Description

Technical Field

[0001] This utility model relates to the field of computer cooling technology, specifically a computer cooling device. Background Technology

[0002] Computer cooling devices are used to reduce the temperature of computer hardware. They are devices or instruments that transfer heat generated by machinery or other equipment during operation to avoid affecting its normal operation, so as to ensure that the computer remains stable and efficient when running under high load.

[0003] Chinese patent CN218481816U discloses a computer cooling device, comprising a computer body and a heat dissipation mechanism. The heat dissipation mechanism is located inside the computer body, a dustproof mechanism is located at the front end of the computer body, and an anti-slip pad is located at the bottom end of the computer body. When using the heat dissipation mechanism, the device is connected to an external power source. When the computer host temperature is high, a temperature sensor inside the computer host monitors the internal temperature and transmits the data to a programmable controller. The programmable controller then controls a second cooling fan to rotate, promoting airflow within the computer host and facilitating heat dissipation. When the temperature sensor detects a further increase in temperature, the programmable controller controls a first cooling fan to circulate air, which passes through a liquid condenser box, lowering the air temperature and further cooling the internal components of the computer host, thus achieving the goal of cooling the computer body.

[0004] The aforementioned device has the effect of cooling the inside of the computer host, but there are many cooling dead zones inside the computer host, which prevents air from circulating and affects the heat dissipation effect of the computer host. At the same time, traditional cooling cannot control the temperature of the cooling airflow according to the usage of the computer host, resulting in low computer working efficiency. Therefore, there is a need to provide a computer cooling device. Utility Model Content

[0005] The purpose of this invention is to provide a computer cooling device to solve the problem that existing devices cannot penetrate deep into the computer host when cooling the computer host, and the temperature of the heat dissipation airflow is uniform, resulting in low computer cooling efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a computer cooling device, comprising a fixed plate, wherein a flow guiding mechanism is provided on one side of the fixed plate; the flow guiding mechanism includes a first fixed base, the first fixed base being fixedly installed on one side of the fixed plate, and a fan being fixedly installed on the first fixed base, and three heat dissipation outer grilles being fixedly installed at the rear of the first fixed base, each of the three heat dissipation outer grilles having a plurality of limiting grooves, each of the plurality of limiting grooves having a limiting seat slidably installed in the plurality of limiting grooves, and a heat dissipation inner grille being fixedly installed between the plurality of limiting seats, a top plate being fixedly installed at one end of the heat dissipation inner grille, and a pull ring being fixedly installed on the front side of the top plate.

[0007] Preferably, both the outer heat dissipation grille and the inner heat dissipation grille are composed of several horizontal plates, and the outer heat dissipation grille is in close contact with the inner heat dissipation grille.

[0008] Preferably, the rear part of the first base has three small holes, and the three heat dissipation grilles are respectively adapted to the three small holes.

[0009] Preferably, a purification mechanism is provided on the other side of the fixed plate. The purification mechanism includes a second fixed base, which is fixedly installed on the other side of the fixed plate. A first filter screen is fixedly installed on one side of the second fixed base, and a baffle is fixedly installed on the other side of the second fixed base. A cooling copper mesh is fixedly installed on the rear part of the baffle, and a second filter screen is fixedly installed on one end of the baffle. Guide rails are fixedly installed on both the upper and lower sides of the second fixed base, and a partition is slidably installed between the two guide rails.

[0010] Preferably, the width of the baffle is the same as the width of the partition, and a lever is fixedly installed on one side of the partition.

[0011] Preferably, the pore density of the first filter screen is greater than that of the second filter screen, and a gap is left between the cooling copper mesh and the baffle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This computer cooling device moves the inner heat dissipation grille within the outer heat dissipation grille by controlling a pull ring, extending the inner heat dissipation grille into the computer host. When in use, after the fan is turned on, airflow enters the inner and outer heat dissipation grilles from the computer host and is exhausted to the outside of the computer host by the fan. Benefiting from the extendability of the inner heat dissipation grille, the device can adapt to complex computer host circuit environments and also plays a role in guiding airflow, thereby improving the cooling effect of the computer.

When the No. 2 filter is blocked, the cooling copper mesh is closed, and the gas enters the computer host through the No. 1 filter, achieving the normal cooling effect of the computer and realizing the energy-saving effect of the cooling device.

[0021] 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.

