Meanwhile, in the hard disk cartridge 100 of the embodiment of the present application, the first heat conducting member 140 is further disposed, at least a portion of the first heat conducting member 140 abuts against the housing 110, and the housing 110 is at least used for dissipating heat transferred by the first heat conducting member 140, so that the first heat conducting member 140 can conduct out another portion of heat generated by the circuit board 120 and the hard disk 210 during operation to the housing 110, and the housing 110 dissipates heat. Therefore, the hard disk cartridge 100 of the embodiment of the application can combine the active heat dissipation in the housing 110 by matching the heat dissipation fan 130, the air inlet portion 111 and the air outlet portion 112 with the passive heat dissipation in the housing 110 by matching the first heat conduction member 140 and the housing 110, so that the heat dissipation capacity of the hard disk cartridge 100 is improved, the difficulty of timely dissipating heat of the heat in the hard disk cartridge 100 is reduced, and the occurrence probability of situations such as speed reduction, data transmission blocking and the like of the hard disk cartridge 100 in operation is also reduced.

In one embodiment, the mounting location 121 includes a first clamping portion 1211 disposed on the circuit board 120, where the first clamping portion 1211 is used to clamp the second clamping portion 220 on top of the hard disk 210, so as to simplify the connection between the circuit board 120 and the hard disk 210 and improve the stability of the hard disk 210 placed on the mounting location 121.

In the embodiment in which the circuit board 120 and the cooling fan 130 are both disposed perpendicular to the horizontal plane, the main control chip is located above the first heat conducting member 140, which is beneficial to reducing the space enclosed by the housing 110 and the side of the circuit board 120 facing the cooling fan 130.

As shown in fig. 1, 3 and 4, in one embodiment, an interface 123 for establishing an electrical connection with an electronic device is provided on the top of the circuit board 120, and a display port 116 capable of exposing the interface 123 is provided at a position corresponding to the interface 123 of the housing 110. The circuit board 120 may be an adapter board capable of performing interface conversion and protocol conversion, and the interface 123 may be ase:Sub>A Type-C interface or ase:Sub>A USB-ase:Sub>A interface, so as to convert an m.2 interface of the hard disk 210 into ase:Sub>A Type-C interface or ase:Sub>A USB-ase:Sub>A interface, and convert satase:Sub>A protocol or NVME protocol of the hard disk 210 into ase:Sub>A USB3.0 protocol, so as to facilitate datase:Sub>A communication with the electronic device.

Meanwhile, the outer side wall of the interface 123 protruding out of the housing 110 may be made of a heat conducting material, and the outer side wall of the interface 123 is arranged to contact with the housing 110, so that heat generated by the circuit board 120 can be taken away by air flow generated and driven by the cooling fan 130, and can be conducted to the housing 110 by the first heat conducting element 140, and can be transferred to the housing 110 through the outer side wall of the interface 123, and heat in the housing 110 is diffused through three paths, so that the heat dissipation speed of the heat in the housing 110 is increased, and the heat dissipation effect is improved.

As shown in fig. 1, as an embodiment, the housing 110 is provided with a first air hole 113 and a second air hole 114, one of the first air hole 113 and the second air hole 114 forms an air inlet portion 111, and the other forms an air outlet portion 112. For example, when the air flows into the housing 110 from the first air holes 113, the heat dissipation fan 130 drives the air to flow on the surface of the circuit board 120 in the housing 110 during operation, and then flows out of the housing 110 through the second air holes 114 to take out heat in the housing 110. For another example, when the air flow enters from the second air hole 114, the heat dissipation fan 130 drives the air flow to flow on the surface of the circuit board 120 in the housing 110 during the operation, and then flows out of the housing 110 through the first air hole 113 to take out the heat in the housing 110. The first air holes 113 are disposed opposite to the heat dissipation fan 130, and at least a portion of the second air holes 114 are disposed opposite to a gap formed between the heat dissipation fan 130 and the circuit board 120. In this way, when the air flow enters the housing 110 from the second air hole 114, the air flow may flow through the side of the circuit board 120 facing the heat dissipation fan 130, or the air flow flowing into the housing 110 may flow out of the second air hole 114 from a gap formed between the heat dissipation fan 130 and the circuit board 120. Thus, the area of the airflow flowing through the circuit board 120 is enlarged, and the heat dissipation effect on the circuit board 120 is improved.

As shown in fig. 1, in the embodiment in which the circuit board 120 and the heat dissipation fan 130 are both disposed perpendicular to the horizontal plane, the first air hole 113 is disposed opposite to the left side surface of the heat dissipation fan 130, and the second air hole 114 is disposed opposite to the front side surface of the heat dissipation fan 130, so that the first air hole 113 and the second air hole 114 are disposed on the adjacent two sides of the housing 110 to increase the path of the air flow flowing in the housing 110, thereby improving the heat dissipation effect. The number of the first air holes 113 is a plurality, and the first air holes 113 are arranged to form a grid shape, so that when the air flow enters the housing 110 from the first air holes 113, part of dust entrained with the air flow can be blocked, thereby improving the cleanliness in the housing 110. The number of the second air holes 114 is also a plurality, and the plurality of second air holes 114 are arranged in at least one row, such as one row, two rows or three rows, and the number of rows formed by the second air holes 114 is not limited in this embodiment.
