Radiator with heat dissipation pieces connected in series

A radiator comprising:

• a plurality of heat dissipating pieces secured together in series by a connection device, each of the heat dissipating pieces comprising upper and lower bending edges, each of the heat dissipating pieces including at least one groove, the groove formed by a bending piece having an end bent towards the plane of the bending edges of a respective one of the heat dissipating pieces;
• and
• the connection device comprising at least one insert having a series of spaced apart ditches and inserted through the grooves of adjacent ones of the heat dissipating pieces such that respective ones of the ends of the bending pieces are locked into corresponding ones of the ditches of the insert to secure the heat dissipating pieces in a series.
