Abstract
An incubator for accommodating premature and newborn babies in a compartment which can be temperature- controlled by a latent heat store, is improved so that temperature regulation, which can be adapted in an improved way to varying environmental conditions and which is not dependent upon the store temperature, becomes possible in the compartment, and so that when a desired temperature is exceeded, the heat emission can be eliminated. To this purpose, the heat store is housed in a special store space, which is heat-insulated from the compartment and from the environment, and is connected to a controllable heat exchanger which is accommodated in the compartment.
Description
The present invention relates at an indoor placement premature infant of case and a neonatal couveuse by latent heat bin control temperature.
Such couveuse is open in Deutsche Bundespatent A-31 19 213.
The latent heat bin of this known couveuse is made of a kind of material, and this material transmits corresponding conversion (diving) heat to placing premature infant or neonatal case chamber in process of setting after its heating is surpassed its fusing point.The latent heat bin is placed in one or more containers in the convection channel that is contained in the back, thereby the air that makes the couveuse chamber is kept Natural Circulation when having potential to discharge.In order to adjust convection current, adjustable choke valve is housed in the flow path of convection channel.
The thermal storage device of adorning in the convection channel of this known couveuse has unwelcome characteristics, and promptly it constantly discharges corresponding heat towards periphery in process of setting, even also like this under the situation that convection channel is closed by choke valve.Though in the couveuse chamber, no longer carry out convection current,, be incubated the case chamber sidewall that tank wall is adjacent accordingly and still be heated by the heat that in convection channel, constantly discharges.Like this, when premature infant and neonate the couveuse time of staying than long time, higher and when requiring to stop heat supply immediately when ambient temperature especially, the interior space will occur and not wish the heating that occurs.Because thermal storage device requires to have high heat capacity for the heater incubator chamber, so in this case, be cooled to the overlong time that required temperature needs.In addition, have only those solidification temperaturies just to can be used for thermal storage device near consistent material with the couveuse operating temperature.So just limited to the selection of material greatly.The material that solidification temperature is higher although they may be worthy of consideration at aspects such as corrosion resistance, stability, usefulness, operability, reasonable prices, can not adopt.
The objective of the invention is to, the couveuse of the above-mentioned type is improved, make it to adapt to preferably the external condition that is changing, can not be subjected to thermal storage device temperature effect ground to regulate indoor temperature and when surpassing rated temperature, check heat release.
These tasks are accomplished by following approach, thermal storage device be located at couveuse chamber and extraneous heat insulation distinctive keeping warmth space in, and the heat exchanger indoor with being located at couveuse controllably is connected.
When needing, can at any time thermal storage device and heat exchanger be separated on heat links, can continue to store latent heat so on the one hand, can check effective heat release on the other hand again to the thermophore chamber in order to after this need.So just prolonged the resting state time and the working time of couveuse, when not having especially the couveuse of continuous operation under the situation of energy supply a few hours in being used as transportation, these characteristics are especially important.Because may carry out thermal center stream between thermal storage device and heat exchanger, can work on the temperature levels that is lower than the operating temperature of thermal storage device (solidification temperature) in heat exchanger and couveuse chamber.So just can adopt those to make the thermal storage device material and need not to take into account its operating temperature problem of higher at the material that other aspect of performance has advantage.
The position of a particularly advantageous installation thermal storage device is the back at one section wall of couveuse chamber.Can easily touch thermal storage device therefrom, and need not to enter the couveuse inner space.
The rear portion that heat exchanger is arranged on the couveuse chamber is comparatively suitable, and it can install in the perpendicular passage of the convection current of case room air to be heated at this place.
The characteristics of the couveuse of an optimum structure are that thermal storage device contains a guard shield, and there is the fuse of a storage latent heat its inside, and this fuse is surrounded by a kind of liquid or liquid-vapor mixture.The outlet of guard shield is connected with heat exchanger by a controllable valve, thus make heated liquid when valve open and heat exchanger all.Heat exchanger can connect by pipeline only or by pipeline back and forth, this moment liquid exchange or flowing in the opposite direction in or in circulation, carry out.When using lower boiling liquid, for example fluorinated hydrocarbon, it is effective especially to conduct heat.The latent heat of emitting makes liquid boiling, and like this, heated steam enters heat exchanger, and its discharges behind condensation heat condensing on the wall and be back in the guard shield goes.
It is favourable being designed to fuse heatable, and it can reheat after solidifying like this, and couveuse can drop into the next round operation again.So just needn't remove to replace cakey old fuse with a new fuse that has added heat in advance.Especially between its standby period, fuse can constantly heat and remains on more than the fusing point, and the latent heat of emitting can only be used when the work for couveuse.
Accompanying drawing schematically shows one embodiment of the present of invention, is described further below.
Unique this figure is the profile of a couveuse, in its housing (1), between the vertical sidewall of face (4) (3) heat exchanger (5) is housed in its rear wall (2) and with flat crouching.The flat face that crouches of level follows the housing base plate (6) of couveuse to be spaced apart, and below the housing base plate, is with heat-barrier material (21) heat accumulation space (7) that fill, thermal storage device (8).Thermal storage device (8) contains an insulation guard shield (9) that liquid (10) is housed, and the wax core (11) of supplying with latent heat just is inserted in this liquid.Wax core (11) is heated by the heater (12) that is connected on the heater (13).Insulation guard shield (9) has an outlet (14), and it connects with heat exchanger (5) by controllable valve (15).Flat chamber (16) of crouching face (4) place can enter from the outside by the trapdoor (18) that is fixed on the hinge (17).
Heated wax core (11) puts its latent heat to liquid (10), and it is flowed along direction shown in the arrow in heat exchanger (5), and its heat is put to the air in the perpendicular passage (19) of convection current.Jia Re air flows in the case chamber (16) in the free convection mode like this, and leads back the perpendicular passage (19) of convection current by the flat intermediate space that crouches between face (4) and housing bottom (6).Can set up the set-point of air themperature by the incubator (20) that is located in the scope of case chamber (16), and decide the opening degree of valve (15) according to its size.If ambient temperature raises and need not case chamber (16) to be heated again, then can end heat exchanger (5) transfer heat by complete valve-off (15), heat exchanger immediately cools off, yet it can be devoted oneself to work at any time owing to still remain in the interior latent heat of thermal storage device (8).
