[0025] Example:
[0026] As attached Figure 1 In this embodiment, a monitor 100 includes: a substrate 130, a rear shell 140 and a plurality of electronic components 150, the substrate 130 and the rear shell 140 enclose a first cavity, and the electronic components 150 are accommodated in the first cavity; the substrate 130 is provided with a plurality of heat dissipation ports 1311 corresponding to the electronic components 150, the rear shell 140 is provided with heat dissipation holes, the rear shell 140 includes a metal back cover 141, and the first cavity is connected to the outside through the heat dissipation holes and the heat dissipation ports 1311;
[0027] The electronic component 150 includes a first main board 151 and a second main board 152 fixed on the substrate 130 . A heat dissipation channel is formed between the first main board 151 and the heat dissipation opening 1311 . The heat generating area of the second main board 152 is attached to the back cover 141 .
[0028] Specifically, in this embodiment, as shown in the attached Figure 1 and 4 The substrate 130 is in a groove shape, and the groove-shaped substrate 130 provides a larger space for the first cavity, thereby providing a larger space for the electronic components 150 in the first cavity, so that the spacing between multiple electronic components 150 is increased, which is beneficial to the heat dissipation of the electronic components 150. In this embodiment, preferably, the heat dissipation port 1311 is directly opposite to the orthographic projection of the electronic component 150 and the area is smaller than the orthographic projection area of the electronic component 150. Each heat dissipation port 1311 is rectangular. In other embodiments, the heat dissipation port 1311 can also be a heat dissipation mesh. The heat dissipation port 1311 is not limited in shape, number and size, as long as it can provide a channel for the electronic component 150 to dissipate heat.
[0029] As attached Figures 1 to 4In this embodiment, the back cover 141 is arranged opposite to the substrate 130, and a heat dissipation channel is formed between the first main board 151 and the heat dissipation port 1311. The heat generated by the first main board 151 when working will leave the first cavity through the heat dissipation port 1311. The second main board 152 is attached to the back cover 141, and the heat generated by the second main board 152 when working will be transferred to the outside through the metal back cover 141. This can avoid using fans or multiple radiators 1513 for heat dissipation when there are multiple main boards inside the monitor 100, which takes up space; on the other hand, because the back cover 141 is arranged opposite to the substrate 130, the first main board 151 dissipates heat through the heat dissipation port 1311 of the substrate 130, and the second main board 152 dissipates heat through the back cover 141, so the heat dissipation directions of the first main board 151 and the second main board 152 are opposite, which avoids the heat dissipation directions of the first main board 151 and the second main board 152 being opposite, resulting in the heat generated by the first main board 151 and the second main board 152 affecting each other. Preferably, the surface of the back cover 141 is serrated, which can increase the heat dissipation area and speed up the heat dissipation speed. In other embodiments, the heat dissipation method of the first mainboard 151 is not limited to allowing the heat generated by the first mainboard 151 to leave the first cavity through the heat dissipation port 1311, but can also be achieved by attaching a heat conductor 160 to the heating element of the first mainboard 151, and the heat conductor 160 transfers the heat to the substrate 130, and then the substrate 130 transfers the heat to the outside of the first cavity.
[0030] Furthermore, as attached Figure 1 The monitor 100 also includes a screen 111 assembly 110 and a front shell 120. The front shell 120 has an opening that can be embedded with a substrate 130. The screen 111 assembly 110, the front shell 120 and the substrate 130 are enclosed to form a second cavity. At least one row of heat dissipation holes of the front shell 120 is provided on the front shell 120. The second cavity is connected to the outside through the heat dissipation holes of the front shell 120.
[0031] The screen 111 assembly 110 includes a screen 111 and a screen 111 bracket. The screen 111 bracket is fixed on the screen 111 and connected to the second cavity. The screen 111 bracket is made of metal.
[0032] Specifically, the screen 111 in this embodiment is a large-sized LCD screen, which generates a large amount of heat. Therefore, this embodiment provides two structures to reduce the temperature of the LCD screen. On the one hand, when the screen 111 generates heat, the temperature of the air in the second cavity rises. Two rows of heat dissipation holes of the front shell 120 are provided on the upper side of the front shell 120. The hot air rises and passes through the heat dissipation holes of the front shell 120 to the outside. The outside air enters the second cavity, which increases the heat dissipation efficiency of the screen 111. On the other hand, the screen 111 bracket is made of aluminum material and is provided with multiple through holes, and is tightly attached to the screen 111 that needs to dissipate heat. The aluminum material has good thermal conductivity and high heat exchange efficiency with the air, which can accelerate the reduction of the temperature of the screen 111.
