技术领域 technical field
本实用新型涉及投影设备技术领域，特别涉及一种投影仪。 The utility model relates to the technical field of projection equipment, in particular to a projector.
背景技术 Background technique
为了确保投影仪的投影效果，需要确保其散热效果。 In order to ensure the projection effect of the projector, it is necessary to ensure its cooling effect.
目前，市场上的投影仪中的散热系统主要有两种： At present, there are mainly two types of heat dissipation systems in projectors on the market:
一种散热系统应用轴流风扇，如图1所示，轴流风扇102相对于投影机竖直放置，外界冷却风主要从投影机的侧面进风和出风，依次经过散热器鳍片101及轴流风扇102。但是，由于轴流风扇102的直径需满足一定尺寸，以提供足够的动力使外界冷却风流动，投影机的厚度较大；并且，受投影机外壳内安装尺寸的限制，轴流风扇102的直径不小于30mm，以满足散热要求，进一步导致了投影仪的厚度较大的情况。 A heat dissipation system using an axial flow fan, as shown in Figure 1, the axial flow fan 102 is placed vertically relative to the projector, and the external cooling air mainly enters and exits from the side of the projector, passing through the radiator fins 101 and the Axial fan 102. However, since the diameter of the axial flow fan 102 needs to meet a certain size to provide enough power to make the external cooling air flow, the thickness of the projector is relatively large; Not less than 30mm to meet heat dissipation requirements, which further leads to a larger thickness of the projector.
另一种散热系统应用涡轮风扇，如下图2所示，散热器鳍片201及涡轮风扇202在投影仪的厚度方向平行设置，这种散热结构常用于笔记本电脑里面。但是，这种散热系统的占用面积比较大，外界冷却风由外壳的侧面流入，经过散热器鳍片201及涡轮风扇202，使得散热的风路比较长，风阻比较大。 Another heat dissipation system uses a turbofan. As shown in FIG. 2 below, the radiator fins 201 and the turbofan 202 are arranged in parallel in the thickness direction of the projector. This heat dissipation structure is often used in notebook computers. However, this cooling system occupies a relatively large area, and the external cooling air flows in from the side of the casing, passing through the radiator fins 201 and the turbofan 202, so that the cooling air path is relatively long and the wind resistance is relatively large.
因此，如何提减小投影仪厚度，缩小风阻，是本技术领域人员亟待解决的问题。 Therefore, how to increase and reduce the thickness of the projector and reduce the wind resistance is an urgent problem to be solved by those skilled in the art.

本实用新型实施例提供了一种投影仪，包括投影仪主体1及用于对投影仪主体1散热的散热系统2，投影仪主体1上设置有贯穿其厚度方向设置的避让空间，散热系统2设置于所述避让空间内；散热系统2包括：沿投影仪主体1的厚度方向排列的风扇21及散热器鳍片22；，风扇21的导风方向与投影仪主体1的厚度方向相同。 The embodiment of the utility model provides a projector, including a projector main body 1 and a heat dissipation system 2 for dissipating heat from the projector main body 1. The projector main body 1 is provided with an escape space that runs through its thickness direction, and the heat dissipation system 2 The heat dissipation system 2 includes: a fan 21 and radiator fins 22 arranged along the thickness direction of the projector body 1;
本实用新型实施例提供的投影仪，将散热系统2设置于投影仪主体1的避让空间内，避免了投影仪主体1与散热系统2叠加而影响投影仪的整体厚度，通过将散热系统2的风扇21及散热器鳍片22沿投影仪主体1的厚度方向排列，风扇21使风从投影仪主体1的厚度方向的第一面11进入，流经散热器鳍片22，再从投影仪主体1的厚度方向的第二面12出去，避免了风扇21在投影仪主体1的厚度方向上的需求，进而降低了散热系统2在投影仪主体1的厚度方向上的需求，以便于减小投影仪的厚度；外界冷却风在进入外壳后沿投影仪主体1的厚度方向流动，缩短了外界冷却风在投影仪内的风路的直线距离，进而降低了风阻。 In the projector provided by the embodiment of the present invention, the heat dissipation system 2 is arranged in the avoidance space of the projector main body 1, which avoids the overlap of the projector main body 1 and the heat dissipation system 2 and affects the overall thickness of the projector. The fan 21 and radiator fins 22 are arranged along the thickness direction of the projector main body 1, and the fan 21 allows the wind to enter from the first surface 11 of the projector main body 1 in the thickness direction, flow through the radiator fins 22, and flow from the projector main body. 1 in the thickness direction of the second surface 12, avoiding the requirement of the fan 21 in the thickness direction of the projector body 1, thereby reducing the requirement of the cooling system 2 in the thickness direction of the projector body 1, so as to reduce the projection The thickness of the projector; the external cooling air flows along the thickness direction of the projector main body 1 after entering the casing, shortening the straight-line distance of the external cooling air in the air path of the projector, thereby reducing the wind resistance.
