In the battery case system 100 having excellent heating and cooling performance of the present embodiment,

A case body 110 having a structure in which an internal space is formed and in which a battery cell can be inserted;

A carbon heating fiber 120 bonded to an inner wall of the case body 110;

An auxiliary battery 130 for applying electric power to the carbon heating fibers 120;

A fan module 160 coupled to the case body 110 and capable of injecting outside air into the case body 110;

A first temperature sensor 141 for sensing a temperature inside the case body 110;

A second temperature sensor 142 for sensing a temperature outside the case body 110;

(20) coupled to the inside of the case body (110) and pushing up the lid of the case body (110) during operation;

The temperature information of the first temperature sensor 141 and the second temperature sensor 142 may be analyzed so that the temperature inside the case body 110 may be maintained at a predetermined temperature range, And a control unit 150 that operates the fan module 160 or applies electric power to the carbon heating fibers 120.

The case body 110 has a closed structure so that the inside and outside of the case body 110 can be waterproofed. Plastic or metal materials. A battery cell can be inserted into the case body 110.

The carbon heating fibers 120 are coupled to the inside of the case body 110. The carbon heating fiber 120 is a material that generates heat even when a low power is applied. The carbon heating fibers 120 can be bonded to the partition wall or the inner wall dividing the compartment inside the case body 110. [

The auxiliary battery 130 applies electric power to the carbon heating fibers 120. Since the auxiliary battery 130 is located inside the case body 110, it can be placed in an environment of the optimum temperature range.

The first temperature sensor 141 senses the temperature inside the case body 110. The information of the first temperature sensor 141 is transmitted to the controller 150. The second temperature sensor 142 senses the temperature outside the case body 110. The control unit 150 maintains the internal temperature of the case body 110 at a predetermined temperature interval. The controller 150 selects whether to operate the carbon fiber heating fibers 120 or the fan module 160. [

For example, the control unit 150 allows the internal temperature of the case body 110 to be maintained within a predetermined temperature range (for example, between about 18 degrees Celsius and about 25 degrees Celsius). If the internal temperature of the case body 110 is 10 degrees Celsius from the temperature information of the first temperature sensor 141 and the external temperature of the case body 110 from the second temperature sensor 142 is 5 degrees Celsius, Power is supplied to the heat-generating fibers 20 to raise the temperature inside the case body 110.

On the other hand, when the internal temperature of the case body 110 is 30 degrees centigrade and the external temperature of the case body 110 is 10 degrees centigrade, the fan module 160 is operated to allow external air to flow into the case body 110 Respectively.

2 is a block diagram of a driving system using a battery case system having excellent heating and cooling performance according to an embodiment of the present invention.

The drive system 200 of the present embodiment is a system that can be applied to an apparatus that is driven by electricity such as an electric boat or an electric vehicle.

The driving system 200 of the present embodiment includes a battery case system 100 having excellent heating and cooling performance with built-in batteries; A battery management module 210 for controlling the battery; A precharge relay 220; Voltage drop device 230; A display 240, and a motor control unit 250.

The battery management module 210 is a device that manages all the batteries, such as the axial discharge temperature of the battery.

When the high voltage is applied to the motor controller, the precharge relay 220 causes component damage. Therefore, it is a device that sends a high voltage after pre-charging the voltage through a certain resistance element.

The motor control unit 250 is a device for controlling the motor.

The information displayed on the display 240 can be checked through the smartphone 260 and the motor control unit 250 and the battery case system 100 having excellent heating and cooling performance can be confirmed through the smart phone 260. [ As shown in FIG.

On the other hand, a simple actuator 20 is coupled to the inside of the case body 110. When the internal temperature of the case body 110 is not properly controlled due to a malfunction of the control unit 150, the weak actuator 20 operates and explodes to forcibly open the lid of the case body 110. At this time, the ink R contained in the flexible actuator 20 is ejected to the outside, so that it can be visually confirmed easily. In addition, it is possible to prevent the battery from being damaged by the high temperature.

FIG. 3 is a perspective view of a simplified actuator according to an embodiment of the present invention (a state in which a rod does not protrude), FIG. 4 is a perspective view of a simplified actuator according to an embodiment of the present invention, FIG. 5 is a cross-sectional view of a simplified actuator according to an embodiment of the present invention (without the rod protruding), FIG. 6 is a cross-sectional view and partial enlargement of the simplified actuator according to an embodiment of the present invention FIG. 7 is a cross-sectional view and a partially enlarged view of a simplified actuator according to an embodiment of the present invention (a state in which a rod is partially inserted by a load after explosion of a explosive).

The flexible actuator 20 of the present embodiment is inserted into the case body 110 and pushes up the lid of the case body 110 in operation. In addition, the ink R in the flexible actuator 20 is ejected.

If the fan module 160 fails or does not operate, the internal temperature of the case body 110 is overheated. At this time, the air-operated actuator 20 is operated to open the lid of the case body 110, so that external air can be introduced into the case body 110. In addition, when the chemical mechanical actuator 20 operates, the ink R in the cylinder is ejected and can be easily recognized from the outside.

The simplified actuator 20 of this embodiment immediately pushes up the rod 24 after the explosive has exploded. When the rod 24 is pushed up to the end, the gas discharge portion 25 is exposed. A part of the high-pressure gas inside the cylinder 21 is discharged to the outside through the gas discharge part 25. [ Thereafter, when the pressure inside the cylinder 21 falls, the rod 24 is partly inserted into the cylinder 21 by the spring 26, and the gas discharge portion 25 moves into the cylinder 21. Thereafter, the cylinder 21 and the rod 24 function as dampers, without any further discharge of gas, so as to maintain proper cushioning.