[0033] In this embodiment, as shown in the attached Figure 1 and 3 The opening of the embedded substrate 130 is located in the center of the front shell 120, and the edge where the opening is connected to the substrate 130 is extended and gathered, so that the edge where the opening is connected to the substrate 130 is in close contact, ensuring the sealing of the edge, making the monitor 100 more stable, and preventing the heat generated by each electronic component 150 from entering the outside from the edge during use to reduce the heat dissipation efficiency. Preferably, the surface of the substrate 130 facing the screen 111 assembly 110 also has a cylindrical protrusion 1312, and the surface of the screen 111 bracket facing the substrate 130 has a corresponding assembly rack. After the substrate 130 is embedded in the opening, the cylindrical protrusion 1312 is inserted into the corresponding assembly rack, so that the substrate 130 is fixedly connected to the screen 111 bracket. This assembly method only uses the substrate 130 and the screen 111 bracket on the screen 111 assembly 110, and the screen 111 assembly 110, the front shell 120 and the substrate 130 can be assembled together, which is convenient for the disassembly and installation of the monitor 100. In other embodiments, the screen 111 assembly 110, the front shell 120 and the substrate 130 may also be connected in a variety of detachable ways such as threaded connection and snap connection.
[0034] Furthermore, if Figure 3 and 4 The substrate 130 includes a base 131 and a bottom plate 132 connected to the base 131 . The first main board 151 includes a first port 1512 connected to the bottom plate 132 . The second main board 152 includes a second port 1522 connected to the bottom plate 132 .
[0035] Specifically, in this embodiment, the first main board 151 and the second main board 152 are arranged in parallel and connected to the base plate 132. The base plate 132 is also provided with interfaces of other electronic components 150 in the area away from the first port 1512 and the second port 1522. The type, number and distribution of the interfaces can be easily designed by technicians in this field according to actual conditions and other requirements, and will not be described in detail here.
[0036] Furthermore, if Figure 1 and 3 The first mainboard 151 further includes a first chip 1511 and a heat sink 1513 connected to the first chip 1511 , and the first chip 1511 and the heat sink 1513 face the heat dissipation channel.
[0037] Specifically, in this embodiment, one end of the heat sink 1513 is fixed on the first main board 151, wherein the first chip 1511 is closely attached to the heat sink 1513. The other end of the heat sink 1513 is a heat sink fin, and the heat sink fin is close to the heat sink 1311 corresponding to the first main board 151. The first chip 1511 generates heat when working, and the generated heat is transferred to the heat sink 1513, and then transferred to the nearby air through the heat sink fins of the heat sink 1513, so that the nearby air is heated, and the heat sink 1311 is connected with the second cavity, and the heated air enters the second cavity through the heat sink 1311, and then is transferred to the outside through the front cover heat sink 1311 on the front cover, so that the first main board 151 completes heat dissipation and the temperature is reduced. In other embodiments, the radiator 1513 may also be a smaller air-cooled radiator 1513 or a water-cooled radiator 1513, and the connection between the first chip 1511 and the radiator 1513 may also be coated with thermally conductive materials such as thermal grease and thermally conductive silicone mud, so that the first chip 1511 is in full contact with the radiator 1513, which is beneficial to heat dissipation.
[0038] Furthermore, if Figure 1 and 3 The second main board 152 includes a second chip, which is a heat generating area. The second chip is connected to the back cover 141 , and a heat conductor 160 is provided at the joint between the second chip and the back cover 141 .
[0039] Specifically, in this embodiment, the joint of the back cover 141 and the second chip is provided with a protrusion 1312, and the joint of the second chip and the protrusion 1312 is provided with a heat conductor 160, and the protrusion 1312 prevents a gap from appearing at the joint of the second chip and the back cover 141, thereby increasing the effective heat dissipation area of the second chip, and at the same time, a certain distance is kept between the second main board 152 and the back cover 141, thereby preventing the heat transferred from the second chip to the back cover 141 from affecting the second main board 152. The heat conductor 160 is also used to fill the gap between the second chip and the protrusion 1312, and timely conduct heat dissipation for the heat generated by the second chip when it is working.
[0040] Furthermore, if Figure 1~2 The bottom plate 132 is provided with first heat dissipation holes 1321 corresponding to the first main board 151 , and the bottom plate 132 is also provided with second heat dissipation holes 1322 corresponding to the second main board 152 .
[0041] Specifically, in this embodiment, the first heat dissipation holes 1321 and the second heat dissipation holes 1322 respectively corresponding to the first main board 151 and the second main board 152 are arranged on the bottom plate, which can also exchange the heat generated by the first main board 151 and the second main board 152 with the outside. It should be known that as long as the corresponding heat dissipation holes are arranged near the rear shell and the base plate of the monitor near the first main board 151 and the second main board 152, the hot air near the first main board 151 and the second main board 152 can be transferred to the outside.
[0042] Furthermore, if Figures 1 to 3 The electronic component 150 also includes a battery assembly 153, which includes a fixing frame 1531 and a battery 1532 fixed in the fixing frame 1531. One side of the fixing frame 1531 is fixedly connected to the substrate 130, and the other side opposite to the fixing frame 1531 is attached to the back cover 141. A heat conductor 160 is provided at the attachment point between the fixing frame 1531 and the back cover 141.
