Embodiment Construction
[0036] First, the hot runner welding of the two plates is completed simultaneously to increase the strength and thermal conductivity of the titanium-coated nano-diamond and the solid solution of the 6063 plate.
[0037] Hot forging 6063 plate mold to form microchannel array spherical plate surface.
[0038] The surface of the plate was pickled, and the surface was vacuum-sprayed with 30 μm thick titanium-plated nano-diamond.
[0039] Merge and align the two boards, leaving a full channel.
[0040] Put them in the vacuum furnace one by one, and at the same time give it an appropriate temperature and diffusion pressure, and quench.
[0041] Slowly infiltrate nano-diamonds into the aluminum alloy to enhance its strength and thermal conductivity.

Abstract
The invention relates to an array spherical hot runner plate type heat exchanger, in particular to an array spherical hot runner plate type evaporator based on a heat pump technology and a vacuum low-temperature evaporation technology. 1,The array spherical hot runner plate type heat exchanger is a falling film plate type heat exchanger formed by welding stamping plates with high heat conductivity6063-T6 and vacuum thermal diffusion nano-diamond enhanced heat conductivity and strength; 2, the plate heat exchanger is composed of boards which are gradually widened at the same height; 3, the bottom is conical to contain raw materials; and 4, a full-automatic process of feeding, evaporating, monitoring and qualified product discharging is formed. The array spherical hot runner plate heat exchanger solves the problems of large occupied area, high investment, high energy consumption, complex and tedious process and the like in the traditional multi-effect evaporation and concentration, andis especially suitable for concentrating and extracting heat-sensitive fruit juice sugarcane juice or Chinese herbal medicines which are easy to oxidize. Vacuum low-temperature concentration is completed in one tank body, meanwhile, food safety is guaranteed, secondary pollution or a manual sterilization link is eliminated, and the working requirements of lowering the labor intensity and the likeare met.
Description
technical field [0001] The invention relates to the technical field of shell-and-tube heat exchangers of plate heat exchangers, in particular to the technical field of heat pump hot runner aluminum alloy plate heat exchange. Background technique [0002] Most of the existing shell-and-tube heat exchangers and plate heat exchangers in the market are 304#, 201#, 316# food stainless steel, which are heavy in weight, large in size, low in thermal conductivity, easy to scale (breeding bacteria to deteriorate heat transfer), and thermal conductivity ≥ 16W / m·k, taking MVR evaporative concentration as an example, low temperature difference, large area fouling worsens, and the heat transfer area is 5-6 times that of ordinary heat exchangers. [0003] The traditional aluminum plate heat exchanger has high thermal conductivity, light weight and low cost, but it is not resistant to corrosion, and it is easy to produce aluminum ions and pollute raw materials. The invention is based on ...
