Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown, a water-cooled heat dissipation device can drive a magnetic pump through magnetic transmission principle, without the need for an additional power source. The structure includes a cold head 8, a radiator 1, a cooling fan 6, and a magnetic pump 4. The radiator 1 includes a radiator frame 11, a first circulation pipe 12, and a second circulation pipe 13. The first circulation pipe 12 and the second circulation pipe 13 are distributed and installed on the radiator frame 11, and the radiator frame 11 has mounting holes 15. The cooling fan 6 includes a fan blade holder 61, on which a first magnet 5 is installed. The cooling fan 6 is installed at the bottom of the mounting hole 15, and the first magnet 5 is inserted into the mounting hole 15. The magnetic pump 4 includes an inlet end 41, an outlet end 42, and a blade... Impeller 46 is embedded in mounting hole 15 and close to first magnet 5; impeller 46 includes multiple moving blades 462, each moving blade 462 is equipped with a second magnet 461; water inlet 41 is connected to one end of second circulation pipe 13, and the other end of second circulation pipe 13 is connected to one end of cold head 8; water outlet 42 is connected to one end of first circulation pipe 12, and the other end of first circulation pipe 12 is connected to the other end of cold head 8; first magnet 5 and second magnet 461 are of the same polarity.

[0029] Since the first magnet 5 and the second magnet 461 are of the same polarity, they repel each other. The repulsive force generated between the first magnet 5 and the second magnet 461 can drive the blade to rotate.

[0030] The refrigerant flowing inside the radiator can be water-based. Water has a large heat capacity and can absorb and dissipate a large amount of heat.

[0031] A magnetic pump drives the water flow in the radiator, which can quickly absorb heat and transfer it, thus achieving rapid cooling.

[0032] It should be noted that the fan seat is usually a structure for mounting multiple fan blades. It is installed on the rotating shaft of the fan. It can be understood that when the cooling fan is powered on, the fan seat drives the fan blades to rotate to blow air, and at the same time, the first magnet 5 installed thereon rotates.

[0033] As shown in Figure 1 and 2 , a hollow area is formed in the cold row frame, and the hollow area forms a mounting hole 15. The mounting hole can make the magnetic pump embeddedly installed on the cold row, which can effectively reduce the height of the magnetic pump protruding from the cold row, and also reduce the vertical space occupied by the magnetic pump installation.

[0034] It should be noted that the first magnet 5 is inserted into the mounting hole 15 from the bottom of the cold row. When the magnetic pump is installed in the mounting hole, the bottom of the magnetic pump can be attached to the first magnet or form a gap with the first magnet. It is beneficial to the first magnet to provide sufficient magnetic force to the magnetic pump.

[0035] The cold head is used to cool the water cooling liquid flowing through the cold row. The cold head is a kind of cooling and cooling equipment.

[0036] As shown in Figure 2 , the first magnet 5 is installed on the hub of the fan seat 61.

[0037] The working mode of the utility model:

[0038] The magnetic pump 4, the cooling fan 6 and the first magnet 5 are installed in the mounting hole 15. The cooling fan 6 works, the fan seat 61 rotates, the air around the cold row 1 flows, the heat carried by the air exchanges with the first circulating pipe 12 and the second circulating pipe 13 on the cold row, the first circulating pipe 12 and the second circulating pipe 13 absorb the heat of the air, and the first magnet 5 and the second magnet 461 on the multiple moving blades 462 of the magnetic pump repel each other, so as to drive the multiple moving blades 462 to rotate, and then the magnetic pump pumps the water cooling liquid in the second circulating pipe 13 to the first circulating pipe 12, and the water cooling liquid in the first circulating pipe 12 is pumped into the second circulating pipe 13 by the magnetic pump 4. In this way, the circulation is realized, and the continuous cooling is realized.

[0039] It should be noted that the magnetic pump, the first circulating pipe, the second circulating pipe and the cold head constitute a closed water cooling liquid circulation flow structure. The water cooling liquid flowing through the first circulating pipe and the second circulating pipe absorbs the heat in the air, realizes the heat absorption of the air around the cold row, and the flowing water cooling liquid can avoid the continuous temperature rise, and timely pushes away the water cooling night after heat absorption, so as to realize the rapid cooling of the air around the cold row.

