The utility model provides a technical scheme is: a radiator comprises a core assembly consisting of radiating tubes and radiating strips, wherein water chambers are arranged at two ends of the core assembly, the end parts of all the radiating tubes extend into water cavities in the water chambers, a main board sleeved and fixedly installed on all the radiating tubes is arranged on the core assembly, clamping plates bent towards the direction of the water chambers are arranged on the periphery of the main board, and clamping holes are formed in the clamping plates;

an annular sealing gasket is arranged between the main board and the water chamber, and a plurality of buckles matched with the clamping holes are convexly arranged on the outer wall of the periphery of the water chamber.

As an improvement, the outer wall of the water chamber is provided with a plurality of reinforcing ribs which are arranged in a transversely-longitudinally staggered mode, the buckles are arranged in one-to-one correspondence with the reinforcing ribs, and the buckles are integrally formed on the reinforcing ribs and clamped at the ends for suspension.

As a further improvement, mutually-matched stepped structures are arranged on the sides, abutted to the sealing gasket, of the water chambers, and an annularly-extending groove is formed in the side, abutted to the main board, of the sealing gasket.

Adopted the aforesaid technical scheme, the utility model provides a beneficial effect of radiator as follows:

the radiator comprises a core assembly consisting of radiating tubes and radiating strips, water chambers are arranged at two ends of the core assembly, end parts of all the radiating tubes extend into water cavities in the water chambers, a main board which is sleeved and fixedly installed on all the radiating tubes is arranged on the core assembly, clamping plates bent towards the direction of the water chambers are arranged on the periphery of the main board, and clamping holes are formed in the clamping plates; an annular sealing gasket is arranged between the main board and the water chamber, and a plurality of buckles matched with the clamping holes are convexly arranged on the outer wall around the water chamber, so that the main board is fixedly arranged on the core subassembly firstly in the assembling process of the radiator, and then the assembly of the water chamber on the core subassembly is completed through the clamping matching of the clamping holes on the clamping board and the buckles on the water chamber; meanwhile, the assembling structure is simplified, the assembly is convenient, and the assembly efficiency is improved.

Because be equipped with a plurality of strengthening ribs of violently indulging crisscross setting on the outer wall of hydroecium, buckle and strengthening rib one-to-one set up, the buckle integrated into one piece on the strengthening rib, and clamp the end suspension to not only promote the overall structure intensity of hydroecium through the strengthening rib, with buckle integrated into one piece, also promoted the structural strength of buckle moreover, simple structure, the shaping is convenient, arrange rationally.

Because the hydroecium all is equipped with the echelonment structure of mutual adaptation with sealed one side that offsets of filling up, and sealed one side that offsets with the mainboard of filling up is equipped with the recess that the annular extends to the echelonment structure and the recess of mutually supporting make hydroecium and sealed fill up between, fill up and form multistage sealed cooperation between the mainboard, promoted sealed effect greatly.
