Abstract
The invention discloses a kind of thermal insulation dining car, including: described railway carriage is the most internal is provided with heat pipe, described heat pipe includes bringing-up section and isothermal section, described bringing-up section forms closed circuit with described isothermal section, described bringing-up section is internally provided with steam-heating pipe, and the outside of described bringing-up section is coated with electric heating coil.By the way, the simple in construction of the present invention, reliable operation, maintenance amount is little, it is possible to increase heat transfer efficiency and firing rate so that heat is slowly discharged, it is ensured that the isothermal of dining car, is greatly improved the temperature retention time of dining car, and be difficult to overheated.
Description
Technical field
The present invention relates to food heat-insulation technical field, particularly relate to a kind of thermal insulation dining car.
Background technology
Along with hospital is to modernization development, inpatient is more and more higher to the requirement of nutritious food.Nutritious food is to be made by Nutritious Diet Center, and centrally managed distribution, it is desirable to the food temperature delivering to ward is maintained at more than 60 DEG C.At present, the Grade A hospital of a modernization, often eat and about need food delivery 1600 parts, as by the calculating of 50 parts of each dining car, 32 cars, the often subpackage food delivery after food completes of hospital's Nutritious Diet Center need to be filled, this process needs the time of about two hours, must be incubated food in the process.
Existing hospital ward serving trolley has two kinds of mode of heatings: the first is that steam is directly injected into dining car cavity before food delivery, make it be condensed into water to heat food, the defect of this mode be easily make that leaf vegetables is withered and yellow, condensed water is shed on a road during easily collecting does not causes food delivery；The second is electrothermal tube heating, installs electric heating tube in dining car, and this mode quick heating, cooling are also fast, and temperature retention time is short, generally requires post bake, wastes electric energy, and is limited by distribution capacity.
Summary of the invention
Present invention mainly solves technical problem is that: for the deficiencies in the prior art, a kind of thermal insulation dining car is provided, its simple in construction, reliable operation, maintenance amount is little, it is possible to increase heat transfer efficiency and firing rate, heat is slowly discharged, ensure the isothermal of dining car, be greatly improved the temperature retention time of dining car, and be difficult to overheated.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of thermal insulation dining car, including: described railway carriage is the most internal is provided with heat pipe, described heat pipe includes bringing-up section and isothermal section, described bringing-up section forms closed circuit with described isothermal section, described bringing-up section is internally provided with steam-heating pipe, and the outside of described bringing-up section is coated with electric heating coil.
In a preferred embodiment of the present invention, described steam-heating pipe spirality is arranged in the inside of described bringing-up section.
The invention has the beneficial effects as follows: use the heat pipe of abnormal shape design, inside bringing-up section, be provided with spiral steam-heating pipe, simultaneously at the outside cladding electric heating coil of bringing-up section, make dining car can use steam or two kinds of mode of heatings of electrical heating, its simple in construction, reliable operation, maintenance amount is little；Isothermal section uses U-shaped, forms closed circuit with bringing-up section so that heat transfer efficiency is high, isothermal is good, firing rate is fast, and is difficult to overheated, makes heat slowly be discharged, it is possible to be greatly improved the temperature retention time of dining car.
Accompanying drawing explanation
Fig. 1 be a kind of thermal insulation dining car of the present invention railway carriage body in the structural representation of heat pipe；
In accompanying drawing, the labelling of each parts is as follows: 11, bringing-up section, and 12, isothermal section, 2, steam-heating pipe, 3, electric heating coil.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of thermal insulation dining car, including: railway carriage body, this internal heat pipe that is provided with of described railway carriage, described heat pipe includes bringing-up section 11 and isothermal section 12, and described bringing-up section 11 is linear type, described isothermal section 12 is U-shaped, and described isothermal section 12 is perpendicular with described bringing-up section 11, and forming closed circuit, described bringing-up section 11 is internally provided with steam-heating pipe 2, described steam-heating pipe 2 spirality is arranged in the inside of described bringing-up section 11, and the outside of described bringing-up section 11 is coated with electric heating coil 3.
The operation principle of the thermal insulation dining car of the present invention is as follows: because heat pipe is to add liquid (water) after evacuation, therefore the vapourizing temperature of liquid (water) is low, the time is short, and through test, when being heated to 20-40 DEG C, heat pipe gets final product work.During heating, owing to the bringing-up section 11 of heat pipe stores full liquid (water), liquid (water) in available heat pipes heat section 11 is as heat transfer medium, steam-heating pipe 2 is used to heat the liquid (water) in bringing-up section 11, or use electric heating coil 3 to heat the liquid (water) in heat pipes heat section 11, and make the liquid (water) in heat pipes heat section 11 vaporize, steam enters isothermal section 12, at isothermal section 12 latent-heat storage, and make heat pass through heat pipe isothermal section 12 slowly to discharge；After quitting work, along with the reduction of temperature, the steam regelation in isothermal section 12 becomes liquid (water), and drops to bringing-up section.The present invention is greatly improved the temperature retention time of dining car, and heat transfer efficiency is high, isothermal is good, firing rate is fast, and it is overheated to be difficult to.
Present invention is disclosed a kind of thermal insulation dining car, use the heat pipe of abnormal shape design, inside bringing-up section, be provided with spiral steam-heating pipe, simultaneously at the outside cladding electric heating coil of bringing-up section, make dining car can use steam or two kinds of mode of heatings of electrical heating, its simple in construction, reliable operation, maintenance amount is little；Isothermal section uses U-shaped, forms closed circuit with bringing-up section so that heat transfer efficiency is high, isothermal is good, firing rate is fast, and is difficult to overheated, makes heat slowly be discharged, it is possible to be greatly improved the temperature retention time of dining car.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
