본 발명은 각종 유도가열장치의 내부에 장착되는 냉각장치의 냉각코일에 관한 것이다.The present invention relates to a cooling coil of a cooling device mounted inside of various induction heating devices.

이를 좀더 상세히 설명하면, 각종 유도가열장치의 내부에 설치되어 순환냉각수가 순환되고, 상측에 설치된 살수관의 노즐을 통해 냉각수가 살포되어 열교환되는 주름이 외면에 형성된 원형냉각코일에 있어; 주름이 연속적으로 형성된 상기 원형냉각코일은 단면상으로 보아 상하 높이를 좌우 폭보다 상대적으로 크게 형성한 타원형냉각코일이 장착된 유도가열장치용 냉각코일을 제공하려는 것이다.In more detail, the circular cooling coil is installed in the induction heating apparatus is circulated cooling water is circulated, the cooling water is sprayed through the nozzle of the sprinkler pipe installed on the upper side of the circular cooling coil formed on the outer surface; The circular cooling coil in which the corrugation is continuously formed is to provide a cooling coil for an induction heating apparatus equipped with an elliptical cooling coil having an upper and lower height relatively larger than a left and right width as viewed in cross section.

일반적으로 유도가열장치는 모재를 성형 또는 변형하여 기계를 제작하거나 제품을 생산하는 것으로 이와 같이 재료를 가공함에 있어서 각 유도가열장치의 각 기계구성에 인가되는 고전압 또는 고주파에 영향을 받아 가열되고 이렇게 가열된 열은 각 기계구성은 열팽창 또는 적정수준의 가공상태를 형성하지 못하여 가공오차 및 오동작을 유발함으로써, 제작되는 제품의 불량을 초래하게 된다.In general, induction heating apparatus is to make a machine or produce a product by molding or modifying a base material, and in processing such materials, it is heated under the influence of high voltage or high frequency applied to each machine configuration of each induction heating apparatus. The heat generated causes mechanical errors and malfunctions due to the inability of each machine to form thermal expansion or processing at an appropriate level, resulting in product defects.

따라서 상기에 이유로 유도가열장치의 각 구성부위를 일정온도로 유지시키기 위한 냉각시스템이 구비하게 되는데 공냉법(空冷法)과 수냉법(水冷法)을 사용한다.Therefore, for this reason, a cooling system for maintaining each component of the induction heating apparatus at a constant temperature is provided, which uses an air cooling method and a water cooling method.

상기 공냉법(空冷法)의 경우에는 열이 주로 몰리는 부위에 팬이 장착된 모터를 설치하고 내부의 열을 외부로 강체유출시켜 내부에 열을 식히는 방식으로, 일정시간 동안에는 열을 강제로 유출시켜 줄 수 있으나, 시간이 경과 함에 따라 소음 및 진동을 심하게 유발하고 오작동을 일으킬 수 있는 단점이 있어, 수냉법(水冷法)에 의한 방법을 주로 사용한다.In the case of the air-cooling method, by installing a motor equipped with a fan in a place where heat is mainly driven, and cooling the heat inside by discharging the heat inside to the outside, the heat is forced out for a predetermined time. It can give, but with the disadvantage that it may cause noise and vibration severely and malfunction as time passes, the method by water cooling method is mainly used.

수냉법(水冷法)은 각 기계의 구성부분에 냉각파이프를 설치시켜 주고, 이 설치된 냉각파이프를 통하여 순환냉각수를 강제 유동시켜 각 기계의 구성부분에서 발생 되는 열을 식혀주도록 하는 것으로 통상적으로 많이 사용되고 있으나, 이 또한 열을 신속하게 식혀주는 면에서는 미진한 부분이 있다.The water cooling method is commonly used to install cooling pipes in the components of each machine and to force the flow of circulating cooling water through the installed cooling pipes to cool the heat generated in the components of each machine. However, this also has a weak point in terms of cooling the heat quickly.

상기와 같은 문제를 해소하기 위하여 본인은 국내의 등록특허 제10-478815를 제안한바 있다.In order to solve the above problems, I have proposed domestic registered patent No. 10-478815.

