Abstract
A showcase having a fin-and-tube type cooler includes planar fins and a refrigerant pipe penetrating through the planar fins. The planar fins include long fins arranged in parallel to an air flow direction through the cooler, and short fins shorter in length than the long fins and arranged between adjacent long fins at a downstream side of the cooler. The refrigerant pipe includes first U-shaped hair pins having two straight pipe portions, and second U-shaped hair pins having two straight pipe portions. The pitch between the two straight pipe portions of each second U-shaped hair pin is set to double the pitch between the two straight pipe portions of each first U-shaped hair pin. The first and second U-shaped hair pins penetrate through the hole portions formed in the plural planar fins so as to be arranged in a predetermined style.
