Description

A new type of refrigerated container with automatic control air-guiding structure

technical field

The invention relates to the technical field of uniform air supply in refrigerated spaces, in particular to a novel refrigerated container with an automatic control air-guiding structure.

Background technique

When conducting geological research, the most commonly used method is to mine cores and conduct research and analysis on the cores to obtain corresponding geological parameters.

The core is the rock and soil samples taken from the subsurface through drilling during geological exploration, and is used for the identification of material composition and structure, and the testing of physical and mechanical indicators. The core sample is a very important physical geological material. By studying and analyzing it, we can understand the geotechnical structure more intuitively, and it is also one of the important basis for carrying out geological work.

For some important cores, not only do they need to be placed indoors, but also a constant temperature and humidity environment is required to simulate the marine environment, so as to ensure that the components in the core do not change significantly.

In order to ensure that the properties of some precious geological samples remain unchanged for a long time, they need to be stored in a constant temperature library of 1 to 4 °C (average seabed temperature). -20℃ constant temperature warehouse to protect the easily damaged biomolecules in the core. For example, there is a 1800-square-foot cold storage (4°C) in the National Oceanographic Data Collection Center, where geological samples are generally kept for 4 years, except for rare samples (such as Arctic Ocean material). The preserved samples are cut samples, and half of the cut samples are stored in the sample library for future use, and the other half are used for experimental analysis.

At present, the public core warehouses mostly adopt the storage method of large-space three-dimensional cold storage, but some enterprises and institutions still use multiple small cold storages for storage. Due to the small total amount of cores in the enterprise unit, when using large-scale cold storage, the utilization rate of the cold storage is not high and the inventory rate is low. However, the air conditioning system of the cold storage has to provide the cooling capacity of the entire cold storage, and the energy consumption is high. At present, the problem of unreasonable airflow distribution in the cold storage has not been effectively solved due to the lack of test methods, and the uniform airflow distribution can improve the storage effect of goods in the cold storage and reduce the cost of cold storage operation.

Detailed ways

In order to make those skilled in the art better understand the solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

1 to 4, the present invention provides a new type of refrigerated container with an automatic control air-guiding structure, including a hollow and sealed storage body 12;

A cargo rack 120 with a frame structure (a hollow structure) is vertically arranged in the warehouse body 12;

The cargo rack 120 is provided with a plurality of horizontal cargo brackets 121 spaced from top to bottom;

The top of each horizontal cargo bracket 121 is used to place the cargo 10;

The left and right side walls and the top wall of the warehouse body 12 are hollow structures and communicate with each other;

The hollow inner cavity of the left wall of the storage body 12 is the return air passage 4;

The hollow inner cavity of the wall on the right side of the storage body 12 is the air supply channel 7;

The hollow inner cavity of the top wall of the warehouse body 12 is the fan coil unit installation channel 50;

The fan coil unit 5 is installed in the fan coil unit installation channel 50;

The air outlet of the fan coil unit 5 is arranged in the direction of the air supply channel 7;

The return air outlet of the fan coil unit 5 is arranged in the direction of the return air passage 4;

The inner side wall of the air return channel 4 is the air return plate 3;

The inner wall of the air supply channel 7 is the air supply plate 1;

The air return plate 3 is provided with air return air openings 7 at positions corresponding to the gap between any two horizontal cargo brackets 121 distributed up and down;

The air supply plate 1 is respectively provided with air supply air openings 2 at positions corresponding to the gap between any two horizontal cargo brackets 121 distributed up and down;

A guide vane 11 is installed on each air supply outlet 2 .

In the present invention, in terms of specific implementation, as shown in FIG. 3 and FIG. 4 , the return air outlet 7 and the air supply air outlet 2 are elongated shapes.

In Fig. 1 and Fig. 2, the flow direction of the cold air is shown by arrows.

