Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a modular heat dissipation structure and a thermal energy management component for a microcomputer. Background Art

[0002] Microcomputer refers to a type of computer that is small in size and easy to carry. Its internal electronic components are compactly arranged and composed of large-scale integrated circuits. The microcomputer system has three levels from global to local: microcomputer system, microcomputer, and microprocessor (CPU). Neither a simple microprocessor nor a simple microcomputer can work independently. Only a microcomputer system is a complete information processing system and has practical significance.

[0003] In order to facilitate maintenance and replacement, the entire cooling system is divided into multiple independent modules, each of which has its specific functions, such as heat conduction, heat dissipation, fan control, etc. This design makes maintenance and replacement easier, and minimizes the size and weight of each module so that more modules can be integrated in a limited space.

[0004] Although the computer's heat dissipation mechanism is designed to be modular to reduce space and improve space utilization, the existing microcomputer heat dissipation structure will emit a large amount of heat during use. Since most microcomputers are placed at the bottom of a cabinet when working, the computer is close to human legs and feet, and the environment is not easy to clean and easily accumulates dust, which can cause the computer's air intake filter to become clogged, resulting in heat accumulation that affects the computer's heat dissipation effect.

[0007] As a further improvement of the present technical solution, the guide portion includes an air guide box which covers the exhaust gas cover at one end and is interconnected at the other end. The connecting parts of the air guide boxes on both sides have openings, and cooling fins are arranged inside the openings. The air guide box is used to guide the hot air discharged from the exhaust port to the cooling fins so that the hot air is liquefied after passing through the cooling fins.

[0009] As a further improvement of the present technical solution, a drainage chamber and a piston chamber are sequentially arranged inside the liquid collecting box from top to bottom, and the width of the drainage chamber is larger than that of the piston chamber. Under normal circumstances, the piston plate is located in the drainage chamber so that the liquid enters the piston chamber after passing through the drainage chamber, and when the piston plate moves downward into the piston chamber, the piston plate fits against the inner wall of the piston chamber.

[0010] As a further improvement of the technical solution, a tension spring is elastically connected between the top of the piston plate and the inner wall of the drainage chamber, and a nozzle is provided inside the piston chamber, which is lower than the connection between the liquid collecting box and the air guide box in the horizontal direction.

[0013] As a further improvement of the technical solution, a rotating rod is fixedly connected to the winding disk on the leeward side close to the air inlet. Under normal conditions, the extension line of the bottom of the rotating rod intersects with the central axis of the winding disk. The top of the rotating rod is fixedly connected to a slider via a cross bar. The outside of the slider is slidably connected to a track fixedly connected to the connecting pipe.

[0040] Example 1

[0041] like Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, a modular heat dissipation structure of a microcomputer is provided, comprising a main housing 100 and an air inlet 101 opened on the back of the main housing 100, an exhaust port 102 symmetrically opened on the side wall of the main housing 100, and a heat management component is arranged inside the main housing 100, wherein the fan 140 is covered with a bracket 142 for protecting the fan 140, and a heat sink 141 is fixedly connected to the opposite side of the bracket 142, and the heat sink 141 and the fan 140 are elastically connected through a connecting spring 143. In this way, when the fan 140 is started, the fan 140 inhales air from the air inlet 101 to dissipate the heat of the heat sink 141, so that the heat generated by the electrical components is quickly transferred through the heat sink 141 and dissipated into the air, and the hot air is discharged from the exhaust ports 102 on both sides, which is the process of heat dissipation of the electrical components.

