Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a base station air conditioner with an integrated fresh air structure. Background Art

[0002] A base station air conditioner is an air conditioning device specially designed and manufactured for communication base stations, with functions such as large air volume, high sensible heat, high-efficiency filtration, and remote control. In a communication base station, stable and effective temperature control management is one of the key factors to ensure the normal operation of communication equipment, and its functions and performance are crucial for the normal operation of the base station.

[0003] The layout methods of the fresh air structure in such air conditioners are mainly split type or separate fresh air fans. Both the split type and the separate fresh air fans mean that the fresh air system and the air conditioning system are completely separated and independently provide fresh air for each space. To connect the associated fresh air system and the air conditioning system, additional connecting pipelines need to be arranged to realize the connection between the fresh air system and the air conditioning system, which requires additional structural layout and connection costs. At the same time, when the split type or separate fresh air fan is installed in cooperation with the air conditioner, both the split type or separate fresh air fan and the air conditioner occupy a large space and are difficult to install. When controlling the air temperature and fresh air intake volume in the control room, the air temperature is controlled by the air conditioner and the fresh air intake volume is controlled by the fresh air fan. The two are independently controlled, and the control between the air temperature and the fresh air intake volume is not compatible. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a base station air conditioner with an integrated fresh air structure to solve the problem of additional structural layout and connection costs required when interconnecting the fresh air system and the air conditioning system.

[0005] To achieve the above purpose, the basic scheme of the utility model is as follows: A base station air conditioner with an integrated fresh air structure includes an air conditioning unit and a fresh air unit. The air conditioning unit includes an air conditioning body, a top plate, and a connecting pipeline communicating with the air conditioning indoor unit and the air conditioning body. The fresh air unit is installed between the air conditioning body and the top plate, and the fresh air unit is communicated with the connecting pipeline.

[0006] The technical principle of the utility model is that when installing the fresh air unit and the air conditioning body, the fresh air unit can be installed by means of the original top plate of the air conditioning body. At the same time, the fresh air unit is installed between the air conditioning body and the top plate. The connection between the fresh air unit and the connecting pipeline is closer and smoother. Without additional connecting pipes, the cooperation connection between the air conditioning unit and the fresh air unit can be realized, the wiring is simpler, and the cost is also reduced.

[0007] After the installation of the above-mentioned air-conditioning unit and fresh-air unit, the fresh-air unit is stacked on the air-conditioning unit. The layout of the air-conditioning unit and the fresh-air unit is more compact, making the overall volume of the air-conditioning unit and the fresh-air unit smaller and more convenient for installation at the designated position.

[0008] Furthermore, the fresh-air unit includes:

[0009] A housing, the upper side of which is detachably and sealingly connected to the top plate. The housing is provided with an air outlet and a plurality of air inlets;

[0010] A bottom plate, which is detachably and sealingly installed between the lower side of the housing and the upper side of the air-conditioning body;

[0011] A fan, which is fixedly installed in the housing, and the air outlet end of the fan is located at the air outlet of the housing;

[0012] A heat exchanger communicated with the air-conditioning body, which is installed between a plurality of air inlets of the housing and the fan.

[0013] Through the above settings, the air outlet and the plurality of air inlets on the housing can cooperate with the fan and the heat exchanger, so that the air flow entering the housing exchanges heat with the heat exchanger, and the fan realizes the control of the air flow speed; while controlling the air flow speed, the residence time of the air flow in the housing can be indirectly controlled, and then the heat exchange time of the air flow with the heat exchanger can be controlled, so as to realize the control of the air flow temperature, and the base station air-conditioning can simultaneously meet the requirements of adjusting the air temperature and the fresh air volume; at the same time, the heat exchanger is communicated with the air-conditioning body, and the air-conditioning body is used to exchange heat with the air flow, so as to make full use of the air-conditioning body and reduce the cost of the structural setting of the fresh-air unit.

[0014] Furthermore, the connecting pipeline is communicated with the bottom plate, and the communication position between the connecting pipeline and the bottom plate is located on the side of the heat exchanger away from the fan.

[0015] Through the above settings, the connecting pipeline and the bottom plate cooperate to allow the air flow entering from the air-conditioning body to enter the housing through the connecting pipeline, and the heat exchanger further heat-exchanges the part of the air flow, so as to improve the heat exchange efficiency of the air flow; at the same time, the separate connection structure between the air-conditioning body and the air-conditioning indoor unit is simplified, the connection between the fresh-air unit and the air-conditioning body is more compact, and the wiring cost is lower.

