Description

Technical Field

[0001] The present application relates to the technical field of rail vehicle air-conditioning manufacturing, and in particular to a housing of a roof-mounted air-conditioning unit for a rail vehicle. Background Art

[0002] In rail vehicles, due to the special environment of rail transportation and the huge passenger flow, ventilation and air-conditioning facilities are very important in the design and use of rail cars. Therefore, each car is equipped with an air-conditioning unit, which adjusts the temperature of the air in the car to meet the needs of passengers.

[0003] In the prior art, the air-conditioning unit is generally arranged on the top of the rail car through an outer shell structure. The outer shell structure of the air-conditioning unit is mainly made of stainless steel or steel plates through welding and riveting. The various components of the air-conditioning unit, including the compressor, evaporator, condenser and connecting pipes, electrical parts, evaporating fan and condensing fan are all installed in the outer shell structure, and the positions of the various components are fixed by the outer shell structure of the air-conditioning unit. At the same time, the outer shell structure of the air-conditioning unit is provided with corresponding ventilation holes to ensure that fresh air is provided to the car. However, when the rail vehicle is operated in an area with heavy rain, rainwater will be sucked into the interior through the ventilation holes of the outer shell structure of the air-conditioning unit. Once the rainwater sucked into the outer shell structure of the air-conditioning unit accumulates to a certain amount and cannot be discharged in time, it will not only cause the rainwater to be blown into the car along with the air supply system, but also cause its air intake effect to be poor, and the normal operation of the rail vehicle air-conditioning unit cannot be guaranteed, resulting in high energy consumption of the rail vehicle air-conditioning unit.

[0004] Therefore, there is an urgent need for a rail vehicle roof-mounted air-conditioning unit housing with good drainage effect, good waterproofing and ventilation functions. Utility Model Content

[0005] The purpose of the present application is to provide a roof-mounted air-conditioning unit housing for a rail vehicle to solve the problems of poor waterproofing and ventilation effects in the prior art.

[0006] The embodiments of the present application can be implemented through the following technical solutions:

[0007] A housing of a roof-mounted air-conditioning unit for a rail vehicle comprises a main frame, a first cover plate assembly, a second cover plate assembly, and two side cover plate assemblies. A water retaining strip is provided on the top of the main frame, and the first cover plate assembly and the second cover plate assembly are respectively connected to two sides of the top of the main frame along the length direction of the water retaining strip.

[0008] The two side cover plate assemblies are respectively arranged on both sides of the main frame and are connected to the first cover plate assembly and the second cover plate assembly. A baffle is arranged on the inner side of the side cover plate assembly, and the baffle is connected to the side of the main frame.

[0009] Furthermore, the water retaining strip is provided at the connection gap between two adjacent cover plate assemblies and is fixedly connected to the upper top surface of the main frame;

[0010] The upper surface of the water retaining strip is lower than the top of the first cover plate assembly and the second cover plate assembly.

[0011] Furthermore, the main frame further includes a partition provided inside the main frame along the length direction of the water retaining bar, dividing the accommodating cavity in the main frame into a first accommodating cavity and a second accommodating cavity;

[0012] The first cavity is located below the first cover plate assembly, and the second cavity is located below the second cover plate assembly.

[0013] Furthermore, a drain port is provided in each of the first cavity and the second cavity. The drain port is an opening provided along the length direction of the baffle, and the drain port is provided at the bottom of the baffle.

[0014] Furthermore, the baffle further includes a heat dissipation hole and a water shield. The water shield is arranged on the outside of the heat dissipation hole and extends downward and outward in an arc shape along the top of the heat dissipation hole.

[0015] Furthermore, ventilation holes are provided on the side cover plate assembly, and the heat dissipation holes correspond to the ventilation holes.

[0016] Furthermore, the first cover plate assembly further includes at least two first cover plate covers, and the at least two first cover plate covers are connected to each other.

[0017] Furthermore, the second cover plate assembly further includes at least two second cover plate covers, and the at least two second cover plate covers are connected to each other.

[0018] The embodiments of the present application provide a roof-mounted air conditioning unit housing for a rail vehicle, which has at least the following beneficial effects:

[0019] The present invention provides a water retaining strip outside the shell and a drainage hole inside the cavity, which can effectively block rainwater from entering the cavity through the outside of the shell, and can collect and discharge the accumulated water that enters the cavity through the shell, effectively reducing the possibility of water accumulation in the cavity, and has the advantages of good waterproof effect and good drainage effect;

[0020] On this basis, the present application seals the cover plate assembly in different areas, which not only achieves a waterproof effect but also facilitates the inspection and maintenance of various components in the cavity;

[0021] The present application can effectively reduce the possibility of rainwater on the side cover being sucked into the air-conditioning unit by setting a baffle, and the heat dissipation holes and water shields opened on the baffle can not only effectively dissipate heat, but also effectively prevent rainwater from entering the air-conditioning unit through the heat dissipation holes.

