Computing device and hard disk installation frame thereof

The embodiment of the invention discloses computing equipment and a hard disk installation frame thereof. The hard disk mounting frame comprises a hard disk mounting frame and a connector module, the frame is provided with a connector plug-in mounting port, an air passing opening and a mounting part, the connector plug-in mounting port is used for mounting the connector module so as to be adaptively connected with a hard disk to be assembled, and signal transmission is carried out while the hard disk is assembled and fixed; the air passing opening is formed in the frame body in a penetrating manner for air flow to pass through; the frame body can be fixed in the equipment case through the mounting part, and based on the good bearing capacity of the frame body, an air passing opening with the through-flow area capable of meeting the heat dissipation air volume requirement can be formed, so that an air channel for improving the heat dissipation capacity is constructed. Besides, the scheme can adapt to an applic
