In general, cooling modules have been used for furnace cooling of metal melting furnaces (electric furnaces and chemical fuel furnaces).

Conventional cooling modules are designed and manufactured with a large capacity, and the material and shape of the heat transfer tube and the material and shape of the fins are materials and shapes that can withstand high heat. In addition, since the conventional cooling module is installed in a large factory, it is not limited to noise, vibration, or electricity consumption.

Conventional cooling module devices have a heavy weight due to large size compared to efficiency. Due to the large size, the cooling module device must be disassembled and moved when transporting, and it takes a long time to re-install, and there are restrictions on the use of the surrounding space. In addition, as the size of the fan increases, the size of the driving fan also increases, resulting in greater noise and vibration.

Due to this problem, the installation site must be installed far away from the residence, and even if electricity is produced from the generator, the initial cost of equipment and equipment to be transmitted to the residence is high.

Therefore, recently, efforts are being made to install a cooling module device in a place close to a city rather than a factory area.

Advantages and features of the present invention, and methods of achieving them, will become clear with reference to the detailed description of the following embodiments taken in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and only these embodiments make the disclosure of the present invention complete, and common knowledge in the art to which the present invention belongs. It is provided to fully inform the holder of the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numbers designate like elements throughout the specification.

Hereinafter, a cooling module device using a fin tube and a driving fan according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A general cooling module device is manufactured and used in two types. The first type is a forced draft type, which is a cooling module device in which a driving fan is installed at the bottom of the radiator to suck in outside air through the driving fan and blow it into the radiator.

An advantage of the cooling module device is that power consumption of the driving fan is small. Since the air resistance on the inlet side of the driving fan is small, the current resistance acting on the driving fan is reduced, so that it can be driven even with a small current. However, such a cooling module device has a disadvantage in that the cooling effect is reduced due to recirculation and crosswind of air passing through the radiator.

The second type is the induced draft type, which is a cooling module in which a driving fan is placed on top of the radiator to discharge outside air passing through the radiator to the driving fan. The advantages of this cooling module are air recirculation and crosswind not affected by In addition, air and heat can be evenly distributed to the radiator to increase efficiency. However, the power consumption of the driving fan is high, and the hot air heat-exchanged by the radiator directly acts on the driving unit (motor), so when selecting the driving unit (motor), it is necessary to have an expensive driving unit with high efficiency. In addition, since the driving fan is located above the radiator, maintenance and replacement of the radiator and the driving fan are difficult.

The common disadvantage of the above two types of radiators is the part where the radiator is installed horizontally with the floor. When the radiator is level with the floor, the flow rate of the fluid through the radiator slows down. The reason is that the flow rate of the fluid passing through the radiator is fixed, but the passage area is wide, so the speed of the fluid slows down and the circulation period of the fluid decreases. At this time, a situation may occur in which the flow rate and temperature required by the power generation facility cannot be properly supplied.

The present invention has a structure that not only protects the above two types of disadvantages, but also has all the advantages. In the cooling module device of the present invention, a radiator is installed vertically with the floor, and a driving fan is located at a rear end spaced apart from the radiator. Therefore, since it has uniform temperature and air distribution, which are advantages of the induced draft type, efficiency can be increased.

In addition, in the cooling module device of the present invention, since the radiator is installed vertically and is not exposed to solar heat, it is easy to control the temperature of the fluid in the pipe because the heat load is small. At this time, power consumption can be reduced by lowering the number of revolutions of the driving fan using an inverter.

In addition, since the cooling module device of the present invention has radiators installed on both sides vertically from the ground, it is possible to reduce power consumption by minimizing air resistance by widening the passage area of outdoor air.

In addition, the cooling module device of the present invention has a driving fan installed at the rear end of the radiator, so that it is not affected by cross wind and there is no recirculation of exhaust air.

Therefore, in the cooling module device of the present invention, it is easy to replace and repair the radiator and the drive unit, which are disadvantages of the induced draft type.

This will be described in detail through a cooling module device using a fin tube and a driving fan according to an embodiment of the present invention with reference to the accompanying drawings.

1 to 5, the cooling module device 100 using a fin tube and a driving fan according to an embodiment of the present invention is to be installed in a place close to a city rather than a factory zone, considering noise and vibration. It is a new type.

A cooling module device 100 using a fin tube and a driving fan according to an embodiment of the present invention includes a lower base 120 , a radiator 140 and a driving fan 160 .

The lower base 120 is fixedly installed parallel to the ground. The lower base 120 may be fixedly installed by the installation structure 105 .

The radiator 140 is fixedly installed on the lower base 120 so as to be coupled to both sides in a vertical direction crossing the lower base 120, and the heat transfer tube 143 through which the cooling fluid circulates and the heat transfer tube 143 are lattice. It is mounted so as to be wrapped in a molded plate structure and has a heat dissipation fin 144 for heat exchange with external air.

At least one driving fan 160 is installed. The driving fan 160 is located at the rear end between the front ends of the radiators 140 on both sides adjacent to the lower base 120 and the radiators 140 on both sides spaced apart from each other.

