctions of electrical and electronic equipment, resulting in paralysis of the national / defense command and communication network and social network. It is a protective measure against key facilities and equipment.

In other words, it is operated for the protection of electric and electronic equipments in all fields of the EMP situation, not only in national defense and defense fields, but also in finance and traffic, and also in social environment. Also, in case of EMP due to nuclear explosion and terror (e-bomb) To operate or maintain the network.

In consideration of the cost effectiveness caused by manufacturing racks against the cost of constructing commercial facilities that can be operated normally under the EMP situation and the cost of constructing the facilities for EMP protection and considering the mobility according to the specific field of defense, It is imperative that measures are taken to protect them.

In particular, since network equipment is distributed and deployed, it is necessary to develop a protection measure for each rack because it is too wide to protect the facility itself.

This is because it is difficult to guarantee the safety of existing foreign products as the EMP threat continues to evolve, and it is necessary to develop and apply the corresponding technology.

In other words, the expansion of the wideband frequency (from 1 GHz to 18 GHz), the EMP protection technology of the antenna lead-in portion, and the weight reduction technology of the housing are desperately required.

Accordingly, the EMP rack of the present invention is based on a commercially operated rack, and is classified into a server, a communication equipment, and the like depending on the use. The protective enclosure aims at development of a lightweight and easy-to- It is designed for the complete shielding of inner and outer parts and the performance of various power source, signal line and antenna line to protect 100% of internal equipments under EMP condition including excellent shielding effect, weight and heat dissipation effect by MIL-STD-188-125 measurement standard And IEEE-STD-299 measurement standards to meet the requirements.

As shown in the following Table 1, the current requirement is 1 GHz, 80 dB or more. However, the present invention has developed an ultra-wideband rack and a protection enclosure that covers the threat of high output electromagnetic waves due to denuclearization, As shown in FIG.

SE test method of MIL-STD-188-125

The basic concept of thermoelectric technology is the Peltier effect, which was first discovered in the early 19th century. It refers to the phenomenon of endothermic or exothermic phenomena occurring at junctions of two different conductors depending on the direction of current when current flows through two different conductors.

That is, the thermoelectric semiconductor is a material selected to produce the Peltier effect, pumping heat, which not only exerts higher performance than other materials, but also has an advantage of controlling the characteristics of the charge carrier inside the conductor.

Using the properties of these materials, the thermoelectric module can be made by joining the two ends of one semiconductor element with an electrically conductive material (copper electrode).

In the configuration shown above, the components necessary for the Peltier effect are the copper lines that connect to the power supply, and the heat is transferred through the circuit in the direction that the charge carrier moves (ie, the heat transfer material is the charge carrier).

In other words, the N-type material is generally manufactured in the form of pellets, so that the electrons having negative electric charge become the charge carriers to cause the Peltier effect in the N-type material.

When the DC power source is connected as shown in the figure, the electrons protrude from the cathode and are attracted to the anode. By this polarity, electrons flow clockwise as shown in the figure.

Thus, electrons flowing below and above the N-type semiconductor absorb heat at the lower contact and actively move to the upper contact to release heat.

That is, heat is effectively pumped by the charge carrier in the semiconductor device.

The thermoelectric module also incorporates a P-type semiconductor device, and the P-type device is manufactured such that a positive charge called a hole serves as a charge carrier inside.

The holes increase the electric conductivity of the P-type crystal structure because electrons can flow more freely in the material when voltage is applied.

Positive charge carriers protrude from the anode of the DC power source and are drawn to the cathode, resulting in the flow of holes in the direction opposite to the electrons.

This is due to the inherent charge carriers that can transfer heat within the conductor. Using a P-type material as the material that conducts heat through the conductor results in heat being absorbed at the cathode of the power source and emitted at the cathode.

The thermoelectric element 100 is preferably a Peltier element formed at the upper and lower ends of the inside of the housing.

Since the present invention develops EMP protection racks and mobile enclosures in Korea, it minimizes the waste of foreign currency due to accumulation of technology and imports of foreign products, and contributes to the development and production of domestic cooperating companies, As shown in FIG.

Further, the present invention is introduced into the C4I system of the military so as to improve the operational performance and to carry out missions without difficulty in any battlefield.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
