Description

Technical Field

[0001] The present application relates to the technical field of heat dissipation of charging piles, and specifically to a heat dissipation frame for a charging pile circuit board. Background Art

[0002] When a high-power car charging pile is in use, the heat generated by the charging pile is also large due to its large current. At this time, it is necessary to start the fan to blow air to dissipate heat from the circuit board of the charging pile. In the prior art, an infrared camera or a temperature sensor is usually used to monitor the temperature of the circuit board. When the infrared camera detects that the temperature of the circuit board is too high, the power of the exhaust fan will increase, and the air intake of the charging pile will be increased to quickly dissipate the heat for the circuit board.

[0003] However, since there are many electrical components on the circuit board and the heat generated by different electrical components is inconsistent, if the overall heat dissipation of the circuit board is only achieved by increasing the air intake, the local heat dissipation capacity of the heating area on the circuit board will be poor, which will affect the overall working performance of the charging pile. Summary of the invention

[0004] The present application provides a charging pile circuit board heat dissipation rack, which adjusts the contact position and contact amount between cold air and the local circuit board by changing the position of the blowing nozzle, thereby achieving local rapid heat dissipation of the charging pile circuit board, which can effectively solve the problems in the background technology.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. This charging pile circuit board heat sink adjusts the contact position and amount between the cold air and the local circuit board by changing the position of the blowing nozzle, thereby realizing local rapid heat dissipation of the charging pile circuit board, effectively improving the heat dissipation efficiency of the entire charging pile;

[0014] 2. Cold air is blown onto the upper and lower surfaces of the circuit board through the strip-shaped air blowing nozzle, so that the circuit board can be quickly cooled down.

[0022] See also Figure 1-4 The present application provides the following technical solutions: a charging pile circuit board heat dissipation rack, comprising a fixing plate 6; at least one mounting plate 3 is installed on the outer side of the fixing plate 6, and at least one metal mounting seat 2 is provided on the upper surface of the mounting plate 3; a strip-shaped air blowing nozzle 5 with an air outlet facing the mounting plate 3 is slidably connected to the outer side of the fixing plate 6, and an electrically controlled telescopic rod 9 is provided between the outer side of the strip-shaped air blowing nozzle 5 and the fixing plate 6.

[0023] Specifically, cold air is blown onto the upper and lower surfaces of the circuit board through the strip-shaped air blowing nozzle 5, thereby quickly cooling the circuit board. The electrically controlled telescopic rod 9 can control the lifting and lowering of the strip-shaped air blowing nozzle 5 by extending and retracting, thereby regulating the flow rate of cold air sweeping over the upper and lower surfaces of the circuit board. When the temperature of the upper surface of the circuit board rises abnormally, the strip-shaped air blowing nozzle 5 moves upward.

[0024] The upper end of the inner side of the strip blowing nozzle 5 is rotatably connected with a wind direction adjusting plate 7, the outer side of the strip blowing nozzle 5 is provided with a power mechanism 4 for controlling the rotation of the wind direction adjusting plate 7, and the air inlet end of the strip blowing nozzle 5 is connected with a flexible guide tube 13.

[0025] Specifically, the wind direction adjustment plate 7 can control the direction of the airflow blown out through the air blowing nozzle 5 by rotating, so that the cold air directly contacts the local heating area of ​​the circuit board, thereby improving the heat dissipation efficiency of the circuit board.

[0026] Furthermore, a metal base 8 is provided at the lower end of the outer side surface of the metal mounting seat 2 , and metal heat dissipation plates 1 are evenly distributed in an array on the metal base 8 .

[0027] Specifically, the metal mounting seat 2 and the metal base 8 have high thermal conductivity, and the heat exchange efficiency is increased by the provision of the metal heat sink 1 .

[0028] Furthermore, a cold air inlet 12 is installed on the lower end surface of the flexible guide tube 13 .

[0029] Specifically, the cold air inlet 12 is used to be connected to the air outlet of an external refrigeration unit.

[0030] Furthermore, the flexible guide tube 13 is a silicone tube, and the outer surface of the silicone tube is provided with corrugations.

[0031] Specifically, the provision of the silicone bellows increases the adjustability of the flexible flow guide tube 13 .

[0032] Furthermore, a slider 11 is connected to the outer side of the strip-shaped air blowing nozzle 5 , and the slider 11 is slidably connected to a slide rail 10 arranged on the fixed plate 6 .

[0033] Specifically, the arrangement of the slider 11 enables the strip-shaped air blowing nozzle 5 to be easily adjusted up and down.

[0034] Furthermore, the power mechanism 4 includes a protective cover 42, which is slidably connected to a slider 43 via a slide rail 42 arranged on its inner side, a rack is installed on the slider 43, and the slider 43 is connected to the inner side of the protective cover 42 via an electrically controlled telescopic rod 41. A positioning shaft 45 is installed at the end of the wind direction adjustment plate 7, and a gear 44 is sleeved on the positioning shaft 45, and the gear 44 is meshed with the rack.

[0035] Specifically, the electrically controlled telescopic rod 41 can drive the rack to do reciprocating motion by telescoping, the reciprocating rack can drive the gear 44 to rotate, the rotating gear 44 can drive the positioning shaft 45 to rotate, and the positioning shaft 45 can drive the wind direction adjustment plate 7 to do pitch adjustment.

[0036] During use: the circuit board of the charging pile is installed on the metal mounting base 2. When the charging pile is working, cold air enters the strip blowing nozzle 5 through the flexible guide tube 13. The temperature of the upper and lower surfaces of the circuit board is detected by the infrared temperature sensor installed inside the charging pile. When the temperature of the upper surface of the circuit board is too high, the electric control telescopic rod 9 drives the strip blowing nozzle 5 to move upward, so that most of the cold air blown out through the strip blowing nozzle 5 passes through the upper surface of the circuit board.

[0037] When the infrared temperature sensor detects that the local temperature on the upper surface of the circuit board is too high, the power mechanism 4 drives the wind direction adjustment plate 7 to rotate to adjust the direction of the cold air blown out through the strip blowing nozzle 5, so that most of the cold air can be blown directly to the local high temperature area on the circuit board, thereby improving the heat dissipation efficiency of the circuit board.
