Title:
LIQUID HEATER FOR USE IN ANALYZER
Document Type and Number:
WIPO Patent Application WO/2017/193989
Kind Code:
A1
Abstract:
A liquid heater (6) for use in an analyzer, comprising a heating element (602) and at least a first liquid receiving chamber (604) and a second liquid receiving chamber (606) which are not communicated with each other in the heater (6), wherein at least one liquid receiving chamber is received in another liquid receiving chamber, the heating element (602) heats the liquid in one of the liquid receiving chambers, and the heated liquid further heats the liquid in other liquid receiving chamber(s). By means of the liquid heater, the liquid in at least one liquid receiving chamber is not in direct contact with the heating element, but is indirectly heated by means of the heat transfer from an already heated liquid, so as to prevent the problem of a corrosive liquid corroding the heating element, thus improving the service life of the heating element. Further, the present invention avoids using two heaters to individually carry out heating, which would have resulted in a large installation volume and high costs, thus reducing the volume of liquid heater and the costs.