其中，需要说明的是，投影仪主体1的厚度方向为投影仪的顶部到其底部的方向，投影仪主体1的宽度方向为投影仪的前面(设置有投影光出口的一面)到期后面(设置有电源线插口的一面)的方向。而投影仪主体1上设置的避让空间为通过投影仪主体1的部件排列，形成用于容纳散热系统2的凹槽。该避让空间可以位于投影仪主体1的边缘，即，投影仪主体1的边角处具有凹槽；也可以使避让空间可以位于投影仪主体1的中间，即，投影仪主体1的中间具有凹槽。 Wherein, it should be noted that the thickness direction of the projector main body 1 is the direction from the top of the projector to its bottom, and the width direction of the projector main body 1 is from the front (the side with the projection light exit) to the rear ( The direction of the side where the power cord socket is set). The escape space provided on the projector main body 1 is formed by the arrangement of components of the projector main body 1 to form a groove for accommodating the cooling system 2 . The escape space can be located at the edge of the projector main body 1, that is, there is a groove at the corner of the projector main body 1; groove.
在本实施例中，风扇21为轴流风扇，风扇21的轴线沿投影仪主体1的厚度方向布置。也可以将风扇21设置为涡流风扇，在此不再详细介绍且均在保护范围之内。其中，风扇21的轴线即为其旋转轴的轴线。 In this embodiment, the fan 21 is an axial fan, and the axis of the fan 21 is arranged along the thickness direction of the projector main body 1 . The fan 21 can also be set as a vortex fan, which will not be described in detail here and is within the scope of protection. Wherein, the axis of the fan 21 is the axis of its rotating shaft.
投影仪的外壳上设置有进风口及出风口；进风口设置于外壳的顶面，出风口设置于外壳的底面；或，出风口设置于外壳的顶面，进风口设置于外壳的底面。其中，外壳的顶面为外壳靠近投影仪主体1的顶部的面，而外壳的底面为外壳靠近投影仪主体1的部部的面。 The casing of the projector is provided with an air inlet and an air outlet; the air inlet is arranged on the top surface of the casing, and the air outlet is arranged on the bottom surface of the casing; or, the air outlet is arranged on the top surface of the casing, and the air inlet is arranged on the bottom surface of the casing. Wherein, the top surface of the casing is the surface of the casing close to the top of the projector main body 1 , and the bottom surface of the casing is the surface of the casing close to the part of the projector main body 1 .
优选地，进风口和出风口与散热系统2对应设置。以外壳的顶面设置进风口且外壳的底面设置出风口为例，外壳顶面设置的进风口与散热系统2对齐，而外壳底面设置的出风口也与散热系统2对齐。在散热系统2的风扇21作用下，外界冷却风由进风口进入外壳，经过散热系统2后直接由出风口流出，即冷却风对投影仪的冷却路线为外壳顶面的厚度、外壳内部的厚度及外壳底面的厚度，使得冷却风经过的路程最短，进一步降低了风阻。 Preferably, the air inlet and air outlet are set corresponding to the cooling system 2 . Taking an air inlet provided on the top surface of the casing and an air outlet arranged on the bottom surface of the casing as an example, the air inlet arranged on the top surface of the casing is aligned with the heat dissipation system 2 , and the air outlet arranged on the bottom surface of the casing is also aligned with the heat dissipation system 2 . Under the action of the fan 21 of the heat dissipation system 2, the external cooling air enters the casing from the air inlet, and flows out directly from the air outlet after passing through the heat dissipation system 2, that is, the cooling route of the cooling air to the projector is the thickness of the top surface of the casing and the thickness of the inside of the casing. And the thickness of the bottom surface of the shell makes the path of the cooling air the shortest, further reducing the wind resistance.
也可以使进风口和出风口不与散热系统2对应设置，外界冷却风由进风口进入外壳后在外壳内部流过一段路程后流经散热系统2，再由出风口排出。在此不再详细介绍且均在保护范围之内。 It is also possible to make the air inlet and the air outlet not correspond to the heat dissipation system 2, and the external cooling air enters the casing through the air inlet and flows through the heat dissipation system 2 after a certain distance inside the casing, and then is discharged from the air outlet. It will not be introduced in detail here and is within the scope of protection.
