Detailed Description
Next, the cooling module of the present invention will be described in detail with reference to the drawings.
Fig. 2 to 5 are an assembled perspective view, an exploded perspective view, and a front sectional view illustrating a cooling module according to an embodiment of the present invention, and fig. 6 to 8 are a left side view, a right side view, and a lower side plan view illustrating the cooling module according to an embodiment of the present invention.
As shown in the drawings, a cooling module according to an embodiment of the present invention may be constituted to substantially include: a fluid reservoir 100, a screw pump 200, and a reversing valve 300, and may also include a controller 400.
The liquid storage tank 100 may function to store the cooling water and then supply the cooling water to the screw pump 200. The liquid storage tank 100 may be formed with an empty space therein to be able to store the cooling water, and the liquid storage tank 100 is combined with a gland 110 at an upper surface thereof, and the pressure inside the liquid storage tank 100 may be adjusted by the gland 110. And the reservoir tank 100 may be formed at a side surface side with a cooling water inlet portion 120 to receive inflow of cooling water from a radiator or the like, and the side surface side of the reservoir tank 100 may be formed with a communication hole to communicate with an outlet port of the direction valve 300 to receive inflow of cooling water. Here, the inner space of the reservoir tank 100 is formed as one communicating space without a partition wall for division, so that the cooling water can be accommodated in a single space without being separated in the interior of the reservoir tank 100.
The screw pump 200 is a cooling water pump that can receive cooling water from the reservoir tank 100 and send the cooling water to a place where it is needed, and the screw pump 200 may be provided with only 1. The screw pump 200 is a pump of a type in which fluid is pumped by a change in volume between screws while the screws are rotating in mesh. The screw pump 200 is disposed and coupled to a lower end of one side surface of the reservoir tank 100, and a cooling water inlet 210 of the screw pump 200 is connected to the reservoir tank 100, so that cooling water in the reservoir tank 100 can smoothly flow into the screw pump 200. Here, the pump mount 130 is formed to be recessed on the lower side surface side of the reservoir tank 100, and the pump 202 of the screw pump 200 can be inserted into the pump mount 130 and coupled thereto. Further, a cut groove 140 is formed in the partially removed state in the pump mounting portion 130 of the accumulator 100, and a cooling water discharge port 220 of the screw pump 200 can be inserted and disposed in the cut groove 140. Therefore, the cooling water discharge port 220 of the screw pump 200 can be easily led out to the outside through the slit groove 140. Further, the reservoir tank 100 is formed with the cooling water outlet 150 recessed downward from the bottom, and the cooling water outlet 150 communicates with the inside of the pump mounting portion 130, whereby the cooling water inlet 210 of the screw pump 200 can be inserted and disposed in the cooling water outlet 150 to communicate therewith. Therefore, since the cooling water inlet 210 of the screw pump 200 is connected to the cooling water outlet 150 disposed at the lowermost end in the gravity direction, the cooling water can smoothly flow into the screw pump 200.
The direction change valve 300 is a valve that can change the flow direction of the cooling water according to the operation, and may be coupled to the reservoir tank 100, and the outlet port 320 is connected to and communicates with the reservoir tank 100. Also, the outlet port 320 of the directional valve 300 may be connected to a side surface side of the fluid reservoir tank 100. The direction change valve 300 may be disposed on a side surface of the reservoir tank 100 opposite to the screw pump 200 with reference to the reservoir tank 100. In addition, the direction valve 300 may be formed with a plurality of inlet ports 310, and a plurality of outlet ports 320. Here, the inlet port 310 may also function as both an inlet and an outlet depending on the action of the directional valve 300.
The controller 400 may be connected to the screw pump 200 and the reversing valve 300 by cables to control the motion. Also, the controller 400 may be disposed at the remaining side of the reservoir tank 100 except for the side where the screw pump 200 and the direction valve 300 are disposed, and be combined with the reservoir tank 100.
Fig. 9 is a graph showing the flow rate and the total efficiency of a screw pump according to the cooling module of the present invention compared with a conventional centrifugal pump. Here, the output of the screw pump according to the present invention is the same as that of the conventional centrifugal pump. As shown in the figure, it is understood that the overall efficiency of the screw pump is significantly improved compared to the centrifugal pump at the same discharge flow rate at various discharge pressures. And, the overall efficiency is shown to be excellent at a particular discharge pressure and flow rate of about 40% and higher. Further, it is found that the screw pump hardly decreases the total efficiency after about 10L/min even when the discharge flow rate is increased, and on the contrary, the conventional centrifugal pump remarkably decreases the total efficiency in a range of a specific pressure and a specific flow rate or more.
As described above, in the present invention, the total efficiency is almost unchanged with respect to the change of various discharge pressures and discharge flow rates, and the total efficiency is also significantly higher than that of a centrifugal pump, and therefore, compared with the prior art having a plurality of centrifugal pumps in a cooling water system, the present invention has an advantage in that even if only one screw pump is used, the same performance as in the past is ensured, and the efficiency is further improved. Especially under the condition of relatively high pressure and high flow rate, better effect can be obtained. Therefore, the present invention has the advantage that the cooling module has a simple structure and can reduce the number of components and simplify packaging. In addition, the inner space of the liquid storage tank is an undivided space, so that the temperature of the cooling water does not need to be distinguished, and the cooling system can be simplified.
Fig. 10 to 12 are an exploded perspective view and a sectional view illustrating a screw pump in a cooling module according to an embodiment of the present invention.
As shown, the screw pump 200 may be configured to include a motor portion 201 and a pump portion 202, and the pump portion 202 may include a driving screw 230 connected to the motor portion 201 to be driven and a driven screw 240 rotating in mesh therewith. Here, the number of the passive screws 240 may be 1, but a plurality of them may be provided as shown in the figure. The drive screw 230 may have a spiral blade 231 formed in the axial direction, and the blade 231 may be a single-spiral blade formed in one row, may have two or more rows, and may have 4 rows of spiral blades as shown in the drawing. Therefore, it is possible to obtain a sufficient discharge pressure and flow rate as required without greatly increasing the size of the screw pump.
The present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the scope of the present invention claimed in the claims.
