the utility model provides a be applied to welding-free support bar of plate-fin heat exchanger, includes support bar body and two threaded rods, this internal chamber that subtracts of support bar, and the outer wall of support bar body both sides all welds there is the fixed plate, two the spout has all been opened to fixed plate one side outer wall, and both sides all are equipped with the mount about the support bar body, two the mount both ends all are fixed with the slider, and two sliders inlay the dress respectively in two spouts.
Preferably, the inner walls of the upper side and the lower side of the weight reducing cavity are both fixed with connecting plates, and the outer wall of one side, opposite to the two connecting plates, is provided with a supporting plate.
Preferably, two the outer wall of the opposite side of the fixing frame is all bonded with anti-skid pads, and anti-skid threads are arranged on the two anti-skid pads.
Preferably, two through holes are formed in the two ends, far away from the outer wall of one side, of the fixing frame, and nuts are screwed at the two ends of the two threaded rods.
Preferably, the two fixing frames are of C-shaped structures, and the two connecting plates and the supporting plate form I-shaped structures.
The utility model has the beneficial effects that:
1. the support bar body is fixed by inserting the threaded rod into the through holes of the upper fixing frame and the lower fixing frame, screwing nuts at two ends of the threaded rod, and clamping the main body of the plate-fin heat exchanger by the two fixing frames, so that the support bar body is free from being welded and fixed, convenient to detach and convenient to later overhaul;
2. through setting up subtract the weight that the weight chamber can alleviate the support bar body, the transport of being convenient for through "worker" style of calligraphy structure that two connecting plates that set up and backup pad formed, can ensure the structural strength of support bar body, greatly reduced the probability that produces mechanical deformation, increase of service life.
