Embodiment one
As shown in Figure 1, a kind of heat exchanger with antifreeze function, including heat exchanger portion fill 1, which is characterized in that
Heat exchanger portion fills 1 lower section and installs pneumatic expansion tank 4, and expansion tank 4 and heat exchanger portion are filled 1 with connecting tube 2
Water inlet pipe 1-1, outlet pipe 1-2 connect.
Wherein, water inlet pipe 1-1 is identical with the caliber of outlet pipe 1-2, and the caliber of connecting tube 2 is less than water inlet pipe 1-1 and water outlet
The caliber of pipe 1-2.It is preferred that the caliber of connecting tube 2 is between the 1/3-2/3 of water inlet pipe 1-1 caliber.Threeway is equipped in connecting tube 2
Valve 3, expansion tank 4 are connected to by triple valve 3 with connecting tube 2.
In real work, heat exchanger bursting by freezing main cause is that cool ambient air enters, the thermal-arrest with heat exchanger portion dress
The temperature that water in heat-transfer pipe is reduced after piece contact, during temperature is build-up ice down to water, the appearance on heat exchanger portion tubulature road
Product is constant, and volume increases after water freezing, causes manifold pressure to increase, heat exchanger pipeline tube wall can be pressed when pressure is excessive
It is broken.
Heat exchanger provided in this embodiment has certain hydraulic pressure P2 in pipeline when gas heater works normally, swollen
Air is full of in swollen water tank, pressure P1, under pressure, the water in pipeline enter expansion tank, will be in expansion tank
Air is compressed to P1=P2 and reaches balance.
Since expansion tank is located at the side of loading of heat exchanger portion, cold air through smoke pipe from the side's of the loading onto entrance of heat exchanger portion,
During water freezing in pipeline, the constancy of volume of pipeline, volume increases after water becomes ice, and pressure in pipeline is caused to increase；When
When pressure in pipeline increases, the water energy in pipeline can smoothly enter into expansion tank in the presence of hydraulic pressure, make in expansion tank
Air is compressed, and is increased pipeline to the capacity of water, is reduced the pressure in heat exchanger pipeline, prevent heat exchanger pipeline because of pressure
Cross Major disruptionL.
When there is the impact of excessive hydraulic pressure, the high pressure water in pipeline enters expansion tank, presses the air in expansion tank
Contracting, increases the capacity of pipeline, plays the role of compensator or trimmer pressure.
Embodiment two
A kind of gas heater, which is characterized in that it is with the heat exchanger described in embodiment one with antifreeze function.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the utility model
It is not limited to above-mentioned specific embodiment, it is equal using the improvement of techniques well known and substitution on the basis of the utility model
The protection scope of the utility model is fallen in, the protection scope of the utility model should be limited by each claim and its equivalent
It.The part not illustrated in specific embodiment is the prior art or common knowledge.
