[0002] The air conditioner evaporator is a type of evaporator. The function of the air conditioner evaporator is to use the liquid low-temperature refrigerant to evaporate easily under low pressure, turn into steam and absorb the heat of the cooled medium to achieve the purpose of refrigeration.
[0003] Most air conditioner evaporators are composed of basic fins, guide tubes and frames. Some evaporators with different effects are mostly achieved by changing the shape, size and arrangement of the fins, or changing the layout of the guide tubes, or adding other components to give the evaporator more effects.
[0004] In the prior art, the means to increase the heat absorption effect of the evaporator are generally to increase the number of fins, optimize the fin shape, increase the fin surface area, etc. However, these methods usually lead to an increase in the cost of the evaporator, and the improved heat absorption effect is limited. Therefore, how to effectively improve the heat absorption effect of the air conditioner evaporator while reducing the manufacturing cost is a problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide an air-conditioning evaporator with good heat absorption effect. Based on the basic structure, the evaporator significantly improves its heat absorption effect through ingenious design without significantly increasing the manufacturing cost and complexity.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air-conditioning evaporator with good heat absorption effect, comprising an outer frame, a condenser is arranged inside the outer frame, a fin array is installed on the condenser, an inlet air net and an outlet air net are respectively arranged at the two ports of the outer frame corresponding to the two sides, a dustproof net is arranged on one side surface of the inlet air net, there are multiple dustproof nets and they are arranged in a square array, and a trumpet pipe is provided on the inlet air net corresponding to each dustproof net.
[0007] As a preferred embodiment, the trumpet tube is cylindrical, and the inner wall is a trumpet-shaped opening, and the small opening of the trumpet tube on the inlet air net is arranged toward the outside of the outer frame.
[0008] The beneficial effect of adopting the above further solution is that the airflow passing through the inlet air net can be ejected out.
[0009] As a preferred implementation, the trumpet tube on the inlet air net is arranged to penetrate the inlet air net.

[0016] The beneficial effect of adopting the above further solution is to hinder and compress the outflow of the airflow inside the outer frame.
[0017] Compared with the prior art, the advantages and positive effects of the utility model are:
[0018] 1.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] Example 1
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: an air-conditioning evaporator with good heat absorption effect, including a condenser tube 2 and a fin array 3 which are the main components of the evaporator itself, the connection between the two is the connection between the conventional condenser tube 2 and the fin, the fin array 3 is mainly arranged in the outer frame 1, and the condenser tube 2 is arranged through the outer frame 1 at each bend, so as to complete the fixation between the outer frame 1, the condenser tube 2 and the fin array 3 in turn, and the two ports of the outer frame 1 are respectively connected with an inlet air net 4 and an outlet air net 5, and the inlet air net 4 and the outlet air net 5 are both provided with a trumpet tube 6 and a dustproof net 7;
[0029] In this embodiment, the inlet air net 4 and the outlet air net 5 play the role of connecting the trumpet tube 6 and the dustproof net 7 on the basis of the conventional filter net, so their material is different from that of the general filter net, and is a metal mesh material with higher rigidity. When the trumpet tube 6 and the dustproof net 7 are respectively arranged on both sides of the fin array 3, due to their structural characteristics, the airflow entering the outer frame 1 can be adjusted, and it is also adjusted before discharge, which is more convenient to improve the heat absorption effect.
[0030] Example 2
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the two ports of the outer frame 1 are respectively an inlet air net 4 and an outlet air net 5, which are used to act as a filter and are also mainly used to connect the horn tube 6 and the dustproof net 7. The mesh diameter of the dustproof net 7 is larger than the mesh diameter of the outer frame 1. The inlet air net 4 is arranged at the air inlet port of the outer frame 1, and the outlet air net 5 is arranged at the air outlet port of the outer frame 1.
