Refrigerated condenser with electric cooling

Abstract

Refrigeration cooler cooled by a Peltier element.

Description

State of the art

[0001] Reflux condensers for the laboratory have a cooling coil inside through which water flows (Dimroth condensers) or are jacketed with a glass tube through which cooled, flowing water flows. A reflux condenser uses a continuous flow of tap water. Water cooling is only dispensable for solvents with high boiling points. Water is a precious resource. By using alternative cooling methods, water consumption could be reduced when using reflux condensers on a laboratory scale. Description of the invention

[0002] According to the invention, the outer tube of the reflux condenser (1) is cooled by a Peltier element (2) with cooling fins (3). The heat from the warmer cooling fin is dissipated by a small fan (4). The cooling fin attached to the cooling side is provided with a recess that fits the outer tube. A similarly sized cooling fin, also provided with a recess, is attached to the cooler cooling fin and the distillation tube with a Velcro fastener, a rubber band, one or more screws, or by clamping the upper and lower cooling fins.

[0003] For better heat dissipation, the outer tube of the reflux condenser (1) can be covered with a metal sheet (6), e.g., made of copper, at the level of the Peltier element. A cooling coil is no longer required.

Claims

[1] Reflux condenser cooled by a Peltier element. [2] Attaching the Peltier element with cooling fin to the reflux condenser with a rubber band, a Velcro fastener, a clamped or screwed cooling fin opposite the cooling fins.