Their names may be different in the detailed description and claims of the present application.

[0032] The vocabulary in this specification is used to illustrate the embodiments of the present application, but is not intended to limit the present application. It should also be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or a communication between the two components. For those skilled in the art, the specific meanings of the above terms in this application can be specifically understood.

[0033] like Figures 1 to 6 As shown, a housing of a roof-mounted air-conditioning unit for a rail vehicle comprises a main frame 1, a first cover plate assembly 2, a second cover plate assembly 3, and two side cover plate assemblies 4. A water retaining strip 11 is provided on the top of the main frame 1. The first cover plate assembly 2 and the second cover plate assembly 3 are respectively connected to both sides of the top of the main frame 1 along the length direction of the water retaining strip 11, so that rainwater on the top of the first cover plate assembly 2 and the second cover plate assembly 3 can flow out through the water retaining strip 11.

[0034] The two side cover plate assemblies 4 are respectively arranged on both sides of the main frame 1, and are both connected to the first cover plate assembly 2 and the second cover plate assembly 3. A baffle 5 is provided on the inner side of the side cover plate assembly 4. The baffle 5 is connected to the side of the main frame 1 and corresponds to the ventilation hole 41 of the side cover plate assembly 4, and is used to prevent rainwater from being directly sucked into the interior of the air-conditioning unit through the ventilation hole 41.

[0035] Specifically, such as Figure 4As shown, when the first cover plate assembly 2, the second cover plate assembly 3 and the two side cover plate assemblies 4 are respectively connected to the main frame 1, a connecting gap will be formed between the two adjacent cover plate assemblies. The water retaining bar 11 is arranged at the connecting gap and is fixedly connected to the upper top surface of the main frame 1. The upper top surface of the water retaining bar 11 is lower than the top of the first cover plate assembly 2 and the second cover plate assembly 3, so that the water retaining bar 11 cooperates with the side surfaces of the first cover plate assembly 2, the second cover plate assembly 3 and the side cover plate assembly to form a channel for discharging rainwater accumulated on the top of the air-conditioning unit casing.

[0036] In some preferred embodiments, when the first cover plate assembly 2 and the second cover plate assembly 3 are connected to the top of the main frame 1, a receiving cavity is formed in the main frame 1. In order to further improve the waterproof effect inside the air-conditioning unit shell and realize independent partitioning, the main frame 1 further includes a partition 12 provided inside the water retaining bar 11 along the length direction thereof, such as Figure 5 As shown, the partition 12 divides the accommodating cavity into two independent cavities for independently dividing functional areas;

[0037] Among them, the cavity located below the first cover plate assembly 2 is the first cavity 13, and the cavity located below the second cover plate assembly 3 is the second cavity 14. The first cavity 13 is used to place the integrated pipeline of the air-conditioning unit, and the second cavity 14 is used to place the fan and condenser. Through the above arrangement, rainwater in the second cavity 14 can be effectively prevented from entering the first cavity 13, thereby improving the waterproof effect.

[0038] In some preferred embodiments, in order to further improve the waterproof effect in the cavity, the first cover plate assembly 2 also includes at least two first cover plate covers 21, and the at least two first cover plate covers 21 are connected to each other and can be sealed with sealing strips, which are used to seal the areas according to the various working components in the first cavity 13, which can not only enhance the waterproof effect, but also facilitate the maintenance of each component.

[0039] Correspondingly, the second cover plate assembly 3 can also adopt the above-mentioned setting, that is, the second cover plate assembly 3 also includes at least two second cover plate covers 31, and the at least two second cover plate covers 31 are connected to each other and can be sealed with sealing strips. Each second cover plate cover 31 can selectively open a ventilation hole according to the functional module in the second cavity 14, which can not only increase the convenience of use, but also facilitate the maintenance of each component.

[0040] In some preferred embodiments, in order to facilitate the drainage of the accumulated water in the first cavity 13 and the second cavity 14 , a drain port 51 is provided in each of the first cavity 13 and the second cavity 14 .

[0041] Specifically, such as Figure 6 As shown, the drain outlet 51 is a long strip opening arranged along the length direction of the baffle 5. The drain outlet 51 is arranged at the bottom of the baffle 5, so that the accumulated water in the first cavity 13 and the second cavity 14 can flow out through the drain outlet 51 along the bottom of the air-conditioning unit shell.

[0042] In some preferred embodiments, the baffle 5 also includes a heat dissipation hole 52 and a water shield 53. The water shield 53 is arranged on the outside of the heat dissipation hole 52 and extends downward and outward in an arc shape along the top of the heat dissipation hole 52 to cover the outside of the heat dissipation hole to prevent water from entering the interior of the air-conditioning unit casing through the heat dissipation hole 52.

[0043] The above is a detailed introduction to the specific implementation methods of the present application. For those skilled in the art, several improvements and modifications can be made to the present application without departing from the principles of the present application. These improvements and modifications also fall within the scope of protection of the claims of the present application.
