New description: [New technical field] is a heat dissipation structure of a portable electronic device. About the prior art [Prior technology] The main electronic device, its computing performance is getting better and better, so the integrated circuit components of the different operating systems (such as the central processing unit, drawing.) are also getting more and more. When the portable electronic device (10) The heat cannot be properly made easy for the user to feel that the two devices cannot be lifted up. The solution to the problem is that the portable electronic device (4) is equipped with a fan to increase the convection of the hole and the money "near wire and side ventilation" (4) The way the body flows is “bottom-in and side-out.” It is often placed on the desktop to make (4) portable electronic devices, heat dissipation: there is a problem, but it is often placed on the user's lap (4) portable ^ The vent hole on the bottom of the body is easily broadcasted and affects the heat dissipation in the body. In view of the above problems, an improved heat dissipation structure of the portable electronic device is needed to solve the above problems. '"Settings [New Content] Therefore, the present invention is in the form of a (four) electric type which includes a body and a fan. The body has two opposite first sides 3 and a second side, the first life丨 目 士The side of the younger one has an air outlet, and the second side has an inlet and a body, and has an air outlet and an air inlet. The first and second sides have at least one air passage connected to the air inlet and the air inlet. The cross-sectional area of the air inlet hole of the channel is smaller than that of the air outlet hole. The other type of the type is provided with a portable electronic device, a basin=and a right plurality of heating elements, a wind guide and a fan. The two sides are opposite to the first side and the second side, and the first side has a wind: L 'the first side has an air inlet hole. The heating elements are located in the body. The wind 7G piece is located in the heating element and the human wind Between the holes to the heating elements, the fan is located in the body and has a gas outlet port. The space configuration in the body has at least - an air flow channel is connected to the air inlet and the air inlet. As can be seen from the above, portable electronic applications are used. The "side-in and side-out" of the device and the confrontation method prevent the ventilating holes from being easily blocked. The bottom surface of the portable electronic device also has waterproof function because it does not need to be provided with ventilation holes. Furthermore, the internal unit of the portable electronic device The arrangement of the positions of the parts also makes the temperature distribution in the body more uniform, and local overheating does not occur. [Embodiment] Referring to the 1st '', a portable electronic device according to the present invention is shown. The portable electronic device i (10) can be a large-sized or small-sized notebook computer, a tablet computer, etc. The portable electronic device can be used for cutting the body 3 - the body 102 and the display portion 1G4. The display portion is on the body W2 so that the display portion 1〇4 can 2 fit on the body or with the (4) 2 (4) 2 rotation and skill. The display unit] 04 has 4 M377851 with screen 104a for displaying information' and the body i〇2 has keyboard i〇2b for input information. The portable electronic device can also be a body with a touch screen (not shown), without the need to divide the body into the body and the display portion described above. In an embodiment of the present invention, the side surface of the body or the body of the portable electronic device is provided with a vent hole, so that the thermal convection mode of the electronic device is "lateral side exit". Since all the vent holes are designed on the side of the body or the body, there is no problem that the vent holes are easily blocked. In Fig. 1, the vent holes are located on opposite sides i 〇 2b and 102c of the body 102. More specifically, when the user faces the screen 1 〇 4a, the sides 102b, 102c of the body 102 are the right and left sides of the user, respectively. 2 is a side view of the portable electronic device of FIG. 1 showing the side 102c. The side surface l〇2c is provided with two groups of air inlet holes i〇8a and i〇8b. The bottom surface 102d does not have a vent hole, so there is no need to consider whether it is easily blocked, and it has a waterproof function. Figure 3 is a side elevational view of the portable electronic device of Figure 1 showing the side 102b. The side surface i〇2b is provided with a group of air outlet holes 106. The bottom surface 102d does not have a venting opening so that there is no need to consider whether it is easily blocked or not, and it has a waterproof function. Fig. 4 is a cross-sectional view showing the A_A in Fig. 1, which is scraped, showing a cross section of the body from the air inlet hole 108a to the air outlet port 1〇6. Since the air inlet hole i〇ga and the air outlet 106 are respectively located on opposite sides of the main body 1〇2, the distance is long, and a fan 11 设置 is disposed near the air outlet 106 to increase the efficiency of heat convection. The fan 110 can be a centrifugal fan with an air outlet 110b aligned with the air outlet. In the present embodiment, the fan fan is located closer to the air outlet hole 1a than the air inlet hole 5a. The so-called centrifugal fan is such that the inlet port n〇c is located in the axial direction of the blade 110a and the outlet port u〇b is located in the radial direction of the blade n〇a. The direction of the arrow shown in Fig. 4 is the direction of heat convection in the body, that is, from the air inlet hole l8a to the air inlet port 110c of the fan 11〇, and then the airflow is taken from the air outlet hole 110b to the air outlet port 1 by the fan 11〇. 6. When the fan blade u〇a is rotated, forced heat convection in the direction of the arrow described above can be generated. The air flow path from the air inlet hole 1〇8a to the air inlet of the wind genus 110 needs to have a sufficient inner diameter. For the present embodiment, the inner diameter may be the distance between the thickest member 