Description

Wind hood assembly and electronic device used therefor

This creation is about a wind deflector assembly, especially a wind deflector assembly applied to an electronic device.

With the rapid development of technology, the operating speed and performance of electronic devices have been continuously improved, and the heating power of the internal electronic components has also been continuously increased. In order to prevent electronic components from failing due to overheating, sufficient heat dissipation performance must be provided. For example, a fan is installed inside the electronic device, and the air flow generated by the fan is used to take the heat generated by the electronic component out of the electronic device. In addition, for electronic components with high heating power, such as central processing units or graphics chips, heat dissipation fins or other types of heat dissipation modules are usually added to match the airflow generated by the fan to reduce the temperature of these electronic components. .

In addition, the electronic device takes a server as an example, and the housing of the server is usually equipped with a diversion structure to assist heat dissipation to increase the efficiency of heat convection. For example, the air deflector is arranged on the outside of the main board of the server, and the fan is arranged on one side of the main board and corresponds to the air inlet of the air deflector. The air flow blown by the fan can be guided by the wind deflector, and then the heat generated by the electronic components on the motherboard can be dissipated out of the casing, thereby reducing the temperature of the server and stabilizing its operation.

If it is necessary to increase the heat dissipation effect, it is generally by increasing the speed of the fan to increase the flow rate of the airflow to dissipate the heat generated by the electronic components. However, this method of increasing the fan speed is quite energy-consuming, and there is a need for improvement.

In view of the above-mentioned problems, the main purpose of this creation is to provide an electronic device and a fan assembly. The wind guide assembly includes a wind guide and a shielding member. The shielding member is used to cover or open the opening of the wind guide. The novel structure solves the conventional problem of energy consumption by increasing the speed of the fan to improve the heat dissipation effect.

In order to achieve the above-mentioned purpose, this invention provides a wind deflector assembly applied to an electronic device. The electronic device includes a heating element area. The wind guide assembly includes a wind guide, a shield, a switch and a control module. The wind hood is used to cover the heating element area. The wind deflector includes a first side, a second side, an air inlet and at least one opening. The air inlet is located on the first side of the wind deflector, and the opening is arranged on the second side of the wind deflector. The first side and the second side are located in different axial directions. The shielding member is movably arranged on the wind deflector and corresponds to the opening. The switch is connected to the shielding element to control the shielding element to move between an open position and a shielding position. The control module is electrically connected to the switch. The control module includes a temperature sensing unit, and the temperature sensing unit detects an ambient temperature in the area of the heating element. When the ambient temperature is greater than a first preset value, the control module turns on the switch to move the shielding member to the open position.

In order to achieve the above-mentioned purpose, the present invention provides another electronic device, which includes a heating element area, a wind deflector assembly, and a control module. The wind hood assembly is used to cover the heating element area. The wind guide assembly includes a wind guide, a shield and a switch. The wind deflector includes a first side, a second side, an air inlet and at least one opening. The air inlet is located on the first side of the wind deflector, and the opening is arranged on the second side of the wind deflector. The first side and the second side are located in different axial directions. The shielding member is movably arranged on the wind deflector and corresponds to the opening. The switch is connected to the shielding element to control the shielding element to move between an open position and a shielding position. The control module is electrically connected to the switch. The control module includes a temperature sensing unit, and the temperature sensing unit detects an ambient temperature in the area of the heating element. When the ambient temperature is greater than a first preset value, the control module turns on the switch to move the shielding member to the open position.

According to an embodiment of the present invention, when the ambient temperature is less than a second preset value, the control module turns off the switch to move the shielding member to the shielding position.

According to an embodiment of the present invention, the axial direction of the air inlet is perpendicular to the axial direction of the opening.

According to an embodiment of the present invention, when the shielding member is located at the shielding position, the airflow inside the electronic device flows through the heating element area from the air inlet.

According to an embodiment of the present invention, when the shielding member is in the open position, the airflow inside the electronic device flows through the heating element area from the air inlet and the opening.

According to an embodiment of the present invention, the openings of the wind deflector correspond to the heating element area.

Based on the above, according to the electronic device and wind deflector assembly of this creation, the wind deflector assembly includes the wind deflector, the shield and the switch. Wherein, the wind deflector is arranged outside the heating element area, and includes an air inlet and an opening. The shielding member is movably arranged on the wind deflector and corresponds to the opening. The switch is connected with the shield to control the shield to move between the open position and the shield position. In addition, the control module of the electronic device or the wind deflector assembly is electrically connected to the switch. When the ambient temperature is greater than the first preset value, the control module turns on the switch to move the shielding member to the open position to increase the volume of cold air entering the heating element area, thereby reducing the ambient temperature of the heating element area. Therefore, by controlling the movement of the shielding member, the effect of improving the heat dissipation effect can be achieved in such a way that hardly consumes energy.

