Description

Technical Field

[0001] The present invention relates to the field of heat dissipation equipment, and in particular to an intelligent heat dissipation device and method for a display. Background Art

[0016] Furthermore, the heat dissipation slot is arranged to be tilted downward, and the tilt angle is 30-60 degrees.

[0017] Furthermore, limiting grooves are provided at the four corners of the heat dissipation shell, limiting blocks are slidably installed in the limiting grooves, a supporting spring is provided between the limiting blocks and the bottom wall of the limiting grooves, and a telescopic component is provided between the two vertical limiting blocks, and the telescopic component is used to adjust the distance between the two vertical limiting blocks.

[0018] Furthermore, the telescopic assembly includes two symmetrically distributed transverse grooves, a sliding member is slidably installed in the transverse groove, an automatic telescopic rod is arranged between the sliding member and the transverse groove, a limit stop rod is arranged on the sliding member, and the upper and lower sides of the limit stop rod are in contact with the two vertical side surfaces of the limit blocks at the same time.

[0019] Furthermore, a plurality of metal parts are arranged on the limiting shell, the metal parts are in contact with the display to achieve heat conduction, and dustproof nets are arranged on the outer sides of the heat dissipation grooves of the heat dissipation fan.

[0026] (1) The present invention is provided with a heat dissipation module, and a detection unit in the heat dissipation module is used to detect the temperature of the display in real time when the display is working. Once the detected temperature reaches the set temperature, it means that the display is in a state of poor heat dissipation effect.

[0028] (3) The present invention energizes the electromagnetic strip, and the strong magnetic force generated instantly pushes the magnet to move outward, thereby forcing the No. 1 connecting rod and the No. 2 connecting rod to be squeezed onto the hinge shaft. Since one end of the hinge shaft is larger than the other end, the connection between the No. 1 connecting rod and the No. 2 connecting rod is in a relatively fixed state under the action of thrust. Therefore, the original No. 1 connecting rod and the No. 2 connecting rod form a linkage state. As long as other switching plates are closed, the linkage of multiple switching plates can be realized, thereby achieving the purpose of ensuring that the switching components synchronously close the heat dissipation slot, and the reliability is higher.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 6 As shown, the present invention is an intelligent heat dissipation device for a display, comprising a heat dissipation housing 1, on which a heat dissipation module is also provided, and the heat dissipation module comprises:

[0039] An air cooling unit 2, the air cooling unit 2 is used to air cool the heat dissipation housing 1;

[0040] A detection unit, wherein the detection unit is used to detect the temperature of the display;

[0041] The control unit is used to selectively control the operation of the air cooling unit 2 according to the detection result of the detection unit.

[0042] Furthermore, the air cooling unit 2 comprises:

[0043] Heat dissipation slots 21, the heat dissipation slots 21 are opened on the heat dissipation housing 1, and at least two groups of heat dissipation slots 21 are provided, and are arranged in groups of two in a diagonal manner on the heat dissipation housing 1; a heat dissipation fan 22 is correspondingly provided at one group of the heat dissipation slots 21, one heat dissipation fan 22 is used to guide the airflow outward, and the other heat dissipation fan 22 is used to guide the airflow inward;

[0044] The other heat dissipation slots 21 are provided with a switching component 23, and the switching component 23 is used to close the corresponding heat dissipation slot 21 when the two heat dissipation fans 22 work at the same time.

[0045] In order to solve the technical problem in the prior art that the back of the display is close to the wall, resulting in too small a gap and thus affecting heat dissipation, a heat dissipation module is provided. The detection unit in the heat dissipation module is used to detect the temperature of the display in real time when it is working. Once the detected temperature reaches the set temperature, it means that the display is in a state of poor heat dissipation effect. Therefore, in order to accelerate the cooling and heat dissipation, the air cooling unit 2 is controlled to work, actively cool the display, and accelerate the gas circulation to achieve the effect of rapid heat dissipation and cooling.

