What type of heat dissipation takes place when heat flows from the wal

1.	What type of heat dissipation takes place when heat flows from the walls of the cooler to the cooling medium?(a) convection(b) radiation(c) convection and radiation(d) conduction and radiationThe question was posed to me at a job interview.This is a very interesting question from Temperature Rise in Transformers topic in portion Design of Transformers of Design of Electrical Machines
Answer» RIGHT choice is (c) CONVECTION and radiation Explanation: When the HEAT flows from the walls of thecooler to the cooling MEDIUM, it is both convection and radiation. In transformer all 3 types of heat dissipation occurs.
