DETAILED DESCRIPTION

[0019] 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.

[0020] Embodiment 1 A solar controller that is easy to dissipate heat, according to Figure 1-Figure 4As shown, it includes a controller housing 1 and a base 4; the rear of the controller housing 1 is connected to the base 4; an annular flow guide cavity 4002 is opened in the base 4; a plurality of ventilation holes are arranged at the upper and lower parts of the controller housing 1; the base 4 is connected to an auxiliary positioning component; the auxiliary positioning component is used to assist in fixing the base 4 so that the solar controller remains horizontal; It also includes an extractor 5, a duct 6 and a guide head 7; two extractors 5 distributed on the left and right are installed on the upper part of the controller housing 1, and a fan is arranged inside the extractor 5; each extractor 5 is connected to a duct 6; all the ducts 6 are connected to the heat dissipation groove 4001 at one end away from the extractor 5; a plurality of guide heads 7 are installed at the lower part of the base 4; the heat dissipation groove 4001 is connected to all the guide heads 7; a gap is left between the controller housing 1 and the guide head 7.

[0021] The front end of the guide head 7 is tilted upwards, so as to guide the wind blown out of the guide head 7 upwards.

[0022] It also includes positioning pins 2 and elastic parts 3; four positioning pins 2 are fixedly connected to the base 4; each positioning pin 2 is fixedly connected to an elastic part 3; the elastic part 3 is a spring; the controller housing 1 is slidably connected to all the positioning pins 2; the controller housing 1 is in contact and fit with all the elastic parts 3; each positioning pin 2 is screwed with a fixing bolt for pressing the controller housing 1 onto the elastic part 3.

[0023] It also includes a heat sink 1001 ; a plurality of heat sinks 1001 are installed at the rear of the controller housing 1 ; and the end of each guide head 7 is located between two adjacent heat sinks 1001 .

[0024] Each heat sink 1001 is provided with a plurality of evenly distributed heat dissipation holes 1002 .

[0025] The heat dissipation slot 4001 is located in the middle of the base 4 , and a semiconductor cooler and a temperature sensor are arranged in the heat dissipation slot 4001 ; the heat dissipation slot 4001 corresponds to the position of the heat sink 1001 , and the heat dissipation slot 4001 is used to provide space for heat exchange of the heat sink 1001 .

[0026] The working steps of the above embodiment are: Before using this device, first connect the positive and negative wires 001 of the external mobile power supply to the two wiring positions in the middle of the six wiring holes reserved on the controller housing 1, and then connect the positive and negative wires 001 of the solar panel to the two wiring positions on the left, and then connect the positive and negative wires 001 of the load to the two wiring positions on the right. Put the solar panel in the sun, and start to set the built-in program of the controller housing 1 through the buttons on the controller housing 1. After the operator completes the setting of the controller housing 1, the operator moves the solar controller to a well-ventilated wall that avoids direct sunlight, and makes the base 4 close to the wall. Fix the solar controller to the wall through the bolt holes on the base 4. The solar controller can then start to work normally and comprehensively regulate the relationship between the solar panel, power supply and load.

[0027] Among them, the solar controller in the prior art generally has a fan installed in the solar controller, which forces air flow to allow outside air to enter the solar controller for cooling, and discharges the heat inside the solar controller to the outside through air flow to achieve the heat dissipation effect, or a heat sink is installed in the solar controller to discharge the heat inside the solar controller to the surrounding environment by heat conduction. When the solar controller operates within the rated power, the above heat dissipation can meet the use requirements and ensure the safe and stable operation of the solar controller. However, when the operating load increases and the solar controller needs to overclock, the solar controller will generate a lot of heat, which cannot be effectively dissipated by the above heat dissipation method. The heat inside is effectively discharged, and the heat accumulation causes the solar controller to be easily burned or its service life is greatly reduced. At this time, under the premise of retaining the air inlet and exhaust holes of the solar controller itself, an extractor 5 is set to extract the hot air in the controller casing 1, and the excess heat is extracted from the controller casing 1 in such a way as to force air flow, thereby realizing primary cooling of the controller casing 1, and a positioning pin 2 and an elastic member 3 are connected between the base 4 and the controller casing 1, so that the controller casing 1 is away from the wall, and a heat dissipation groove 4001 is provided on the base 4 to reduce the contact area between the base 4 and the wall, effectively avoiding the heat accumulation on the wall. The heat cannot be dissipated in time, and will be dissipated again through heat radiation. The solar controller is heat-conducted for the first time, and then the heat sink 1001 is arranged on the controller housing 1 in accordance with the prior art to conduct the heat generated in the controller housing 1, thereby realizing the secondary cooling of the controller housing 1, and then the hot air extracted by the aspirator 5 is introduced into the heat sink 4001 through the conduit 6. When the hot air flows in the heat sink 4001, the temperature sensor in the heat sink 4001 detects that the temperature entering the heat sink 4001 is too high, and controls the semiconductor refrigerator in the heat sink 4001 to start. The semiconductor refrigerator cools the hot air, and then the air temperature in the heat sink 4001 drops, and then it is discharged to the position between the adjacent heat sinks 1001 through the guide head 7, wherein the guide head is connected to the heat sink 4001 by the guide head 7. The front end of 7 is tilted upward, so that the cold air blown out of the heat sink 4001 is guided to the position of the heat sink 1001 as much as possible, and the heat between the heat sink 1001 and the wall is guided, so that the temperature of the wall is reduced, thereby reducing the infrared radiation heating of the wall to the solar controller. The heat sink 1001 is matched with the heat dissipation holes 1002 thereon, which increases the contact area between the heat sink 1001 and the cold air, so that the heat exchange efficiency of the heat sink 1001 is higher, thereby cooling the heat sink 1001, facilitating heat exchange between the heat sink 1001 and the electrical components in the controller housing 1, thereby realizing three-level cooling of the controller housing 1, facilitating the heat dissipation of the solar controller, and making the temperature in the controller housing 1 quickly return to a normal level.This allows the solar controller to operate safely and efficiently when overclocked, and also prevents the service life of the electrical components in the solar controller from being greatly reduced at high temperatures.

