AI Technical Summary
Existing refrigerant flow channels in evaporators for snow melting machines are expensive, have limited dimensions, and have a small contact area with stainless steel, resulting in weak welds that are prone to detachment. This leads to low heat exchange efficiency, poor cooling performance, and makes maintenance difficult or impossible, ultimately rendering the machine unusable.
The aluminum flow channel is welded using a brazing process, and combines arc-shaped, flat, and equally spaced inlet, outlet, and unidirectional flow channels to increase the evaporation area. Protrusions are set in the flow channel to increase the contact area, and slots are used to achieve connection, thereby improving the refrigerant utilization rate.
It reduces production costs, improves thermal conductivity and cooling effect, extends service life, increases the evaporation area and contact time of the refrigerant, and improves cooling effect and economic benefits.
