Description
Technical Field
[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for a frequency converter. Background Art
[0002] The inverter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The inverter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, and microprocessing unit. The inverter adjusts the voltage and frequency of the output power supply by the internal IGBT. During the use of the inverter, a certain amount of heat will be generated, which needs to be dissipated through a heat dissipation device to ensure the normal use of the inverter;
[0003] The existing flat device performs passive heat dissipation through the fins on the outside of the inverter during use. However, this method is limited by the heat conduction efficiency between the inverter and the air. In actual use, the heat on the inverter cannot be efficiently conducted away, resulting in low heat dissipation efficiency, which makes the inverter prone to overheating in summer. Summary of the invention
[0004] In view of the above-mentioned technical deficiencies, the purpose of the utility model is to provide a frequency converter heat dissipation device, which fits the heat conduction plate to the outside of the frequency converter and then uses water to flow through the inside of the waterway to take away the heat, thereby solving the problem of low heat dissipation efficiency.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: The utility model provides a frequency converter heat dissipation device, including: a heat dissipation mechanism, the heat dissipation mechanism includes a heat conducting plate, the outer wall of the heat conducting plate is provided with a water channel, the outer wall of the heat conducting plate is fixedly connected with a sealing cover, the side wall of the sealing cover is installed with a water pump, the water pump is connected with one end of the water channel, the side wall of the sealing cover is fixedly connected with a heat dissipation water tank, the output end of the water pump is connected with the bottom end of the heat dissipation water tank, the top end of the heat dissipation water tank is connected with the other end of the water channel, and the side wall of the heat dissipation water tank is installed with two sets of fans. The heat conducting plate is attached to the outer wall of the frequency converter, and the high thermal conductivity between metals is used to enable the heat on the frequency converter to be efficiently transferred to the heat conducting plate, and then the heat on the heat conducting plate is taken away by the water inside the water channel to prevent the frequency converter from overheating.
[0006] Preferably, the side wall of the sealing cover is slidably connected with two groups of latches extending to the outside of the sealing cover, the ends of the two groups of latches are rotatably connected with a group of connecting rods, and a handle is rotatably connected between the two groups of connecting rods. When the handle is pulled, the two groups of latches can be driven at the same time, which is convenient and quick to operate when the two groups of radiators are connected separately.
[0007] Preferably, the outer wall of the handle is fixedly sleeved with an insulating sleeve, and the bottom end of the sealing cover is fixedly connected with two sets of limiting rings, and the positions of the two sets of limiting rings correspond to the pins. By setting the limiting ring sleeve outside the pin, the two sets of heat dissipation devices can be fixedly connected together.
[0008] Preferably, a return spring is fixedly connected to the side wall of the latch, and the end of the return spring is fixedly connected to the inner wall of the sealing cover. The return spring's resilience prevents the latch from sliding when the handle is not manually pulled, thereby preventing the latch from sliding out of the limiting ring.
[0009] Preferably, the outer wall of the heat conducting plate is fixedly connected with a sealing gasket located beside the water channel, and the sealing cover is tightly fitted with the sealing gasket, so that the sealing performance between the sealing cover and the heat conducting plate is stronger, and water inside the water channel is prevented from leaking out.
[0010] Preferably, the side wall of the heat conducting plate is fixedly connected to a limiting assembly, the limiting assembly includes a fixing block, and the inner wall of each group of the fixing blocks is slidably connected to a group of limiting pins, and the ends of the limiting pins extend to the outside of the fixing block. The limiting blocks block the side wall of the inverter so that the heat conducting plate and the inverter will not separate.
[0011] Preferably, the side wall of the limit pin is fixedly connected with a limit spring located inside the limit block, and the end of the limit spring is fixedly connected to the inner wall of the limit block. Through the resilience of the limit spring, the limit pin will not slide when there is no manual push on the limit pin, so as to prevent the limit pin from being displaced and thus the limit pin cannot be blocked on the side wall of the inverter.
[0012] The beneficial effects of the utility model are:
[0013] The utility model attaches the heat conducting plate to the outer wall of the inverter and utilizes the high thermal conductivity between metals so that the heat on the inverter can be efficiently transferred to the heat conducting plate, and then the heat on the heat conducting plate is taken away by the water inside the waterway, so that the heat can be dissipated more efficiently during the operation of the inverter.