상기의 등록특허 제10-478815 “유도가열장치용 냉각수 냉각장치”를 간단하게 설명하면, 하우징의 내부를 구획하여 일측에는 냉각실을 구비하고, 타측에는 송풍기를 장착하며, 냉각실의 하단일측에는 저수조를 구비하고, 저수조의 일측에는 냉각수압송펌프를 장착하여 저수조의 냉각수를 냉각실의 상측에 장착된 살수관에 압송하며, 냉각실의 중앙에 냉각코일을 구성하여 순환냉각수를 냉각코일에 순환시키고 냉각코일에는 살수관의 노즐을 통하여 냉각수를 냉각코일에 살포하며 송풍기에 의해 공기압을 냉각코일에 공급하여 냉각코일에서 열교환을 실시하도록 하는 냉각장치에 있어서, 상기 냉각실의 상측에 상판을 씌워 구비하되, 상기 상판의 내측에 복수 개의 지지대를 형성하고, 지지대가 설치된 상판의 부분에는 유통공을 형성하며, 상기 지지대에는 모터를 장착하고, 모터의 구동축에는 통상의 팬을 장착한 배풍기를 장착한 것과, 상기 냉각실의 하측에는 구비된 저수조의 일측에는 전면 및 배면에 흡입통풍구를 설치하는 것이 더 포함되는 것을 특징으로 하는 유도가열장치 용 냉각수 냉각장치에 관한 것이다.The above-described Patent No. 10-478815 “Cooling Water Cooling Device for Induction Heating Device” is briefly described. The inside of the housing is partitioned, and a cooling chamber is provided at one side, and a blower is mounted at the other side. It is equipped with a water tank, and one side of the water tank is equipped with a cooling water pressure pump to pump the cooling water of the water tank to the sprinkling pipe mounted on the upper side of the cooling chamber, and to form a cooling coil in the center of the cooling chamber to circulate the cooling water to the cooling coil The cooling coil is sprayed with cooling water through the nozzle of the spray pipe to the cooling coil, and a cooling device for supplying air pressure to the cooling coil by a blower to perform heat exchange in the cooling coil, the upper plate of the cooling chamber is provided with Forming a plurality of supports on the inner side of the top plate, and forming a distribution hole in the portion of the top plate on which the support is installed, the support It is equipped with a motor, and the drive shaft of the motor is equipped with an air blower equipped with a normal fan, and one side of the water reservoir provided in the lower side of the cooling chamber further comprises a suction vent on the front and back It relates to a cooling water chiller for an induction heater.

상기의 발명은 각 기계의 구성부분에서 발생 되는 열을 신속하게 식혀 줄 수 있어, 제품의 오작동 및 기계부품의 과부하를 방지하여 제품을 불량률(不良率)을 감소시켜준다. The above invention can quickly cool the heat generated in the components of each machine, thereby preventing the product malfunction and overload of the machine parts to reduce the defective rate of the product (제품 良 不).

하지만, 공정이 빠르게 돌아가게 되면 순환냉각수의 온도가 상승하게 되고 상승된 온도는 냉각코일을 거쳐 유동 되더라도 일정한 온도 이하로 더 낮출 수 없어 냉각수배송관을 통해 배출된 순환냉각수는 기계부품의 온도를 미온하게 낮춰주어 기계부품에 과부하가 발생하는 문제가 있다.However, if the process runs fast, the temperature of the circulating coolant rises and the elevated temperature cannot be lowered below a certain temperature even though it flows through the cooling coil. There is a problem that the overload occurs on the machine parts by lowering.

본 발명은 상기와 같은 문제를 해소할 수 있도록 된 유도가열장치용 냉각코일을 제공하려는 것이다.The present invention is to provide a cooling coil for an induction heating apparatus that can solve the above problems.

