Abstract
The utility model discloses a radiator for a high temperature circuit, comprising a heating source and a radiator, wherein the radiator is closely connected with the heating source. The radiator is characterized in that the radiator is internally provided with n S-shaped radiating air ducts; air inlets of the S-shaped radiating air ducts are communicated with a cooling air source; and outlets are communicated with the outside. The utility model has the advantages that the radiating of the heating source is uniform and sufficient, a driving circuit board of the heating source is ensured to be dry, and the service life of the heating source is prolonged.
Description
Technical field
The utility model belongs to a kind of radiator, relates to a kind of high temperature circuit radiator specifically.
Background technology
Can be in the circuit elements device course of work by certain electric current, especially powerful components and parts work long hours and can heating elevate the temperature, and burn out circuit easily, reduce the useful life of components and parts.Therefore, need to adopt cooling measure to reduce the temperature of components and parts.In pyrotoxins such as CPU, high-powered LED lamp group, adopt the blower fan heat radiation at present, as shown in Figure 1 and Figure 2, radiator is overlayed on the pyrotoxins such as circuit board of CPU or high-powered LED lamp group, and closely connect with it, on radiator, stack blower fan again, blower fan is directly aimed at radiator blowing heat radiation, cooling radiator, and the heat of pyrotoxin taken away.But under this radiating mode, the wind direction both sides that blower fan is produced by boasting disperse, and cause the middle part of chip or circuit board to form the heat radiation blind area, and it is insufficient to dispel the heat, and influences their useful life.
The defective of prior art is: in air-cooled heat radiation circuit, cooling air often can only be to the neighboring area heat radiation of heater element or heating circuit, can't be to the middle section heat radiation of pyrotoxin, just form the heat radiation blind area easily, and this blind area highest temperature point of pyrotoxin often that dispels the heat, because heat radiation is inhomogeneous, influenced the useful life of pyrotoxin.
The utility model content
The purpose of this utility model is to provide a kind of high temperature circuit radiator, can eliminate the heat radiation blind area, makes the full and uniform heat radiation of pyrotoxin.
The technical solution of the utility model is as follows: a kind of high temperature circuit radiator, include pyrotoxin and radiator, radiator closely is connected with pyrotoxin, its key is: have n bar S type heat dissipation wind channel in the described radiator, the import of S type heat dissipation wind channel communicates with the cooling wind regime, and outlet communicates with the external world.
Described n is the natural number greater than 1.S type heat dissipation channel can guarantee the even inswept pyrotoxin of cooling air of coming in from import and the entire contact surface of radiator, makes the entire contact surface heat radiation evenly, does not have the heat radiation blind area, and pyrotoxin can fully dispel the heat.
The outlet of described S type heat dissipation wind channel communicates with dry channel, and the drive circuit board of pyrotoxin is installed in dry channel.
Wind is mobile in the dry channel, and drive circuit board is kept dry.
Described cooling wind regime is a blower fan.
Described pyrotoxin is the high-powered LED lamp group.
Described pyrotoxin is an integrated circuit (IC) chip.
Remarkable result of the present utility model is: can not only make whole pyrotoxin heat radiation evenly fully, can also keep the drying of pyrotoxin drive circuit board, the useful life of having improved pyrotoxin and drive circuit.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1:
Shown in Fig. 3,4, a kind of high temperature circuit radiator, include pyrotoxin 1 and radiator 2, described pyrotoxin 1 is the high-powered LED lamp group, radiator 2 closely is connected with pyrotoxin 1, have n bar S type heat dissipation wind channel 3 in the described radiator 2, the import of S type heat dissipation wind channel 3 communicates with cooling wind regime 4, and outlet communicates with the external world.
The outlet of described S type heat dissipation wind channel 3 communicates with dry channel 5, and the drive circuit board 6 of pyrotoxin 1 is installed in dry channel 5.
Described cooling wind regime 4 is a blower fan.
Its working condition is as follows:
Can generate heat during pyrotoxin 1 work, cause pyrotoxin 1 higher with the contact-making surface temperature of radiator 2, cooling wind regime 4 produces the import that cooling air enters S type heat dissipation channel 3, all contact-making surfaces of even inswept pyrotoxin 1 of this cooling air and radiator 2, and enter dry channel 5 to the external world from outlet, in this process, cooling air is taken away the heat of contact-making surface, make the contact-making surface heat radiation evenly, thereby guarantee that pyrotoxin 1 fully dispels the heat, eliminated the heat radiation blind area a that occurs in the existing design, cooling air is in the process of dry channel 5 of flowing through simultaneously, dry drive circuit board 6, thus useful life of pyrotoxin 1 prolonged.
Embodiment 2:
As shown in Figure 5, the structure of present embodiment and operation principle and embodiment 1 are roughly the same, and its difference is: described pyrotoxin 1 is integrated circuit (IC) chip, and this circuit chip fits tightly the bottom surface at radiator 2.