[0022] Example 1

[0023] Combination Figures 1-5A computer cooling device includes a fixed plate 1, with a flow guiding mechanism 2 on one side of the fixed plate 1. The flow guiding mechanism 2 includes a first fixed base 201, which is fixedly installed on one side of the fixed plate 1. A fan 202 is fixedly installed on the first fixed base 201, and three heat dissipation outer grilles 203 are fixedly installed at the rear of the first fixed base 201. Each of the three heat dissipation outer grilles 203 has several limiting grooves 204. Each limiting groove 204 has a limiting seat 205 slidably installed in it. A heat dissipation inner grille 206 is fixedly installed between the limiting seats 205. A top plate 207 is fixedly installed at one end of the heat dissipation inner grille 206, and a pull ring 208 is fixedly installed on the front side of the top plate 207.

[0024] See Figure 2 and Figure 3 Furthermore, it is found that both the outer heat dissipation grille 203 and the inner heat dissipation grille 206 are composed of several horizontal plates, and the outer heat dissipation grille 203 is closely attached to the inner heat dissipation grille 206. The rear part of the first fixed base 201 is provided with three small holes, and the three outer heat dissipation grilles 203 are respectively adapted to the three small holes.

[0025] Specifically, the heat dissipation inner grille 206 and the heat dissipation outer grille 203 are slidably connected by the limiting seat 205, and the heat dissipation inner grille 206 can be positioned on the heat dissipation outer grille 203 under the action of the limiting seat 205. Then, the extension degree of the heat dissipation inner grille 206 can be controlled according to the internal circuit environment of the computer host. The extension degree of the heat dissipation inner grille 206 can be controlled externally by using the pull ring 208. When in use, when the fan 202 is rotated, the airflow will be guided to the fan 202 through the heat dissipation inner grille 206 and the heat dissipation outer grille 203. Benefiting from the heat dissipation inner grille 206 penetrating into the computer host, the cooling effect of the computer will be improved.

[0026] Example 2

[0027] Combination Figure 1 and Figure 4 A purification mechanism 3 is provided on the other side of the fixed plate 1. The purification mechanism 3 includes a second fixed base 301, which is fixedly installed on the other side of the fixed plate 1. A first filter screen 302 is fixedly installed on one side of the second fixed base 301, and a baffle 303 is fixedly installed on the other side of the second fixed base 301. A cooling copper mesh 304 is fixedly installed at the rear of the baffle 303, and a second filter screen 305 is fixedly installed at one end of the baffle 303. Guide rails 306 are fixedly installed on both the upper and lower sides of the second fixed base 301, and a partition 307 is slidably installed between the two guide rails 306.

[0028] See Figure 4Furthermore, based on Embodiment 1, the width of the baffle 303 is the same as the width of the partition 307, a lever is fixedly installed on one side of the partition 307, the filter pore density of the first filter screen 302 is greater than the density of the second filter screen 305, and a gap is left between the cooling copper mesh 304 and the baffle 303.

[0029] Specifically, by moving the partition 307, when the partition 307 moves to the second filter 305 and completely blocks the baffle 303, external gas enters the computer host only through the first filter 302. At this time, the cooling copper mesh 304 can be closed. When the partition 307 moves and completely blocks the first filter 302, external gas enters the computer host only through the second filter 305. Since the second filter 305 is narrower and the cooling copper mesh 304 is installed on one side of the baffle 303, the gas is compressed and completely passes through the cooling copper mesh 304 before entering the computer host. At this time, the temperature of the gas entering the computer host is lower, which can provide a rapid cooling effect for the computer.

[0030] In actual operation, the heat dissipation inner grille 206 and the heat dissipation outer grille 203 are slidably connected by the limiting seat 205, and the heat dissipation inner grille 206 can be positioned on the heat dissipation outer grille 203 under the action of the limiting seat 205. Then, the extension degree of the heat dissipation inner grille 206 can be controlled according to the internal circuit environment of the computer host. The extension degree of the heat dissipation inner grille 206 can be controlled externally by using the pull ring 208. When in use, when the fan 202 is rotated, the airflow will be guided to the fan 202 through the heat dissipation inner grille 206 and the heat dissipation outer grille 203. Benefiting from the heat dissipation inner grille 206 penetrating into the computer host, the cooling effect of the computer will be improved.

[0031] When the partition 307 moves to the second filter 305 and completely blocks the baffle 303, external gas enters the computer host only through the first filter 302. At this time, the cooling copper mesh 304 can be closed. When the partition 307 moves and completely blocks the first filter 302, external gas enters the computer host only through the second filter 305. Since the second filter 305 is narrower and the cooling copper mesh 304 is installed on one side of the baffle 303, the gas is compressed and completely passes through the cooling copper mesh 304 before entering the computer host. At this time, the temperature of the gas entering the computer host is lower, which can provide a rapid cooling effect for the computer.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