[0042] A power unit 130 is also provided on the leeward side of the air inlet 101. By pressing the lever 110 with an arc-shaped bottom provided beside the fan 140, the reset spring 111 on the top of the lever 110 is against the main housing 100, so that the lever 110 moves the fan 140 closer to the power unit 130 and drives the power unit 130 to rotate (in this process, if the power of the moving fan 140 is not enough to drive the power unit 130 to rotate, power compensation can be performed by an external motor). The power unit 130 uses the fan 140 as power to pressurize the air and liquid inside the guide unit 120, so that the air is ejected from the leeward side of the air inlet 101 to the windward side, so as to realize the backblowing of the filter in the air inlet 101, and prevent impurities from clogging the filter and affecting the air intake and the heat dissipation of electrical components. The following is a detailed description in conjunction with the following text:

[0043] First, based on the above structure, combined with Figure 4 As shown, a guide portion 120 for storing liquid is provided on the main casing 100 located above the windward side of the air inlet 101, and the guide portion 120 is connected to a piston box 124 located on the leeward side of the air inlet 101. The guide portion 120 includes an air guide box 121 that covers the exhaust port 102 at one end and is interconnected at the other end. The connecting part of the air guide boxes 121 on both sides has an opening, and a cooling fin 123 is provided inside the opening. The air guide box 121 is used for guiding the hot air discharged from the exhaust port 102 to the cooling fin 123, so that the hot air is liquefied after passing through the cooling fin 123, thereby providing a water source for suppressing impurities for backblowing in the later stage, so as to prevent the impurities cleaned during backblowing from splashing outward and affecting the surrounding air quality.

[0044] In addition, the guide part 120 also includes a liquid collecting box 122 located below the cooling plate 123 and fixedly connected to the main housing 100, the liquid collecting box 122 has a piston plate 133 inside, the top of the liquid collecting box 122 has an opening, the top of the liquid collecting box 122 is separated from the opening of the air guide box 121 (so that the liquid inside the liquid collecting box 122 can be replenished manually when there is less liquid inside), and the liquid collecting box 122 is sequentially provided with a drainage cavity and a piston cavity from top to bottom, the width of the drainage cavity is greater than the piston cavity, under normal conditions, the piston plate 133 is located in the drainage cavity, so that the liquid enters the piston cavity after passing through the drainage cavity, and when the piston plate 133 moves downward into the piston cavity, the piston plate 133 fits with the inner wall of the piston cavity. In addition, a tension spring 134 is elastically connected between the top of the piston plate 133 and the inner wall of the drainage cavity, and a nozzle is provided inside the piston cavity, and the nozzle is lower than the connection between the liquid collecting box 122 and the piston box 124 in the horizontal direction. In this way, when the hot air is liquefied into water droplets through the cooling plate 123, the water droplets enter the drainage chamber from the opening of the air guide box 121 and are stored in the piston chamber. When the piston plate 133 moves from the drainage chamber to the piston chamber, the piston plate 133 can pressurize the air and liquid inside the piston chamber to reduce the air inside the piston chamber and increase the pressure. Under the action of the piston plate 133, the gas inside the piston chamber is discharged from the piston box 124, and the liquid is sprayed out from the nozzle.

[0045] Combine the following Figure 6 As shown, after the gas is transported from the piston chamber to the piston box 124, it is backblown toward the filter on the leeward side of the air inlet 101 to separate the impurities attached to the filter from the filter. The reason is that a piston rod 170 is slidably arranged inside the piston box 124, the piston rod 170 passes through the bottom of the piston box 124, and the bottom of the piston rod 170 is connected to a connecting pipe 171 that is larger than the width of the air inlet 101, the piston rod 170 is slidably connected to the piston box 124, and a plurality of air holes are arranged on the connecting pipe 171 on the leeward side close to the air inlet 101, so that the gas can be ejected from the air holes after passing through the piston rod 170 and the connecting pipe 171 to backblow the filter in the air inlet 101, so as to blow down the impurities on the windward side of the filter, reduce the resistance of air passing through the air inlet 101, make the air circulate smoothly, and ensure the heat dissipation of the electrical components.

