Absorption refrigerator condenser based on heat tube bundle with coagulation strengthening function

Abstract

The invention relates to an absorption refrigerator condenser based on a heat tube bundle with a coagulation strengthening function. The absorption refrigerator condenser comprises a vacuum pressure tank, the heat tube bundle, a guide fan housing and a guide exhaust fan, wherein the guide fan housing is fixed above the vacuum pressure tank; the guide exhaust fan is connected with the guide fan housing; the guide fan housing is not communicated with the vacuum pressure tank; heat tubes in the heat tube bundle are vertically arranged; the upper sections of the heat tubes are provided with condensation sections with outer fin structures; the lower sections of the heat tubes are evaporation sections with outer groove structures; the condensation sections are located inside the guide fan housing; the evaporation sections are located in the vacuum pressure tank. The defect caused by a water cooling heat exchanger in the absorption refrigerator condenser is avoided, and the absorption refrigerator condenser based on the heat tube bundle with the coagulation strengthening function has the advantage that the condensing effect is effectively strengthened, and belongs to the technical field of heat tube condensers.

Description

technical field [0001] The invention relates to a heat pipe condenser, in particular to an absorption refrigerator condenser based on heat pipe bundles with enhanced condensation. Background technique [0002] Absorption refrigeration technology has developed rapidly under the circumstance of increasingly prominent energy and environmental problems. Absorption refrigeration machines are widely used because they can use cheap energy and low-grade heat energy, and do not contain CFC-like substances that can damage the ozone layer. . [0003] The condenser is an important part of the absorption refrigeration unit and is the source of refrigerant water in the unit. At present, the condenser in the absorption refrigerator generally adopts a water-cooled condenser, and a cooling water pipeline is arranged in the vacuum pressure chamber, which is a part of the entire cooling water circulation system. Although the heat transfer coefficient of water cooling is larger than that of a...

Problems solved by technology

[0004] The condenser in the unit belongs to the secondary cooling part. The cooling water in the cooling water circulation system must first pass through the absorber of the unit to take away the heat in the absorber. When it flows into the condenser, the water temperature has risen, so the cooling water in the high temperature section It will affect the condensation effect of the condenser; because the cooling water has to pass through a long curved pipeline in the absorber before flowing into the condenser, the flow rate of the cooling water in the condenser pipeline is relatively slow, and the cooling water is easy to deposit and condense. Scale, the fouling layer formed on the surface of the pipeline will greatly reduce the heat transfer coefficient of the pipeline and increase the condensation pressure of the condenser, which will affect the performance of the entire unit; Sub-scale corrosion or even bacterial corrosion is more likely to occur in the water pipeline, which may corrode the pipeline and make the unit unable to work; and the use of water cooling will complicate the pipeline layout of the vacuum pressure chamber
