A cooling unit for electronic devices includes a partition board, a heat exchanger, and a blower. The partition board is disposed on one of a plurality of surfaces of an electronic device so as to partition the inner and the outer side of the electronic device. The heat exchanger is disposed on the outer side so as to exchange heat generated by the electronic device with outside air. The blower is disposed on the outer side. The partition board has a first vent and a second vent. The heat exchanger includes hot-air passage bodies and air pathways. The hot-air passage bodies include a plurality of air passages arranged side by side at predetermined intervals in such a manner as to connect the first vent and the second vent on the outer side. The air pathways are formed between adjacent ones of the air passages so as to allow the outside air to pass through the air pathways. The blower blows air of the inner side from the first vent to the second vent through the hot-air passage bodies.
