Abstract
The invention discloses an air curtain machine which comprises air curtain cases. The air curtain cases are arranged on two sides of a door opening, two first fans are arranged in the air curtain case arranged on one side of the door opening, two second fans are arranged in the air curtain case arranged on the other side of the door opening, the two first fans are arranged in the middle of the corresponding air curtain case and are adjacent to each other, one of the second fans is arranged on the upper portion of the corresponding air curtain case, and the other second fan is arranged on the lower portion of the corresponding air curtain case. The air curtain machine has the advantages that the air curtain machine is mounted at an outlet of the door opening of a cold storage, high-speed airflow can be generated by the air curtain machine, indoor and outdoor spaces are divided into two independent temperature regions, and accordingly leakage of cold (warm) air can be effectively prevented; indoor air and outdoor air are mixed with each other to form the circulating airflow for the air curtain machine, the airflow can be recycled all along, the temperature of the airflow is approximately equal to the internal temperature of the storage, and accordingly extra cold loss can be prevented.
Description
Technical field
The present invention relates to a kind of air curtain, for freezer or quick freezing repository.
Background technology
At present, freezer or quick freezing repository air curtain are the airflow driving through-flow or centrifugal wind wheel to produce by high-speed electric expreess locomotive, form the door curtain that one side is invisible.This burst of airflow is formed by outdoor air, and because outdoor air is normal temperature, the air-flow sprayed by air curtain must produce Re Jiaore with cold air inside, produces loss of refrigeration capacity.Owing to there is the temperature difference inside and outside storehouse, in the moment that freezer opens the door, just have air and form convection current at door opening place, cause storehouse temperature to fluctuate.
Summary of the invention
The object of the invention is to overcome above deficiency, providing one effectively to prevent cold (warming up) gas to leak, can not produce a kind of air curtain of extra loss of refrigeration capacity.
Object of the present invention is achieved through the following technical solutions: a kind of air curtain, comprise the air curtain case being placed in door opening both sides, two the first blower fans are provided with in the air curtain case being placed in door opening side, two the second blower fans are provided with in the air curtain case being placed in door opening opposite side, two the first blower fans are located at the middle part of air curtain case, and be disposed adjacent, one of them the second blower fan is placed in the top of air curtain case, and another the second blower fan is placed in the bottom of air curtain case.
Further improvement of the present invention is: two the second blower fans suck air-flow, air-flow flows in the air curtain case of opposite side under two the second fan action, air-flow is sucked by two the first blower fans, and blows to the air curtain case on opposite by the power of two the first blower fans, the air-flow operation that makes of Zhou Erfu like this.
Further improvement of the present invention is: the front portion of each first blower fan and each second blower fan is equipped with air guiding grid.
Further improvement of the present invention is: each first blower fan and between each second blower fan and air-flow, first gear aerofoil is all housed, and second gear aerofoil is housed between upper downstream.
Further improvement of the present invention is: two the second blower fans suck air-flow, air-flow flows in the air curtain case of opposite side under two the second fan action, air-flow is sucked by two the first blower fans, and blows to the air curtain case on opposite by the power of two the first blower fans, the air-flow operation that makes of Zhou Erfu like this.
The present invention compared with prior art has the following advantages: one group of air curtain is installed at cold-storage door hole outlet place, air curtain produces air-flow at a high speed, indoor and outdoor is divided into two independent temperature regions, can effectively prevent cold (warming up) gas from leaking, the air-flow that this strand circulates for air curtain, is mixed with outdoor air by indoor, recycles always, gas flow temperature and storehouse temperature close, extra loss of refrigeration capacity can not be produced.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that the present invention of many groups combinationally uses;
Number in the figure: 1-air curtain case, 2-first blower fan, 3-second blower fan, 4-air guiding grid, 5-first gear aerofoil, 6-second gear aerofoil.
detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of embodiment of a kind of air curtain of the present invention, comprise the air curtain case 1 being placed in door opening both sides, two the first blower fans 2 are provided with in the air curtain case 1 being placed in door opening side, two the second blower fans 3 are provided with in the air curtain case 1 being placed in door opening opposite side, two the first blower fans 2 are located at the middle part of air curtain case 1, and be disposed adjacent, one of them the second blower fan 3 is placed in the top of air curtain case 1, and another the second blower fan 3 is placed in the bottom of air curtain case 1.Two the second blower fans 3 suck air-flow, air-flow at two the second blower fan 3 flows by action in the air curtain case 1 of opposite side, air-flow is sucked by two the first blower fans 2, and blows to the air curtain case 1 on opposite by the power of two the first blower fans 2, the air-flow operation that makes of Zhou Erfu like this.
The front portion of each first blower fan 2 and each second blower fan 3 is equipped with air guiding grid 4, air guiding grid can be divided into the even and strong air-spray of multiply from blower fan air-flow out, to ensure that this strand of air-flow has the air curtain case arriving opposite compared with wide range, substantially increase the quality of air curtain.Each first blower fan 2 and between each second blower fan 3 and air-flow, first gear aerofoil 5 is all housed, is equipped with second gear aerofoil 6 between upper downstream, baffle plate can make downstream respectively repetitive cycling utilize, do not produce mutual interference between air-flow, stabilize airflow field.
One group of air curtain is installed at cold-storage door hole outlet place, air curtain produces air-flow at a high speed, indoor and outdoor is divided into two independent temperature regions, can effectively prevent cold (warming up) gas from leaking, the air-flow that this strand circulates for air curtain, is mixed with outdoor air by indoor, recycles always, gas flow temperature and storehouse temperature close, extra loss of refrigeration capacity can not be produced.
This air curtain not only singly organizes use, and can organize side by side before cold-storage door more, as Fig. 2, before freezer altogether row have A B C tri-groups of air curtains, use side by side as adopted many groups, completely can substitute cold-storage door to use, this mode is that in modernization freezer, forklift turnover brings great convenience.
