I think on the no. of diodes there must be some changes in the rate of heat transfer, but how kindly explain. Also provide the colling technique for such electronic devices.
Every electronic components have there own characteristics to generate heat. It depends on how the accurate device is, what is the interfacing, what is material used etc. Simultaneously it depends on no. of components used.

Dear Kumar
I hope, might help you.

Dear Ashwini,
I would like to add to the collages above that any electronic device including diodes have electrical ratings which are the current and the voltage that can be applied safely on the device. For a diode as a swishing device, it dissipates energy and converts it into heat during the on period, the off period and the transition from the on and off states. which is called the dynamic loss. All theses losses will cause the diode temperature to rise against the ambient temperature. One defines the so called maximum operating temperature of the diode at which there will be a corresponding dissipated power. If the operating power is larger than the nominal power one has to apply forced cooling on the diode.
As the diode operating current is increased its area must be increase to limit its operating temperature under the allowed value.
If the current required in the circuit is greater than that of the rated value of a specific diode , then one can connect diodes in parallel to increase the global current carried by the diodes. The other solution one can choose a larger diode that can carry safely the current.
Choosing one strong diode is better than choosing a group of smaller diodes performing the same function. One diode will be reliable than the equivalent group of diodes. It will be also economical.
You can utilize such solution of smaller equivalent diodes when you do not have the strong diode.
Best wishes
