The core of the utility model is to provide a kind of radiator, can be that lamps and lanterns radiate, avoid lamps and lanterns in the course of work In damaged since operating temperature is higher.Another core of the utility model is to provide a kind of lamp with above-mentioned radiator Tool is not easy to damage since operating temperature is high, and service life is longer.
It please refers to Fig.1 and Fig. 2, Fig. 1 is light source provided by the utility model and radiator installation is complete schematic diagram;Figure 2 be the vertical view of rear heat dissipation plate provided by the utility model.
The utility model provides a kind of radiator, includes the preceding heat dissipation plate 5 being fitted and connected for the substrate 6 with light source 4, Side of the preceding heat dissipation plate 5 far from light source 4 is equipped with heat-dissipating pipe 2, and 2 inside of heat-dissipating pipe is filled with coolant liquid 10.
Specifically, the light source 4 for illumination such as spotlight is usually provided with substrate 6, packaged light source 4 on substrate 6, and according to Actual demand selectively installs the concentration structures such as convex lens 7 in 4 front end of light source, realizes the illumination functions of lamps and lanterns.
Preceding heat dissipation plate 5 is that weldering can be used for being fitted and connected with substrate 6 in platy structure between preceding heat dissipation plate 5 and substrate 6 It the modes such as connects to be fixed.Lamps and lanterns will produce the powerful light-emitting device such as heat, especially spotlight in lighting process, The temperature of lamps and lanterns is usually higher after work a period of time, and the luminous heat generated of light source 4 can pass through substrate 6 and conduct to preceding heat dissipation plate 5。
The surface of preceding heat dissipation plate 5 is provided with heat-dissipating pipe 2, and end or periphery and the preceding heat dissipation plate 5 of heat-dissipating pipe 2 are welded and fixed. Coolant liquid 10 inside heat-dissipating pipe 2 can absorb the heat in environment, and wherein coolant liquid 10 can select the mixed of water and ethylene glycol Close liquid or the strong substance of other heat absorption capacities.It should be understood that after since coolant liquid 10 is absorbed heat during the work time, volume It will increase and possibly even vaporize, therefore coolant liquid 10 should reserve the space of expanded by heating in filling, avoid inside heat-dissipating pipe 2 Heat-dissipating pipe 2 caused by pressure is excessive damages.
Preceding heat dissipation plate 5 is arranged in the utility model on the substrate 6 of light source 4, the 2 inside filling of heat-dissipating pipe on preceding heat dissipation plate 5 There is coolant liquid 10.When light source 4, which illuminates, generates heat, coolant liquid 10 absorbs the heat on environment and preceding heat dissipation plate 5, is dropped for lamps and lanterns Temperature.
Optionally, 2 one end of heat-dissipating pipe is fixedly connected with preceding heat dissipation plate 5, and the other end is fixedly connected with rear heat dissipation plate 1, and after Heat dissipation plate 1 is spaced pre-determined distance with preceding heat dissipation plate 5.
The homonymy in substrate 6 is arranged in preceding heat dissipation plate 5 and rear heat dissipation plate 1, and the two has the equally spaced pre-determined distances of 50mm, It should be noted that pre-determined distance, 5 thickness of preceding heat dissipation plate and 1 thickness of rear heat dissipation plate should be chosen according to practical radiating requirements. The both ends of same heat-dissipating pipe 2 are fixedly connected with preceding heat dissipation plate 5 and rear heat dissipation plate 1 respectively, i.e. the height and pre-determined distance of heat-dissipating pipe 2 It is consistent.The setting of heat dissipation plate 1 plays the role of enhancing 2 stability of heat-dissipating pipe afterwards.
Further, for the heat-sinking capability of intensifier, the edge or rear scattered of the end of heat-dissipating pipe 2 and preceding heat dissipation plate 5 The edge of hot plate 1 connects, and the middle part of the middle part of preceding heat dissipation plate 5 and rear heat dissipation plate 1 is connected by fin 3.
Specifically, the end of 2 side of each heat-dissipating pipe, along the circumferentially distributed of preceding heat dissipation plate 5, the end of the other side is dissipated along rear Hot plate 1 it is circumferentially distributed;The space interior that each heat-dissipating pipe 2 surrounds be equipped with fin 3, and the both ends of fin 3 respectively with preceding heat dissipation Disk 5 and rear heat dissipation plate 1 are welded and fixed.3 The concrete specification of fin is subject to actual demand, is less than 1.5mm, mutually for example, by using thickness Fin 3 structure of the interval less than 2mm.
During the work time, fin 3 is connected with preceding heat dissipation plate 5, and the heat of preceding heat dissipation plate 5 is conducted to fin 3, fin 3 setting increases heat exchange area, to improve heat exchange amount and radiating efficiency.And the both ends of fin 3 using the above structure It is in stationary state, the high stability of fin 3.
