The specific embodiment
See also shown in Figure 1, the low temperature transfer cart that preferred embodiment of the present invention provided mainly is earlier some cold-storage spares 10 to be positioned in the congealing machine 12, this cold-storage spare 10 is refrigerated to below its eutectic temperature (eutectic temperature), then these cold-storage spares 10 dislocations is gone in this low temperature transfer cart 14.This transfer cart 14 has a compartment 16, wherein has an insulation room 18, and a fridge equipment 20, has an air outlet 22 on the front side wall of this insulation room 18, is delivered in this insulation room 18 in order to the cold airflow that this fridge equipment 20 is provided.
Has eutectic material (eutectic material) (not shown) in these cold-storage spares 10, it is liquid at normal temperatures, after being cooled to below the eutectic temperature, this congealing machine 12 can be solid-state, and can discharge latent heat (latent heat) after being positioned over these cold-storage spares 10 in this insulation room 18, with quicken in this insulation room 18 cooling rate, reach than 20 of this fridge equipments and the lower temperature of minimum temperature can be provided and prolong effects such as temperature retention time.Have some perforation 24 on these cold-storage spares 10, cold air can pass these perforation, can increase the face area of interchange of heat.In addition, can have the cold-storage spare of different eutectic temperatures, be used for controlling the temperature in this insulation room by placement.
After a period of time, because the energy accumulated of these cold-storage spares 10 constantly disengages, the refrigerating effect that makes 10 of these cold-storage spares to provide reduces, and therefore these cold-storage spares 10 need be taken out, send into again in this congealing machine 12 freezing, to recycle.
See also shown in Figure 2ly, these cold-storage spares 10 comprise on top side face 161, leading flank 162 and the left and right side 163 so long as be positioned on this compartment madial wall.Wherein, be respectively arranged with plurality of fixed seat 26 on these sides, see also shown in Figure 3ly, it has the framework of hollow part 28 for each side, and an end has one 30, with this cold-storage spare of access.Be that a rope 32 is arranged on this door 30, and the outer end of this rope 32 is that a hook 34 is arranged, but these hook 34 hooks are lived this cold-storage spare 10,, this cold-storage spare 10 can be hauled out, take out this cold-storage spare 10 to make things convenient for personnel with when opening this door 30.These permanent seats 26 should reduce as far as possible and cover the area that is installed in cold-storage spare wherein 10, to improve the effectiveness of regenerator of cold-storage spare 10 under the prerequisite that does not influence structural strength.
These cold-storage spares 10 be installed in this insulation room 18 positions preferably are positioned near this air outlet 22 or the path that this cold airflow passes through on, so can accelerate cooling rate.Therefore, the permanent seat 26 that is arranged on this insulation room fat top side wall 161 is to be fixed on this top side wall 161 by some legs 36, leave this top side wall 161 1 segment distances so that be installed in cold-storage spare wherein, thus, when cold airflow was flowed through this cold-storage spare 10, this cold-storage spare 10 had more surface and carries out interchange of heat.
Be the uneven problem of temperature traverse in the compartment that solves existing low temperature transfer cart, the cold-storage spare 10 of part is to be placed on cold airflow to be not easy to flow through part, so can make the temperature traverse in this insulation room door more consistent.
Fig. 4 shows the mode that is installed on the cold-storage spare 10 on this insulation room fat front side wall 162, this front side wall 162 is provided with two grooves 38, it just is of a size of and can inserts for a cold-storage spare 10, one 40, has hollow part 42 on it, after this cold-storage spare 10 was inserted, this 40 opening that can close this groove 38 left to avoid this cold-storage spare 10.
Under this equipment, the accessible refrigerating effect of the present invention is as follows: the volume of this insulation room is: 6,433, and 650cm
3, the horsepower output of this refrigerating plant is: 1285 watts, minimum chilling temperature is :-20 ℃, the eutectic temperature of the cool storage material in these cold-storage spares is :-28 ℃.After these cold-storage spares are inserted this insulation room and start this refrigerating plant, we will be incubated in the room the temperature record as shown in Figure 5.Its result shows, device provided by the present invention can be in the time of the 30th minute drops to-11.1 ℃ with temperature by initial 20.4 ℃, in the time of the 149th minute, temperature can be dropped to-20 ℃, and can maintain below-20 ℃ above 10 hours.
Fig. 6 shows a kind of low temperature transfer cart 14, wherein is provided with a dividing plate 44 in this compartment 16, is divided into one first room 181 and one second room 182 in order to should be incubated room 18, and wherein this air outlet 22 is arranged in this first room 181.The eutectic temperature that is positioned over the cold-storage spare 10a in this first room 181 is lower than the cold-storage spare 10b that is positioned in this second room 182, can make the temperature in this first room 181 be lower than this second room 182 thus, this can reach provides two not stratospheric insulation rooms in a compartment.