In order to let your review committee know more about the technical content of this creation, some preferred specific embodiments are described as follows.

FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the creation, and FIG. 2 is a schematic diagram of the air deflector shown in FIG. 1 on the inner side. Please refer to FIG. 1 and FIG. 2. The electronic device E can be, for example, but not limited to, a computer, or a server, and the electronic device E includes a heating element area H. It should be noted that, in order to simplify the drawing, the electronic device E only draws the part of the heating element area H. Specifically, the electronic device E has a plurality of electronic components C that generate heat during operation, and the area where these electronic components C are arranged is referred to as the heating element area H herein. For example, the heating element area H may be an area where the main board is arranged.

In this embodiment, the electronic device E includes a wind deflector assembly 1. Wherein, the wind hood assembly 1 includes a wind hood 10, a shield 20 and a switch 30. Wherein, the wind hood 10 of the wind hood assembly 1 is arranged outside the area H of the heating element. For example, the wind deflector 10 may be a cover body to cover the outside of the heating element area H (such as the main board). In this embodiment, the air guide hood 10 may include an air inlet 11, an air outlet 12 and at least one opening 13. In order to clearly illustrate the positions of the air inlet 11, the air outlet 12, and the opening 13, the air deflector 10 is divided into a first side 14 and a second side 15, and the first side 14 and the second side 15 are located in different axial directions. Specifically, the wind deflector 10 includes a first side 14 and a second side 15. The first side 14 is the side surface of the wind deflector 10 (four sides are taken as an example in this embodiment), and the second side 15 is the wind deflector The top side of 10 makes the first side 14 substantially perpendicular to the second side 15.

The air inlet 11 and the air outlet 12 are both located on the first side 14 of the wind deflector 10, and the air inlet 11 and the air outlet 12 are respectively located at two opposite ends of the first side 14 of the wind deflector 10. Specifically, the air inlet 11 is located at one end 141 of the first side 14, and the air outlet 12 is located at the opposite end 142 of the first side 14. It should be noted that since the opposite end 141 and the other end 142 of the first side 14 respectively have the air inlet 11 and the air outlet 12, their positions are indicated by arrows in FIGS. 1, 2 and 3 respectively.

In addition, the wind deflector 10 of this embodiment is illustrated by taking a plurality of openings 13 as an example. Specifically, the opening 13 is provided on a second side 15 of the wind deflector 10, and this embodiment takes the top side as an example. Since the first side 14 and the second side 15 are located in different axial directions, the air inlet 11 and the opening 13 are also located in different axial directions. Specifically, the side surface (or cross section) of the wind deflector 10 of this embodiment is an inverted U-shaped structure. In addition to the two sides, there is a second side 15. The first side 14 and a second side 15 are perpendicular to each other, so the second side 15 and the air inlet 11 are perpendicular to each other. In addition, the opening 13 of this embodiment is arranged on the second side 15, so that the air inlet 11 and the second side 15 with the opening 13 are perpendicular to each other, that is, the air inlet 11 and the opening 13 do not overlap, and the axis of the air inlet 11 To the axial direction of the vertical opening 13. Preferably, the opening 13 of the wind deflector 10 corresponds to the area H of the heating element.

As shown in FIG. 2, the shielding member 20 is disposed on the wind guide 10 and corresponds to the opening 13. For example, the shield 20 may be disposed on the second side 15. In this embodiment, the shielding member 20 is movably disposed on the wind deflector 10 to shield or expose the opening 13, as shown in FIGS. 2 and 3. FIG. 3 is a schematic diagram of the opening shown in FIG. 2 being shielded by the shielding member. Specifically, the switch 30 is connected to the shielding member 20 to control the shielding member 20 to move between an open position (as shown in FIG. 2) and a shielding position (as shown in FIG. 3). For example, the switch 30 has a connecting rod (not shown in the figure) that is actuated by opening and closing, and is connected to the shield 20 through the connecting rod. When the switch 30 is turned on, the connecting rod can drive the shield 20 to move to the open position, as shown in FIG. 2, to expose the opening 13. When the switch 30 is closed, the connecting rod can drive the shielding member 20 to move to the shielding position, as shown in FIG. 3, to shield the opening 13. In other embodiments, the switch 30 can also be connected to the shielding member 20 in other structures. The present invention is not limited, and it is only necessary to control the shielding member 20 to move between the open position and the shielding position. Preferably, the wind deflector 10 may also have a sliding groove (not shown), and the shielding member 20 may be arranged in the sliding groove to move between the open position and the shielding position.