The driving fan 160 includes an electric motor 161, a motor case 162, an impeller 163, a suction bell 166, and an air passage case 167.

The electric motor 161 is a motor for generating power for driving the driving fan 160 .

The motor case 162 is mounted to accommodate the motor 161. The motor case 162 is preferably formed of an aluminum alloy material capable of lowering the resistance value of the motor 161.

The impeller 163 is coupled to the electric motor 161 and receives power from the electric motor 161 to rotate.

The suction bell 166 is coupled to the motor case 162 and installed to suck air.

The air passage case 167 is coupled to the motor case 162 and the suction bell 166 to form an empty space for passing air therein.

In addition, the driving fan 160 is mounted on one side wall of the air passage case 167 and is coupled with the motor connection terminal box 168 for controlling the driving of the electric motor 161 and the air passage case 167, A motor repair door 164 covering the motor 161 and the impeller 163 and a safety net 165 covering the top of the motor repair door 164 may be further included.

The radiator 140 includes an upper case 141, a lower case 142, a heat transfer tube 143, a heat dissipation fin 144, a connection tube 145, a header 146, a drain pipe 148 and an intake pipe 151 ).

The upper case 141 is coupled to the lower case 142 to form an empty space therein.

The heat transfer tube 143 is disposed inside the upper and lower cases 141 and 142 to provide a passage through which the cooling fluid circulates.

The heat dissipation fin 144 is mounted to surround the heat transfer tube 143 in a lattice-like plate structure to exchange heat with external air.

As such, the present invention generates heat exchange with tens to hundreds of heat transfer tubes 143 and heat radiation fins 144, and uses a forced convection driving fan 160 to increase heat exchange efficiency to increase heat exchange efficiency. It becomes possible to maintain the target fluid temperature at a desired temperature.

The connection tube 145 is connected to the outlet side of the heat transfer tube 143 and is mounted to discharge the cooling fluid to the outside of the heat transfer tube 143.

The header 146 is coupled to the connecting tube 145 to fix the connecting tube 145.

The drain pipe 148 is coupled to the header 146 and is mounted to drain the cooling fluid circulating inside the heat transfer tube 143 . In addition, the intake pipe 151 is connected to the inlet side of the heat transfer tube 143, and is mounted to supply cooling fluid to the inside of the heat transfer tube 143.

In addition, the radiator 140 is mounted on the drain pipe 148, coupled to the air vent 147 for discharging air, and the outer circumferential surface of the drain pipe 148, the drain flange for fixing the drain pipe 148 ( 149), the drain 153 attached to the inlet pipe 151, the inlet flange 150 coupled to the outer circumferential surface of the inlet pipe 151 and fixing the inlet pipe 151, and the heat transfer tube 143 It further includes a U bending 155 mounted on both sides of the curved surface and a U bending case 156 covering and protecting the U bending 155.

In addition, the radiator 140 may further include a cooling air distribution plate 152 and a heat dissipation fin insulation case 154 .

The cooling air distribution plate 152 is mounted to be coupled to the upper and lower cases 141 and 142 to uniformly distribute the cooling air. The radiating fin warming case 154 is mounted to surround the radiating fin 144 and insulates the radiating fin 144 .

The cooling module device 100 using the fin tube and the driving fan in the above-described embodiment of the present invention includes a lower case 120, a radiator 140, and a driving fan 160 as well as a radiator safety case 110 and a pressure control unit. It may further include an expansion tank (not shown), a pressure gauge (not shown), a thermometer (not shown), and other small accessories.

As described above, the radiator 140 is a tube composed of rows and stages, and the cooling capacity suitable for the use conditions can be changed by changing the columns and stages according to the use conditions. In addition, the driving fan 160 is made of an aluminum alloy material capable of maximizing air volume and air pressure and lowering the resistance value of the electric motor 161 . As the electric motor 161, it is preferable to use a high-efficiency inverter motor. It is preferable to use a motor of a grade that can be used outdoors for the motor 161, and replacement and repair are made easy by selecting a motor that can be purchased in general rather than custom-made.

An inverter for driving the driving fan 160 is installed in the motor connection terminal box 168, and since the number of driving fans 160 may be installed in plurality according to the capacity of the cooling module device 100, the driving fan A plurality of inverters proportional to the number of (160) are required. In addition, the plurality of driving fans 160 can be independently driven. That is, even if one of the plurality of driving fans 160 stops operating, the other driving fan 160 can perform the fluid cooling operation.

The reason for this design is that since the power generation facility continuously generates power for 24 hours, when the cooling operation stops, the performance of the generator deteriorates, making it impossible to generate power. Therefore, it is preferable to manage each driving fan 160 independently so as not to stop the cooling operation.

The inverter installed in the motor connection terminal box 168 cuts off the power of the stopped driving fan 160, and the other driving fan 160 divides the work of the stopped driving fan 160 to operate. The inverter receives the temperature from a thermometer that measures the temperature of the cooling fluid passing through the cooling module device 100 and adjusts the number of revolutions. In this way, the cooling module device 100 should continuously provide an appropriate temperature and flow rate of the cooling fluid to the generator while the generator is operating.

