The invention discloses a closed-type dual-channel fin radiator. The closed-type dual-channel fin radiator is characterized in that heat transfer unit layers are formed by corrugated fins; in each heat transfer unit layer, a row of medium channels are arranged in bilateral symmetry and divided into medium inlet channels which are communicated with medium inlet pipes and medium outlet channels which are communicated with medium outlet pipes; the medium inlet pipes and the medium outlet pipes in the same heat transfer unit layer are arranged at the same end of the heat transfer unit layer, and at the other end of the heat transfer unit layer, a medium back-turning end which is formed by a group of communicated back-turning channels is formed between the medium inlet channels and the medium outlet channels; multiple heat transfer unit layers can form a heat transfer core, a first medium and a second medium respectively flow in the neighboring heat transfer unit layers so as to form pure countercurrent flow between the first medium and the second medium. The closed-type dual-channel fin radiator is made of metallic titanium and has high heat-dissipating efficiency and strong anticorrosion performance.
Description
technical field [0001] The invention relates to a plate-fin heat dissipation device, more specifically to a heat dissipation device used for rapid cooling of fresh water, sea water, freezing liquid and other media with low viscosity and low flow rate. Background technique [0002] Plate-fin radiators are widely used in industrial and civil fields because of their high heat transfer efficiency, and their main function is to rapidly cool or heat process media. [0003] At present, the common structural type of plate-fin radiators is a cross-flow flow mode with one side open. The medium on one side is air, which comes directly from the atmosphere, and the medium on the other side is cooled or heated liquid. This type of plate-fin radiator Heat sinks are often made of aluminum. In order to meet the needs of certain high temperature and high pressure occasions, stainless steel plate-fin heat sinks are used more and more. But for the occasion of heat transfer between liquids, the...
