Heat dissipating element for radiator and method of manufacturing therefor

A radiator for cooling a device, the device having a fluid flowing therethrough to extract heat therefrom, the radiator comprising:

• a first collector pipe for connection with the device to be cooled to receive the fluid therefrom;
• a second collector pipe for connection with the device to be cooled to supply back the fluid thereto;
• and
• one or more heat dissipating elements, wherein each of the one or more heat dissipating elements comprises:
• a body having a top portion, a bottom portion and a middle portion;
• a plurality of flutes defined in the body, with each of the plurality of flutes providing a single continuous channel to allow for flow of the fluid therein;
• an inlet port provided at the top portion in fluid communication with the first collector pipe to receive the fluid therefrom, and to supply the fluid to each of the plurality of flutes;
• and
• an outlet port provided at the bottom portion to collect the fluid from each of the plurality of flutes, and in fluid communication with the second collector pipe to supply the collected fluid thereto,
• wherein a cross-section of each one of the plurality of flutes has a hexagonal profile, formed of two trapeziums mirrored to each other along bases thereof;
• and
• wherein each of the plurality of flutes extend longitudinally downwards and diverge laterally outwards from the inlet port in the top portion of the body, extend longitudinally downwards in the middle portion of the body, and extend longitudinally downwards and converge laterally inwards towards the outlet port in the bottom portion of the body,
• wherein the cross-section of each flute is constant along an entire longitudinal length of the flute from the inlet port to the outlet port.

A method of manufacturing a heat dissipating element for a radiator, the method comprising:

• forming a first metal sheet to define a plurality of first open profiles extending along a longitudinal length thereof;
• forming a second metal sheet to define a plurality of second open profiles extending along a longitudinal length thereof, complementary to the plurality of predefined open profiles formed in the first metal sheet;
• joining the first metal sheet and the second metal sheet so as to form a body having a top portion, a bottom portion and a middle portion, and a plurality of flutes defined therein from the plurality of first open profiles and the plurality of second open profiles closing each other, with each of the plurality of flutes providing a single continuous channel to allow for flow of a fluid therein;
• providing an inlet port at the top portion of the body to receive the fluid and supply the fluid to each of the plurality of flutes;
• and
• providing an outlet port at the bottom portion of the body to collect the fluid from each of the plurality of flutes,
• wherein each of the plurality of first open profiles and each of the plurality of second open profiles is in form of a trapezium opened at base thereof, and wherein a cross-section of each one of the plurality of flutes is in the form of two trapeziums mirrored to each other along the bases thereof;
• and
• wherein each of the plurality of flutes extend longitudinally downwards and diverge laterally outwards from the inlet port in the top portion of the body, extend longitudinally downwards in the middle portion of the body, and extend longitudinally downwards and converge laterally inwards towards the outlet port in the bottom portion of the body,
• wherein the cross-section of each flute is constant along an entire longitudinal length of the flute from the inlet port to the outlet port.