[0040] In order to view the water level in the cold row, a third circulating pipe 14 and a water level observation window 2 are further included. The water level observation window 2 is installed on the cold row frame, and one end of the water level observation window 2 is connected with the second circulating pipe 13, and the other end is connected with the water inlet end 41 through the third circulating pipe 14.

[0041] It can be understood that the water level observation window is a transparent structure. The water level of the water cooling liquid can be observed in real time. When the observation finds that the water level is lower than the set water level, the water cooling liquid can be added or replaced in time.

[0042] In order to know the amount of water cooling liquid more quickly, a water level line 3 is further included, and the water level line 3 is arranged on the water level observation window 2. The amount of water cooling liquid can be known quickly by observing the water level line 3 on the water level observation window.

[0043] In some embodiments of the present disclosure, an exhaust valve 16 is further included. The exhaust valve 16 is arranged on the water level observation window 2. The gas in the cold row can be discharged by opening the exhaust valve; and the water level observation window is sealed by closing the exhaust valve, so that water leakage does not occur.

[0044] It should be noted that when the cold row is used for the first time or maintained, the internal air can be discharged through the exhaust valve to ensure the normal circulation of the water cooling liquid.

[0045] In some embodiments of the present disclosure, a mounting structure of the magnetic pump is given, and an elastic plug 10 is further included. As shown in Figure 3 The magnetic pump 4 includes a bottom plate 43, and at least two limiting holes 44 are arranged on the bottom plate 43 and distributed close to the edge. An elastic plug 10 is arranged on the inner side of the mounting hole 15 and corresponds to the limiting hole 44; wherein the elastic plug 10 is elastically plugged with the limiting hole 44.

[0046] The elastic plug 10 is inserted into the limiting hole 44 to generate extrusion elastic deformation, and the elastic plug 10 generates a supporting force to the inner side of the hole in the limiting hole, so that the elastic plug is fixed in the limiting hole, and the magnetic pump is fixedly installed in the mounting hole 15.

[0047] The number of limiting holes 44 distributed circumferentially on the bottom plate 43 can be 2, 3, 4, 5 or 6, etc. Of course, the number of limiting holes can not be limited to this, and the appropriate number of limiting holes can be selected according to the needs.

[0048] It should be noted that each limiting hole corresponds to an elastic plug.

[0049] In order to facilitate the identification of the position of the limiting hole at the bottom of the bottom plate, a marking layer 45 is further included. As shown in Figure 3 The top surface of the bottom plate 43 is provided with the marking layer 45 corresponding to the limiting hole 44.

[0050] The identification layer can identify the color, which can be red, green, yellow, orange, etc. Each identification layer corresponds to a limiting hole 44 on the bottom of the bottom plate 43. Through the identification layer, the position of the limiting hole can be quickly known. When installing, each identification layer on the top surface of the bottom plate 43 corresponds to the plurality of elastic inserts in the mounting hole one by one, so that the magnetic pump can be moved downward along the mounting hole, so that the elastic inserts are inserted into the limiting holes correspondingly, so that the elastic inserts are elastically deformed in the limiting holes, and the elastic inserts and the inner side of the limiting hole generate a supporting force, so that the elastic inserts are fixedly inserted into the limiting holes, and then the magnetic pump is fixedly installed in the mounting hole.

[0051] In some embodiments of the present disclosure, the elastic insert 10 includes an elastic plate 101 and a base plate 102, as shown in Figure 3 and 4 The one end of the base plate 102 is installed on the inner side of the mounting hole 15, and the other end is installed with the elastic plate 101, and the top of the elastic plate 101 is bent.

[0052] As shown in Figure 4 , a structure of the bent elastic plate is given. The elastic plate 101 includes a vertical segment and an inclined segment, and the vertical segment and the inclined segment are connected by a circular arc.

[0054] It can be understood that the maximum interval between the vertical segment and the inclined segment is greater than the hole diameter of the limiting hole.

[0055] In use, the elastic insert 10 is inserted into the limiting hole 44, that is, the bent connection between the vertical segment and the inclined segment is first inserted into the limiting hole, and then the vertical segment and the inclined segment are inserted into the limiting hole. The inclined segment is inserted into the limiting hole while being pressed by the limiting hole to produce elastic deformation, so that the inclined segment has a reverse elastic force on the limiting hole. Under the elastic force of the inclined segment, the vertical segment and the inclined segment are tightly attached to the side surface of the limiting hole, so that the elastic insert is fixedly inserted into the limiting hole.
