Abstract

In a kind of temperature control tank container, by collet (23) cylindrical ladle bowl (10) is enclosed in an even confined space, wherein utilize every band (20,21) jar surface is become spiral yarn shaped flow channel with separated by spaces between the collet (23), should be every band along the spiral path extension and have the effect of enhancing ladle bowl (10).Strengthen ring otherwise need provide.This flow channel be arranged on an import on the end face and outlet perforate (31,32) is connected so that temperature control medium is around whole jar surface flow.

Description

By DE-A-2, the freight container of a kind of temp controlling tank (calling the temperature control jar in the following text) that 917, No. 364 patents are known, this freight container has a jar that is contained between the two frame end face members, and this jar constitutes at the bottom of by a cylindrical shell and two jars.Surround with a collet all sides with the jar table, two perforates of configuration are used for flowing into and emitting temperature control medium on an one end face, and a perforate is positioned at another top in this perforate.Be provided with every band between jar table and the collet, be used to cause temperature control medium to be forced to flow along the jar table.

Emphasized in the above-mentioned file that collet is set on a kind of planomural face of freight container frame of parallel tubular shape.Between planomural face and cylindrical freight container, have a lot of triangle flow sections, thus most of temperature control medium contact set vanning surface current is moving; More very it, the through hole that is used for media flow is opened in the abutment wall that the longitudinal axis of crosscut jar is provided with, and from the freight container face sizable distance is arranged.

In addition, the space between known freight container face and the collet is by separating by this way every band, and promptly therefore temperature control medium laminar flow can occur substantially along a jar axial flow on very big distance.According to being provided with every being with this scheme, formed stream is equivalent to two to four times less than canister length.In view of these length reasons, not only can be used to make jar cooling but also jar scope of utilizing of the temperature control medium of heating just is restricted.In addition, with regard to heat insulation and cladded material, on the planomural face of freight container frame, dispose collet, need appreciable expensive, and the subsidiary problem that has the package weight that makes whole tank container to increase greatly.At last, this known tank container needs box container framework; Lack this framework, this Known designs does not just match.

Relate to above-mentioned DE-A-2, described another kind of design briefly in 917, No. 364 patents, wherein set spiral is separated out the space to be formed for a kind of flow channel of temperature system control agent every band between shell and inner casing.Yet, the detailed protocol that any requirement obtains the temperature control medium that is forced to flow along inlet orifice to the closed path that exports perforate is not disclosed in this document.

Need the temperature control jar when shipping food especially, this jar is generally made of special steel, is processed to have thin as far as possible tank skin for economically this jar of reason.Therefore, common such tank container need strengthen ring so that obtain the required intensity of tank body in the welding of jar outside face.

An object of the present invention is to propose a kind of temperature control tank container, this freight container does not need complete container framework, but have simple structure and the lightest package weight, also have and make full use of the temperature official post around jar mobile a temperature control medium and the surperficial uniform contact of jar, even and under the thickness situation that reduces the ladle bowl material, also have enough intensity.

For satisfying this purpose, with even number every band around the circumference of jar spaced at equal angles around and form a continuous circulating path substantially from inlet orifice to the outlet perforate.Simultaneously, should every band can be processed to segmentation every band strengthening ladle bowl, and therefore replaced adding in addition and strengthened ring.

In the practicality, temperature control medium only be one deck with several centimeters uniform thickness, along with the cylindrical circumference of jar surface closed contact on the medium that flows through of spiral path, flow through once at least in any direction.The temperature control medium that is matched and rotated continuously by ladle bowl and helical flow path in the even and narrow and small interval of collet, therefore whole flow volume all is used to enlarge jar interchange of heat on surface.

Owing in fact jar be sealed encapsulation, so the used heat insulation and cladded material amount of collet is smaller, and the package weight of tank container also reduces to minimum value.Installing easily every band of spiral extension concerning collet, thisly can obtain more stably support than the ring along common circumferential extension every band, and this is because the former provides load transfer on the axial position of continuous change.

Opposite with the tank container of above-mentioned prior art, the present invention does not need osed top box-type container framework.And structure of the present invention is applicable to tank container, and it is two end members that its middle frame is exactly simplified, and these two end members are connected to a bottom of providing jar for oneself.

From DE-U-1,851, No. 590 patents as can be known, a kind of double walled tank adopts and spirally metal filament is set so that jar housing parts and inner casing are separated.And only partly separated mutually regardless of in fact this known jar inner casing and shell, wherein used metal filament had not both had to plan to be unsuitable for being formed for the continuous and path spaced apart from each other that temperature control medium flows yet.Except that this difference, by be processed into segmentation every band, to strengthen ring similar to common annular arrangement, the compression strength that has increased cylindric jar of shell every band of the present invention.

From US-A-3,335, No. 904 patents another kind of jar, wherein are provided with the relative lower packing material of a kind of structural strength and a spiral strengthens rib as can be known between the endosexine of ladle bowl and uppermost layer.Yet this known freight container is made of glass fiber reinforced plastic, and the space between ladle bowl internal layer and the skin is filled out fully, and this enhancing rib can not be used to provide the passage that temperature control medium is flowed.

Equally, US-A-4,548, No. 335 patent disclosures liquified gas container, its outer jar with interior jar between the space be filled with thermal insulation material.Pipe that is configured in spirally in the thermal insulation material is used for relief liquor gasification and being configured near outer jar to increase the transfer of heat that is changed to gaseous state by liquid state.In addition, the space outside this helical structure can not be used for separating between jar and interior jar is with the flow passage of formation temperature control agent.

Be described in detail most preferred embodiment of the present invention referring now to accompanying drawing, wherein,

Fig. 1 is the diagrammatic side views of a temperature control tank container;
