Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cooling, in particular to a circuit board cooling device. Background Art

[0002] Circuit boards are important electronic components, supporting bodies for electronic components, and carriers for electrical connections between electronic components. Because they are made using electronic printing technology, they are called "printed" circuit boards. During the production process of circuit boards, the temperature of the circuit boards may be too high, so they need to be cooled, otherwise they will cause damage to the circuit boards.

[0003] According to a circuit board cooling device provided by application number CN219960956U, a first pipe is arranged on one side of the shell, the first pipe movably passes through one side of the shell and extends to the outside to be fixedly connected with a connector, and a second pipe is arranged on one side of the bracket, and the bracket is a cavity structure, a plurality of card slots are arranged on the bracket, and air holes are arranged in the middle of the card slots. When the card slots on the bracket are full of circuit boards, the bracket is pushed to move toward the inside of the shell until the first pipe and the second pipe are connected, and the external refrigeration device is started to transport cold air into the bracket, and finally discharged from the air holes on the bracket, so that the adjacent circuit boards placed in the card slots can be cooled, which is beneficial to accelerate the cooling of the circuit boards and facilitate the rapid stacking and placement of the circuit boards.

[0004] However, the following problems still exist in actual use:

[0005] In this document, cold air is transmitted to the inside of the bracket and then acts on the circuit board through the air holes. In this way, since the movement direction of cold air is downward relative to hot air, the amount of cold air acting on the circuit board is relatively reduced. At the same time, this document also uses a fan to blow the cold air further away from the circuit board, so that the cold air cannot effectively contact the circuit board, thereby reducing the cooling efficiency of the circuit board. At the same time, the fan continuously exchanges gas from the outside to the inside of the device. Since the outside air contains a certain amount of impurities, impurities will remain on the circuit board during the cooling process, affecting the subsequent use of the circuit board.

When cooling the circuit board placed in the placement slot provided on the placement board, first, the connecting pipes provided at both ends of the circulation pipe are connected to an external device carrying condensed water, and condensed water is sent into the inside of the circulation pipe through the connecting pipe. When the condensed water enters the inside of the circulation pipe, the temperature around the circulation pipe drops. At this time, the fan works to transport the cold air around the circulation pipe, so that the cold air contacts the circuit board through the flow slot provided on the U-shaped protective frame. Moreover, since the placement board is provided with a slot one and a slot two respectively, and the circuit boards on the placement board are arranged in an orderly manner, the cold air can contact the circuit board completely, thereby taking away the heat contained in the circuit board, so that the circuit board is cooled. The board can be cooled quickly.

At the same time, when the cold air passing through the circuit board collides with the V-shaped guide plate arranged on the inner side of the side door through the notch, the V-shaped guide plate is arranged in a V-shape, thereby diverting the cold air. The diverted air flows from the upper and lower sides of the cooling frame respectively, and passes through the arc-shaped guide plates arranged on the upper and lower sides of the cooling frame, and flows to the rear of the fan, and is reused through the operation of the fan, so that the cold air can be circulated for use, so that an effective cold air circulation is formed inside the cooling frame, without the need for outside air to intervene, thereby reducing the influence of outside air on the circuit board.

[0015] 2. The cooling device for the circuit board is provided with a placement mechanism. When placing the circuit board, the limiting pin inserted in the limiting groove is firstly taken out. At this time, the placement frame is pulled outward. Since the side of the placement frame is rotatably connected with the U-shaped block, and the other side of the U-shaped block is fixedly connected with the sliding block slidably connected to the inside of the sliding frame through the connecting rod, the placement frame can be moved to the outside of the cooling frame. When it moves to a suitable position, the U-shaped plug-in block inserted on the limiting block is pulled out. At this time, the placement frame can be rotated, and the placement board with the circuit board placed thereon is inserted into the insertion groove opened on the inner side of the placement frame through the insertion block. At the same time, the lower surface of the placement board is The upper surface of the pad fixedly connected to the inner wall of the placement frame is fitted, and the placement plates are placed in sequence according to the above method, and then the two groups of placement frames are rotated to the same horizontal line, and the U-shaped plug is inserted again. At this time, the placement frame is pushed into the interior of the cooling frame, and then the limiting pin is inserted into the interior of the corresponding limiting groove, so as to complete the placement of the circuit board. The setting of this structure can effectively place the circuit boards and separate the placed circuit boards so that the circuit boards can better contact the cold air for cooling. The setting of this structure can place more circuit boards, and then can cool down multiple groups of circuit boards at the same time, thereby improving the practicability of the device in actual use.