[0016] Furthermore, the housing includes:

[0017] An upper front plate, which is in the same vertical plane as the outer side of the air-conditioning body;

[0018] An upper rear plate, which is in the same vertical plane as the rear side of the air-conditioning body, and the air outlet is located on the upper rear plate;

[0019] Two side plates are installed between the sides of the upper front plate and the upper rear plate. A number of air inlets are located on the upper front plate and the side plates. The upper sides of the upper front plate, the upper rear plate, and the side plates are detachably and sealingly connected to the top plate, and the upper sides of the upper front plate, the upper rear plate, and the side plates are detachably and sealingly connected to the bottom plate.

[0020] With the above settings, the upper front plate, the upper rear plate, and the side plates can cooperate more closely with the top plate, the bottom plate, and the upper end of the air conditioner body, making the cooperation between the air conditioner unit and the fresh air unit closer and more precise.

[0021] Furthermore, the lower side of the upper front plate is located below the bottom plate and is detachably and fixedly connected to the outer upper edge of the air conditioner body.

[0022] With the above settings, the upper front plate in the fresh air unit can cooperate with the front side of the air conditioner body, reducing some mold opening costs.

[0023] Furthermore, the cross-sectional profile of the heat exchanger is in the shape of the two hypotenuses and the upper base of a trapezoid. Partition plates are fixedly installed between the two ends of the heat exchanger in the shape of the hypotenuse of the trapezoid and the upper rear plate. The air outlet and the fan are both located between the two ends of the heat exchanger in the shape of the hypotenuse of the trapezoid, and the upper base profile of the heat exchanger faces the upper front plate.

[0024] With the above settings, each side of the heat exchanger is more likely to be opposite to the air outlet and the air inlet, which is also convenient for separating the air inlet side and the air outlet side of the housing through the heat exchanger, and is also convenient for the heat exchanger to perform heat exchange on the fresh air entering from each side, improving the heat exchange uniformity and efficiency.

[0025] Furthermore, the center of the upper front plate is in the shape of an avoidance plate protruding away from the center of the housing, and the upper front plate faces the middle part of the heat exchanger.

[0026] With the above settings, the avoidance plate shape of the upper front plate can better accommodate the air flow between the upper front plate and the heat exchanger, and also reserves space for the installation of the fan, so that the air flow entering the housing has sufficient space to stay in the housing.

[0027] Furthermore, an air inlet valve is fixedly installed at the air inlet of the upper front plate.

[0028] With the above settings, the air inlet valve can cooperate with the fan to further control the air intake volume of the fresh air unit, making the adjustment of the air temperature and the fresh air volume more controllable.

[0029] Furthermore, the air inlet valve is located at the center of the upper front plate in the shape of an avoidance plate.

[0030] With the above settings, the air inlet valve can evenly introduce the air flow to the center of the upper front plate in the shape of an avoidance plate, facilitating the uniform transmission of the air flow.

[0031] Furthermore, the air inlets on the side plates are opposite to the two sides of the heat exchanger in the shape of the hypotenuse of the trapezoid.

[0032] Through the above settings, the airflow entering from the side plate can fully act on the side wall of the trapezoidal hypotenuse of the heat exchanger, enabling the airflow entering from the side to also fully conduct heat exchange. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0039] This embodiment is basically as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 . An embodiment of the present invention provides a base station air conditioner with an integral fresh air structure, including an air conditioning unit and a fresh air unit.

The two side plates 203 are installed between the side edges of the upper front plate 201 and the upper rear plate 202, and the two side plates 203 are symmetrically arranged along the vertical center plane of the upper front plate 201 and the upper rear plate 202; first screw holes that coincide with the screw holes at the flange of the top plate 101 are provided at the upper sides of the upper front plate 201, the upper rear plate 202, and the side plates 203; the bottom plate 30 is hermetically installed on the upper side of the air conditioner body 10 by screws, and a number of second screw holes are provided on the side wall of the bottom plate 30. Third screw holes that coincide with the screw holes at the bottom plate 30 are provided at the upper sides of the upper front plate 201, the upper rear plate 202, and the side plates 203.

[0041] Meanwhile, as Figure 1 and 2 shown, the upper front plate 201 and the outer side of the air conditioner body 10 are located in the same vertical plane, the upper rear plate 202 and the rear side of the air conditioner body 10 are located in the same vertical plane. The lower sides of the upper front plate 201, the upper rear plate 202, and the side plates 203 all extend to cover the connection part between the upper end of the air conditioner body 10 and the bottom plate 30. A fourth screw hole for detachably and fixedly connecting to the upper edge of the outer side of the air conditioner body 10 is provided at the lower side of the upper front plate 201.