如图4和图5所示，在本实用新型实施例提供的投影仪中，风扇21位于散热系统2靠近外壳的顶面的一侧，散热器鳍片22位于散热系统2靠近外壳的底面的一侧。即，风扇21与散热器鳍片22相互叠加，风扇21位于散热器鳍片22的上端。通过散热器鳍片22支撑风扇21，使其稳定运行。 As shown in Figure 4 and Figure 5, in the projector provided by the embodiment of the present invention, the fan 21 is located on the side of the heat dissipation system 2 close to the top surface of the housing, and the radiator fins 22 are located on the side of the heat dissipation system 2 close to the bottom surface of the housing. side. That is, the fan 21 and the radiator fins 22 overlap each other, and the fan 21 is located at the upper end of the radiator fins 22 . The fan 21 is supported by the radiator fins 22 for stable operation.
如图5和图6所示，为了进一步降低风阻，散热器鳍片22上的鳍片的数量为多个，多个鳍片垂直于投影仪主体的厚度方向排列，即散热器鳍片22在与投影仪主体厚度方向垂直的平面内呈横向或纵向排列(其中，横向是指从投影仪左视面到右视面的方向，纵向是指从投影仪主视面(出光面)到后视面的方向)，如图5所示为横向排列。在风扇21的转动下，外界冷却风由进风口进如外壳的内部，依次经过散热器鳍片22及风扇21(或风扇21及散热器鳍片22)，在散热器鳍片22的引导下外界冷却风在经过散热器鳍片22时，沿投影仪主体1的厚度方向流动，进而有效较少了外界冷却风经过散热器鳍片22的阻力。 As shown in Figures 5 and 6, in order to further reduce wind resistance, the number of fins on the radiator fins 22 is multiple, and the plurality of fins are arranged perpendicular to the thickness direction of the projector main body, that is, the radiator fins 22 Arranged horizontally or vertically in a plane perpendicular to the thickness direction of the projector main body (wherein, horizontally refers to the direction from the left viewing surface of the projector to the right viewing surface, and vertically refers to the direction from the main viewing surface (light-emitting surface) of the projector to the rear viewing surface. The direction of the surface), as shown in Figure 5, is arranged horizontally. Under the rotation of the fan 21, the external cooling air enters the inside of the casing from the air inlet, passes through the radiator fins 22 and the fan 21 (or the fan 21 and the radiator fins 22), and is guided by the radiator fins 22. When the external cooling air passes through the radiator fins 22 , it flows along the thickness direction of the projector main body 1 , thereby effectively reducing the resistance of the external cooling air passing through the radiator fins 22 .
为了确保散热效果，风扇21的数量为两个且沿投影仪主体1的宽度方向排列。也可以将风扇21的数量设置为一个活三个及以上，在此不做具体说明，仅需满足散热需求即可。 In order to ensure the cooling effect, there are two fans 21 arranged along the width direction of the projector main body 1 . It is also possible to set the number of fans 21 as one or three or more, which is not specifically described here, and only needs to meet the heat dissipation requirement.
在本实施例中，散热器鳍片22的数量为多个且均匀排列。 In this embodiment, the radiator fins 22 are multiple and uniformly arranged.
进一步地，如图5所示，两个风扇21的排列方向与多个散热器鳍片22的排列方向相同。即，一个风扇21与其对应的一部分散热器鳍片22共同完 成散热，另一个风扇21与其对应的另一部分散热器鳍片22共同完成散热，进而避免了多个散热器鳍片22之间的相互影响，确保了散热均匀性。 Further, as shown in FIG. 5 , the arrangement direction of the two fans 21 is the same as the arrangement direction of the plurality of radiator fins 22 . That is, one fan 21 and its corresponding part of the radiator fins 22 jointly complete the heat dissipation, and another fan 21 and its corresponding another part of the radiator fins 22 jointly complete the heat dissipation, thereby avoiding the heat dissipation between the plurality of radiator fins 22. Mutual influence ensures the uniformity of heat dissipation.
优选地，本实用新型实施例提供的投影仪中，散热系统2的厚度小于25mm。其中，风扇21及散热器鳍片22的厚度依实际需求而定。 Preferably, in the projector provided by the embodiment of the present invention, the thickness of the cooling system 2 is less than 25mm. Wherein, the thicknesses of the fan 21 and the radiator fins 22 are determined according to actual requirements.
为了便于设置，避让空间设置于投影仪主体1的边缘。 For the convenience of installation, the escape space is arranged on the edge of the projector main body 1 .
如图5所示，本实用新型实施例提供的投影仪还包括导热连接散热器鳍片22与投影仪主体1的导热板3，导热板3上可连接有导热管(未在图中示出)，导热管将投影仪主体1上的热量传导至导热板，通过散热器鳍片22散发出去。 As shown in Figure 5, the projector provided by the embodiment of the present invention also includes a thermally conductive plate 3 connecting the radiator fins 22 and the projector main body 1, and the thermally conductive plate 3 can be connected with a heat pipe (not shown in the figure). ), the heat pipe conducts the heat on the projector main body 1 to the heat conduction plate, and dissipates it through the radiator fins 22 .
