Document Type and Number:
WIPO Patent Application WO/2011/055656
Kind Code:
A1
Abstract:
Provided is a heat exchanger which can inhibit increase in pressure loss and raise heat-exchange performance. The heat exchanger (1) includes a plurality of plate-shaped fins (21) attached around the outer circumferences of heating pipes (20) in which a refrigerant flows, and exchanges heat with air. Three lines of heating pipes (20a, 20b, 20c) are disposed along the direction in which the air flows. The inlet-side heating pipe from among the three lines of heating pipes (20a, 20b, 20c) which may be used as an evaporator, or the outlet-side heating pipe from among the three lines of heating pipes (20a, 20b, 20c) which may be used as a condenser, has the smallest diameter. If the heating pipe on the most windward side has the smallest diameter, D1 < D2 = D3, 4 mm ≤ D3 ≤ 10 mm, and 0.6 ≤ D1 / D3 < 1, wherein D1 denotes the pipe diameter of the heating pipe on the most windward side, D2 denotes the pipe diameter of the heating pipe in the center, and D3 denotes the pipe diameter on the most leeward side. If the heating pipe on the most leeward side has the smallest diameter, D1 < D2 = D3, 4 mm ≤ D3 ≤ 10 mm, and 0.6 ≤ D1 / D3 < 1, wherein D1 denotes the pipe diameter of the heating pipe on the most leeward side, D2 denotes the pipe diameter of the heating pipe in the center, and D3 denotes the pipe diameter on the most windward side.