[0046] The specific operation of the air cooling unit 2 is as follows. Under normal conditions, the switching component 23 is in a stationary contracted state, thereby maintaining the normally open state of all the heat dissipation slots 21, thereby realizing a natural cooling method. However, when the temperature of the display rises rapidly to the first set temperature, in order to accelerate the heat dissipation, a heat dissipation fan 22 is first started to accelerate the gas export or import, thereby accelerating the speed of gas replacement and achieving the purpose of rapid heat dissipation. If the temperature of the display gradually drops to a normal range, the heat dissipation fan 22 is stopped and the heat is naturally dissipated. If the temperature continues to rise, when it reaches the second set temperature, it means that the heat dissipation effect is still lacking. Therefore, two heat dissipation fans 22 are simultaneously enabled to accelerate the gas entry and export, thereby further improving the cooling and heat dissipation effect. In order to prevent other heat dissipation slots 21 from affecting the flow rate of the airflow, the switching component 23 is used to close other heat dissipation slots 21, leaving only the heat dissipation slots 21 that specifically accelerate the air intake and the heat dissipation slots 21 that specifically accelerate the air outlet, so that the two heat dissipation fans 22 that cooperate with each other reach the best working state, further improving the heat dissipation and cooling effect of the display.

[0047] Furthermore, the switching component 23 includes a slide groove 231, the slide groove 231 is opened on one side of the heat dissipation groove 21, a slider 233 is connected in the slide groove 231 through a memory alloy spring 232, and a switching plate 234 is connected to the slider 233; two adjacent switching plates 234 are connected through a linkage component 24;

[0048] The switch plate 234 is opened in a normal state, and is closed under the action of the linkage component 24 when the two cooling fans 22 work simultaneously.

[0049] The present invention provides a specific structure of a switching component 23. When in use, in the initial state, the memory alloy spring 232 is in a contracted state, thereby driving each connected switching plate 234 and the heat sink 21 to be in a staggered state, so that the heat sink 21 is unobstructed and natural heat dissipation is achieved. However, once the two heat dissipation fans 22 work at the same time, it means that the heat dissipation demand of the display is at a higher level, so the temperature will reach the second set temperature, so the memory alloy spring 232 will stretch and deform after being heated, and push the switching plate 234 to cover the heat sink 21, leaving only one group of heat sinks 21 cooperating with the heat sink fan 22 to work, so as to maximize the working effect of the heat sink fan 22; and the above-mentioned method of closing other heat sinks 21 does not need to be driven by a special driving component, but only needs to use the memory alloy spring 232 that automatically deforms by temperature changes, which is quick and convenient, and saves electricity and energy.

[0050] Furthermore, the linkage assembly 24 includes a No. 1 connecting rod 241, a No. 2 connecting rod 242 and a hinge shaft 243, the diameter of the hinge shaft 243 gradually decreases toward one end of the heat dissipation shell 1, the No. 1 connecting rod 241 and the No. 2 connecting rod 242 are both provided with hinge holes 244 and are jointly sleeved on the hinge shaft 243 to form a movable connection, the No. 1 connecting rod 241 and the No. 2 connecting rod 242 are respectively hinged on their respective corresponding switching plates 234, and a magnet 245 is provided at one end of the movable connection of the No. 1 connecting rod 241 and the No. 2 connecting rod 242; an electromagnetic strip 246 is provided at the position of the heat dissipation shell 1 corresponding to the linkage assembly 24, and the electromagnet 245 is electrically connected to the control unit.

[0051] In order to reduce the problem caused by too many times of contraction and extension deformation of the memory alloy spring 232, the present invention adds a linkage component 24 to insure the synchronous closing action of multiple switch plates 234, thereby improving the success rate and stability of the switch component 23. Specifically, when in use, under normal conditions, the electromagnetic strip 246 that is not energized to obtain magnetism emits magnetism, so that the No. 1 connecting rod 241 and the No. 2 connecting rod 242 are in a state of active connection, and the action of the switch plate 234 will not affect the action of the No. 1 connecting rod 241 and the No. 2 connecting rod 242. However, when the synchronous closing action of the switch plate 234 is required, the electromagnetic strip 246 is supplied with magnetism. When power is turned on at 46, the strong magnetic force generated instantly pushes the magnet 245 to move outward, thereby forcing the No. 1 connecting rod 241 and the No. 2 connecting rod 242 to be squeezed onto the hinge shaft 243. Since one end of the hinge shaft 243 is larger than the other end, the connection between the No. 1 connecting rod 241 and the No. 2 connecting rod 242 is in a relatively fixed state under the action of the thrust. Therefore, the original No. 1 connecting rod 241 and the No. 2 connecting rod 242 form a linkage state. As long as other switching plates 234 are closed, the linkage of multiple switching plates 234 can be achieved, thereby achieving the purpose of ensuring that the switching component 23 synchronously closes the heat dissipation slot 21, and the reliability is higher.