[0014] The utility model inserts a limiting ring on one group of heat dissipation devices into the inside of another group of heat dissipation devices and limits the limiting ring by a latch, so that the two groups of heat dissipation devices can be connected together for use. When facing inverters of different sizes, the heat dissipation devices can be used more flexibly, thereby improving the adaptability of the heat dissipation devices during use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0026] like Figures 1 to 6As shown, this embodiment provides a frequency converter heat dissipation device, including: a heat dissipation mechanism 1, the heat dissipation mechanism 1 includes a heat conducting plate 101, the outer wall of the heat conducting plate 101 is provided with a water channel 103, the outer wall of the heat conducting plate 101 is fixedly connected with a sealing cover 102, the side wall of the sealing cover 102 is installed with a water pump 105, the water pump 105 is connected with one end of the water channel 103, the side wall of the sealing cover 102 is fixedly connected with a heat dissipation water tank 106, the output end of the water pump 105 is connected with the bottom end of the heat dissipation water tank 106, the top end of the heat dissipation water tank 106 is connected with the other end of the water channel 103, two sets of fans 107 are installed on the side wall of the heat dissipation water tank 106, the outer wall of the heat conducting plate 101 is fixedly connected with a sealing gasket 104 located next to the water channel 103, and the sealing cover 102 is tightly fitted with the sealing gasket 104.
[0027] The principle of this embodiment is as follows: the heat conducting plate 101 is sleeved on the outside of the inverter so that the heat generated by the inverter is transferred to the heat conducting plate 101, and then water is injected into the water channel 103 inside the heat conducting plate 101, and the water is driven by the water pump 105 to flow into the heat dissipation water tank 106, and then the fan 107 blows air to pass through the heat dissipation water tank 106, thereby taking away the heat in the water, so that the heat transferred to the heat conducting plate 101 is taken away by the airflow, thereby achieving the effect of cooling the inverter. Example
[0028] like Figures 1 to 6 As shown, on the basis of retaining all the technical features in specific embodiment one (or the difference between this embodiment and specific embodiment one is that), in this embodiment: the side wall of the sealing cover 102 is slidably connected with two groups of pins 108 extending to the outside of the sealing cover 102, the ends of the two groups of pins 108 are respectively rotatably connected with a group of connecting rods 109, a handle 110 is rotatably connected between the two groups of connecting rods 109, the outer wall of the handle 110 is fixedly sleeved with an insulating sleeve, the bottom end of the sealing cover 102 is fixedly connected with two groups of limit rings 111, the positions of the two groups of limit rings 111 correspond to the pins 108, the side wall of the pin 108 is fixedly connected with a reset spring 112, and the end of the reset spring 112 is fixedly connected to the inner wall of the sealing cover 102.
[0029] Principle of this embodiment: pull the handle 110 on the lower heat sink so that the handle 110 drives the two groups of pins 108 to approach each other through the connecting rod 109, thereby compressing the reset spring 112, and insert it into the lower heat sink through the limiting ring 111 on the upper heat sink, so that the limiting ring 111 is inserted into the sealing cover 102, and then release the handle 110 to make the reset spring 112 rebound. At this time, the reset spring 112 pushes the pin 108 to reset, so that the pin 108 is inserted into the limiting ring 111, so the limiting ring 111 cannot slide out from the sealing cover 102 at this time, so that the two groups of heat sinks are connected together. When the two groups of heat sinks need to be separated, the handle 110 is pulled again to make the pin 108 slide out from the limiting ring 111, and the upper heat sink can be pulled apart from the lower heat sink. Example
[0030] like Figure 3 and Figure 4 As shown, on the basis of retaining all the technical features in specific embodiment one and / or embodiment two (or the difference between this embodiment and specific embodiment one and / or embodiment two is that), in this embodiment: the side wall of the heat conducting plate 101 is fixedly connected to the limiting assembly 2, the limiting assembly 2 includes a fixed block 201, and the inner wall of each group of fixed blocks 201 is slidably connected with a group of limiting pins 202, and the ends of the limiting pins 202 extend to the outside of the fixed block 201, and the side walls of the limiting pins 202 are fixedly connected with a limiting spring 203 located inside the limiting block, and the ends of the limiting springs 203 are fixedly connected to the inner wall of the limiting block.
[0031] Principle of this embodiment: the inner wall of the heat conducting plate 101 is provided with a groove that matches the outer wall of the inverter. The groove on the inner wall of the heat conducting plate 101 is aligned with the fin on the outer wall of the inverter, and then the heat conducting plate 101 is pushed to be mounted on the outside of the inverter. The limit pin 202 contacts the outer wall of the inverter, so that the outer wall of the inverter pushes the limit pin 202 to slide inside the fixed block 201. At this time, the limit spring 203 is compressed by the limit pin 202. When the heat conducting plate 101 is completely mounted on the outside of the inverter, the limit pin 202 is no longer pushed by the inverter, so the limit spring 203 rebounds and pushes the limit pin 202 to reset, so that the limit pin 202 is blocked by the inverter, so the heat conducting plate 101 cannot be separated from the inverter.
[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
