Abstract: The present invention relates generally to an automatic cooling/heating control method of an air conditioner for a vehicle. The present invention is intended to propose the control method, wherein instead of controlling indoor temperature via manual manipulation, operation modes set in figurative languages, not temperature, are used so as to automatically control indoor cooling/heating, whereby an atmosphere more pleasant than an atmosphere provided by a conventional method is efficiently provided and manipulation frequency of a console is reduced. To achieve the above objects, the control method includes: selecting an air operation mode desired by a user; starting an initial operation by the air conditioner after determining whether to cool, heat, or fan; setting the indoor temperature according to the outdoor temperature; resetting the set indoor temperature by using a correction value according to present indoor temperature; and operating by setting a reset indoor temperature to be a final set temperature.

Abstract: According to an embodiment of the present disclosure, a method for a fan simulation through flow analysis includes the steps of: inputting point data and tester dimensions by a user; generating a shape of a fan by calculating the point data, and generating a tester from the tester dimensions; generating grids on the fan; analyzing a flow generated by the fan by inputting boundary conditions for the fan; and calculating a noise index from the analysis, wherein, when the flow generated by the fan is in a steady state, the noise index is proportional to a pressure deviation depending on a location of the fan.

Abstract: Disclosed is a bent-type dissipater, including one or a plurality of heat sinks which are adapted with cooling apertures; one or a plurality of cooling pins which are bent in structure, and which are integrated to the heat sinks, and a central heat passage for combining heat moving in one direction with ambient air, and discharging the heat in the opposite direction.

Abstract: An LED module with a cooling passage is disclosed. The LED module includes a light source unit having a plurality of LED's which provide light through an appropriate power supply, and one or more cooling units which form said cooling passage, which combine heat generated from the LEDs with ambient heat and discharges the combined heat in an opposite direction.