It should be noted that the air supply plate 1 and the air return plate 3 have a number of strip-shaped tuyere of the same size or different sizes; wherein, the number of the strip-shaped tuyere on the air supply plate 1 and the air return plate 3, It should be determined according to the number of layers of stacked goods, but basically the number of stacked layers is equal to the number of air outlets. The position of each air outlet should be set in the middle of the two layers of goods, which is conducive to the effective flow of cold air in the storage body, which can effectively make the internal temperature of the storage body more uniform, and ensure that the internal temperature of the storage body is in a small fluctuation. scope.

In terms of specific implementation, the return air outlet 7 and the air supply air outlet 2 are non-symmetrically arranged structures.

That is to say, the return air outlet 7 should be avoided as far as possible in the position opposite to the air supply air outlet 2, so as to avoid the reduction of the effective utilization rate of the internal energy of the storage body due to the short circuit of the air flow, resulting in an increase in the overall energy consumption of the storage body and causing extreme energy consumption. Big waste, since the main source of electricity is thermal power generation, it can be said that it is equivalent to indirectly causing pollution to the environment.

In the present invention, in terms of specific implementation, the guide vanes 11 may only be arranged on the air supply plate 1 (specifically, the air supply air outlet 2), and if necessary, can also be arranged on the air return plate 3 (specifically, the return air plate 3). tuyere 7).

It should be noted that, in the present invention, since in the airflow organization, the air supply method has a relatively large influence on the airflow organization inside the storage body, and relatively speaking, the return air has less impact on the airflow organization, so the diversion can be used. The plate (ie the guide vane 11 ) controls the air supply mode, while the return air does not need to use the guide plate to control the return air mode.

In terms of specific implementation, the guide vane 11 includes two parts that are connected to each other, and specifically includes a horizontal guide plate 111 and an inclined guide plate 112 ;

The included angle between the horizontal deflector 111 and the inclined deflector 112 is an obtuse angle.

In terms of specific implementation, both the horizontal deflector 111 and the inclined deflector 112 are hinged, so the horizontal deflector 111 can be folded upward under the action of an external force.

It should be noted that, in view of the problem of airflow organization, in order to make the temperature field inside the space uniform, it is generally considered that the best way is to use orifice plate to supply air to form a piston flow, and to discharge the heat in an organized manner, and the distance of discharge is as far as possible. Short, that is, the air age is as small as possible.

It should be noted that, in the present invention, since the air supply space is equivalent to a flat air duct, the orifice plate air supply port (air supply air outlet) of the air supply plate can be changed into a slot type air outlet according to the principle of uniform air supply. , In order to better organize the air flow, there should be no obstacles in the air outlet position of the slit, so the air outlet should avoid the position of the core.

It should be noted that, for the present invention, two flat plates are spliced to form an obtuse-angled guide vane 11 , which is divided into a horizontal guide plate 111 and an inclined guide plate 112 . The main function of the horizontal deflector 111 is to ensure that the speed of the air outlet is perpendicular to the surface of the air outlet; the main function of the inclined deflector 112 is to control the flow of each air outlet, thereby ultimately ensuring the air supply volume of each layer The same as the air supply speed (size and direction), it can ensure that in the tall space, the temperature stratification phenomenon is weak, the temperature distribution inside the storage body is uniform, and the temperature value is constant.

The length and width of the horizontal deflector 111 may be slightly larger than the corresponding length and width of the tuyere to which it is installed.

It should be noted that, in the present invention, if the stacked goods are mainly concentrated in the lower part of the storage body, the inclined deflector 112 can be folded upward to close part of the air supply vents 2, so that the air volume is concentrated in the storage of the cold storage. Below the body 12, the cooling capacity is better sent to the place with the largest cooling load, the cooling capacity is more reasonably and effectively utilized, and the energy consumption of the cold storage is reduced.

Wherein, the horizontal deflector 111 needs to be in a relatively horizontal state; when the inclined deflector 112 is in different tuyere, the inclined deflector 112 may adopt different sizes and different inclination angles.

