The heat dissipation fins and the heat transfer part 42 are made of high thermal conductivity material, in this embodiment, the heat transfer part 42 is a heat pipe, and the connection manner between the heat dissipation fins and the heat pipe may be welding or other connection manners with low contact thermal resistance. The arrangement positions of the heat pipes need to cover the side walls of the hard disk modules, and the heat of the hard disks corresponding to the side walls of the hard disk modules is collected together and then conducted to the heat dissipation fins, so that the temperature uniformity of all the hard disks corresponding to the side walls of the hard disk modules can be improved.

The system fan module (not shown) is composed of a fan, a fan frame and a fan control module. The system fan provides cooling air volume for the whole, the fan frame fixes the fan, and the fan control module mainly receives system instructions to control the rotating speed of the fan, so that the purposes of energy conservation and noise reduction are achieved. The embodiment adopts a PWM speed regulation mode.

One specific heat dissipation process is as follows:

besides radiation, the hard disk heat dissipation mode has two ways of forced convection heat dissipation: firstly, a gap between an upper hard disk and a lower hard disk can form a forced convection air channel, and a system fan is used for air draft and heat dissipation, namely direct heat dissipation; and secondly, the hard disk is contacted with the hard disk frame module through the hard disk box, and heat can be transferred to the hard disk frame side plate. The whole hard disk frame side plate can be used as a radiator of a corresponding hard disk and has the temperature equalizing function. The heat pipes of the hard disk frame heat dissipation module are embedded in the hard disk frame side plates, the heat pipes are arranged on the corresponding side walls of the hard disks, and meanwhile, the heat conduction paths of the hard disks connected with the hard disk frame side plates are communicated, so that the uniformity of the temperature between the upper hard disk and the lower hard disk can be better improved. The heat pipe transfers the heat in the side plate of the hard disk frame to the radiating fins, and finally the cooling air provided by the system fan takes away the heat, namely indirect heat radiation.

As shown in fig. 6-9, an efficient hard disk heat dissipation system is provided, which includes a heat dissipation air inlet 2, a hard disk frame module 3, a hard disk frame heat dissipation module, and a system fan module (not shown).

At least one of the hard disk frame side plates which are arranged oppositely also comprises a hard disk side wall elastic sheet 7. The hard disk fixing panel 6 is connected with the chassis or the hard disk frame side plate, and may adopt a screw connection or other clamping connection modes, which is not limited herein. The hard disk fixing panel 6 is provided with a system air inlet, and optionally, a hard disk module fixing structure is further fixed on the hard disk fixing panel to provide a function of limiting the front and back movement of the hard disk module. The hard disk side wall elastic sheet 7 is connected with the hard disk frame side plate 31 on one side, the other side is well attached to the hard disk module side wall of the hard disk 5 without a gap, a good heat conduction environment is formed, and meanwhile, the function of limiting the movement of the hard disk 5 in the left and right directions is provided. The hard disk side wall elastic sheet 7 is made of a high thermal conductivity material, and may be a copper sheet or other high thermal conductivity materials, which are not limited herein. The area of the hard disk side wall elastic sheet 7 covers the side wall of the hard disk module of the hard disk 5, so that the heat conduction area is maximized. The hard disk side wall elastic sheet 7 has certain elasticity, and can clamp the hard disk 5 to avoid a contact gap between the hard disk 5 and the hard disk.

One specific heat dissipation process is as follows:

besides radiation, the hard disk heat dissipation mode has two ways of forced convection heat dissipation: firstly, a gap between an upper hard disk 5 and a lower hard disk 5 can form a forced convection air channel, system cooling air pumped by a system air cooling heat dissipation module enters a high-efficiency hard disk heat dissipation system from a system air inlet of a hard disk fixing panel 6, and air is drawn by a system fan for heat dissipation, namely, direct heat dissipation is realized; secondly, hard disk 5 conducts the heat to hard disk frame curb plate 31 through hard disk lateral wall shell fragment 7, and whole hard disk frame curb plate 31 can regard as the radiator that corresponds hard disk 5, has the samming effect simultaneously concurrently. The heat transfer component 42 in the hard disk frame heat dissipation module is embedded in the hard disk frame side plate 31, the heat transfer component 42 is arranged in the corresponding hard disk side plate 31, and meanwhile, the heat conduction paths of 4 hard disks (4 hard disk modules are taken as an example in fig. 8, but actually not limited to 4 hard disk modules) connected with the hard disk frame side plate are communicated, so that the uniformity of the temperature between the upper hard disk module and the lower hard disk module can be better improved. The heat transfer component 42 transfers heat in the hard disk frame side plate 31 to the heat dissipation component 41, and finally, cold air provided by a system fan takes away the heat, namely, indirect heat dissipation.

As shown in fig. 10, the high-efficiency heat dissipating system further includes a strong cooling heat dissipating module 43, such as a strong cooling fan. The strong cooling fan is only controlled by the temperature of the hard disk, and when the temperature of the hard disk is too high, the strong cooling fan assists the system fan to strengthen the heat dissipation of the hard disk together. The strong cooling fan is started at two times: firstly, when a system fan of the system air-cooling heat dissipation module reaches the maximum rotating speed and the temperature of the hard disk is still higher and is not reduced obviously, the strong cooling fan is started at the moment in order to further reduce the temperature of the hard disk; and secondly, when the temperature of the hard disk reaches a certain threshold value, the forced cooling fan is started, and the hard disk is cooled by the forced cooling fan and the system fan of the system air-cooling heat dissipation module. Therefore, the system fan with higher rotating speed and larger noise can be avoided, and the heat dissipation capacity of the hard disk can be further improved. The forced cooling fan can be placed at the air inlet of the radiating fin of the radiating assembly 41 to perform air blowing cooling on the radiating fin, and can also be placed at the air outlet of the radiating fin to perform air draft cooling on the radiating fin. Fig. 10 shows induced draft cooling, and both induced draft cooling and forced draft cooling may be specifically adopted, and this embodiment is not particularly limited.

One specific heat dissipation process is as follows:

besides radiation, the hard disk heat dissipation mode has two ways of forced convection heat dissipation: firstly, a gap between an upper hard disk 5 and a lower hard disk 5 can form a forced convection air channel, system cooling air enters equipment from an air inlet of a hard disk fixing panel 6, and air suction and heat dissipation are carried out by a system fan, namely direct heat dissipation is carried out; secondly, hard disk 5 conducts the heat to hard disk frame curb plate 31 through hard disk lateral wall shell fragment 7, and whole hard disk frame curb plate 31 can regard as the radiator that corresponds hard disk 5, has the samming effect simultaneously concurrently. Heat transfer components 42 in the hard disk frame heat dissipation module are embedded in the hard disk frame side plates 31, the heat transfer components 42 are arranged in the corresponding hard disk side plates 31, and meanwhile, heat transfer paths of 4 hard disks connected with the hard disk frame side plates are communicated, so that the uniformity of the temperature between the upper hard disk and the lower hard disk can be better improved. The heat transfer member 42 transfers heat in the hard disk frame side plate 31 to the heat radiation fins. When the temperature of the hard disk reaches a certain threshold value, the strong cooling fan is started, and the heat dissipation of the hard disk is accelerated together with the system fan. Finally, cooling air provided by the system fan and the strong cooling fan takes away heat, namely indirect heat dissipation.
