Description

에너지 저장장치의 배터리 냉각장치{Battery cooling system}Battery cooling system for energy storage devices

본 고안은 에너지 저장장치의 배터리 냉각장치에 관한 것으로서, 상세하게는 복수의 배터리에서 발생하는 열을 수냉식 대류 현상에 의해 방열하기 위한 기술에 관한 것이다.The present invention relates to a battery cooling device of an energy storage device, and more particularly, to a technology for dissipating heat generated by a plurality of batteries by a water-cooled convection phenomenon.

일반적으로 ESS(Energy Storage System)는 발전소에서 과잉 생산된 전력을 저장해 두었다가 일시적으로 전력이 부족할 때 송전해주는 저장장치를 말하며, 최근 들어서는 대규모 ESS 장치를 소형으로 구성하여 빌딩, 공장, 가정 등의 일반 수용가에서 정전 대비용 또는 피크 전력 감축용으로 사용하는 경우가 늘고 있다.In general, ESS (Energy Storage System) refers to a storage device that stores excess power generated by a power plant and transmits it temporarily when power is insufficient. In recent years, large-scale ESS devices have been constructed in small sizes to accommodate general customers such as buildings, factories, and homes. In many cases, it is used for blackout preparation or peak power reduction.

최근에는 전력 수급 불균형 등으로 인해 신재생에너지에 대한 관심이 급격하게 증가하면서, ESS를 통해 신재생에너지를 활용해 생산된 전기를 저장하고 필요한 시간대에 활용하도록 하는 기술에 대한 개발이 지속적으로 이루어지고 있다.Recently, as interest in new and renewable energy has rapidly increased due to the imbalance in power supply and demand, the development of technologies that utilize the new and renewable energy through ESS to store the generated electricity and utilize it at the required time has been continuously developed. have.

특히, 최근 들어 신축되는 공공건물에 대한 ESS의 설치가 의무화되고, 민간건물 등에도 에너지 절감 차원에서 ESS의 설치가 증가함에 따라 ESS 시장은 그 성장을 계속하고 있다.In particular, the ESS market continues to grow in recent years as the installation of ESS is mandatory in public buildings that are newly built, and the installation of ESS in energy savings is also increasing in private buildings.

건물 등에 ESS를 설치하는 경우에는 아래 특허문헌과 같은 ESS의 배터리 랙에 에너지를 저장하는 배터리, 배터리를 관리하는 BMS, 전력을 변환하는 PCS 등을 수용하도록 하고, 이러한 배터리 랙을 지하실 등의 일정 공간에 수용하여 운용토록 하고 있다.When installing an ESS in a building, etc., the battery rack for storing energy in the battery rack of the ESS as shown in the patent document below, BMS managing the battery, PCS converting power, and the like are accommodated. It is accepted for operation.

이때, 외부 온도가 높은 여름철에는 ESS 시스템의 배터리 등에서 발생하는 많은 열에 의해 ESS시스템의 온도가 과도하게 상승하게 되고, 이에 따라 화재 발생의 위험이 높으며 ESS시스템의 오류를 발생시키게 되고, 외부 온도가 낮은 겨울철에는 너무 낮은 온도로 인해 ESS시스템이 정상적으로 작동하지 않는 문제가 있다.At this time, in the summer when the external temperature is high, the temperature of the ESS system is excessively increased due to a lot of heat generated from the battery of the ESS system, and thus the risk of fire is high and an error of the ESS system is generated, and the external temperature is low. In winter, there is a problem that the ESS system does not operate normally due to too low a temperature.

그러나 현재에는 ESS시스템이 수용된 공간 전체에 대한 냉난방만이 실시되고 있어, 배터리 랙에 수용된 배터리 각각에 대한 냉각과 보온이 제대로 이루어지지 못하여 효율적이고 안정적인 ESS시스템의 운영이 어려운 실정이다.However, at present, only the heating and cooling of the entire space in which the ESS system is accommodated is performed, so it is difficult to operate an efficient and stable ESS system because cooling and heat retention for each battery accommodated in the battery rack are not properly performed.

또한, ESS 시스템은 많은 열의 발생으로 화재 발생의 위험이 높으나 이에 대한 소화 설비가 제대로 갖추어져 있지 않아 화재가 발생할 경우 막대한 재산적 피해 및 대형 화재가 발생할 위험이 매우 높은 상황이다.In addition, the ESS system has a high risk of fire due to the generation of a large amount of heat, but the fire extinguishing facility is not properly installed, and thus, in the event of a fire, there is a very high risk of massive property damage and large fire.

그리고, 다수개의 배터리팩이 사용되고, 배터리팩의 충방전 과정에서 발생되는 열에 의한 배터리팩의 손상 등을 방지하기 위하여 에너지 저장 시스템의 냉각을 위한 기술이 제안되고 있다.In addition, a plurality of battery packs are used, and a technique for cooling the energy storage system has been proposed to prevent damage to the battery pack due to heat generated during charging and discharging of the battery pack.

However, in the case of such a conventional method, the production cost is high due to the complicated structure of the cooling fan.

It is a configuration that is wired.

다음은 본 고안에 해당하는 구성을 살펴본다.The following looks at the configuration corresponding to the present design.

상기 복수의 배터리(3) 하단에 토출구(10)와 환수구(11)가 형성관 수로관(12)을 상기 배터리(3)에 밀착하되 상기 수로관(12)을 일측으로 경사지게 위치하여 상기 토출구(10)가 상기 환수구(11)와 비교할 경우 위에 있도록 하며At the bottom of the plurality of batteries (3), the discharge port (10) and the return port (11) are formed to close the water pipe (12) to the battery (3), but the water pipe (12) is inclined to one side so that the discharge port (10) ) When compared with the water outlet 11 above

상기 토출구(10)에 제2수로관(20) 일측이 연결되고One side of the second water pipe 20 is connected to the discharge port 10,

상기 제2수로관(20) 타측은 상측으로 향한 상태에서 환수관(30) 일측(31)과 연결되며The other side of the second waterway pipe 20 is connected to one side 31 of the water return pipe 30 in a state facing upward.