The mechanical actuator 20 includes a cylinder 21 having an inner hollow and an engagement protrusion 211 protruding inward from an upper portion thereof; A sealing part 22 formed inside the cylinder 21; A gunpowder part 23 coupled to a lower part of the cylinder 21 and exploding by an external electric stimulus; a cylinder part 21 which is guided by the cylinder 21 and whose outer side is in close contact with the sealing part 22, A rod 24 protruding from a stopper 241 to prevent the engaging protrusion 211 from being detached from the cylinder 21; A gas discharging portion (not shown) formed at a lower portion of the rod 24 is provided so that the rod 24 can be exposed to the outside when the rod 24 protrudes to the maximum, 25 and a spring 26 interposed between the latching protrusion 211 and the stopper 241. In addition, the cylinder 21 is filled with the ink R. The ink R may be a red color.

The inside of the cylinder 21 is empty. An engagement protrusion 211 protruding inward is formed in the upper portion of the cylinder 21. [ The latching protrusion 221 has a shape corresponding to the stopper 241 of the rod 24 to be caught. When the high-pressure explosive instantaneously explodes, the rod 24 pushes up the rod 24, and the rod 24 does not come off the cylinder 21 by the stopper 241 of the rod 24.

A sealing portion 22 is formed on the upper portion of the cylinder 21. The sealing portion 22 is in close contact with the outside of the rod 24. The sealing part 22 is made of an O-ring to block the movement of the gas inside the cylinder 21. [

The gunpowder (23) is coupled to the lower portion of the cylinder (21). When electrical stimulation is delivered to the gunpowder 23, the gunpowder of the gunpowder 23 explodes and generates a high-pressure gas. The pressure of this gas pushes up the rod 24.

The rod 24 is guided by the cylinder 21. The outer side of the rod (24) is in close contact with the sealing portion (22). A stopper 241 protrudes outward from the bottom of the rod 24. The stopper 241 of the rod 24 is caught by the engaging protrusion 211 inside the cylinder 21 and is not released from the cylinder 21 when the explosive explosion causes the rod 24 to protrude to the outside.

The gas discharge portion 25 is formed at the lower portion of the rod 24. The gas discharge portion 25 is exposed to the outside when the rod 24 protrudes from the cylinder 21 to the maximum. At this time, the gas (generated by the explosion of gunpowder) in the cylinder 21 can escape to the outside through the gas discharging part 25. [ In addition, the ink R is ejected together with the gas (see Fig. 7)

A spring 26 is interposed between the engaging protrusion 221 and the stopper 241. As shown in FIG. 6, when the gunpowder explodes and the rod 24 rises, the spring 26 is compressed. Thereafter, when the internal gas is discharged through the gas discharge portion 25, the rod 24 is lowered by the spring 26, and the discharge of the gas is stopped.

As shown in Fig. 5, the rod 24 is normally inserted into the cylinder 21, and only a portion of the upper portion thereof is exposed. Thereafter, when the explosive part 23 is exploded by an external impact, a high-pressure gas is generated, and the high-pressure gas pushes up the rod 24 as shown in FIG.

As shown in the enlarged cross-sectional view of Fig. 7, the hollow rod 24 has a hole-shaped gas discharge portion 25 formed therein. When the high-pressure rod 24 is lifted up to the end, the gas inside the cylinder 21 is discharged to the outside through the gas discharge portion 25. Therefore, the gas pressure inside the cylinder 21 drops. Depending on the size of the gas discharging portion 25, the amount of discharged gas differs.

Thereafter, the rod 24 is pushed into the cylinder 21 by the spring 26. At this time, since the gas discharge portion 25 enters the inside of the cylinder 21, there is no further leakage of gas. If a suitable amount of gas is discharged to the outside, the remaining gas maintains an appropriate pressure so that it acts as a damper when the rod 24 is pushed into the cylinder 21.

In the absence of the gas discharge portion 25, the high-pressure gas generated during the explosion of the explosive gas is present in the cylinder as it is. Even if an external impact is transmitted to the rod 24, the rod 24 is pushed into the cylinder 21 I did not go in. That is, the rod 24 becomes too hard to function as a damper. In the absence of the spring 26, too much gas may escape to the gas discharge portion 25 and the damper may not be able to function.

However, the flexible actuator 20 of this embodiment pushes up the rod 24 by using the high-pressure gas generated when the explosive gas explodes, pushing the hood 30 down, lowering the spring 26, 21 so that the rod 24 can have an appropriate buffering force to absorb an external impact.

A heat pipe 170 is coupled to the case body. The heat pipe is composed of a hollow pipe sealed in a depressurized state of the working fluid. The heat generated from the heat source is absorbed by one end of the heat pipe, and the working fluid absorbs heat to be dissipated and transfers heat to the other end. This process is called "Latent Heat Transfer" and is used in low temperature osmosis (Water Sprinkling), which is often used to eliminate heat island phenomena. For this reason, heatpipes are three to five times higher in heat transfer than diamonds, and not only those who do not need external power supply, but also have a very fast response to heat.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Modifications and additions by those skilled in the art to an equivalent range based on the embodiments will also fall within the scope of the present invention.
