Title:
HEAT EXCHANGER AND METHOD FOR PRODUCING SAME, AND SANITARY WASHING APPARATUS PROVIDED WITH HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2013/114846
Kind Code:
A1
Abstract:
This heat exchanger is provided with: a casing comprising a first flow path forming member (21) and a second flow path forming member (22), which are provided with flow path ribs on at least one inner wall surface; and a flat plate-like heater (20) enclosed inside the casing. Furthermore, the heat exchanger has: recessed main flow paths (25) formed by the flow path ribs and flat plate-like heater (20); and leakage flow paths (41) formed by the gaps between the upper surfaces of the flow path ribs and the surfaces of the flat plate-like heater (20). The leakage flow path (41) gaps are from 0.05 mm to 15 mm. A heat exchanger that prevents the generation of local boiling of washing water at the surfaces of the flat plate-like heater (20), and has excellent stable heat exchanging performance and scaling resistance can thus be achieved.
