Abstract
The utility model provides an interlayer pipeline device in a low-temperature storage tank. The interlayer pipeline device comprises a thermal bridge, wherein the thermal bridge is positioned in a vacuum interlayer; the thermal bridge stretches out of a heat-insulating layer, is bent downwards and then extends upwards to be connected with an outer top shell cover. By adoption of the structure, the interlayer pipeline device in the low-temperature storage tank can effectively remit the heat transfer phenomenon of the thermal bridge.
Description
Technical field
The utility model relates to the refrigerated storage tank technical field, refers to especially the inner interlayer piping installation of a kind of refrigerated storage tank.
Background technique
The key performance of refrigerated storage tank is its heat-insulating property, make external heat import as few as possible internal tank into, will be from three kinds of forms of conducting heat, i.e. and conduction, convection current and radiation take in respectively.Wherein the heat conduction is exactly by the heat bridge transferring heat between outer cover head and the inner bag, and these heat bridges are exactly supporting element, the medium parameter sensor conduits such as medium turnover pipeline, pressure and liquid level that connect between outer cover head and the inner bag.
Refrigerated storage tank interlayer high vacuum has effectively stoped heat transfer by convection, and the Multilayer radiation-proof screen in the interlayer has also effectively stoped radiative heat transfer.Therefore, the heat transfer by conduction by heat bridge has consisted of the main body of conducting heat in the refrigerated storage tank inside and outside, surpasses 80% of whole heat outputs.Prior art does not have fine addressing this problem.
The model utility content
The utility model proposes the inner interlayer piping installation of a kind of refrigerated storage tank, solved the poor problem of the inner interlayer effect of heat insulation of refrigerated storage tank in the prior art.
The technical solution of the utility model is achieved in that the inner interlayer piping installation of a kind of refrigerated storage tank, comprises heat bridge, and described heat bridge is arranged in vacuum sandwich, and wherein said heat bridge stretches out from heat insulation layer, bends backward upper extension downwards, is connected with outer cover head.
Preferably, the downward snakelike bending of described heat bridge.
Preferably, described heat bridge material is 304 stainless steels.
Preferably, described heat bridge is arranged in the vacuum sandwich in left side.
Adopt the inner interlayer piping installation of refrigerated storage tank of this structure, owing to lengthened the length of heat bridge, effectively reduced the heat of heat bridge conduction.Simultaneously, the heat bridge material is 304 stainless steels, and is with low cost, reduced holistic cost of the present utility model, improved its practicability.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plane structure schematic representation of the inner interlayer piping installation of the utility model refrigerated storage tank.
Among the figure, 1, heat bridge; 2, heat insulation layer; 3, vacuum sandwich; 4, outer cover head.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
For sake of convenience, the direction to that indicated in the drawings of direction described in the literary composition is consistent, but this direction is not construed as limiting structure of the present utility model.
As can be seen from Figure 1, the inner interlayer piping installation of refrigerated storage tank of the present utility model comprises heat bridge 1, and heat bridge 1 is arranged in vacuum sandwich 3, and downward bending is stretched out from heat insulation layer 2 in this heat bridge 1 bottom, extends upward afterwards, and its top is connected with outer cover head 4.
The calculating formula of heat transfer by conduction is:
Q=（λ·A·ΔT）/L
Wherein: λ---the thermal conductivity of heat bridge material;
A---heat bridge sectional area;
Δ T---the heat bridge two ends temperature difference;
L---heat bridge length.
Wherein λ, A, Δ T are determined by material and operating mode, adjust and to change the space of its numerical value little.Because heat output and heat bridge 1 length L are inversely proportional to, therefore, the utility model reaches the purpose that reduces heat output by artificial lengthening heat bridge 1 length L, namely by heat bridge 1 bending has downwards been prolonged its entire length.
When heat bridge 1 is arranged in the downward snakelike bending of part of vacuum sandwich 3, the better effects if that reaches, and implement more convenient.
Heat bridge 1 material selection 304 stainless steels reduce implementation cost of the present utility model.Heat bridge 1 can be located in the vacuum sandwich in left side, also can set as required.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