[0042] As Figures 1-4 shown, an air inlet 204 is provided on each of the upper front plate 201 and the two side plates 203, and an air outlet 205 is provided at the center of the upper rear plate 202. The fan 40 is fixedly installed inside the outer shell 20, and the air outlet end of the fan 40 is located at the air outlet 205 of the outer shell 20; meanwhile, as Figure 4 shown, the heat exchanger 50 is installed between a number of air inlets 204 of the outer shell 20 and the fan 40.

[0043] As Figure 4 shown, a square hole 301 communicating with the connecting pipe 102 is provided at the upper right side of the bottom plate 30, and the connection part between the connecting pipe 102 and the bottom plate 30 is located on the side of the heat exchanger 50 away from the fan 40. The right side of the heat exchanger 50 passes through the square hole 301 to communicate with the main heat exchanger; meanwhile, the cross-sectional contour of the heat exchanger 50 is in the shape of the two hypotenuses and the upper base contour of a trapezoid. Partition plates 501 are fixedly installed between the two ends of the heat exchanger 50 in the shape of the trapezoid hypotenuse and the upper rear plate 202. The air outlet 205 and the fan 40 are both located between the two ends of the heat exchanger 50 in the shape of the trapezoid hypotenuse, and the upper base contour of the heat exchanger 50 faces the upper front plate 201.

[0044] As Figure 1 、 Figure 3 and Figure 4As shown, the center of the upper front plate 201 is in the shape of an avoidance plate protruding away from the center of the outer shell 20, and the upper front plate 201 faces the middle part of the heat exchanger 50; an air inlet valve 60 is fixedly installed at the air inlet 204 of the upper front plate 201, and the air inlet valve 60 is located at the center of the upper front plate 201 in the shape of an avoidance plate; the air inlets 204 on the side plates 203 face the two sides of the trapezoidal hypotenuse of the heat exchanger 50.

[0045] When installing the base station air conditioner with an integrated fresh air structure in this embodiment, the bottom plate 30, the upper front plate 201, the upper rear plate 202 and the side plates 203 are sequentially installed on the bottom plate 30 and the air conditioner body 10 by screws, so that the outer shell 20 is fixed; at the same time, the partition plate 501, the heat exchanger 50 and the fan 40 are installed in the outer shell 20, and the end of the partition plate 501 is connected to the inner wall of the upper rear plate 202 to fix the heat exchanger 50 and the fan 40; then the upper sides of the upper front plate 201, the upper rear plate 202 and the side plates 203 are connected to the top plate 101 by screws, and the assembly of the air conditioner unit and the fresh air unit can be completed, thus forming a base station air conditioner with an integrated fresh air structure.

[0046] In the above process, the original top plate 101 in the air conditioner unit can be utilized to install the fresh air unit more efficiently and stably between the top plate 101 and the air conditioner body 10, making the structure of the entire base station air conditioner more compact, smaller in volume, and more convenient for installation; at the same time, the upper front plate 201 in the fresh air unit can cooperate with the front side of the air conditioner body 10, reducing some mold opening costs; at the same time, when connecting the heat exchanger 50, the heat exchanger 50 cooperates with the main heat exchanger in the air conditioner body 10, and there is no need to additionally set a long connecting pipe between the heat exchanger 50 and the main heat exchanger, the wiring is simpler, and the cost is also reduced.

[0047] At the same time, since the heat exchanger 50 can cooperate with the main heat exchanger in the air conditioner body 10, it can be realized that the air flow entering from the air inlets 204 of the upper front plate 201 and the side plates 203 can fully exchange heat with the heat exchanger 50, and the air flow entering from the air conditioner body 10 is also transferred from the square hole 301 to the heat exchanger 50 of the fresh air unit for further heat exchange treatment, improving the heat exchange efficiency of the air flow; when controlling the air intake volume at the fan 40 and the air inlet valve 60, the air intake rate is also synchronously controlled, and the heat exchange efficiency between the air flow and the heat exchanger 50 can be synchronously controlled, thereby controlling the air flow temperature, and thus controlling the air flow temperature while controlling the fresh air intake volume. Therefore, the base station air conditioner in this embodiment can simultaneously meet the requirements of adjusting the air temperature and the fresh air volume.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
