2results about How to "Improve flow characteristics" patented technology

This utility model relates to the field of heat exchange equipment technology, and in particular to a heat exchanger anti-impact structure. The support consists of a support sleeve and a support plate: the support sleeve is circular and tubular; one end of the support plate is fixed to the outer wall of the support sleeve, and the other end is fixed to the inner wall of the heat exchanger; one end of the support rod is provided with a guide cone; the support rod is inserted into the support sleeve; the first guide plate is disc-shaped, fitted onto the support rod, and located on the other side of the support sleeve; the top of the first guide plate is a guide surface one, on which there is a guide hole one parallel to the axis and a guide hole two extending outwards to the bottom; the second guide plate is disc-shaped, fitted onto the support rod, the top of which is a guide surface two, on which there is a guide hole four parallel to its own axis and located on the outer side, and a guide hole three extending inwards from the top to the bottom. This utility model can disperse the impact force of the fluid, protect the heat exchanger tube bundle, and simultaneously ensure uniform fluid distribution and good flow characteristics.

A resin composition comprising resin components and inorganic particles, subjected to a shear rate of 10 s at 130°C. ‑1 Viscosity V measured below 10 Divide by the temperature at 130℃ and the shear rate at 1 second. ‑1 The value V is obtained by measuring the viscosity V1 at the time of measurement. 10 / V1 is 0.7 or higher.
