Description
Affiliated technical field
The utility model relates to a kind of double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater, is mainly used on the all-glass vacuum thermal-collecting tube solar water heater.
Background technology
At present, the solar-energy water heater vacuum thermal-collecting tube exists easily influenced the problem that interferes with each other by bursting by freezing and hot and cold water each other when the convective exchange winter.Influence heat convection, reduced the heat exchange efficiency of vacuum heat collection pipe.Therefore, the hot water of solution vacuum heat collection pipe freezed in winter bursting by freezing and rising and the cold water of decline is the problem of mutual interference mutually, and the heat exchange efficiency that improves vacuum heat collection pipe is seemed particularly important.Because vacuum heat collection pipe water flowing area is bigger, and lifting speed waterborne is slower, incrustation scale is not easy to rise to water tank with current, and deposits to easily bottom the vacuum heat collection pipe, long-term like this accumulating, will influence the heat exchange efficiency of vacuum heat collection pipe simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater, makes it that antifreeze function be arranged and has the hot water that solve to rise concurrently and the cold water of the decline problem of mutual interference mutually.
The technical scheme that its technical problem that solves the utility model adopts is: double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater, be in the solar vacuum heat-collecting pipe tube chamber, be mounted with the solar vacuum heat-collecting pipe tube chamber is spaced apart two hot and cold water convection current tube chambers that two ends are communicated with, compound being connected with of escapement can be regulated water, the ice conversion causes Volume Changes, bullet compression deformation body device with certain volume, its device has nontoxic, stable performance in water, heat-resisting, characteristic such as anti-aging, pipe compound with playing the compression deformation body device or dividing plate have and play the identical physicochemical property of compression deformation body device, and pipe or dividing plate are equipped with fixed connecting piece.
The pipe of double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater or dividing plate or be glass or for metal or for plastic cement or be material manufacturing such as pottery.
The bullet compression deformation body device of double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater is fixed on pipe or the dividing plate, play the compression deformation body or be the closed pore foamed plastics, or be the sealed elastic air bag, or air bag with opening elastic outer wall for being connected with the water float by air inlet-outlet pipe; Elastic bag or be plastic cement or be material manufacturing such as metal.
Between the pipe that double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater is interior and bullet compression deformation body device is compound or dividing plate and the solar vacuum heat-collecting pipe lumen wall flexible fastening support is installed.
Between the pipe of double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater or dividing plate and the bullet compression deformation body elastic fixing device is installed, plays between compression deformation body and the solar vacuum heat-collecting pipe lumen wall or elastic fixing device is installed.
The operation logic of double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater is: cold water density is big, and is dirty along the bottom of pipe, and hot water density is little, after water is heated, along the upper wall rising of pipe.Cold water enters the downside tube chamber by the bottom of the solar vacuum heat-collecting pipe mouth of pipe, is discharged by the bottom mouth of pipe, rises along the heating of upside tube chamber then, from the top of the vacuum heat-collecting mouth of pipe hot water is discharged, and forms hot and cold water glitch-free optimum convection circulation mutually.Simultaneously, owing to play the big circulation area that the compression deformation body has been occupied tube chamber, the hot and cold water circulation area is reduced, flow velocity increases, and the scale particles in the vacuum heat collection pipe is brought in the water tank, so just can prevent vacuum heat collection pipe inner product water dirt.When temperature reduces, vacuum heat collection pipe is caught a cold when freezing, and has the contract interior gas of this device of characteristic of bullet and meets cold systolic pressure and diminish; under the pressure of freezing and expansion; further shrink, absorbed the stress that water expands and produced near zero degree, protected vacuum heat collection pipe not by bursting by freezing.When the interior water heating temperature that freezes of the empty set heat pipe of taking seriously raise, the ice of vacuum heat collection pipe inside was melted, and water is heated, and this device is replied original shape.
The beneficial effects of the utility model are: double-flow passage and frost cracking preventing vacuum heat-collecting tube of solar water heater, owing to play the compression deformation body bigger volume is arranged, and the vacuum heat collection pipe water capacity is significantly reduced, the back temperature rise of being heated is accelerated, and has improved the collecting efficiency of vacuum heat collection pipe.And fundamentally solved the problem of the icing bursting by freezing of vacuum heat collection pipe, and improved vacuum heat collection pipe thermal cycle priming speed, vacuum heat collection pipe can be used in any environment.And can whole solar water heater be damaged because of single vacuum heat collection pipe bursting by freezing damages.