Since the cooling module device 100 is installed outdoors, the radiator safety case 110 may be corroded by rain or snow. Therefore, the radiator safety case 110 uses a corrosion-resistant galvanized steel sheet and has internal reinforcement to withstand impact from the outside.

The expansion tank for pressure control determines the pressure and flow rate of the tank according to the flow rate used, and the expansion tank for pressure control uses a product that has obtained a certificate from the Korea Occupational Safety and Health Administration.

The installation structure 105 must be able to withstand the weight of the cooling module device 100 and is manufactured to withstand vibration caused by the driving fan 160 . The driving fan 160 and the motor repair door 164 are installed in a vertical direction with the radiator 140 of the cooling module device 100 . When the driving fan 160 is out of order, the motor repair door 164 is opened and the driving fan 160 or the motor 161 is repaired. The motor repair door 164 has a well-sealed structure to protect the motor 161 or the driving fan 160 by preventing foreign matter from entering during normal operation of the cooling module device 100 .

The drain pipe 148 and the intake pipe 151, which are connecting pipes of the radiator 140, are very important pipes for sending the fluid circulated from the generator to the radiator 140 and supplying the cooled cooling fluid back to the generator. The drain pipe 148 and the water intake pipe 151 are preferably made of stainless steel or copper depending on the purpose. In the middle of the pipe, the pipe for the expansion tank is also included. The internal pressure of the radiator 140, the pipe, and the power generation facility must always be constant, and the pipe diameter and material capable of withstanding the internal pressure are selected.

The pressure gauge is installed in the pipe between the rear end of the drain pipe 148 and the intake pipe 151 of the radiator 140 and the expansion tank. When the pressure of the pressure gauge is checked, it can be seen that a crack has occurred in the heat transfer tube 143 of the radiator 140 when the pressure is lower than the normal pressure. When the pressure of the pressure gauge is higher than the normal pressure, it occurs when the driving fan 160 malfunctions or when the temperature of the fluid circulated and supplied from the generator is higher than the design temperature. At this time, an abnormal signal buzzer is placed in the motor connection terminal box 168 so that the driving fan 160 can be checked and managed.

It is desirable to store a surplus of fluid (about 65wt% of the expansion tank) to compensate for the lack of fluid due to leaks in the expansion tank for pressure control. in order to allow The thermometer may check the state of the generator by measuring the temperature of the fluid entering the cooling module device 100 and the temperature of the fluid passing through the cooling module device 100, and the temperature of the fluid circulated to the generator may be measured according to usage conditions. It is an important component for adjusting the rotational speed of the electric motor 161 of the driving fan 160 so that it can be adjusted accordingly.

Since the temperature of the generator fluid is directly related to the performance of the generator, it is preferable to operate the cooling module device 100 by programming a process for driving the motor by connecting the temperature controller and the inverter.

As described above, the cooling module device using the fin tube and the driving fan in the embodiment of the present invention can compensate for the disadvantages of the existing cooling module device and can respond to the miniaturization of power generation facilities and residentialization of power generation places.

Currently, various power generation facilities by hydrogen are being developed. Several large domestic companies are developing generators and power plants using hydrogen. It is installed and operated in some regions in Korea.

Hydrogen power generation can be miniaturized, unlike power generation such as solid fuel, nuclear power, and hydropower, but the electricity generation capacity does not show a large difference compared to power generation such as solid fuel, nuclear power, and hydropower.

In addition, in recent years, it will be changed into a power plant capable of generating power while maintaining a clean environment free from problems such as environmental problems and nuclear hazards. Accordingly, there is a need for a cooling module device for efficiency and maintenance of power generation facilities, and the present invention is a cooling module device that is very suitable for application to the above power plants.

Next, if there is no problem with electricity, check whether there is circulating fluid inside the radiator and whether an appropriate amount of cooling fluid is filled. At this time, the method of checking the circulating fluid is checked through the pressure of the expansion tank and the flow meter.

Next, when an appropriate amount of circulating fluid is filled, the driving fan is initially driven. At this time, when the driving of the driving fan is normalized, the circulating fluid circulation pump is operated to circulate the fluid inside the generator to the radiator.

Next, adjust the air volume (rotation speed) of the driving fan while checking the thermometer. Here, since the temperature of the outside air is different depending on the summer season and the winter season, it is preferable to program the thermostat so that it can be operated by temperature during the summer season and winter season by setting the power used during the summer season and winter season. In addition, when the cooling module device of the present invention is not in use, the primary power is cut off as much as possible, and the circulating fluid inside the radiator is stored by maintaining only 90wt% of the appropriate fluid. At this time, the cooling module device of the present invention is compact and can be moved and used at any desired location without being fixed to one place. In this way, depending on where the generator is used, the cooling module device of the present invention may also be used.

In addition, the cooling module device using the fin tube and the driving fan according to the embodiment of the present invention does not have a structure in which the driving fan is located above and below the horizontal radiator, but the driving fan is located between the vertical radiators.
