Title:
STRUCTURE OF CONTAINER FOR REDUCING AGENT
Document Type and Number:
WIPO Patent Application WO/2005/111387
Kind Code:
A1
Abstract:
On the upper surface of a container body, there are installed at least a base section of a water level meter for detecting the remaining amount of a liquid reducing agent, a base section of a concentration meter for detecting the concentration of the liquid reducing agent, a heat exchanger surrounding each of detection sections of the water level meter and the concentration meter and exchanging heat between an engine coolant and the liquid reducing agent by circulating the engine coolant, and a suction tube provided between the water level gauge and the concentration meter and sucking the liquid reducing agent from the bottom of the container body. A substantially box-like protector is installed so as to surround the water level meter, concentration meter, and suction tube that are positioned at the lower part of the heat exchanger. Heat discharged from the lower part of the heat exchanger is confined inside the protector, and convection is produced in the confined region. By this, the liquid reducing agent frozen around the water level meter, concentration meter, and suction tube is efficiently thawed.
