The present disclosure provides a method to fabricate three-dimensional transparent glass utilizing polymer plasticity, including the following steps. In step 1, synthesize polymer-glass powder composite containing dynamic chemical bonds, the bond exchange catalyst is added during the synthesis process, and then cure to obtain a two-dimensional sheet shape I, the bond exchange catalyst is used to activate a dynamic chemical bond in step 2. In step 2, shape the two-dimensional sheet shape I obtained in step 1 into a complex three-dimensional shape II under the conditions of the effect of an external force and the activable dynamic chemical bond. In step 3, pyrolyze the composite precursor at high temperature to obtain transparent glass with complex three-dimensional shape II. The present disclosure provides a method in shaping the transparent glass with complex geometries by unique polymer plasticity in lower temperature.

Method to prepare three-dimensional transparent glass via polymer plasticity

A heat exchanger () of a heat exchange device used for air cooling cold water units or commercial roof machines, a method for manufacturing the heat exchanger (), a heat exchange module, a heat exchange device, and a heat source unit. The heat exchanger () comprises: a main body portion (ab); a bent portion (cd) with a trapezoid cross section, the bent portion (cd) and the main body portion (ab) being connected and approximately perpendicular to each other; two collecting pipes (), disposed on two opposite sides of the heat exchanger (); and multiple heat exchange pipes (), each extending from one collecting pipe () of the two collecting pipes () to the other collecting pipe () by passing through the main body portion (ab) and the bent portion (cd), wherein a top edge of the bent portion (cd) and a top edge of the main body portion (ab) of the heat exchanger () are approximately located at the same height level.

Heat exchanger and manufacturing method therefor, heat exchange module, heat exchange device, and heat source unit

Provided are a heat exchanger apparatus and a heat source unit that are for use in a chiller unit. The heat exchanger apparatus comprises at least one heat exchanger module (). The heat exchanger module () comprises two heat exchanger units (and) that are oppositely fitted with each other. At least one between the two heat exchanger units (and) is bent so that an angle between adjacent two edges (c and d) on at least one extremity of the two heat exchanger units (and) is less than an angle between main parts (and) of the two heat ex-changer units (and), thus increasing the area for heat exchange.