[0028] The front end of the guide head 7 is tilted upward to prevent the cold air blown out of the heat dissipation slot 4001 from directly entering the high-temperature controller housing 1 through the air inlet hole at the bottom of the controller housing 1, and no semiconductor refrigerator is directly arranged at the air inlet hole at the bottom of the controller housing 1 to cool the air entering the controller housing 1 first, and to prevent the temperature of the electrical components in the controller housing 1 from dropping suddenly after the semiconductor refrigerator cools the air, causing thermal stress of the electrical components, easily leading to fatigue and damage of the electrical components, and causing aging of the electrical components, shrinking The service life of the solar controller is shortened, and during the heat exchange between the heat sink 1001 and the air, the contact area between the heat sink 1001 and the air is large, which makes it easier for the heat sink 1001 to capture dust particles in the air. The upwardly tilted guide head 7 guides the cold air to the heat sink 1001, which can not only cool the heat sink 1001 and increase the heat exchange efficiency of the heat sink 1001, but also make the cold air blow toward the heat sink 1001 in a directional manner to remove the dust on the heat sink 1001, so as to prevent the dust from adhering to the heat sink 1001 and affecting the heat dissipation effect of the heat sink 1001.

[0029] Second embodiment On the basis of the first embodiment, according to Figure 1-Figure 2 and Figure 5-Figure 8 As shown, it also includes a support 101, a connecting rod 102, a magnetic block 103, an electromagnet 104 and a snap ring 105; six equidistantly distributed supports 101 are installed at the lower part of the controller housing 1; each support 101 is rotatably connected to a connecting rod 102; a magnetic block 103 is fixed to the rear of each connecting rod 102; six equidistantly distributed electromagnets 104 are installed at the lower part of the base 4; each electromagnet 104 is located above a magnetic block 103; each connecting rod 102 has a U-shaped groove 10201 on the side away from the magnetic block 103; six equidistantly distributed snap rings 105 are arranged at the bottom of the controller housing 1, and the snap rings 105 are made of rubber; each snap ring 105 is in contact with and cooperates with a connecting rod 102, and the connecting rod 102 rotates and drives the snap ring 105 to move downward, and synchronously pulls the wire 001 out of the controller housing 1; the snap ring 105 is sleeved on the wire 001.

[0030] The connection position between the support 101 and the connecting rod 102 is located at the rear center of the connecting rod 102, which is used to reduce the force arm from the magnet 103 to the center of the connecting rod 102, and increase the force arm from the center of the connecting rod 102 to the retaining ring 105. When the connecting rod 102 rotates, the distance that the connecting rod 102 pushes the retaining ring 105 downward is increased, so that the wire 001 is completely separated from the controller housing 1.

[0031] It also includes an arc-shaped spring 201 and a pull rope 202; the base 4 is fixed with six equidistantly distributed arc-shaped springs 201; all the arc-shaped springs 201 are fixed with the controller housing 1; each arc-shaped spring 201 is fixed with a pull rope 202; each pull rope 202 is fixed with a connecting rod 102; the connection position between the pull rope 202 and the connecting rod 102 is located between the center of the connecting rod 102 and the magnetic block 103.

[0032] The working steps of the above embodiment are: On the basis of the first embodiment, it should also be considered that six wires 001 are connected to the lower part of the controller housing 1, which are respectively connected to a mobile power supply, a solar panel and a load. When the temperature inside the solar controller is too high but the solar controller is still working for a long time, the heat in the controller housing 1 cannot be dissipated in time. Disconnecting the electrical connection with the solar controller in time is also a way to protect the solar controller, solar panel, power supply and load, and avoid causing spontaneous combustion of related parts and equipment.

