Description
Technical field
The invention belongs to pipe type heat exchanger technical fields, and in particular to a kind of change caliber pipe plate type heat interchanger core body.
Background technique
Industry pipe type heat exchanger generallys use single caliber heat-dissipating pipe and is made at present（Referring to attached drawing 1-3）, common
Heat-dissipating pipe specification have Φ 16, Φ 12, Φ 9.52, Φ 8, Φ 7, Φ 6 and Φ 5 etc..Heat-dissipating pipe passes through tube expansion through in fin hole
So that heat-dissipating pipe and fin hole is formed interference fit, expand cup type mouth in heat-dissipating pipe nozzle, then elbow is installed carry out soldering connection
Form coolant channel.When system works, in the flowing of heat dissipation tube cavity and pipe outer medium heat exchange occurs for refrigerant, and generates
Phase transformation, when gas-liquid phase transition, volume will change, but heat-dissipating pipe caliber is but corresponding to be changed, and causes heat exchange efficiency insufficient.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of to use different tube diameters heat-dissipating pipe on same heat exchanger
Become caliber pipe plate type heat interchanger core body.
The present invention adopts the following technical scheme that solve above-mentioned technical problem, a kind of change caliber pipe plate type heat interchanger core body,
It is characterized in that：It is inserted into different tube diameters respectively in the fin hole that different row's punching of fin have diameter different, the fin hole
Heat exchanger tube forms heat-dissipating pipe and fin hole by tube expansion and is interference fitted, expands cup type mouth in heat-dissipating pipe nozzle and pass through variable diameter
Elbow and common elbow carry out thick rear thin or front fine and rear thick coolant channel before soldering connection is formed, and exist for realizing refrigerant
In Large Diameter Pipeline heat dissipation tube cavity flowing when gaseous state, refrigerant is in liquid in small diameter tube heat dissipation tube cavity flowing.
Preferably, the Large Diameter Pipeline heat-dissipating pipe is 9.52 caliber heat-dissipating pipe of Φ, and small diameter tube heat-dissipating pipe is the heat dissipation of 7 caliber of Φ
Pipe, small diameter tube heat-dissipating pipe are arranged multiple rows of on fin, and Large Diameter Pipeline heat-dissipating pipe is arranged multiple rows of on fin.
The present invention has preceding thick rear thin or front fine and rear thick coolant channel, and then can adapt to the body after refrigerant phase transformation
Product variation, effectively improves radiating efficiency and reduces heat-dissipating pipe weight.

Specific embodiment
In conjunction with attached drawing, the technical schemes of the invention are described in detail, a kind of change caliber pipe plate type heat interchanger core body, in fin 3
Difference arranges the fin hole that punching has diameter different, is inserted into the heat exchanger tube of different tube diameters in the fin hole respectively, makes to dissipate by tube expansion
Heat pipe and fin hole, which are formed, to be interference fitted, and is expanded cup type mouth in heat-dissipating pipe nozzle and is carried out by reducing bend 4 and common elbow 5
Thin or front fine and rear thick coolant channel, radiates in gaseous state in Large Diameter Pipeline after soldering connection is thick before being formed for realizing refrigerant
The flowing of 2 inner cavity of pipe, refrigerant are flowed in liquid in 1 inner cavity of small diameter tube heat-dissipating pipe, adapt to the liquid phase volume change of refrigerant,
It improves heat exchange efficiency and reduces product weight.
By taking 9.52 caliber heat-dissipating pipe of Φ and 7 caliber heat-dissipating pipe of Φ mixing row as an example, than single Φ 9.52 under same volume
The heat exchanger heat exchange efficiency of caliber heat-dissipating pipe improves 15% or more, and heat exchanger tube weight reduces by 12.9%；Processing flow and single caliber
Heat exchanger is identical, does not need employee and grasps additional technical ability.
Basic principle of the invention, main feature and advantage has been shown and described above, do not depart from spirit of that invention and
Under the premise of range, there are also various changes and modifications, these changes and improvements to both fall within claimed invention by the present invention
Range.