[0032] Among them, the inner wall of the trumpet tube 6 is trumpet-shaped. When its small opening is on the air inlet side, the dust-proof net 7 corresponding to the small opening intercepts the airflow and slows down its impact. Since the cross-sectional area of the air inlet side of the trumpet tube 6 is smaller than the cross-sectional area of the air outlet side, the trumpet tube 6 can play the role of a Venturi tube.
[0033] Therefore, the airflow can be ejected when passing through the horn tube 6. At this time, the volume of the airflow expands under the influence of the change in wind pressure, so that the air pressure inside the outer frame 1 increases to a certain extent, thereby increasing the circulation speed of the airflow inside the outer frame 1.
[0034] In addition, since the expansion degree of the airflow is small during this process, the moisture it carries will not evaporate further and will not compete with the refrigerant for heat.
[0035] In this embodiment, when the airflow enters the outer frame 1, it will first be blocked by the dustproof net 7 and the mesh holes on the outer frame 1. Since the mesh holes of the dustproof net 7 are larger, the airflow can more easily pass through the dustproof net 7 into the trumpet tube 6. Due to the trumpet mouth setting of the trumpet tube 6, the airflow will be sprayed when passing through the trumpet tube 6, which not only causes the airflow to expand, but also accelerates the contact between the airflow and the fin array 3.
[0036] Example 3
[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inlet air net 4 and the outlet air net 5 and their related connection structures are arranged in a mirror image, so the trumpet tube 6 on the outlet air net 5 is arranged with its large mouth facing the inlet air net 4. Since the airflow is accelerated by the injection of the trumpet tube 6 on the inlet air net 4, when it reaches the trumpet tube 6 on the outlet air net 5, the airflow will be compressed due to the reduction of the flow cross-sectional area, and while slowing down the flow of the airflow, the airflow is compressed to release more heat for the refrigerant to absorb;
[0038] Among them, it can be seen from the setting positions of the inlet air net 4 and the outlet air net 5 that the airflow is compressed inside the outer frame 1, so when the airflow is compressed and releases heat, the released heat will be first absorbed by the fin array 3, and then transferred to the condenser 2, and finally transferred to the refrigerant for absorption.
[0039] In addition, since the cross-sectional area of the outlet of the trumpet tube 6 on the outlet air net 5 becomes smaller, the discharge of the airflow will be hindered, thereby prolonging the residence time of the airflow in the outer frame 1, and making the fin array 3 absorb the heat of the airflow more thoroughly.
[0040] Working principle:
[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model is provided with an inlet air net 4 at the air inlet port, and an outlet air net 5 at the air outlet port. The inlet air net 4 and the mirror-image-set trumpet tube 6 connected to the outlet air net 5 are combined with the internal environment of the outer frame 1 to form an airflow expansion structure. When the airflow enters the outer frame 1 from the inlet air net 4, it expands after entering the outer frame 1 under the action of the set trumpet tube 6, and when discharged, it is recompressed through the trumpet tube 6 on the outlet air net 5. Therefore, the airflow is in an expanded state when entering the cooling environment in the outer frame 1. At this time, the heat in the airflow will be The airflow is absorbed by the fin array 3, and because the airflow is in a spraying state when passing through the trumpet tube 6 on the inlet air net 4, the contact speed between the airflow and the fin array 3 is faster. At the same time, because the airflow is blocked by the trumpet tube 6 on the outlet air net 5 when it is discharged, the airflow will be retained in the outer frame 1 under the action of resistance, prolonging the contact time between the airflow and the fin array 3, and the airflow will be compressed when passing through the trumpet tube 6 on the outlet air net 5, and the heat released when it is compressed will also be conducted to the fin array 3, and finally conducted to the coolant by the condenser tube 2 connected to the fin array 3;
[0042] In this process, the discharge of the airflow is slowed down to extend the retention time of the airflow in the outer frame 1, and the airflow is compressed by the bell tube 6 to release heat. Under the combined effect of the two, the utility model significantly improves the heat absorption effect of the evaporator.
[0043] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