[0046] Return to Figure 3 and Figure 4 As shown, the power of the piston plate 133 comes from the power unit 130, so Figure 3 and Figure 4 Based on and combined with Figure 6 and Figure 8The structure of the power unit 130 is disclosed. The power unit 130 includes a winding disc 131 around which a traction rope 132 is wound for multiple turns. The winding disc 131 is rotatably connected to a bracket 142. The winding disc 131 and the fan 140 are engaged with a latch. One end of the traction rope 132 passes through the main housing 100 and is fixedly connected to the bottom of the piston plate 133. In this way, in combination with Fig. 9 As shown, when the lever 110 moves downward, the lever 110 drives the fan 140 to move toward the winding disk 131, and the fan 140 is connected to the winding disk 131 with a pin. At this time, the fan 140 drives the winding disk 131 to rotate, and the winding disk 131 rotates to wind the traction rope 132, so that the winding disk 131 pulls the piston plate 133 downward, and the tension spring 134 is stretched. When the fan 140 is reset, the tension spring 134 elastically resets and stretches the piston plate 133 to move upward, so that the traction rope 132 pulls the winding disk 131 to reverse and reset.

[0047] Furthermore, it can be understood by those skilled in the art that in the present invention, the winding disc 131 and the air deflector 150 can be directly connected, or connected to the winding disc 131 and the air deflector 150 through a reduction gear set. The connection relationship belongs to the prior art and will not be described in detail here. Secondly, the function of the reduction gear set is to allow the winding disc 131 to rotate at a low speed to prevent the winding disc 131 from rotating at an angle that is too large, and the piston plate 133 cannot match the travel of the piston plate 133, causing the traction rope 132 to be tight or even broken.

[0048] Example 2

[0049] Furthermore, in order to improve the cleaning effect of the filter screen in the air inlet 101, Figure 5 and Figure 8 As shown, the embodiment 2 of the present invention is shown, a rotating rod 160 is fixedly connected to the winding disk 131 on the leeward side of the air inlet 101, under normal conditions, the extension line of the bottom of the rotating rod 160 intersects with the central axis of the winding disk 131, and the top of the rotating rod 160 is fixedly connected to a slider 161 through a cross bar, and the slider 161 is externally slidably connected to a track 172 fixedly connected to a connecting pipe 171. When the rotating rod 160 rotates, the slider 161 lowers the height of the connecting pipe 171 and covers the air inlet 101 with the blown air, so that the connecting pipe 171 gradually moves downward to back-blow the impurities attached to the windward side of the filter screen, thereby improving the cleaning effect of the filter screen. When the winding disk 131 rotates in the opposite direction, the slider 161 moves the track 172 to rotate the connecting pipe 171 in the same direction.

[0050] Example 3

[0051] While improving the cleaning effect of the filter screen in the air inlet 101, the impurities after backblowing will pollute the air. In order to prevent the impurities after backblowing from polluting the surrounding air, therefore, combined with Fig.11As shown, embodiment 3 of the present invention is shown, which is specifically as follows:

[0052] A flow guide hood 150 and a collection hood 151 are arranged in sequence from top to bottom at the bottom of the liquid collecting box 122. There is a gap between the flow guide hood 150 and the collection hood 151 to allow external air to enter. The flow guide hood 150 cooperates with the collection hood 151 to completely cover the air inlet 101. The flow guide hood 150 has a liquid channel inside, and the flow guide hood 150 is connected to the piston cavity inside the liquid collecting box 122. The flow guide hood 150 and the collection hood 151 are both arc-shaped. When the filter is backblown, the liquid channel uses liquid to flow out of the liquid channel to absorb impurities that have escaped from the filter, so as to limit the backblown impurities, thereby preventing the impurities after the backblowing from splashing outward and affecting the surrounding environment.

[0053] The liquid absorbs the impurities after backblowing and then flows into the collecting hood 151, and is discharged into the external recovery tank through the collecting hood 151. The guide hood 150 has a protective effect under normal conditions. When the impurities on the filter are backblown, the guide hood 150 limits the backblown impurities and guides them to the outlet of the liquid channel. The gap between the guide hood 150 and the collecting hood 151 is intercepted by the flowing liquid, which increases the weight of the impurities after they come into contact with the liquid, thereby limiting the impurities from floating in the air.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
