The cold air circulation in the cabinet accelerates the heat absorption efficiency of the evaporator, the cooling speed is fast, the temperature distribution in the cabinet is uniform, the temperature difference between the upper part and the lower part is within plus or minus 1.5 ℃, and the efficiency is improved by about 30 percent compared with a direct cooling type refrigerated cabinet.
Description
The utility model relates to a kind of refrigerator, particularly a kind of horizontal refrigerator showcase.
Existing horizontal refrigerator cabinet, though be the chamber, separate room or two between the chamber all be direct-cooling type, be that its evaporation tube is to twine along the cabinet wall equidistantly to be close on the cabinet wall with aluminium foil, heat around drawing when its heat exchange only depends on cold-producing medium to flow in evaporation tube, the fin area is less, exchange efficiency is low, and power consumption is big.Be that the diffusion of direct-cooling type cold air is slow again, the upper and lower temperature difference is big in the cabinet, differs sometimes about 10 ℃, influences the cold storage effect of showpiece.CN2276141Y proposes a kind of technical scheme, vent window is all established in front and side at the horizontal refrigerator casing, and configuration compressor, blower fan and condenser, the air that its effect just strengthens compressor and condenser periphery flows, accelerate their heat radiation, and at the heat exchanger effectiveness that improves evaporimeter, it is little to dwindle the interior temperature difference aspect effect of cabinet.
The purpose of this utility model is low at the evaporimeter heat exchanger effectiveness of existing horizontal direct-cooling type refrigerator, and the big defective of upper and lower temperature difference in the cabinet designs the little horizontal refrigerator showcase of upper and lower temperature difference in a kind of evaporimeter heat exchanger effectiveness height, the cabinet.
Design of the present utility model is, air-cooled horizontal refrigerator showcase, and it comprises refrigeration system, cabinet, moving door and power supply, its design feature is to be provided with the pressure circulating cold air air channel of being made up of air channel, left and right sides plate, blower fan and pressing plate in the middle of the cabinet.
Air channel, the described left and right sides symmetrical closing up of plate, blower fan is sandwiched in the middle and upper part of air channel plate, the bottom that closes up is an air inlet duct, and the top of blower fan surrounds flaring air outlet by air channel, left and right sides plate, under the blast effect when fan starting, plate both sides, air channel form separately the circulating cold air of convection current up and down, cold wind is accelerated the heat absorption efficiency of evaporimeter, and cooling rate is fast, and in-cabinet temperature is evenly distributed, upper and lower temperature difference is within ± 1.5 ℃, with the specific efficiency raising about 30% mutually of direct-cooling type refrigerator.This is the outstanding advantage and the marked improvement of present design.

The 26S Proteasome Structure and Function of embodiment is described below in conjunction with accompanying drawing.
The said refrigeration system of the utility model is electronic compression refrigerating system, and it comprises motor, compressor, condenser, filter, flow controller, evaporimeter, cold-producing medium and backflow adapter etc.An evaporimeter and an associated components thereof with refrigeration system are illustrated on the drawing on the enforcement illustration of the present utility model, and miscellaneous part omits as prior art.
The structure of the utility model first embodiment as depicted in figs. 1 and 2, the dividing plate in the middle of Fig. 1 such as the refrigerating box is with the casing portion that is separated in two.It is made up of air channel, left and right sides plate (11,12), blower fan (3) and pressing plate (5) forces the circulating cold air air channel.Blower fan (3) is located at the middle and upper part that air channel, left and right sides plate (11,12) surrounds cavity, the top of blower fan (3) constitutes flaring exhaust passage (4) by liner (7), the lower cavity of blower fan (3) is an air inlet duct, pressing plate (5) covers on the inclined-plane on air channel, left and right sides plate (11,12) top, and the gradient of pressing plate (5) and refrigerator glass move the gradient synthetic sealing state that matches of door (2).The exhaust vent (6) that communicates with exhaust passage (4) is established in the both sides of pressing plate (5), as shown in Figure 2.Fresh air inlet (8) is established in the lower end of air channel, left and right sides plate.The evaporimeter of refrigeration system is to form along the evaporation tube (13) that the refrigerator inwall equidistantly twines, as shown in Figure 5.
Another embodiment of the present utility model as shown in Figure 3 and Figure 4, Fig. 4 is also as the dividing plate in the middle of the refrigerating box, with the casing portion that is separated in two.It is made up of air channel, left and right sides plate (11,12), blower fan (3), evaporimeter (9) and pressing plate (5) forces the circulating cold air air channel.Blower fan (3) is located at the middle and upper part that air channel, left and right sides plate (11,12) surrounds cavity, and the top of blower fan (3) is an air inlet duct by the below that liner (7) constitutes flaring exhaust passage (4), blower fan (3), establishes evaporimeter (9) in the air inlet duct.Pressing plate (5) covers on the inclined-plane on air channel, left and right sides plate (11,12) top, and the gradient of pressing plate (5) and refrigerator glass move the gradient synthetic sealing state that matches of door (2).The exhaust vent (6) that communicates with exhaust passage (4) is established in the both sides of pressing plate (5), as shown in Figure 4.Fresh air inlet (8) is established in the lower end of air channel, left and right sides plate.The distinguishing feature of present embodiment is, to make finned tube evaporator (9) into along the evaporation tube that the refrigerator inwall equidistantly twines, it is contained in by air channel, left and right sides plate (11,12), blower fan (3) and pressing plate (5) forms in the pressure circulating cold air air channel, has improved the heat absorption efficiency of evaporimeter.
The direction of arrow of Fig. 5 and Fig. 6 is represented the direction of circulating cold air in the refrigerator, under the situation of refrigeration system operate as normal, fan starting air channel plate forms draught head up and down, the Quilt with air conditioning forced circulation, the top-down convection circulation of air, the top of blower fan is air outlet all the time, and the lower end of air channel, the left and right sides, the below plate of blower fan is air inlet all the time.The result of cold air convection circulation making in the refrigerator cooling accelerate, and upper and lower temperature difference reduces, the structure of above-mentioned two kinds of embodiment can both make upper and lower temperature difference be controlled at ± 1.5 ℃ within.Different is, and the evaporation tube shown in Figure 5 and the one side of fin are insulation material (1), have only one side to contact, and evaporimeter shown in Figure 6 is a finned tube evaporator, is contained in again in the air channel with circulation cold air, the area of dissipation that ventilated is big, and the efficient of second embodiment is higher.
Blower fan described in the utility model (3) is selected wheeled cross flow fan for use, and it has and takes up room for a short time, and wind speed is stable, makes Temperature Distribution spare equal advantage.