It should be noted that, in the present invention, the horizontal deflector 111 is used to determine the direction of the air supply speed of the air supply outlet, and under normal circumstances, it should be in a horizontal position; the inclined deflector 112 is used to control each The flow rate of each tuyere, because the air flow in the air duct gradually decreases after the air is divided into each tuyere, in order to ensure the same flow rate of the tuyere, it is necessary to adopt the inclined baffles 112 of different inclination angles and different sizes according to the tuyere of different positions. , used to ensure a constant air volume at the installed tuyere.

Wherein, when determining the air openings on the air supply plate 1 and the air return plate 3, try to avoid cargo or other obstacles in the windward direction of the air openings.

Among them, the air return air outlet on the air return plate 3 may adopt air outlets of the same size, or may adopt air outlets of different sizes, and if adopt air outlets of different sizes. In terms of specific implementation, for the plurality of return air ports 7 on the air return plate 3 , the closer to the fan coil unit 5 , the smaller the size of the return air ports 7 . That is, take a gradual reduction approach.

It should be noted that in the present invention, different air supply speeds can be adopted according to different widths of the cold storage. The temperature distribution of one layer is uniform.

Based on the above technical solutions provided by the present invention, it can be seen that the present invention overcomes the deficiencies of the prior art, provides a technical solution for air supply with good air supply performance and an adjustable deflector for life and production, and solves the problem of the existing air flow. Uneven organization, poor regulation performance and high power consumption.

In order to understand the technical solution of the present invention more clearly, the following describes the air flow process of the present invention.

First, the air is blown out by the fan coil, which reduces the temperature of the air.

Next, the air enters the air supply channel 8 from the right outlet of the fan coil unit, and then flows through each guide vane 11 and enters the interior of the storage body 12. The cold air cools the goods 10 in the storage body 12, and the goods 10. Transfer heat to the air to increase the temperature of the air. The heated air flows to the return air outlet 7 of the return air plate 3 due to the extrusion of the air behind it, and then enters the fan coil unit installation channel 50 through the return air channel 4. , so as to return to the air return port of the fan coil unit 5 .

The air then enters the fan coil unit for cooling for the next cycle.

Compared with the prior art, the cold storage provided by the present invention has the following beneficial effects:

1. Air supply is carried out by means of guide vanes, which can achieve equal air volume and equal velocity (direction and size) air supply, and achieve uniform air supply in the strict sense.

2. By adjusting the inclined guide vanes, the size of the air supply can be changed. If the storage method of the goods in the warehouse changes in the later period, it can be adjusted to meet the requirements applicable to various conditions.

3. Compared with the variable-section air duct, the present invention reduces the inclined plate for ensuring static pressure and reduces the cost of materials.

4. The use of appropriate air supply method not only ensures the uniformity of temperature distribution inside the warehouse, but also improves the utilization factor of energy, reduces energy consumption, and indirectly reduces environmental pollution.

Based on the above technical solutions, it can be seen that the present invention provides a new type of refrigerated container with an automatic control air guide air supply structure, which can be applied to a refrigerator with high precision requirements and a tall, narrow and long space. The plate is used to supply air to solve the problem of uneven temperature distribution in a large refrigeration space (such as a large cold storage), which is beneficial to control the temperature fluctuation range and ensure the quality of the items stored in the storage.

To sum up, compared with the prior art, the present invention provides a new type of refrigerated container with an automatic control air guide and air supply structure, which uses guide vanes to control the air volume and the direction of the wind speed, which can not only accurately control the air volume It flows out from different air outlets, and it can also ensure that the wind speed of each air outlet is in the direction of the horizontal position to ensure uniform air supply, which is conducive to improving the accuracy of temperature control in the refrigerated container, which is conducive to wide application and significantly enhances people's product experience. , which has great practical significance for production.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. It should be regarded as the protection scope of the present invention.
