<p>Provided is a heat exchanger that, by optimising fin thickness, achieves an excellent cooling effect while having excellent workability. The disclosed heat exchanger (1) is mounted on equipment used on construction sites and cools heated coolant. The heat exchanger (1) is provided with a tube (21) that coolant flows into, and a fin (25) that is connected to the tube (21) and has an imperforated, flat heat radiating surface. The thickness of the fin (25) is set greater than 0.2 mm and up to 0.4 mm. Further, aluminium is selected as the material of the tube (21) and the fin (25) and aluminium solder is used to join the tube (21) and the fin (25) to each other.</p> |
