Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Embodiments of the present invention are written in a progressive manner.
As shown in fig. 1 to 4 (the direction of the arrow in the figures represents the direction of the airflow), the airflow guiding system for a refrigeration compartment provided by the present invention comprises an air inlet 2 disposed on the refrigeration compartment for introducing air into the refrigeration compartment; the air return port 3 is arranged on the refrigerating compartment body and is used for guiding out air in the refrigerating compartment body; the ventilating space 5 is arranged on the bottom plate 4 of the refrigerating compartment body and used for returning air, and the ventilating space 5 extends from one end of the bottom plate 4 to the other end; the bottom plate 4 comprises a first bottom plate and a second bottom plate with a height difference, and a transition section 41 for connecting the first bottom plate and the second bottom plate, wherein the transition section 41 is obliquely arranged relative to the first bottom plate and the second bottom plate; the transition section 41 is further provided with an air adjusting unit 6, and the air adjusting unit 6 is used for adjusting the air flow in the ventilation space 5 and/or the air flow direction.
According to the airflow diversion system for the refrigeration compartment, air is introduced into the refrigeration compartment 1 through the air inlet 2, and then the air in the compartment is led out through the air return opening 3, so that heat exchange between the inside and the outside of the compartment is realized, the temperature in the compartment is regulated, and the working requirement of the refrigeration compartment 1 is met. In order to prevent the goods stacked on the bottom plate 4 of the compartment from generating serious circulation resistance to airflow, the ventilating space 5 for returning air is arranged on the bottom plate 4 of the compartment, and the ventilating space 5 extends from one end of the bottom plate 4 to the other end. Therefore, even under the condition that goods are fully stacked in the compartment, the bottom of the compartment body can return air normally.
Generally, the air flow guided in through the air inlet 2 flows along the inner wall of the box body under the guiding action of the inner wall of the box body, and finally returns to the air return opening 3 to realize the air flow circulation in the whole box body. However, when the bottom plate 4 of the refrigeration compartment 1 is of a special-shaped structure, for example, in order to match with a skeleton structure of a gooseneck type semitrailer, an expansion part needs to be added at the bottom of the refrigeration compartment body, at this time, a first bottom plate and a second bottom plate with a certain height difference exist at the bottom of the refrigeration compartment body, and the increase of the bottom plate 4 along the airflow flowing direction can generate great resistance to the airflow, so that the flow velocity of the airflow can be greatly reduced while the airflow direction is changed, and the problems of blocked airflow circulation, uneven temperature distribution and poor refrigeration effect in the refrigeration compartment 1 are caused. In order to reduce the adverse effect of the transition section 41 (the area with the height difference on the bottom plate 4) on the bottom plate 4 on the air circulation, the air adjusting unit 6 is arranged on the transition section 41, the air flow in the ventilation space 5 is adjusted through the air adjusting unit 6, and/or the air flow direction is reduced, the energy loss of the cold air flow is reduced, the normal flow of the cold air flow on the bottom plate 4 of the compartment body is ensured, the uniformity of the distribution of the cold air in the compartment body is realized, and the refrigeration effect of the refrigeration compartment 1 is improved.
The airflow guide system for the refrigeration compartment has reliable air supply, can effectively solve the problems of airflow circulation blockage and uneven distribution caused by sudden height change of the bottom plate 4 of the refrigeration compartment 1 under the condition of not changing the main body structure of the refrigeration compartment 1, greatly improves the uniformity of the flow field in the compartment body, promotes the circulation of cold air in the compartment, and further ensures the balance of the temperature in the compartment.
As one of the embodiments of the present invention, it is preferable that the air inlet and the air return opening are disposed on the same side of the refrigeration compartment, and the air return opening is located below the air inlet.
It should be noted that the ventilation space 5 of the present invention can be arranged in various ways, for example, a support frame can be placed on the bottom plate 4 of the refrigeration compartment 1, so that the ventilation space 5 is formed between the support frame and the bottom plate 4; a groove can also be arranged on the bottom plate 4 of the refrigeration compartment 1, and when the bottom plate 4 is filled with goods, cold air flow in the compartment can still circulate in a gap between the groove and the goods. Of course, the ventilating space 5 may also be of another form than these two, provided that there is a certain clearance between the goods and the floor 4.
Due to the transition section 41 with abrupt height change (especially, the height of the bottom plate is increased along the airflow flowing direction) on the bottom plate 4 of the compartment body, when the airflow moves to the transition section 41 along the ventilation space 5, the airflow moves upwards and backwards under the blocking effect of the transition section 41, so that the flowing direction of the cold airflow deviates from the flowing direction required by normal work, and the flowing speed and the energy of the cold airflow are greatly lost.
In order to solve the problem, reduce the influence of the transition section 41 on the flow field in the compartment, and ensure that the cool air flows along the normal circulation path, the air adjusting unit 6 in the embodiment of the present invention may include a wind shielding mechanism 61, specifically, the wind shielding mechanism 61 is disposed above the ventilation space 5, and cooperates with the transition section 41 to form the guiding channel 51 of the air flow.
As an embodiment of the present invention, the wind shielding mechanism 61 may include a fixed baffle plate, and the fixed baffle plate is fixed above the ventilation space 5, so that the fixed baffle plate and the transition section 41 cooperate to form the guide passage 51 of the airflow. Thus, even if the airflow is moved in the direction deviating from the horizontal direction by the blocking action of the transition section 41, the airflow returns to the normal path by the guiding action of the fixed baffle plate, and continues to flow in the horizontal direction. Wherein, the arrangement mode of the fixed baffle plate can be various. For example, when the ventilating space 5 is formed by placing a support frame on the floor 4 of the refrigerated compartment 1, the fixing baffle may be fixed to the support frame; when the ventilating space 5 is formed by providing a groove on the bottom plate 4 of the refrigeration compartment 1, the fixing baffle can be fixed above the groove. It should be noted that, there are various fixing manners of the fixing baffle, which may be bonding, bolt and screw connection, welding, etc.
