Abstract: This disclosure provides a series connected water cooling structure. Each water cooling head includes a housing, and the housing includes a water inlet and a water outlet. The connecting pipes are connected between the water cooling heads to be in a series manner. The connecting pipes are connected to the water inlets of adjacent water cooling heads to configure the series connected water cooling heads. The water-inlet pipe and the water-outlet pipe are connected to the water inlet and water outlet of the series connected water cooling heads respectively. The water-inlet pump and the water-outlet pump are arranged on the water-inlet pipe and the water-outlet pipe respectively. Therefore, the heat dissipation efficiency is improved.

Abstract: A plug-in pump installation structure of a cooling distribution unit is disclosed. A pump seat is disposed in a machine case and has a fixed joint. A plug-in pump has a pump main body and a moveable joint. The plug-in pump is plugged or removed relative to the pump seat through the moveable joint and the fixed joint being connected or released. One distal end of each rotary arm of a handgrip has a latching hook. The rotary arms are pivotally connected at opposite sides of the pump main body. When the handgrip is folded on the machine case, the latching hook abuts against a protrusion disposed on a block piece of the machine case, when the handgrip is rotated to be away from the machine case, the latching hooks of the rotary arm is released from the abutted protrusion.

Abstract: A server with a vibration sensing function includes a cooling fan (10), a vibration sensing module (20) and a computing module (30). The vibration sensing module (20) is disposed in the server and is physically coupled to the cooling fan (10). The vibration sensing module (20) obtains a monitoring value that is updated continuously by detecting a vibration of the cooling fan (10). When the vibration sensing module (20) confirms that the monitoring value matches a threshold value, the vibration sensing module (20) outputs a warning message. The computing module (30) receives the monitoring values and the warning message.

Abstract: A cooling device having a centrifugal pump directly mounted on a radiator. An annular seal member is disposed between the bottom portion of the case body of the centrifugal pump and the side surface of the tank chamber of the radiator, and the annular seal member is used for preventing the cooling medium leakage via a space between the centrifugal pump and the tank chamber. The cylindrical portion of the case body and the annular seal member are overlapped with each other in the axial direction of the rotation center shaft of the motor that drives the centrifugal pump, in order that the cylindrical portion can receive at least a part of the reaction force of the annular seal member crushed between the case body and the tank chamber, and thereby the bottom portion of the case body of the centrifugal pump is prevented from deformation.

Abstract: In the cooling device, an annular seal member (38) for preventing the leakage of the cooling medium from a space between the centrifugal pump (6) and the tank chamber (11) is disposed between the bottom portion (23d) of the case body (23) of the centrifugal pump (6) formed in a bottomed cylindrical shape which has a cylindrical portion (23c) and a bottom portion (23d) and the tank chamber (11) of the radiator (4). Further, in the cooling device, an inner peripheral surface (23r) of the cylindrical portion (23c) connected to a surface of the bottom portion (23d) on a side in an X2 direction overlaps the seal member (38) when seen in an axial direction of a rotation center shaft (30) of a motor (15).

Abstract: A fixing frame for a heat sink includes boards, at least one foldable plate, and connection members. The boards surround a hollow area, and the hollow area includes a main accommodating space and at least one subsidiary accommodating space at one side of the main accommodating space. At least one foldable plate is detachably connected to one of the boards and is disposed in the subsidiary accommodating space. The connection members are disposed on the boards. By means of the connection members, the fixing frame mounts the heat sink on a circuit board of various sizes to dissipate heat therefrom.

Abstract: An adjustable fastening bracket used in a radiator includes a supporting stand which includes a plate body provided with pluralities of combination grooves, each combination groove includes a through hole and a long through groove, at least one side of the long through groove away from the through hole is provided with at least one positioning recess; pluralities of positioning elements, each of which includes a positioning plate and a pair of elastic arms, a penetrating hole is provided on the positioning plate corresponding to the through hole, each elastic arm has a positioning convex part; pluralities of fixing elements, each of which penetrates the penetrating hole and the through hole to be disposed in each combination groove, and each fixing element drives the pair of elastic arms to make the positioning convex part of the pair of the elastic arms clip into any one of the positioning recesses.

Abstract: A fastening positioning device for a handle of a power supply, including: a power supply having a rectangular outer case; a handle structured from upper and lower arms and a grip; a spring piece; a clasp groove defined on a side surface of the outer case, which enables the protruding portion to clasp therein; shaft pins that respectively penetrate the shaft holes and into the respective pivot joint holes defined in the surfaces of the outer case; whereby the handle is firmly positioned on the outer case without the worry that application of an inappropriate external force will cause malposition of the handle on the outer case, and protruding bulk of the handle positioned to the outer case is considerably reduced.
