The heating problem of LED street lamp is little more a lot of than ordinary lamps, generally carries no weight.But along with the continuous development of high-power LED street lamp, its reliability requirement also improves constantly, and the heat dissipation problem of LED street lamp also becomes the focus that people pay close attention to gradually.The radiating mode of LED street lamp mainly contains heat-conducting plate mode, finned mode, installs fan forced heat radiation mode and loop heat pipe radiating mode etc. additional at present, every kind of radiating mode cuts both ways, and wherein the loop heat pipe radiator is a kind of advanced person's a radiating mode.But loop heat pipe radiator of the prior art normally processes the passage of the hole of different shape as radiator in copper coin, and its difficulty of processing is big, Heavy Weight, and the cost height causes the loop heat pipe radiator not to be used widely in LED street lamp field.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, ingenious, rational, be applicable to the radiator on the high-power LED street lamp, this radiator process for machining and manufacturing is simple, and material is thin, and is light and handy and firm, product cost is low, the heat transfer efficiency height.
According to technical scheme provided by the invention: a kind of high-power LED street lamp radiator is characterized in that: comprise housing, offer refrigerant inlet on a side of housing, offer refrigerant outlet on another opposite flank of housing; Radiating fin is installed in housing, offers coolant channel in the radiating fin.
As a further improvement on the present invention, described housing comprises upper plate, lower shoe and strip of paper used for sealing, and four strip of paper used for sealings connect and compose a rectangle frame, is connected with tongue-and-groove by tenon between two adjacent strip of paper used for sealings; Upper plate, lower shoe are contained in respectively on the upper and lower surface of rectangle frame, constitute the housing of a sealing; Described refrigerant inlet is opened on the strip of paper used for sealing, and refrigerant outlet is opened on another strip of paper used for sealing of opposite side.
As a further improvement on the present invention, clamped metal partion (metp) respectively between the rectangle frame that described upper plate, lower shoe and strip of paper used for sealing constitute.
As a further improvement on the present invention, be coated with the heat conductive insulating ceramic layer on the outer surface of described lower shoe.
As a further improvement on the present invention, the surface of described radiating fin is a zigzag structure.
As a further improvement on the present invention, described refrigerant inlet has two, and two refrigerant inlet are symmetrically distributed in the two-end part of its side, place; Described refrigerant outlet has one, and refrigerant outlet is positioned at the centre of its side, place.
As a further improvement on the present invention, described radiating fin adopts the aluminum material punching press to make.
Adopt soldering to make it to become an integral body attractive in appearance between all parts.
The present invention compared with prior art, advantage is: simple in structure, ingenious, reasonable, process for machining and manufacturing is simple, material is thin, and is light and handy and firmly, product cost is low, the heat transfer efficiency height.
Description of drawings
Fig. 1 is the three-dimensional view of frontal of the present invention.
Fig. 2 is the three-dimensional view of the back side of the present invention direction.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the present invention is a kind of radiator that is applied on the high-power LED street lamp, and it mainly is made up of parts such as strip of paper used for sealing 2, metal partion (metp) 3, lower shoe 4, radiating fin 5, upper plates 8.
As shown in Figure 1 and Figure 2, upper plate 8, lower shoe 4, strip of paper used for sealing 2 and metal partion (metp) 3 are formed the housing of a sealing, and four strip of paper used for sealings 2 connect and compose a rectangle frame, are connected with tongue-and-groove 6 by tenon 7 between two adjacent strip of paper used for sealings 2; Upper plate 8, lower shoe 4 are contained in respectively on the upper and lower surface of rectangle frame, and two metal partion (metp)s 3 are installed in respectively between the rectangle frame of upper plate 8, lower shoe 4 and strip of paper used for sealing 2 formations.
As shown in Figure 1 and Figure 2, on a strip of paper used for sealing 2, offer refrigerant inlet 1, on another strip of paper used for sealing 2 of opposite side, offer refrigerant outlet 9; Radiating fin 5 is installed in the described housing, offers coolant channel in the radiating fin 5.During work, cold-producing medium enters from refrigerant inlet 1, flows through and fully flows out from refrigerant outlet 9 after the heat exchange again from radiating fin 5 inside.
As shown in Figure 1 and Figure 2, be coated with the heat conductive insulating ceramic layer on the outer surface of described lower shoe 4, promptly insulation has good heat-conducting effect again.The surface of described radiating fin 5 is a zigzag structure, can improve the radiating efficiency of radiating fin 5 greatly.
As shown in Figure 1 and Figure 2, described refrigerant inlet 1 has two, and two refrigerant inlet 1 are symmetrically distributed in the two-end part of its side, place; Described refrigerant outlet 9 has one, and refrigerant outlet 9 is positioned at the centre of its side, place.Two advance a design that outes can make the flow field of radiator more even, and radiating efficiency is higher.
The housing of radiator of the present invention is assembled by several parts, and the manufacturing process difficulty is little.Radiating fin 5 adopts the aluminum material punching press to make.Adopt soldering to make it to become an integral body attractive in appearance between all parts.The entire radiator quality is light and handy and firm.
