Description
Technical field
The present invention relates to a kind of heat exchanger, the air cooling heat exchanger of specifically a kind of forced jet.
Background technology
Heat exchanger is the equipment that the partial heat of hot fluid is passed to cold fluid, also known as heat exchanger.Heat exchanger is being changed
It is occupied an important position in work, oil, power, food and other many industrial productions, heat exchanger can be used as in Chemical Manufacture
Heater, cooler, condenser, evaporator and reboiler etc., are widely used.Air cooling heat exchanger is one kind of heat exchanger, tradition
Air cooling heat exchanger generally use natural air cooled or air blast cooling, and air blast cooling by motor drive fan reach air stream
Logical effect is suitable for nonventilated environmental condition indoors.And natural wind is limited to environment, is suitble at the more rich family of wind energy
External environment.But in some use occasions, sluggish in air circulation, the equipment that scene does not allow electrification, and there is requirement of explosion proof, by
To the constraint of field condition, and water-cooled heat exchanger is not applicable, this is just that user brings inconvenience.
Invention content
The purpose of the present invention is to provide a kind of air cooling heat exchangers of forced jet, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the present invention provides the following technical solutions：
A kind of air cooling heat exchanger of forced jet, including holder, heat exchanger tube, ventilation duct and flange, the ventilation duct pass through
Fixed link is fixed on holder, and multiple gas ports are evenly distributed on ventilation duct and gas port is along eight sides of ventilation tube wall surrounding
To arrangement, the top of ventilation duct is provided with gas access, and the bottom end of ventilation duct uses closing structure, heat exchanger tube to be wrapped in ventilation duct
External and fixed using flange, the periphery of heat exchanger tube is provided with multiple Round fins, between adjacent circular fin between be divided into
5mm, flange are fixed on by spirotallic gasket, bolt, gasket and nut in fixed link.
As a further solution of the present invention：Holder is fixed on the ground by pedestal and screw.
As a further solution of the present invention：Spirotallic gasket is made of metal material, and gasket uses silica gel or rubber
Material makes.
As a further solution of the present invention：The outer diameter of gas access is 190mm, and the width of pedestal is 250mm.
Compared with prior art, the beneficial effects of the invention are as follows：The device reasonable design, simple in structure, small, weight
Gently, failure rate is low, safety in utilization and good operation stability；The device is suitable for the occasion that water-cooling pattern is not suitable for, the device
Environmental-protecting performance, energy-efficient performance and heat exchange efficiency stablize, will not because of fouling caused by cooling water in water-cooling pattern the effect that exchanges heat
Rate reduces；The ventilation duct of the device can substitute pressure fan, not allow electrification suitable for scene（It is explosion-proof）Occasion is applicable in model
It encloses extensively, using effect is good.

Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
Please refer to Fig.1-3, a kind of air cooling heat exchanger of forced jet, including holder 1, heat exchanger tube 2, ventilation duct 3 and flange
4, the ventilation duct 3 is fixed on by fixed link on holder 1, and multiple gas ports are evenly distributed on ventilation duct 3 and gas port is along logical
Eight directions of 3 tube wall surrounding of air hose arrange, and the top of ventilation duct 3 is provided with gas access 9, and the bottom end of ventilation duct 3, which uses, to be closed
Structure is closed, heat exchanger tube 2 is wrapped in 3 outside of ventilation duct and is fixed using flange 4, and the periphery of heat exchanger tube 2 is provided with multiple circles
Fin 21, between adjacent circular fin 21 between be divided into 5mm, flange 4 is solid by spirotallic gasket 5, bolt 6, gasket 7 and nut 8
It is scheduled in fixed link.Holder 1 is fixed on the ground by pedestal 10 and screw.Spirotallic gasket 5 is made of metal material, gasket
7 are made of silica gel or rubber material.The outer diameter of gas access 9 is 190mm, and the width of pedestal 10 is 250mm.
The present invention operation principle be：The heat transfer coefficient of air side is that fluid is passed with steel pipe in heat exchanger tube 2 under normal circumstances
The 1/100 of hot coefficient, circular fin 21 is being added in the periphery of heat exchanger tube 2 in we, bigger than 2 inner surface of heat exchanger tube to obtain
The heat exchange area of decades of times, overall heat-transfer coefficient are promoted.Among this circular fin heat exchange pipe 2, we are added one
