[0019] As Figs. 1-3The utility model discloses technical scheme provides a kind of flat field concave grating heat dissipation support device, including support, positioning assembly being set on the support, fixed component and heat dissipation component.The support includes support base plate 1, support part 2 being set around the support base plate 1 and being connected with the support base plate 1, and mounting portion 8 being installed outside the support part 2, the support surface 3 height of the support part 2 is higher than the end surface height of the support base plate 1;Heat dissipation through slot 4 is provided on the support part 2, the heat dissipation component is installed in the heat dissipation through slot 4, and the heat dissipation component is in contact with grating 13 bottom.

[0020] Grating 13 (refers to ordinary concave grating, same below) when using on spectrum and equipment, because each element generates certain heat in use, leading to grating temperature is higher, thus using heat dissipation support to install grating, can be in certain extent to grating and carry out heat dissipation, guarantee grating use stability and prolong service life.In the above scheme, grating is placed on support part 2, and bottom is supported by support end 3, and the contact area of support surface 3 and grating bottom is small, avoid local heat to release, and there is gap between grating after supporting and support base plate 1, guarantee heat better circulation, and heat dissipation component is in contact with grating bottom in heat dissipation through slot 4, under the action of heat conduction, heat on grating will be transferred to heat dissipation component, finally realize the heat dissipation of grating component, and heat dissipation component uses high thermal conductivity material, such as aluminum, copper etc..Generally, spectrum equipment is equipped with fan lamp heat dissipation structure, and heat generated by heat dissipation component can be carried away under the action of heat dissipation structure.

[0021] Grating 13 both sides are provided with positioning block 9, and the positioning block 9 is detachably connected with the positioning assembly, and the positioning assembly includes positioning slot 10, and when grating is fixed, the positioning block 9 is inserted into the positioning slot 10.When the positioning block 9 on both sides of grating is inserted into two positioning slots 10, it indicates that grating position is placed accurately, and then grating side is fixed by fixed component.

[0022] The heat dissipation component includes connecting rod 5 and a plurality of heat-conducting sheets 6 being spaced apart on the connecting rod 5, and the heat-conducting sheets 6 are in contact with the bottom surface of the grating.