112 and the upper casing i〇3a. When dl is at least greater than 0.3 mm, it helps to maintain sufficient efficiency for thermal convection. In the body 102, the plurality of heat generating elements 112, 114, 116, 118 on the motherboard 1 〇 5 may also be arranged slightly so that the temperature distribution in the body 1 〇 2 is more evenly distributed without local overheating. For example, the thicker member 112 of the heat generating component may be closer to the air inlet hole 1 8a (in other words, closer to the air outlet hole 106 than the air inlet hole 108a). Element 112 can be a relatively thick component such as a hard disk. In addition, the element 114 with more heat generated in the heating element can also be closer to the air inlet 108a (in other words, the distance from the air inlet 1〇8& Lu is closer to the air outlet 106), so that the lower temperature airflow can be faster. Cooling element 1H. Element 114 can be a more thermally generated component such as a graphics chip, a south bridge, a north bridge, or a central processor. In addition, the thickness of the 'heat generating elements 112, 114, 116, 118 from the air inlet holes 1 〇 8 & to the air outlet holes 106 are sequentially decreased, so that the air flow passage 13 〇 naturally forms a small tail passage, that is, the air passage passage air inlet area Less than the cross-sectional area of the air outlet, it also helps to increase the flow efficiency of the airflow. FIG. 5A is a perspective view showing a part of B-b in FIG. 1 , which shows a perspective view of the body from the air inlet hole l 8b (the orientation of FIG. 5A and FIG. 6 of the M377851 is reversed upside down). Please refer to the ΙΑ, 5A diagram 'the air inlet hole l 〇 8b to approach the battery 120. Because the battery 120 with excessive thickness will block the air inlet hole 108b, and the battery cannot change shape, another wind guiding member 丨24 is located. Between the air hole i〇8b and the battery. The air guiding element 124 has a wind guiding surface, wherein the air guiding section 124a is not parallel to the air inlet hole 108b to help the airflow smoothly enter the body, so that the air flow is guided through the surface of the heat dissipating component and the four flow direction to the back of the heat dissipating component The way around the flow. After flowing through the wind-guiding surface 124a, the airflow 1 turns to the heating element I12 before flowing to the #120, and flows toward the fan along the bottom edge of the heating element 112. After flowing through the wind-guiding surface Q4a, the airflow 2 turns to the heat-generating element I12 after contacting the battery 120 and flows toward the fan along the bottom edge of the heat-generating element 112. After the airflow 3 flows through the wind-guiding surface 12, it turns to the heating element 1丨2 and flows along the side wall of the heating element 112 in the fan direction before the battery 120 is touched. After the airflow 4 flows through the wind-guiding surface 124a, it turns to the heat-generating component and flows along the side wall of the heat-generating component 112 toward the fan after contacting the battery 120. The wind guiding member Π4 may be an antenna structure or an element thereof which can change its shape. Figure 5 is a perspective view similar to Figure 5, in which the thickness of the component m is thick. Because of the thicker thickness of component m, wind deflecting element 124 causes the airflow to be directed through the surface of the heat dissipating component and the two flow directions that flow around the back of the heat dissipating component (reducing the two flow directions from the embodiment of Figure 5A). After flowing through the air guiding section 12, the airflow 1 turns to the heating element 112 before flowing to the battery i20 and flows in the direction of the fan along the bottom edge of the heating element 112. After flowing through the air guiding section 124a, the airflow 2 is turned to the heating element 112 after contacting the battery 7 M377851 120 and flows in the direction of the fan along the bottom edge of the heating element 112. Although the above-described wind guiding member 124 is exemplified by a trapezoidal cross section, the wind guiding member may have a curved or rectangular cross section, and the shape of the cross section is not limited, and is also suitable for use as a flow guiding. Fig. 6 is a cross-sectional view taken along line C-C' in Fig. 1, and Fig. 5A or 5B shows a cross section of the body to the air outlet 106. Please refer to the figures ΙΑ, 5A, 5B, and 6 at the same time, wherein the direction of the arrow is the φ heat convection direction in the body, that is, guided from the air inlet hole 108b through the air guiding member 124 along the air guiding member 124 and the lower casing 103b. The gap flows (refer to the flow directions of the airflows 1 to 4 described above), then to the air inlet 110c of the fan 110, and the airflow is taken from the air outlet 111b to the air outlet 106 by the fan 110. When the blade 110a is rotated, forced heat convection in the direction of the arrow as described above can be generated. As is apparent from the above-described embodiments 4, 5A, 5B, and 6, the side surface 102c is provided with two groups of air inlet holes 108a and 108b, and the element design closest to the air inlet hole has a flow guiding design for increasing the flow efficiency of the air flow. In addition, the thickness of the heating element is sequentially decreased along the flow path, so that the air passage naturally forms a small mouth. The large passage of the tail also contributes to the flow efficiency of the air flow. As can be seen from the above-described embodiments of the present invention, the heat convection mode of the "side-in side-out" of the portable electronic device of the present invention makes the disadvantage that the conventional vent hole is easily blocked from occurring. The bottom surface of the portable electronic device also has a waterproof function because it does not need to be provided with a vent hole. Moreover, the arrangement of the components in the portable electronic device also makes the heat convection efficiency in the body better, the temperature distribution is more even, and local overheating does not occur.
