Embodiment Construction

[0009] For example, the metal heat exchange tube 1 in the attached figure, after being bent and formed, the entire surface is hot-plated with tin, and the heat source 2 (here only takes the electric heating plate as an example) is also pre-hot-plated with tin on the side of the metal heat exchange tube to fix the heat exchange tube And assemble the mold, turn on the electricity to preheat the flat heat source, when its temperature is higher than the melting point of the tin-based alloy, pour in another melted tin-based alloy 3, for the non-metallic heat exchange tube, just change the material of the heat exchange tube , the overall structure and manufacturing process are exactly the same. The most important thing to pay attention to is the selection of tin-based alloys with low melting points, such as 63 tin with a melting point of only 183°C (63% tin content and 37% lead content). is very safe. In the same way, for metal heat exchange tubes, the alloy composition and its mel...

Abstract

The invention discloses a rapid water sample heater. The rapid water sample heater is composed of a heat exchange tube 1 attached to the surfaces of heat sources 2 or clamped between the two heat sources, a heat conducting medium 3 filling all gaps between the heat exchange tube and the heat sources, and a temperature sensor 4, and the rapid water sample heater is characterized in that the heat conducting medium between the heat exchange tube and the heat sources uses tin-based alloy, and known heat conducting oil, or a metal aluminum casting method in which "thermal resistance" may exist is replaced.

Description

technical field [0001] The present invention generally relates to a fast design and manufacture method for a water sample heater, in particular to a water sample preheater for an automatic water quality component analysis instrument. Background technique [0002] Many water quality component analysis instruments, in order to speed up the process of certain chemical reactions, or to maintain the temperature control requirements during the analysis reaction process, must heat the water sample to a certain set temperature, and almost all heat sources in the structure use power. , and the resistance heater with convenient temperature adjustment, and the water sample conducts heat exchange with the heat source as closely as possible through the slender heat exchange tube. The known method is: for metal heat exchange tubes (the most used is stainless steel), after being bent into a predetermined shape, the heat exchange tube and the electric heating tube can be cast together into ...
