Abstract
The utility model discloses a non-fan special computer with fin radiation comprising a case composed of a U shaped aluminum upper cover plate with fins, a front faceplate, a rear faceplate and a lower cover plate. The U shaped aluminum upper cover plate with fins is fixedly connected to a mainboard, radiating fins jointly connect the mainboard and the U shaped aluminum upper cover plate with fins and are arranged between the two above. The non-fan special computer with fin radiation of the utility model has good radiation ability and strong anti-vibration ability.
Description
Technical field
The utility model relates to a kind of no fan special computer, and relating in particular to a kind of fin heat dissipation type does not have the fan special computer.
Background technology
Special computer is being collectively referred to as of military and industrial computer, and it generally works in the abominable place of high temperature, high humidity, high vibrations and high dust.Now just develop towards miniaturization, multifunction and high frequency direction.Present special computer generally all adopts no fan design, promptly adopt the combination of finned shell and heat radiator to dispel the heat, can save the body internal fan like this and produce the needed space of convection current, saved the electric energy of original fan, need not the window better tightness of dispelling the heat simultaneously, and eliminated noise fully.Existing heat radiator is that a kind of two sides is to be the device of heat pipe in the middle of the plate heat conduction material.Its one side contacts with the electronic package surface, and another side contacts with outer casing inner wall, and nationality conducts to finned shell with the heat that electronic package is produced, and by the air of outside convection current heat is dissipated to surrounding environment from the fin surface.
The computing machine that the combination of finned shell of existing employing and heat radiator is dispelled the heat, its typical structure is that computer motherboard is installed on the cabinet lower cover, finned heat-dissipating casing comprises upper cover plate and left side plate, one end of heat radiator contacts with the components and parts on the computer motherboard, the other end contacts with the upper cover plate or the left side plate of heat-dissipating casing, there is following problem in this mode: if heat radiator will be fitted on the upper cover plate inwall, because of upper cover plate is to close at last, the distance of itself and heat radiator is difficult to control on machining precision, easy excesssive gap between upper cover plate and the heat radiator, cause the heat-conducting cream of needs blocked up, influence radiating efficiency; If heat radiator contacts with the shell left side plate, there is tolerance clearance between upper cover plate and the left and right sides plate like this, because the heat transfer efficiency of air is very low, the existence meeting of air produces very big obstacle to the conduction of heat in the gap, heat radiator just can't dispel the heat by whole finned shell, thereby the complete machine radiating efficiency is reduced; In addition, by screw retention, do not have screw retention with the cabinet other parts between general of heat radiator and the mainboard, in the strong environment of vibration, because of the density of metal fin own is bigger, and the mechanical strength of mainboard is limited, so screw is loosening easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of perfect heat-dissipating, fin heat dissipation type that vibration resistance is strong not to have the fan special computer.
The utility model solves above-mentioned technical matters by the following technical programs: a kind of fin heat dissipation type does not have the fan special computer, comprise shell, shell is made up of finned U-shaped aluminium upper cover plate, front panel, rear panel and lower cover, finned U-shaped aluminium upper cover plate is fixedly connected with mainboard, is provided with the heat radiator that is fitted and connected with the two between mainboard and the finned U-shaped aluminium upper cover plate.
Heat radiator is fixed on the finned U-shaped aluminium upper cover plate top inner wall.
Heat sink top surface and finned U-shaped aluminium upper cover plate internal face form fit, the two fits tightly.
Heat radiator underrun heat-conducting cream and mainboard are fitted and connected, and by screw retention, the heater members on the mainboard dispels the heat by heat radiator.
Mainboard passes through four jiaos screw retention on finned U-shaped aluminium upper cover plate top inner wall.
Mainboard is fixed on the inwall of finned U-shaped aluminium upper cover plate both sides by installing plate.
The utility model is that the finned upper cover plate of original shell and left and right sides plate are designed to incorporate finned U-shaped aluminium upper cover plate, heat radiator and mainboard reversal of the natural order of things are fixed on the U-shaped heat-dissipating casing inwall, rather than common being installed on the cabinet lower cover, compare with present no fan type special computer, heat radiator directly is fixedly connected on the U-shaped heat sink end face inwall, the two is fitted as far as possible, and the space between them just can control to minimum; The U-shaped upper cover plate of being made of one of the finned part of shell, rather than be divided into upper cover plate and left and right sides plate three parts, so just, avoided the generation in gap between three parts, made the heat of heater members on the mainboard derive the radiating efficiency height from whole finned U-shaped aluminium upper cover plate; Heat radiator directly is fixed on the better metal shell of physical strength by screw, rather than only is fixed on the mainboard, and resistance to shock is better.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that the utility model embodiment heat radiator and mainboard are inverted the structural representation that is installed on the finned U-shaped aluminium upper cover plate.
Embodiment
As Fig. 1, shown in 2, a kind of fin heat dissipation type does not have the fan special computer, comprise shell, shell is by finned U-shaped aluminium upper cover plate 1, front panel 6, rear panel 8 is formed with lower cover 7, finned U-shaped aluminium upper cover plate 1 internal fixation is connected with mainboard 3, mainboard 3 is fixed on finned U-shaped aluminium upper cover plate 1 top inner wall by four jiaos screw 5, be provided with and the two heat radiator that is fitted and connected 2 between mainboard 3 and the finned U-shaped aluminium upper cover plate 1, heat radiator 2 also is fixed on finned U-shaped aluminium upper cover plate 1 top inner wall, heat radiator 2 end faces and finned U-shaped aluminium upper cover plate 1 internal face form fit, the two fits tightly, heat radiator 2 underrun heat-conducting creams and mainboard 3 are fitted and connected, heater members is by heat radiator 2 heat radiations on the mainboard 3, mainboard 3 can also be fixed on the finned U-shaped aluminium upper cover plate 1 both sides inwall by installing plate, fits tightly as long as guarantee mainboard 3 and heat radiator 2.
Installation steps are:
1. finned U-shaped aluminium upper cover plate is inverted;
