Description
Technical field
The utility model relates to radiator, relates in particular to the LED radiator of the help led chip heat radiation that is applied in the LED light fixture.
Background technique
The LED light fixture is a kind of with light-emitting diode chip for backlight unit, and promptly led chip is as the light fixture of light-emitting component.This light fixture is necessary for led chip and is equipped with radiator.Existing LED radiator does not mostly possess the function that used heat utilizes.
The model utility content
The purpose of the utility model provides a kind of LED radiator that adopts hot machine heat radiation, and this radiator can be realized the effect that used heat utilizes.
The utility model is achieved in that a kind of LED radiator that adopts the heat radiation of hot machine, and said LED radiator is an external heating motor, this external heating motor with liquid as working medium; Liquid refrigerant is contained in the container; Container is provided with the heat-absorbing chamber wall with the led chip thermo-contact, and led chip constitutes the outer thermal source of said external heating motor, and container is communicated with the cavity of a piston cylinder and vacuumizes; Liquid refrigerant is heated, and steam that gasification produces can get into piston cylinder and the piston that promotes in the piston cylinder moves; End away from container of piston cylinder is provided with the heat release casing wall that contacts with low-temperature receiver, and the steam that the liquid refrigerant gasification produces can promote the position that piston moves to heat release casing wall place, and behind this position condensation liquefaction, flows back to container; Piston is connected with a crank through connecting rod, constitutes connecting rod.
The working principle of the LED radiator of the hot machine heat radiation of above-mentioned employing is that the liquid refrigerant in the container absorbs the heat that led chip sends, liquid refrigerant gasification generation steam; The promotion piston moves, and when piston moved to the position at heat release casing wall place, container was flowed back in vapour condensation liquefaction; The piston cylinder internal pressure reduces, the piston travelling backwards, and the steam in the cause piston cylinder leaves the position at heat release casing wall place; So the vapor tension in the piston cylinder begins again to increase, steam promotes piston once more and moves, and so goes round and begins again; Piston is to-and-fro motion constantly, and piston drives crank through connecting rod and rotates continuously, thereby the heat that led chip is produced converts mechanical energy into.
The utility model has the advantages that and have the considerable energy saving environmental benefit.

Fig. 2 is the schematic representation that piston is in top dead center position;
Fig. 3 is the schematic representation that piston is in bottom dead center position.
Embodiment
Referring to Fig. 1, adopting the LED radiator of hot machine heat radiation is an external heating motor, and this external heating motor has a container 1, and liquid refrigerant 2 is housed in the container 1.Liquid refrigerant 2 can adopt liquid such as water, acetone or ether.Container 1 is provided with and the heat-absorbing chamber wall 4 of led chip 3 thermo-contacts (among the figure with a square frame abstract representation led chip).Led chip 3 constitutes the outer thermal source of external heating motor.The form of thermo-contact has multiple, comprises direct contact and the mediate contact through heat transfer medium, can also be the heat-absorbing chamber wall 4 that directly constitutes container 1 with the aluminium base of led chip.Upper fixed at container 1 has a piston cylinder 5, and container 1 is communicated with the cavity of piston cylinder 5 and vacuumizes.Liquid refrigerant 2 is heated, and steam that gasification produces can get into piston cylinder 5 and the pistons 6 that promote in the piston cylinder 5 move up.End away from container 1 of piston cylinder 5 is provided with the heat release casing wall 7 that contacts with low-temperature receiver.Present embodiment as low-temperature receiver, is provided with radiating fin 12 with normal temperature environment on heat release casing wall 7.The steam that liquid refrigerant 2 gasifications produce can promote the position that piston 6 moves to heat release casing wall 7 places, and is as shown in Figure 2.After moving to position shown in Figure 2 on the piston, container 1 is flowed back in vapour condensation liquefaction, and the vapor tension in the piston cylinder 5 reduces, and orders about piston 6 and is moved downward to lower dead center, and is as shown in Figure 3.Piston 6 moves to after bottom dead center, because the steams in the piston cylinder 5 are away from the position at heat release casing wall 7 places, so vapor tension begins again to increase, and steam promotes piston 6 once more and moves up, and so goes round and begins again to make piston 6 to-and-fro motion constantly.Piston 6 is connected with crank 9 through connecting rod 8.Pistons reciprocating 6 drives crank 9 through connecting rod 8 and rotates continuously, thereby the heat that led chip 3 is produced converts mechanical energy into.The crank 9 of present embodiment is a flywheel.
The crank 9 of external heating motor can connect impeller, is rotated by crank 9 impeller.Impeller can be towards led chip 3 blowings or towards other device that need dispel the heat blowings.If impeller though can reduce the mechanical energy output power of the utility model, can play the effect that used heat utilizes towards led chip 3 blowings equally.
