Description
Technical Field
The utility model relates to a heat exchange equipment technical field especially relates to a shell and tube condenser.
Background
The condenser is a component of a refrigeration system, belonging to a type of heat exchanger, which can convert gas or vapor into liquid and transfer the heat in the tube to the air near the tube in a quick manner. The condenser operation is exothermic and therefore the condenser temperature is high. The condenser is widely applied to the industries of chemical industry, food, medical treatment and the like. The prior art condenser has two hidden dangers: 1. cracks are easy to appear at the welding position of the condenser cylinder body due to thermal expansion and cold contraction; 2. the heat exchange tube is accommodated in the cylinder of the condenser, liquid materials or refrigerant fluid in the inlet tube of the condenser enter the cylinder of the condenser from the inlet tube of the condenser, and the liquid materials or the refrigerant fluid have higher speed, so that the heat exchange tube arranged at the inlet is greatly impacted, the heat exchange tube is easy to damage, and the service life of the condenser is seriously influenced. It is therefore desirable to provide a shell and tube condenser that addresses the above-mentioned problems.
