Multiple-input multiple-output antenna apparatus and heat dissipation device therefor

A massive multiple-input multiple-output (MIMO) antenna apparatus, comprising:

• a board having at least one board surface that holds a distributed arrangement of a plurality of heat-generating components, that has a width and a length, wherein the length is longer than the width, and that includes a first section having a first amount of heat generation and a second section having a second amount of heat generation greater than the first amount of heat generation, the first section and the second section being partitioned along a length direction of the board;
• a first blowing unit disposed to overlap at least some of the first section and configured to cool at least some of heat generated from the first section, the first blowing unit comprising at least one or more first fans;
• a second blowing unit disposed to overlap at least some of the second section and configured to cool at least some of heat generated from the second section, the second blowing unit comprising at least one or more second fans;
• and
• a control unit configured to adjust the airflow discharged from the first blowing unit and the airflow discharged from the second blowing unit,
• wherein the second blowing unit is configured to discharge an airflow greater than the airflow that the first blowing unit is configured to discharge, and
• wherein the control unit is configured to determine how many of the at least one or more first fans are to operate and how many of the at least one or more second fans are to operate based on at least one of a temperature of the first section and a temperature of the second section.