[0052] Furthermore, the heat dissipation slots 21 are arranged to be tilted downward, and the tilt angle is 30-60 degrees.

[0053] Through the above arrangement, dust from the outside is not easy to enter the heat dissipation slot 21, and the accumulation of dust for a long time and the blockage of the heat dissipation slot 21 in a serious state can be avoided as much as possible.

[0054] Limiting grooves 3 are arranged at the four corners of the heat dissipation shell 1, and limiting blocks 4 are slidably installed in the limiting grooves 3. A supporting spring 5 is arranged between the limiting blocks 4 and the bottom wall of the limiting grooves 3, and a telescopic component 6 is arranged between the two vertical limiting blocks 4. The telescopic component 6 is used to adjust the distance between the two vertical limiting blocks 4.

[0055] Furthermore, the telescopic assembly 6 includes two symmetrically distributed transverse grooves 61, a sliding member 62 is slidably installed in the transverse groove 61, an automatic telescopic rod 64 is arranged between the sliding member 62 and the transverse groove 61, and a limit stop rod 63 is arranged on the sliding member 62, and the upper and lower sides of the limit stop rod 63 are in contact with the two vertical side surfaces of the limit blocks 4 at the same time.

[0056] Furthermore, a plurality of metal parts 7 are provided on the limiting housing, and the metal parts 7 are in contact with the display to achieve heat conduction. A dustproof net 8 is provided on the outer side of the heat dissipation slot 21 of the heat dissipation fan 22 .

[0057] In the present invention, through the cooperation of the limit groove 3, the limit block 4 and the telescopic assembly 6, the installation space formed by the four limit blocks 4 can be changed, so as to be suitable for the installation specifications on the back of different displays, and the convenience of installation and connection is improved. Specifically, the automatic telescopic rod 64 automatically extends, thereby pushing the connected sliding member 62 to move, and then driving the limit blocking rod 63 to move. When the limit blocking rod moves outward, the limit block 4 slides outward under the action of the support spring 5, so that the installation space of the heat dissipation shell 1 is increased. When the limit blocking rod 63 moves inward, the limit block 4 compresses the support spring 5 to slide inward, so that the installation space of the heat dissipation shell 1 is reduced. The purpose of synchronously reducing or increasing the installation space of the heat dissipation shell 1 is achieved through the above process, which plays a role in increasing the adaptable specifications and is more convenient. At the same time, the metal part 7 and the dustproof net 8 are used to achieve the purpose of enhancing thermal conductivity and enhancing dustproof effect.

[0059] S1: Install the heat dissipation housing 1 to the back of the display, and adjust the position of the upper limit block 4 of the heat dissipation housing 1 by using the telescopic component 6 until the distance between the display and the limit block 4 is appropriate, and then fix the display and the heat dissipation housing 1 by bolts to complete the installation steps;

[0060] S2: When the display is in use, the temperature of the display is detected by the detection unit, and according to the detected temperature reaching the preset first set temperature and the second set temperature, the control unit starts the air cooling unit 2;

[0061] S3: When the first set temperature is reached, the two cooling fans 22 of the air cooling unit 2 work synchronously to accelerate the introduction and export of gas to dissipate heat and cool down;

[0062] S4: When the second set temperature is reached, the switching component 23 of the air cooling unit 2 works to close the heat dissipation slots 21 except for the heat dissipation fan 22 installed thereon, so as to achieve further heat dissipation and temperature reduction.
