Heating radiator

The utility model discloses a heating radiator, which comprises a plurality of heat dissipation unit bodies, wherein the heat dissipation unit bodies comprise two heat dissipation tubes, wherein a tubular sheet head is connected between the end portions of the two heat dissipation tubes which are transversely penetrated, the heat dissipation unit bodies are orderly connected through the tubular sheet head, and the tubular sheet head forms a tubular inlet-outlet channel after connecting. The heating radiator comprises a plurality of heat dissipation unit bodies, and can increase and reduce thenumber of unit bodies according to the demands of different heat dissipating capacity, thereby meeting steel type radiators with different heat dissipating capacity. The inlet-outlet channel is arranged between round heat dissipation tubes, the inner opening is big after penetrating connection, the resistance is reduced, and the heat medium through flow is smooth, thereby increasing the radiatingeffect and the heat energy