본 발명의 다른 목적은, 단면상의 형상이 타원형이고 외면에 주름을 연속적으로 형성한 타원형냉각코일을 지름이 넓은 부분을 장착틀에 길이방향으로 장착시켜 줌으로써, 주름의 외주면으로 열이 발생하도록 유도하여 살포된 냉각수가 냉각 코일의 외면을 따라 이동할 때 열 교환이 신속하게 일어나도록 유도하며, 또한 타원형이므로 외면에 살포되는 냉각수가 도포되는 단위면적이 넓게 되어 배출되는 순환냉각수의 온도를 용이하게 낮춰줄 수 있는 유도가열장치용 냉각코일을 제공하려는 것이다.Another object of the present invention, by elliptical cooling coil having an elliptical shape on the cross-section and continuously formed pleats on the outer surface by mounting a wide diameter portion in the mounting frame in the longitudinal direction, to induce heat to be generated on the outer peripheral surface of the pleats When the sprayed coolant moves along the outer surface of the cooling coil, the heat exchange takes place quickly and it is also elliptical, so the unit area to which the coolant sprayed on the outer surface is widened can easily reduce the temperature of the circulating coolant discharged.

It is to provide a cooling coil for induction heating apparatus that can reduce the cost.

In addition, Figure 4 is an exemplary view showing a non-frictional portion generated by air cooling and water cooling in the conventional cooling coil (2) for induction heating apparatus.

케이스(4)의 중간부분을 구획판으로 구획하였고, 구획판에 의해 구획된 하측 공간부에는 냉각수를 수집하여 저장하는 집수조(12) 및 수집된 냉각수를 상부에 설치된 살수파이프(13)로 압송시켜주도록 냉각수공급관(10)이 형성된 펌프(11)를 설치하였다.The middle part of the case 4 was partitioned by a partition plate, and the lower space partitioned by the partition plate was pumped into the water collecting tank 12 for collecting and storing the cooling water and the collected cooling water to the sprinkling pipe 13 installed at the upper portion. The pump 11 in which the cooling water supply pipe 10 was formed was installed.

상기 구획판의 상부에는 순환냉각수가 유입되고 유출될 수 있도록 냉각수유입관(8) 및 냉각수배송관(9)를 각각 형성하되, 상기 냉각수유입관(8)과 냉각수배송관(9)의 일측으로 복수 개의 유도가열장치용 냉각코일(1)을 각각 형성하였다. Cooling water inlet pipe (8) and the cooling water delivery pipe (9) is formed in the upper portion of the partition plate so that the circulation coolant flows in and out, respectively, to one side of the cooling water inlet pipe (8) and cooling water delivery pipe (9) A plurality of cooling coils 1 for induction heaters were formed, respectively.

상기 본 발명에 따른 유도가열장치용 냉각코일(1)은 다음과 같이 구성하였다.The cooling coil 1 for induction heating apparatus according to the present invention was configured as follows.

단면상으로 보아 타원형으로 형성하되, 상하 높이가 좌우 폭보다 상대적으로 큰(높은) 타원형상의 타원형냉각코일(3)로 형성하였고, 타원형냉각코일(3)의 내부(내면)는 매끄럽게 형성하고 외부(외면)는 주름(3-1)을 연속적으로 형성하였다.It is formed into an elliptical shape as viewed in cross section, and is formed of an elliptical cooling coil (3) having an elliptical shape having a higher (higher) height than the left and right widths. ) Continuously formed wrinkles 3-1.

상기와 같이 타원형냉각코일(3)의 외부(외면)에 주름(3-1)을 형성시켜 주어 타원형냉각코일(3)의 내부를 유동하는 따뜻한 순환냉각수의 열이 주름(3-1)의 외면으로 유도되도록 하고, 주름(3-1)으로 유도되는 열기가 살수관(13)을 통해 살포되는 냉각수와는 열 교환이 신속하게 일어나도록 하였다.
또한 타원형냉각코일(3)을 단면으로 보아 상하 높이가 좌우 폭보다 상대적으로 큰(높은) 타원형으로 형성하여 줌으로서, 살포된 냉각수가 타원형냉각코일(3)의 외면(3-1)을 따라 흐를 때 마찰면적 즉, 냉각수가 도포 되면서 흐를 때의 면적을 증가시켜 내부의 순환냉각수와의 열교환면적을 크게하여 열 교환이 효율적으로 이루어지고, 냉각수배송관(9)을 통해 배출되어 재차 배송되도록 하였다.
As described above, the outer (outer surface) of the elliptical cooling coil (3) forms a wrinkle (3-1), the heat of the warm circulation cooling water flowing inside the elliptical cooling coil (3) is the outer surface of the wrinkle (3-1) The heat induced in the pleats (3-1) is to be quickly exchanged with the cooling water sprayed through the sprinkling pipe (13).
In addition, the elliptical cooling coil (3) is viewed in cross section, and the upper and lower heights are formed to be larger (higher) than the left and right widths so that the sprayed cooling water flows along the outer surface (3-1) of the elliptical cooling coil (3). When the friction area, that is, when the cooling water is applied to increase the flow area to increase the heat exchange area with the circulating coolant inside the heat exchange is made efficiently, and discharged through the cooling water delivery pipe (9) to be shipped again.

