Description
Technical field
The purpose of the present invention is a kind of seals, are especially used for hot systems, such as the thermal storage of motor vehicles
Or heat exchanger.
Background technique
It should be noted that thermal storage is understood to include any device of the professional component made of phase-change material, such as
It can store or discharge calorie, such as the heat exchanger including phase-change material or hot storage battery.
Hot storage battery uses the fluid (such as heat-transfer fluid) for being suitable for circulating between the entrance and exit of battery to operate.
When it circulates, the thermal energy being initially stored in battery is passed to fluid.Thus the fluid heated then can adding in vehicle
Circulation in heat radiator, this allows the heat transfer of fluid to vehicle interior.
Such battery can be also used for preheated liquid, such as engine oil or automatic transmission fluid, and can be with
It is done so before being cold-started motor vehicles.
Energy for limit heat losses and in order to keep form of heat in the battery, it is known to use around the exhausted of battery
Edge wall.
However, this insulation wall cannot make to be limited in battery via the heat loss by thermal siphon or heat transfer of fluid
Near entrance and/or outlet conduit.
Similarly, heat exchanger uses the fluid for being suitable for circulating between the entrance and exit of exchanger to operate.It is exchanging
The fluid to circulate in device can transfer heat to another outer member, such as air stream by exchange surface.
This heat exchanger is used for example as the evaporator or condenser in the heating power circuit of motor vehicles.
When the circulation of fluid stops, it is preferred that include that fluid in exchanger can continue to pass through exchange surface
Transmit the maximum amount of heat.
Then, it needs to limit via fluid near the entrance and/or outlet conduit of exchanger through thermal siphon or heat
Any heat loss of conduction.
Summary of the invention
The purpose of the present invention is overcome these disadvantages.
Particularly, the purpose of the present invention is to propose to a kind of economical and reliable devices, for attached in fluid inlet and outlet
The heat loss of nearly limitation the hot systems especially thermal storage of motor vehicles or heat exchanger.For this purpose, the purpose of the present invention is
It is a kind of for thermal storage or the thermal insulating device of heat exchanger, the seal include pipeline and sealing element, the sealing
Element can allow fluid to circulate in pipeline in closed position sealing pipeline and in open position.
Seal is once placed near the entrance and/or exit opening of hot storage system, just will be comprising in systems
Fluid be located at exterior fluid isolation.This allows reducing by the heat loss of conduction or thermal siphon via fluid.
The test carried out in hot storage battery shows can be with using this seal at the entrance and exit of battery
Heat loss is set to reduce about 80%, so that the time for storing heat in the battery is able to extension 40%.
According to a feature, sealing element is thermal insulation.
According to another feature, seal includes bar, and sealing element is fixed to bar.
According to another feature, seal includes guiding piece, and bar is slideably pacified between a closed position and a open position
In guiding piece.
Another feature according to the present invention, seal include returning to element, are suitable for pushing to close by sealing element
Position (i.e. return element applies restoring force on sealing element, so that the element is returned to closed position).
Return element allow in the duct without fluid circulation in the case where for seal provide good sealing, especially
It is heat seal.Element is returned to further, since existing, pipeline is sealed in closed position, and unrelated with the orientation of seal.
According to another characteristic of the invention, returning to element is spring, such as helical spring.
According to another characteristic of the invention, helical spring is arranged around bar.
It is space-minimized that the arrangement that spring surrounds bar allows spring to occupy, therefore the permission when fluid circulates in the duct
Load loss minimizes.
According to another characteristic of the invention, sealing element has along the section of the flow direction by the fluid in pipeline
Trapezoidal shape or circular shape.
When bar is in an open position, the trapezoidal or circular shape of sealing element allows to obtain in the duct satisfactorily
Fluid flowing.Fluid flowing between open position, pipeline tapping and sealing element is suitable for load damage when fluid being made to circulate
It loses and minimizes.
According to another characteristic of the invention, sealing element includes the shell around chamber.
Shell is preferably made of low Heat Conduction Material, such as plastic material, near the sealing element of seal
Any thermal loss.
According to another characteristic of the invention, chamber is empty or gassy.
The presence of gas also allows to be limited near sealing element by the thermal loss of conduction in chamber, so as in close stance
Set the fluid found on the every side for be isolated in sealing element.
According to another characteristic of the invention, near the fluid inlet opening of sealing element setting in the duct.
According to this embodiment, in open position towards moving inside pipeline, this allows to limit seal and accounts for sealing element
According to space.
According to another characteristic of the invention, near the fluid outlet opening of sealing element setting in the duct.
According to another characteristic of the invention, sealing element and opening have the shape being mutually adapted, so that sealing element exists
Closed position is contacted with open surfaces.
Surface contact between pipeline tapping and sealing element is preferably only the contact of localized contact, this is potentially contributed to
Promote the heat leak near opening.
According to another characteristic of the invention, it returns to element to be arranged between guiding piece and sealing element, at sealing element
When open position, returns to element and compressed.
According to another characteristic of the invention, element is returned to be arranged between the fixing element and guiding piece fixed to bar, when
When sealing element is in an open position, returns to element and compressed.
The invention further relates to a kind of component including hot systems He at least one seal according to the present invention, wherein absolutely
The fluid inlet and/or near exit of hot systems is arranged in edge device.
According to a feature, the hot systems are hot storage battery or heat exchanger.
