Radiator and Plant Illumination Lamp
A radiator and a plant illumination lamp containing the radiator. The radiator includes a heat-radiating baseplate configured for fixing a heat source, and heat-radiating side plates connected to the heat-radiating baseplate. The heat-radiating side plates each are provided with a plurality of heat-exchanging through grooves running through the heat-radiating side plates. The heat-exchanging through groove forms a heat potential difference, so that under the influence of the heat potential difference, the cold air outside the radiator passes through the heat-exchanging through groove on the heat-radiating side plates, and then flows out through a hot air chamber and an air outlet at an upper end of the hot air chamber after exchanging heat with the heat-exchanging through groove on the heat-radiating side plates, so as to form a strong natural air convection.
1 . A radiator, comprising: a heat-radiating baseplate configured for fixing a heat source, and heat-radiating side plates connected to the heat-radiating baseplate, wherein each heat-radiating side plates is provided with a plurality of heat-exchanging through grooves running through the each heat-radiating side plate.
2 . The radiator according to claim 1 , wherein the heat-radiating side plates are arranged on two sides of the heat-radiating baseplate; and the each heat-radiating side plate is provided with a plurality of heat-radiating fins.
3 . The radiator according to claim 2 , wherein the plurality of heat-radiating fins are integrally formed on the each heat-radiating side plate by a punching method, and after being punched, the heat-radiating side plates are configured with torn portions caused by punching and through-groove portions in a one-to-one correspondence with the torn portions; and the torn portions form the plurality of heat-radiating fins, and the through-groove portions form the heat-exchanging through grooves.
4 . The radiator according to claim 2 , wherein the plurality of heat-radiating fins protrude from the heat-radiating side plates, and the heat exchange through grooves are formed between the heat-radiating side plates and the plurality of heat-radiating fins.
5 . The radiator according to claim 2 , wherein among the plurality of heat-radiating fins, a part of the heat-radiating fins protrude inwardly from the heat-radiating side plates, and another part of the heat-radiating fins protrude outwardly from the heat-radiating side plates.
6 . The radiator according claim 2 , wherein each heat-radiating fin comprises a fin bottom located in a middle and extending straightly, and a fin slanted plate portion extending obliquely from both ends of the fin bottom; one end of the fin slanted plate portion away from the fin bottom is connected to the heat-radiating side plates; and the fin bottom is in a flat plate shape or an arc plate shape.
7 . The radiator according to claim 1 , wherein when the radiator is used for a lamp, the heat-radiating baseplate is integrally provided with a reflector; and the heat-radiating baseplate and the reflector constitute a lamp housing of the lamp and form a light source cavity for the lamp.
8 . The radiator according to claim 1 , wherein the heat-radiating side plates are integrally connected to the heat-radiating baseplate, and the radiator is an extruded aluminum profile or a bent plate.
9 . A plant illumination lamp, comprising: a lamp housing having a light source cavity, a light source mounted in the lamp housing and located in the light source cavity, and the radiator of claim 1 , and the radiator is mounted at an upper end of the lamp housing.
10 . The plant illumination lamp according to claim 9 , wherein the lamp housing and the radiator are in an integral structure; the lamp housing and the radiator share the heat-radiating baseplate; and the light source is mounted on the heat-radiating baseplate.
11 . The radiator according claim 3 , wherein each heat-radiating fin comprises a fin bottom located in a middle and extending straightly, and a fin slanted plate portion extending obliquely from both ends of the fin bottom; one end of the fin slanted plate portion away from the fin bottom is connected to the heat-radiating side plates; and the fin bottom is in a flat plate shape or an arc plate shape.
12 . The radiator according claim 4 , wherein each heat-radiating fin comprises a fin bottom located in a middle and extending straightly, and a fin slanted plate portion extending obliquely from both ends of the fin bottom; one end of the fin slanted plate portion away from the fin bottom is connected to the heat-radiating side plates; and the fin bottom is in a flat plate shape or an arc plate shape.
13 . The radiator according claim 5 , wherein each heat-radiating fin comprises a fin bottom located in a middle and extending straightly, and a fin slanted plate portion extending obliquely from both ends of the fin bottom; one end of the fin slanted plate portion away from the fin bottom is connected to the heat-radiating side plates; and the fin bottom is in a flat plate shape or an arc plate shape.
14 . The radiator according to claim 7 , wherein the heat-radiating side plates are integrally connected to the heat-radiating baseplate, and the radiator is an extruded aluminum profile or a bent plate.