In addition, the electronic device E of this embodiment further includes a control module 40 electrically connected to the switch 30 of the wind deflector assembly 1. The switch 30 may be an electromagnetic switch, and the switch 30 is controlled to be turned on and off through the control module 40. Wherein, the control module 40 can be installed in the wind deflector 10 or the electronic device E, and this embodiment is described by taking the installation in the electronic device E as an example. FIG. 4 is a block diagram of the electronic device shown in 1, please refer to FIG. 1, FIG. 2 and FIG. 4. The control module 40 of this embodiment includes a temperature sensing unit 41, and the temperature sensing unit 41 can detect an ambient temperature of the heating element region H. In addition, the control module 40 stores a first preset value and a second preset value, and determines whether to turn on or off the switch 30 based on the relationship between the ambient temperature, the first preset value, and the second preset value.

Specifically, when the ambient temperature is greater than the first preset value, the control module 40 turns on the switch 30 to move the shielding member 20 to the open position (as shown in FIG. 2). For example, the first preset value may be set to 50°C. When the thermal energy generated by the operation of the electronic component C in the heating element area H causes the ambient temperature of the heating element area H to exceed 50°C, the control module 40 can energize the switch 30 to turn on the switch 30. In other words, the switch of the wind deflector assembly 1 is controlled by the control module 40 of the electronic device E. After the switch 30 is turned on, the shielding member 20 can be moved to the open position to expose the opening 13. At this time, the airflow inside the electronic device E (for example, the airflow generated by a fan) can flow from the air inlet 11 and the opening 13 through the heating element area H, and move in the direction of the air outlet 12, thereby dissipating the heating element in the area H Thermal energy generated by the electronic component C.

When the ambient temperature of the heating element area H drops, the control module 40 turns off the switch 30 to move the shielding member 20 to the shielding position. For example, the second preset value may be set to 30°C. When the ambient temperature is lower than the second preset value (30°C), the control module 40 may power off the switch 30 to turn off the switch 30. After the switch 30 is closed, the shielding member 20 can be driven to move to the shielding position to shield the opening 13, as shown in FIG. 3. At this time, the air flow inside the electronic device E flows from the air inlet 11 through the heating element area H and moves in the direction of the air outlet 12.

Specifically, a fan (not shown in the figure) is provided inside the electronic device E. In a general state, the shield 20 is located at the shielding position, and the air flow generated by the fan can flow from the air inlet 11 through the heating element area H and move in the direction of the air outlet 12. When the thermal energy generated by the operation of the electronic component C is too much to dissipate only through the air inlet 11 and the air outlet 12, the ambient temperature of the heating element area H will increase. It should be noted that the conventional air guide hood also guides the air flow generated by the fan from the air inlet to the air outlet to dissipate the heat generated by the electronic component C in the heating element area. However, when the ambient temperature rises, it is conventionally known to increase the speed of the fan to increase the efficiency of heat dissipation.

In this embodiment, the switch 30 is turned on by the control module 40 to move the shielding member 20 to the open position (as shown in FIG. 2). At this time, in addition to the air inlet 11, the air flow (cold air) generated by the fan can also enter the air duct 10 from the opening 13 and flow through the heating element area H (turned into hot air), and then escape from the air outlet 12 to generate heat The outside of the element area H, thereby reducing the ambient temperature of the heating element area H. In other words, it is not necessary to cool the heat-generating electronic component C in an energy-consuming manner (increasing the fan speed), and only by moving the shielding member 20 to the open position, the same effect of cooling the heat-generating electronic component C can be achieved.

The present invention also provides a wind deflector assembly 1 which is applied to an electronic device E. Since the main component structure and connection relationship of the electronic device E and the wind deflector assembly 1 are the same as the previous embodiment, the component symbols are used. In short, the electronic device E includes a heating element area H. In addition, please refer to FIG. 5, which is a block diagram of the wind deflector assembly according to another embodiment of the creation. The wind deflector assembly 1 includes a wind deflector 10 (refer to FIG. 1 ), a shield 20, a switch 30 and a control module 40. The control module 40 also includes a temperature sensing unit 41 to detect the ambient temperature of the heating element area H. The control module 40 is electrically connected to the switch 30 to control the switch 30 so that the shielding member 20 can move between the open position and the shielding position. Regarding the structure, connection relationship, and control method of the wind deflector 10, the shielding member 20, the switch 30, and the control module 40 are the same as the foregoing embodiment, please refer to the foregoing embodiment, which is not repeated here.

To sum up, according to the electronic device and wind deflector assembly of this creation, the wind deflector assembly includes the wind deflector, the shield and the switch. Wherein, the wind deflector is arranged outside the heating element area, and includes an air inlet and an opening. The shielding member is movably arranged on the wind deflector and corresponds to the opening. The switch is connected with the shield to control the shield to move between the open position and the shield position. In addition, the control module of the electronic device or the wind deflector assembly is electrically connected to the switch. When the ambient temperature is greater than the first preset value, the control module turns on the switch to move the shielding member to the open position to increase the volume of cold air entering the heating element area, thereby reducing the ambient temperature of the heating element area. Therefore, by controlling the movement of the shielding member, the effect of improving the heat dissipation effect can be achieved in such a way that hardly consumes energy.