Further, in order to compensate for the flow velocity and energy loss of the transition section 41 to the airflow and solve the problem that the airflow stagnation area is formed by the bent structure in the guide channel 51 and the cold airflow is not smooth in circulation, an air supply unit 62 may be further disposed in the guide channel 51 according to the present disclosure, the air supply unit 62 is used for conveying the airflow from one end to the other end in the guide channel 51, and the flow direction of the airflow in the ventilation space may be further adjusted by the air supply unit.
Specifically, as an embodiment of the present invention, the air supply unit 62 may be a fan, and when the movement of the air flow in the guide channel 51 is blocked, the air flow may be conveyed from one end to the other end in the guide channel 51 by the aid of the fan, so as to compensate for the energy loss of the air flow in the guide channel 51 and promote the normal circulation of the air flow.
Furthermore, the airflow has to pass through the guiding channel 51 at least twice, and the wind direction turning can greatly increase the on-way resistance of the cool airflow, which leads to the unsmooth airflow flowing inside the whole compartment, and reduces the airflow velocity, even the cool airflow can move back in the guiding channel 51 to form a vortex. In order to reduce the wind resistance, the wind shielding mechanism 61 in the embodiment of the present invention may further include a porous baffle 611, and the porous baffle 611 is disposed at an end of the guide passage 51 from which the airflow flows out.
The arrangement of the porous baffle 611 can ensure that when part of the airflow flows along the circulating path, other airflow passing through the pores can continue to move upwards without forming a vortex back, so that the on-way resistance of the airflow in the guide channel 51 can be effectively reduced. In addition, the porous baffle 611 can combing the air flow again, so that the air flow can be diffused in all directions again after passing through the porous baffle 611, and the problem that the air flow is not uniformly diffused at the outflow end of the guide channel 51 due to overlarge air speed of the air flow flowing out of the guide channel 51 is solved. By adopting the mode, the problem of overlarge wind resistance in the guide channel 51 can be effectively solved, the airflow reflux speed is accelerated, the wind pressure difference is reduced, the flow field distribution of the airflow in the compartment is adjusted, and the temperature balance in the compartment is ensured.
It should be noted that the shape of the through holes on the porous baffle 611 can be any, such as a circle, a triangle, a quadrangle, etc.; the number of the same can be set according to the actual use requirement.
Preferably, the wind shielding mechanism 61 may include a movable stopper 612, and the movable stopper 612 is used to adjust the ventilation amount of the porous baffle 611, thereby adjusting the flow rate of the air flow in the ventilation space (particularly, in the guide passage). By adjusting the ventilation amount of the porous baffle 611, the wind resistance inside the guide channel 51 can be adjusted, and the flow field distribution in the refrigeration compartment 1 can be adjusted.
Specifically, the movable blocking member 612 may include a movable blocking piece and a blocking piece driving member; the baffle driving piece is used for driving the movable baffle to move relative to the porous baffle 611, so that the air permeability of the porous baffle 611 is adjusted. The baffle driving member can be a linear motor or other power mechanisms. The flexible length of the movable baffle is controlled through the baffle driving piece, so that the shielding area of the movable baffle on the porous baffle 611 is controlled, and finally the ventilation quantity of the porous baffle 611 is adjusted.
Further, in order to realize the automatic adjustment of the flow field in the car, a first wind pressure sensor 7 and a second wind pressure sensor 8 can be respectively arranged on two sides of the guide channel 51; wherein, the first wind pressure sensor 7 is arranged at the side of the guide channel 51 where the airflow flows in, and the second wind pressure sensor 8 is arranged at the side of the guide channel 51 where the airflow flows out; and the first wind pressure sensor 7, the blowing unit 62, the second wind pressure sensor 8, and the movable blocking member 612 are connected through a wind pressure control circuit.
In the use, gather the wind pressure size of guiding channel 51 air current inflow one side through first wind pressure sensor 7, gather the wind pressure size of guiding channel 51 air current outflow one side through second wind pressure sensor 8, the wind pressure size of gathering two sensors by the wind pressure control circuit is compared, when the wind pressure control circuit detects the wind pressure differential of guiding channel 51 both sides too big, wind pressure in guiding channel 51 is adjusted in real time to the wind pressure of control of wind pressure control circuit control air supply unit 62 and activity blocking piece 612, reduce the wind pressure differential, accelerate the air current backward flow speed in guiding channel 51, adjust the flow field distribution of the interior air current of railway carriage or compartment.
Furthermore, in order to ensure the uniformity of the temperature inside the refrigeration compartment 1 and monitor the temperature control effect of the airflow diversion system in the scheme in time, at least two temperature sensors 9 may be disposed inside the refrigeration compartment 1, and the temperature sensors 9 are disposed on the inner walls of the compartments on both sides of the transition section 41 respectively, with the transition section 41 as a boundary.
The internal temperature of the carriage bodies on the two sides of the transition section 41 is respectively monitored through the temperature sensor 9, the temperature information collected by the temperature sensor 9 is compared and analyzed through the temperature control system, and when the temperature difference between the two sides of the transition section 41 is found to be large, the airflow diversion system is controlled through the temperature control system to adjust the flow field in the refrigerating carriage 1, so that the balance of the internal temperature of the refrigerating carriage 1 is realized.