상기 환수관(30) 타측(32)은 상기 환수구(11)와 연결되고The other side 32 of the water pipe 30 is connected to the water outlet 11

상기 환수관(30) 내지는 상기 제2수로관(20) 상측에 외부와 관통되는 연결배관(40)을 연결한 상태에서In the state that the connection pipe 40 penetrated with the outside is connected to the upper side of the return pipe 30 or the second water pipe 20

상기 복수의 배터리(3)에서 발생되는 온열에 의해 수로관(12) 내부 액체가 온도가 상승하면 액체팽창(대류현상)하여 수로관(12)의 경사진 수로관(12)의 토출구(10)와 제2수로관(20) 상측(21)을 지나 연결배관(40)까지 이동하고 상기 연결배관(40)부터는 환수관(30)으로 흘러가 이 흘러간 온수는 환수관(30)을 지나 상기 환수구(11)로 흘러 수로관(12)으로 환수되는 구성이다.When the temperature of the liquid inside the water pipe 12 increases due to the heat generated from the plurality of batteries 3, the liquid expands (convection phenomenon) to discharge the outlet 10 and the second of the inclined water pipe 12 of the water pipe 12 After passing through the upper side 21 of the water pipe 20, it moves to the connecting pipe 40, and the flowing hot water flows from the connecting pipe 40 to the return pipe 30 and passes through the return pipe 30 to the return pipe 11 It is a configuration that flows and returns to the water pipe 12.

상기 구성의 실시예를 살펴보면 다음과 같다.Looking at the embodiment of the configuration is as follows.

복수의 배터리(3)는 외부 온도가 높은 여름철에는 ESS 시스템의 배터리(3) 등에서 발생하는 많은 열에 의해 ESS시스템의 온도가 과도하게 상승하게 된다.In the summer when the external temperature is high in the plurality of batteries 3, the temperature of the ESS system is excessively increased by a lot of heat generated from the battery 3 of the ESS system.

이와 같은 배터리(3)의 온도가 상승하면 배터리(3)와 밀착된 수로관(12) 내부의 액체와 열교환되어 상기 액체가 가온된다.When the temperature of the battery 3 rises, the liquid is heated by heat exchange with the liquid inside the water pipe 12 in close contact with the battery 3.

이처럼 열교환으로 수로관(12) 내부 액체 온도가 상승하면 상기 수로관(12)의 경사면을 따라 토출구(10)와 제2수로관(20)을 지나 연결배관(40)으로 이동 한 다음 자중에 의해 하강하여 환수관(30)으로 흘러 이동한다. As such, when the temperature of the liquid inside the water pipe 12 increases due to heat exchange, it moves to the connecting pipe 40 through the discharge port 10 and the second water pipe 20 along the inclined surface of the water pipe 12, and then descends by its own weight to return water. It flows to the tube 30 and moves.

이처럼 액체가 환수관(30)으로 흘러 환수구(11)를 지나 수로관(12)으로 환수된다.As such, the liquid flows into the return pipe 30 and passes through the return pipe 11 to be returned to the water pipe 12.

이와 같은 작용이 반복적으로 이루어져 액체가 순환하는 것이다.This action is repeated and the liquid circulates.

이 순환과정에 환수관(30)에서 대기공기와 열교환되어 가온된 액체가 방열되는 것이다.In this circulation process, the warmed liquid is dissipated by heat exchange with atmospheric air in the return pipe (30).

상기 온수자연순환 원리는 특허문헌 등록번호 10-1761561호의 배경기술에 상세하게 수록되어 있다 참고바란다.The principle of hot water natural circulation is described in detail in the background art of Patent Document No. 10-1761561.

그리고 외부 온도가 낮은 겨울철에는 너무 낮은 온도로 인해 ESS시스템이 정상적으로 작동하지 않는 문제가 있다.And in winter when the outside temperature is low, there is a problem that the ESS system does not operate normally due to too low a temperature.

이때는 액체가 순환되는 수로 어느 부분을 차단하여 액체가 순환하지 않도록 하는 것이 바람직하다.At this time, it is preferable to block any part of the water through which the liquid is circulated so that the liquid does not circulate.

다음 구성의 실시예를 살펴보면 다음과 같다.Looking at the embodiment of the following configuration is as follows.

상기 제2수로관(20) 내지는 환수구(11)를 배터리(3)를 커버하는 케이스(50) 벽에 밀착시켜 케이스벽과 열교환이 이루어지도록 하는 구성을 특징으로 한다.It is characterized in that the second water pipe (20) or the water outlet (11) is in close contact with the wall of the case (50) covering the battery (3) to exchange heat with the case wall.

상기 구성의 실시예를 살펴보면 다음과 같다.Looking at the embodiment of the configuration is as follows.

상기 제2수로관(20) 내지는 환수구(11)를 케이스(50) 벽과 밀착시키면 케이스와 열교환이 이루어지고 케이스의 열은 외부공기에 의해 방열된다.When the second waterway pipe 20 or the return opening 11 is in close contact with the wall of the case 50, heat exchange with the case is achieved and heat of the case is dissipated by external air.

이처럼 케이스로부터 방열하게 되면 방열 효과가 더 있다.When the heat is radiated from the case, there is a heat dissipation effect.
