Preferably, the height of the positioning column is lower than the depth of the positioning groove.

Compared with the prior art, the utility model discloses a radiator location closure anchor clamps has following beneficial effect:

the positioning grooves are arranged to be matched with the limiting blocks, so that the positioning of the radiating fins and the radiating base can be realized, the hinged limiting blocks can be opened after being locked, the radiating base can be conveniently taken out, and the feasibility of separating the positioning mechanism from the locking mechanism is realized;

the split structure ensures that only the C-shaped locking pieces on the two sides are arranged when the jig is fed into the reflow furnace, so that the jig does not absorb more heat when passing through the reflow furnace, the welding requirement of the product can be met by using a lower furnace temperature, and the energy utilization efficiency is improved;

in addition, the positioning base can be taken out before entering the reflow furnace, so that the positioning base can be conveniently rotated to a front end installation work station for recycling, the quantity demand on the positioning base is not too much, and the comprehensive cost of the jig is reduced;

therefore, the utility model discloses an anchor clamps not only realize energy saving and emission reduction more reduction in production cost also promote efficiency simultaneously, the effectual product competitiveness that has promoted.