또한, 도 3과 같이 타원형냉각코일(3)의 경우에는 마찰부분(면적)을 증대시키고, 반면에 비마찰부분(b부분)의 간격을 협소하게 형성하게 된다.In addition, in the case of the elliptical cooling coil 3, as shown in FIG. 3, the friction part (area) is increased, while the gap between the non-friction part (b part) is narrowly formed.

따라서, 코일의 상부와 중간부에서만 이루어지던 열교환이 코일의 하부에서도 이루어지게 되므로 열교환(냉각)효율을 증가시킬 수 있게 된다. Therefore, the heat exchange, which is performed only at the upper and middle portions of the coil, is also performed at the lower portion of the coil, thereby increasing heat exchange (cooling) efficiency.

이하 본 발명에 따른 유도가열장치용 냉각코일(1)의 설치상태 즉, 실시상태를 설명한다.Hereinafter, the installation state, that is, the implementation state of the cooling coil 1 for induction heating apparatus according to the present invention.

제어부(c)를 조작하여 양정펌프(11)가 작동을 하게 되면서 집수조(12)에 유입된 냉각수를 냉각수공급관(10)를 통해 강제로 압송하여 좌우로 노즐(14)이 형성된 살수관(13)으로 이동됨과 동시에 냉각수유입관(8)으로는 다열로 배열된 타원형냉각코일(3) 내부로 소정의 온도를 가진 순환냉각수가 유동하게 된다.The water pump (13) having the nozzle (14) formed at the left and right by forcibly feeding the cooling water introduced into the water collecting tank (12) through the cooling water supply pipe (10) while the pump (11) operates by operating the control unit (c). At the same time, the circulating coolant having a predetermined temperature flows into the elliptical cooling coil 3 arranged in multiple rows through the cooling water inlet pipe 8.

상기의 순환냉각수의 열을 식혀주기 위해 살수관(13)으로 압송된 냉각수는 노즐(14)을 통해 분사되고 분사된 냉각수는 타원형코일(3)의 주름(3-1)에 도포되면서 열교환을 시작한다.The cooling water pumped to the water spray pipe 13 to cool the heat of the circulating cooling water is injected through the nozzle 14 and the injected cooling water is applied to the pleats 3-1 of the elliptical coil 3 to start heat exchange. do.

또한, 상기의 열 교환이 신속하게 이루어지도록 살수관(13)의 상측에는 방열판(구체적으로 도시하지 않음)을 형성시켜주고 방열판으로 이동된 열은 케이스(4)의 상단에 형성된 모터(15)의 팬(16)을 통해 밖으로 배출되게 되며, 통풍구(17)을 통해서는 차가운 외기를 내측으로 유입시켜 다중으로 열을 식혀 주도록 하였다.In addition, the heat exchanger (not specifically shown) is formed on the upper side of the sprinkling pipe 13 so that the heat exchange is quickly performed, and the heat transferred to the heat sink is applied to the upper portion of the case 15 of the motor 15. It is to be discharged out through the fan 16, through the vent 17 to cool the outside air to the inside to cool the heat in multiple.

온도가 떨어진 순환냉각수는 냉각수배송관(9)를 통해 다시 배출되고 이러한 일련의 과정을 반복되도록 하였으며, 도 2a와 같이 도시하였다.The circulating coolant whose temperature has fallen is discharged again through the coolant delivery pipe 9 and repeated this series of processes, as shown in FIG. 2A.

