The invention discloses an external radiator suitable for a notebook computer, which comprises a shell and a fan, wherein the shell is hollow, the fan is arranged in the shell, and the upper bottom and the lower bottom of the shell are provided with air holes through which air can pass, and the external radiator is characterized in that: the water storage tank is arranged in the shell, and the surface of the inner part of the upper bottom of the shell is tightly attached with water absorption cotton which is immersed into the water storage tank at the periphery. The notebook computer is cooled by the cooling effect generated by blowing the wet absorbent cotton through the fan.
Description
Technical Field
The invention relates to the field of notebook computer radiators, in particular to an external radiator suitable for a notebook computer.
Background
Compared with desktop computers, notebook computers are small in size and popular with most people. The external notebook computer radiator has small volume, compact arrangement of parts, smaller cooling fan and vent and insufficient cooling function, easily causes heat accumulation in the computer body, causes high temperature in the computer body and damage, and is suitable for transportation.
The core structure of the existing notebook external radiator is only a fan which can accelerate air circulation, and the flow of air can not generate a cooling effect. The heat dissipation principle is as follows: hot air is discharged by the air flow, and instead of the ambient air having a lower temperature, heat is transferred from the body having a higher temperature to the air having a lower temperature.
The invention relates to a novel radiator based on a principle of combining evaporation heat absorption and air flow, which is based on the principle that a fan blows towards a dry thermometer to prevent a thermometer pointer from descending and blows towards a wet thermometer to cause a cooling effect.
Disclosure of Invention
Aiming at the defects of the prior art, the invention discloses an external radiator suitable for a notebook computer.
The invention relates to an external radiator suitable for a notebook computer, which adopts the technical scheme that the external radiator comprises a shell and a fan, wherein the shell is hollow, the fan is arranged in the shell, and the upper bottom and the lower bottom of the shell are provided with air holes through which air can pass, so that the external radiator is an improvement of the external radiator suitable for the notebook computer, and is different from the external radiator in that: the water storage tank is arranged in the shell, and the surface of the inner part of the upper bottom of the shell is tightly attached with water absorption cotton which is immersed into the water storage tank at the periphery.
In the structure, the wet absorbent cotton is tightly attached to the inner part of the upper bottom of the external radiator shell suitable for the notebook computer, and is evaporated in the air flowing process, so that the upper bottom in contact with the bottom of the notebook computer body can be cooled firstly, and then the air subjected to evaporation and cooling in the radiator flows to the computer to replace the hot air at the bottom of the notebook computer body.
In order to increase the contact area between the flowing air and the absorbent cotton and avoid the flowing air from directly flowing out of the air holes at the upper bottom without passing through the surface of the absorbent cotton, a wind shield is arranged between the fan and the absorbent cotton, and a space is reserved between the wind shield and the fan as well as between the wind shield and the absorbent cotton.
In order to discharge the cooler air along the bottom of the computer and not reduce the contact area between the computer and the upper bottom of the shell, a plurality of grooves which are uniformly arranged and are communicated with the periphery of the side face of the shell from the air holes are arranged on the outer surface of the upper bottom of the shell.
In order not to influence the air flow, the corresponding positions of the water absorption cotton and the air holes at the upper bottom of the shell are provided with air holes, and the outer part of the lower bottom of the shell is provided with feet.
The invention has the beneficial effects that:
1. in the external radiator structure suitable for the notebook computer, the wet absorbent cotton is tightly attached to the inner part of the upper bottom of the shell, the wet absorbent cotton is evaporated in the air flowing process to cool the upper bottom contacted with the bottom of the notebook computer body so as to cool the bottom surface of the notebook computer body, and the evaporated and cooled air in the radiator flows to the computer to replace the hot air at the bottom of the notebook computer body, so that the external radiator structure has a better cooling effect compared with the external air directly.
Drawings
FIG. 1 is a schematic cross-sectional view of an external heat sink for a notebook computer according to the present invention;
fig. 2 is a schematic diagram illustrating components of an external heat sink for a notebook computer according to the present invention.
And (3) identifying the figure number: 1. the device comprises a shell, 2, a fan, 3, air holes, 4, a water storage tank, 5, absorbent cotton, 6, a wind shield, 7, a groove, 8 and feet.
Detailed Description
The present invention will be further described with reference to the following examples, but the present invention is not limited to these examples.
The invention relates to an external radiator suitable for a notebook computer, which comprises a shell 1 and a fan 2, wherein the shell 1 is hollow, the fan 2 is arranged in the shell 1, and air holes 3 capable of enabling air to pass through are formed in the upper bottom and the lower bottom of the shell 1.
Compared with the common radiator, the external radiator for the notebook computer provided by the invention has the advantages that the water storage tank 4 is arranged inside the shell 1, and the water absorption cotton 5 with the periphery immersed into the water storage tank 4 is tightly attached to the inner surface of the upper bottom of the shell 1. In the structure, the external radiator suitable for the notebook computer provided by the invention dries the absorbent cotton 5 through the fan 2 to cool the upper bottom of the shell 1, the computer in contact with the shell 1 is cooled through heat transfer, and the temperature of blown air is lower than that of external air, so that the external radiator has a better cooling effect than that of the external air directly used, as shown in fig. 1.
A wind shield 6 is arranged between a fan 2 and a water absorption cotton 5, and a gap is reserved between the wind shield 6 and the fan 2 and the water absorption cotton 5. In the above structure, the wind shield 6 can make the air driven by the fan 2 not directly go out from the air hole at the upper bottom of the casing 1, but bend around and flow from the edge to the center of the absorbent cotton 5, increasing the contact area between the flowing air and the absorbent cotton 5, as shown in fig. 1.
The outer surface of the upper bottom of the shell 1 is provided with a plurality of grooves 7 which are uniformly arranged and are communicated with the periphery of the side surface of the shell 1 from the air holes 3, so that air can be discharged along the bottom of the computer, and the contact area between the computer and the shell 1 is not occupied, as shown in figure 2.
The water absorption cotton 5 is provided with air holes 3 corresponding to the air holes 3 at the upper bottom of the shell 1, and feet 8 are arranged outside the lower bottom of the shell 1. The above structure does not obstruct the entrance and exit of gas, as shown in fig. 1 or fig. 2.
The invention relates to a use method of an external radiator suitable for a notebook computer, which comprises the following steps:
the notebook computer can achieve the heat dissipation effect by switching on the power supply of the fan and placing the notebook computer on the notebook computer, and the heat dissipation effect can be enhanced by adding a proper amount of water into the water storage tank.
