Engine heat balancing performance bed tester and engine heat balancing performance bed testing method

The invention provides an engine heat balancing performance bed tester and an engine heat balancing performance bed testing method, which belong to the field of engine heat balancing technology. The tester provided by the invention comprises an engine bed system, an external cooler and a signal feedback controller; the external cooler is used for cooling built-in cooling devices of a currently tested engine; the signal feedback controller is used for presetting an engine temperature threshold and testing time, monitoring the temperature of the currently tested engine in real time, ordering the engine bed system to control the external cooler to regulate the cooling speed of the built-in cooling devices of the currently tested engine when the temperature of the currently tested engine reaches the preset engine temperature threshold and evaluating the heat balancing performance of the currently tested engine according to the temperature data of the currently tested engine within the testing time. The testing scheme provided by the invention can conveniently and efficiently carry out real-time on-line tests on the engine heat balancing performance of automobiles.