[0033] In the prior art, there is a method of protecting the load by setting an electromagnetic relay to disconnect the connection between the controller and the load, while the electrical connection between the mobile power supply, the solar panel and the solar controller is still there. If the controller catches fire, the flame will easily spread along the wire 001 to the mobile power supply and the solar panel, causing a fire. Therefore, in order to avoid such a situation, before connecting the wire 001 to the lower part of the controller housing 1, first pass the wire 001 through the rubber clamp 105, and then connect the wire 001 to the controller housing 1. The wire 001 and the controller housing 1 are fixed by magnetic attraction, and then the clamp 105 is pushed to slide on the wire 001 until the clamp 105 contacts the connecting rod 102. When the temperature sensor in the heat sink 4001 detects that the temperature of the air drawn out of the controller housing 1 is high for a long time, the electromagnet 104 is controlled to start at this time, and the electric The magnet 104 generates magnetism, and the electromagnet 104 attracts the magnetic block 103, so that the connecting rod 102 rotates, and the connecting rod 102 pushes the clamping ring 105 to move downward. The friction between the rubber clamping ring 105 and the wire 001 is large. When the clamping ring 105 moves downward, it also drives the wire 001 to move downward, so that the wire 001 is withdrawn from the controller housing 1 to achieve electrical connection with the solar controller. It is necessary to control the order in which the wires 001 are pulled out. First, the solar controller is disconnected from the load, and then the electrical connection of the external power supply is disconnected, and finally the electrical connection of the solar panel is disconnected. It is only necessary to select electromagnets 104 with different numbers of turns so that the electromagnets 104 generate different suction forces, thereby attracting the corresponding magnetic blocks 103, so that the corresponding magnetic blocks 103 move toward the corresponding electromagnets 104, and the power-off sequence is controlled in an orderly manner to achieve overheating protection for the solar controller.

[0034] On the basis of the above work, after the solar controller is installed in a fixed position on the wall, if the solar controller is violently impacted, the controller housing 1 can be buffered by four elastic members 3 to disperse the impact energy received by the controller housing 1. At the same time, after the controller housing 1 is impacted, the controller housing 1 moves toward the direction close to the base 4, and the wire 001 moves backward in the corresponding U-shaped groove 10201, such as Figure 7 and Figure 8 As shown, at the same time, the controller housing 1 causes all the arc-shaped spring pieces 201 to bulge and deform upward, thereby, each arc-shaped spring piece 201 forces the corresponding rear portion of the connecting rod 102 to tilt upward through each pull rope 202, and the front portion of all the connecting rods 102 moves downward, driving the corresponding clamping ring 105 to move downward, thereby driving all the wires 001 to move downward synchronously, so that all the wires 001 are electrically disconnected from the controller housing 1 at the same time, thereby avoiding the above process. When the wires 001 are pulled out one by one, after the solar controller is shocked and catches fire, the flame spreads along the remaining wires 001 that are still electrically connected, thereby achieving shock protection for the solar controller and avoiding further expansion of property losses.

[0035] The third embodiment On the basis of the second embodiment, according to Figure 1-Figure 2 and Fig. 9 As shown, the auxiliary positioning assembly includes a level 301 ; two left-right symmetrical levels 301 are installed at the lower part of the base 4 , and a photoelectric sensor is arranged inside the level 301 ; each level 301 is electrically connected to the adjacent electromagnet 104 .

[0036] On the basis of the above embodiment, two spirit levels 301 are additionally installed at the lower part of the base 4, so that before the base 4 is fixed on the wall, the two spirit levels 301 can be used to calibrate the placement of the base 4 and assist in positioning the opening position on the wall, without the need to manually detect the levelness during the installation process, and it is convenient to use. After the installation is completed, the spirit level 301 monitors the levelness of the solar controller in real time to prevent the wall of the solar controller from tilting or the fixing bolts from loosening, which may cause the solar controller to tilt and the internal connectors of the solar controller, such as wiring terminals and plugs, etc. Looseness affects the reliability of the electrical connection, and short circuit occurs, leading to spontaneous combustion. At this time, when the spirit level 301 detects that the solar controller is not in a horizontal state, it promptly controls the starting electromagnet 104, and then cooperates with the magnetic block 103, the connecting rod 102 and the retaining ring 105 to pull the wire 001 out of the solar controller, thereby realizing the power-off emergency of the solar controller. After the operator restores the solar controller to a horizontal state and fixes it, the spirit level 301 controls the electromagnet 104 to loosen the magnetic block 103, and then the operator reconnects the wire 001 to the solar controller.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
