In above-mentioned cooler for recycled exhaust gas, the outer side wall of described housing is fixed with fixing frame.
During use, housing is stably linked together by fixing frame and worktable, thus further increases the cooling effect of this cooler for recycled exhaust gas.
Compared with prior art, this cooler for recycled exhaust gas has the following advantages:
1, the path of cooling water is contrary with the path of waste gas, makes the temperature of the cooling water being positioned at air outlet place lower, thus to reduce from air outlet the temperature of waste gas out comparatively significantly, improves the cooling effect of cooler for recycled exhaust gas.
2, water outlet and water outlet lay respectively at the both sides up and down of housing, while guarantee cooling effect, can reduce the use amount of cooling water, thus reduce user cost.
3, waste gas enters from suction port and is distributed in each heat dissipating pipe, thus adds the area of contact between waste gas and cooling water, then improves the cooling effect of this cooler further.
4, by arranging corrugated pipe segment, increasing the area of contact of heat dissipating pipe and cooling water, thus adding the area of contact between waste gas and cooling water, then improving the cooling effect of this cooler further.