[0043] In this embodiment, the battery assembly 153 is close to the top plate of the substrate 130 in the vertical direction, close to one side of the rear shell 140 in the horizontal direction, and is closely attached to the rear cover 141. The portion of the rear cover 141 close to the fixing frame 1531 forms a convex body inward, and the convex body is closely attached to the battery assembly 153. The fixing frame 1531 is made of metal material that is easy to dissipate heat. The heat of the battery 1532 is first transferred to the fixing frame 1531 made of metal material. The fixing frame 1531 is coated with a heat conductor 160. The heat conductor 160 makes the fixing frame 1531 fit closely to the rear cover 141, and the heat is transferred to the outside through the rear cover 141. In other embodiments, the position of the battery assembly can be anywhere in the first cavity, as long as it is ensured that it does not interfere with the heat generated by other electronic components.
[0044] Furthermore, if Figure 1 The electronic component 150 further includes a converter 154 , which is fixedly connected to the protrusion 1312 , and a third heat dissipation hole 1421 is formed in the rear shell 140 near the converter 154 .
[0045] In this embodiment, the converter 154 is an AC to DC converter. The converter 154 is close to a side edge of the rear shell 140 away from the battery assembly 153 in the horizontal direction, and a row of third heat dissipation holes 1421 are provided on the side edge, so that the converter 154 can keep a distance from the battery assembly 153, and avoid the heat emitted by the converter 154 and the battery assembly 153 when working to affect each other. At the same time, the heat of the battery assembly 153 is transferred to the outside through the rear cover 141, and the heat of the converter 154 is transferred to the outside through the third heat dissipation holes 1421, so that the heat dissipation channels of multiple electronic components 150 are different, which speeds up the heat dissipation efficiency.
[0046] In other embodiments, electronic components 150 such as the battery assembly 153, the converter 154, the first main board 151 and the second main board 152 may be located at other positions different from those in the present embodiment, as long as the above-mentioned electronic components 150 can be fixed in the first cavity, a certain distance is maintained between each electronic component 150, and the heat can be dissipated through multiple heat dissipation locations such as the heat dissipation port 1311 of the substrate 130, the heat dissipation holes of the rear shell 140 and the rear cover 141.
[0047] Furthermore, the heat conductor 160 is thermally conductive silicone grease.
[0048] In this embodiment, if Figure 1 and 3 As shown, preferably, the thermal grease is thermal grease mud, which is coated at the connection between the second chip and the protrusion 1312 of the back cover 141; the thermal grease mud is coated at the connection between the battery assembly 153 and the protrusion of the back cover 141. Thermal grease mud is a thermal grease with high viscosity, which can change its shape as required, and the thermal grease mud will not cross-link and solidify. When the electronic component 150 needs to be replaced during the assembly process, the thermal grease mud is easy to operate. Thermal grease mud can fill the gap between the heating area of the electronic component 150 and the heat dissipation element, so that the heat is quickly exported to the heat dissipation element, thereby accelerating the heat dissipation efficiency. In other embodiments, silicon-based thermal conductors in different states can also be used, such as silicon wafers and silica gel, which also have high thermal conductivity.
[0049] Furthermore, the substrate 130 is made of metal.
[0050] Preferably, in this embodiment, the substrate 130 is an aluminum substrate 130 with light weight, good heat dissipation performance and low assembly cost. In other embodiments, the substrate 130 can also be other metal materials with good heat dissipation performance, such as a copper substrate 130 and an iron substrate 130.
[0051] Furthermore, if Figure 4 As shown, the substrate 130 is further provided with protrusions 1312 evenly distributed along the heat dissipation openings 1311 .
[0052] Preferably, if Figures 1 to 4As shown, four protrusions 1312 are arranged beside the four ends of each rectangular heat dissipation opening 1311. The protrusions 1312 are cylindrical and perpendicular to the bottom surface of the groove of the substrate 130. The other ends of the protrusions 1312 are fixedly connected to the four ends of the electronic component 150. The protrusions 1312 are used to fix the electronic component 150 between the rear shell 140 and the substrate 130, so that the electronic component 150 is stably fixed in the first cavity; on the other hand, the protrusions 1312 have a certain height, so that there is a distance between the electronic component 150 and the substrate 130, which is conducive to the heat of the electronic component 150 passing through the heat dissipation opening 1311. It should be known that the protrusions 1312 are only a structure for fixing and connecting the electronic component 150 and keeping a distance between the electronic component 150 and the substrate 130. In other embodiments, the protrusions 1312 can be brackets with a certain height, and the connection between the protrusions 1312 and the substrate 130 can also be a variety of connection methods such as threaded connection.
[0053] In this embodiment, the fixing frame 1531 of the battery assembly 153 is fixedly connected to the substrate 130 through the protrusion 1312. The protrusion can make the battery assembly 153 fit closely with the back cover 141, reduce the gap, increase the effective contact area, and facilitate heat dissipation. The converter 154 is also fixedly connected to the substrate 130 through the protrusion 1312. The height of the protrusion 1312 connected to the converter 154 is lower than the height of the protrusion 1312 connected to the battery assembly 153. This is because the multiple electronic components 150 other than the converter 154 use the substrate 130 and the back cover 141 for heat dissipation respectively. Keeping a distance between the converter 154 and the substrate 130 and the back cover 141 can prevent the heat transferred to the substrate 130 and the back cover 141 from affecting the converter 154.
[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