또한, 에어 또는 냉각수를 아래에서 위로 쏴주거나 위에서 아래도 분사하여 냉각을 시켜주는 경우 원형냉각코일(2)의 하부 또는 상부에는 찬 공기 또는 냉각수가 연속적으로 마찰을 일으켜 열 교환을 빠르게 진행되지만, 상면 또는 하부에는 비마찰부분, 즉 a부분이 넓게 발생 되어 열 교환이 미비하게 이루어지며 이를 도 4와 같이 도시 하였다.
이와 반대로 타원형냉각코일(3)의 경우에 마찰부분은 증대시키고 비마찰부분, 즉 b부분을 극간을 협소하게 형성시켜 주어 열 교환이 상부와 중간부에만 이루어지던 것을 하부에서도 발생되도록 하여 냉각효율을 증가시키도록 하였으며 이를 도 3과 같이 도시 하였다.
In addition, when the air or coolant is shot from the bottom up or the top is blown down to cool the air, the coolant or the coolant continuously frictions the lower or upper portion of the circular cooling coil 2, but the heat exchange proceeds rapidly. Alternatively, a non-friction part, that is, a part is widely generated in the lower part, so that heat exchange is inadequate, which is illustrated in FIG. 4.
On the contrary, in the case of the elliptical cooling coil (3), the friction part is increased and the non-friction part, that is, the b part is formed narrowly, so that the heat exchange occurs only at the upper part and the middle part at the lower part, thereby improving cooling efficiency. This is shown as shown in FIG.

본 발명은 기재된 구체적인 예에 대하여만 상세히 설명되었지만 본 발명의 기술사상범위 내에서 변형 및 수정할 수 있음은 당업자에게 있어 당연한 것이며, 이러한 변형 및 수정이 첨부된 특허청구범위 내에 속함은 당연한 것이다.Although the present invention has been described in detail only with respect to the specific examples described, it will be obvious to those skilled in the art that modifications and variations can be made within the technical scope of the present invention, and such variations and modifications are within the scope of the appended claims.

본 발명은 각종 유도가열장치의 내부에 장착되는 냉각장치의 냉각코일에 관한 것으로, 각종 유도가열장치의 내부에 설치되어 순환냉각수가 순환되고, 상측에 설치된 살수관의 노즐을 통해 냉각수가 살포되어 열교환되는 주름이 외면에 형성된 원형냉각코일에 있어서; 주름이 연속적으로 형성된 상기 원형냉각코일은 단면상으로 보아 상하 높이를 좌우 폭보다 상대적으로 크게 형성한 타원형냉각코일로 형성하여 줌으로써; 주름의 외주면으로 열이 발생하도록 유도하여 살포된 냉각수가 냉각코일의 외면을 따라 이동할 때 열 교환이 신속하게 일어나도록 유도할 수 있고, 또한 외면에 살포되는 냉각수의 단위면적을 넓혀주어 배출되는 순환냉각수의 온도를 신속하게 낮춰줄 수 있는 있으며, 또한 종래의 냉각코일의 길이보다 20%작게 형성하여 설치시켜 주더라도 순환냉각수의 온도를 용이하게 낮춰줄 수 있으며, 뿐만 아니라 냉각코일의 자제가 적게 들어감으로 제조원가를 절감시켜 줄 수 있다.The present invention relates to a cooling coil of a cooling apparatus mounted in various induction heating apparatuses, and is installed inside various induction heating apparatuses, and circulating cooling water is circulated, and the cooling water is sprayed through a nozzle of a sprinkling pipe installed at an upper side to exchange heat. In the circular cooling coil is formed wrinkles on the outer surface; The circular cooling coil in which wrinkles are formed continuously is formed by an elliptical cooling coil having a vertical height relatively larger than a left and right width as viewed in cross section; Circulating coolant discharged by inducing heat to the outer circumferential surface of the corrugation so that heat exchange can occur quickly when the sprayed cooling water moves along the outer surface of the cooling coil, and also widens the unit area of the cooling water sprayed on the outer surface. The temperature of the cooling water can be lowered quickly, and the temperature of the circulating cooling water can be easily lowered even if the installation is made 20% smaller than the length of the conventional cooling coil. It can reduce manufacturing cost.
