Accompanying drawing explanation
Figure 1 shows that the present invention has the schematic diagram of the portable differential pressure precooling device of low-temperature receiver.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The present invention has the schematic diagram of the portable differential pressure precooling device of low-temperature receiver as shown in Figure 1, comprise scalable storehouse body and canyon, described scalable storehouse body adds thermal insulating door thermally insulated door 1, condensation unit 10, evaporimeter 14, fan 15 are installed in described canyon, described condensation unit 10 outside is separated by inside holding dividing plate 11 and described canyon, and the described canyon relative with described condensation unit 10 is provided with exhaust outlet 9.Described condensation unit 10 is connected with described evaporimeter 14 with cold-producing medium muffler 13 by refrigerant feed liquid pipe 12, body top, described scalable storehouse is provided with air outlet 5, described fan 15 is installed on described air outlet 5 place, and body bottom, described scalable storehouse is provided with the return air inlet 6 be communicated with described canyon.
In the present embodiment, described scalable storehouse body is surrounded by the connection of many group insulation slide plate Slidable telescopics, often organizes described insulation slide plate and determines different storehouse body spaces, often organize on described insulation slide plate and be respectively arranged with limited slip wheel.The quantity of insulation slide plate is determined according to actual needs.To have the scalable storehouse body of three groups of insulation slide plates, comprise first group of insulation slide plate 3-1, second group of insulation slide plate 3-2 and the 3rd group of insulation slide plate 3-3, three groups of insulation slide plate 3-1, 3-2, between 3-2, Slidable telescopic connects, the bottom of first group of insulation slide plate is provided with the first limited slip wheel 2-1, second group of insulation slide plate bottom is provided with the second limited slip wheel 2-2, the 3rd group of insulation slide plate bottom, the 3rd limited slip wheel 2-3 is installed, when space is less, by promotion first group insulation slide plate 3-1, make first group to be incubated slide plate 3-1 and second group to be incubated to produce between slide plate 3-2 and to slide, and inside retraction second group insulation slide plate, and positioned by the first limited slip wheel 2-1 and the second limited slip wheel 2-2.If when needing less space, inside the equal retraction of first group of insulation slide plate 3-1 and second group of insulation slide plate 3-2 the 3rd group of insulation slide plate, and positioned by the second limited slip wheel 2-2 and the 3rd limited slip wheel 2-3, thus meet the needs of different refrigeration space.When needs larger space, then first group of insulation slide plate 3-1, second group of insulation slide plate 3-2 and the 3rd group of insulation slide plate 3-3 can be stretched out, meet and use needs.
