Detailed Description
One embodiment of the present invention provides a power pack, including: a shell body, a plurality of first connecting rods and a plurality of second connecting rods,
a first functional element is accommodated in a first area enclosed by the shell;
a second functional element is accommodated in a second area enclosed by the shell;
a third functional element is accommodated in a third area surrounded by the shell;
the first area and the second area are respectively positioned on two sides of an area enclosed by the shell, and the third area is positioned between the first area and the second area;
the shell comprises air ports at the position corresponding to the first area, the position corresponding to the second area and the position corresponding to the third area respectively.
Therefore, in the invention, the area surrounded by the shell of the power pack is divided, the functional elements of the power pack are placed in different areas, and the air ports are respectively arranged in different areas of the shell, namely in the positions corresponding to the first area, the second area and the third area, namely, the external air enters and exits from the air ports corresponding to the three areas of the power pack. The functional elements are placed in the sub-regions, and the power pack can be cooled more effectively by the aid of the independent air path guiding mode of air inlet and air outlet in the sub-regions. In addition, the independent air path of the power pack is not limited by the whole air path of the air conditioner, and the use flexibility of the power pack is improved.
In one embodiment of the invention, the structure of the power pack can realize air inlet at two sides and air outlet at the middle. At this time, the shell comprises an air inlet at a position corresponding to the first area and an air outlet at a position corresponding to the second area respectively, and comprises an air outlet at a position corresponding to the third area;
in one embodiment of the invention, the structure of the power pack can realize air outlet at two sides and air inlet in the middle. At this time, the housing includes an air outlet at a position corresponding to the first region and an air inlet at a position corresponding to the second region, respectively.
In an embodiment of the invention, when the structure of the power pack is the structure with air inlet at two sides and air outlet at the middle, the functional elements can be placed in different areas according to the temperature characteristics of the functional elements. For example, a high-temperature element with relatively high temperature or an element less sensitive to temperature is placed in the third area, so that air entering the first area and the second area from the air inlets at two sides is converged into the third area, and the high-temperature element in the third area is cooled in a concentrated manner and then discharged, and further the cooling effect on the functional elements of the power pack is improved. And moreover, the high-temperature element with relatively high temperature is placed in the third area, and the functional element with relatively low temperature is placed in the first area and the second area respectively, so that the air from two sides can firstly cool the functional element with relatively low temperature in the first area and the second area, and then the high-temperature element with relatively high temperature in the third area is cooled, so that the high temperature difference between the wind and the functional element to be cooled can be maintained, and the cooling effect on the functional element in the power pack is further improved. In one embodiment of the present invention, the high temperature element may be placed in the third area near the outlet.
In an embodiment of the present invention, when the structure of the power pack is the above structure with air out from two sides and air in the middle, the third functional element may include: a less temperature sensitive and less temperature high element relative to the first functional element and the second functional element. The structure can maintain higher temperature difference between wind and functional elements needing cooling, and improves the cooling effect on the functional elements of the power pack.
In one embodiment of the present invention, the functional elements may also be placed in different regions according to their height characteristics. At this time, the first region, the second region and the third region respectively correspond to different height ranges; the height of the first functional element is within the height range corresponding to the first area, and the height of the second functional element is within the height range corresponding to the second area; the height of the third functional element is within the corresponding height range of the third area. Therefore, the flexibility of the height design of the power shell can be improved, different shell heights can be formed conveniently according to different heights of functional elements in different areas, and therefore the power shell can be better matched with a refrigerating device.
It is understood that in other embodiments of the present invention, any two or three of the first region, the second region and the third region may correspond to the same height range; that is, any two or three of the first region, the second region, and the third region may also house functional elements having the same height.
In one embodiment of the present invention, the first functional element may include: the transformer is placed in the first area; the second functional element may include: the frequency converter is placed in the second area; the third functional element may include: the compressor and the fan, i.e., the compressor and the fan, are placed in the third area.

In an embodiment of the present invention, on the basis of the independent air path structure of the power pack, the structure of the power pack may further include the position structure characteristics of the air inlet and the air outlet, and the air cooling effect is further improved by the positions of the air inlet and the air outlet. Preferred implementations include any one or more of the following four position implementations:
the position implementation mode is as follows: and the position of the third air inlet and the position of the first air inlet form a horizontal position difference.
In the first implementation mode, a position difference is formed between the first air inlet of the outer shell and the third air inlet of the inner shell in the horizontal direction, so that the air stroke of the air from the outside to the third air inlet through the first air inlet is increased, the air resistance is reduced, and the liquid water in the air is prevented from entering the power pack.
The position implementation mode is as follows: the position of the fourth air inlet and the position of the second air inlet form a horizontal position difference;
in this implementation, the second air intake of outside casing and the fourth air intake of inside casing form the position difference in the horizontal direction of equipment for wind gets into the fourth air intake through the second air intake slope from the outside, thereby has increased the wind range, has reduced the windage, and is favorable to preventing the liquid water in the wind to get into the power package.
Position implementation mode three: the third air inlet is higher than the first air inlet;
in this implementation, the third air inlet of the inner casing is higher than the first air inlet of the outer casing, that is, a position difference is formed in the vertical direction of the equipment, so that the air upwards reaches the third air inlet from the outside through the first air inlet, the air stroke is increased, the wind resistance is reduced, and the liquid water in the air is prevented from entering the power pack.
The position implementation mode is four: the position of the fourth air inlet is higher than that of the second air inlet.
In this implementation, the fourth air intake of inside casing is higher than the position of the second air intake of outside casing, forms the position difference on the vertical direction of equipment promptly for wind passes through second air intake from the outside and upwards reaches the fourth air intake, thereby has increased the wind path, has reduced the windage, and is favorable to preventing the liquid water in the wind to get into the power package.
In one embodiment of the invention, the four position implementation modes are combined for use, so that air enters from two sides of the power pack, and the air arrives at the inner shell from the outer shell in an obliquely upward mode, the air course between the outer shell and the inner shell is increased, the wind resistance is reduced, and liquid water in the air is effectively prevented from entering the power pack.
In an embodiment of the present invention, the second air outlet on the inner casing is higher than the first air outlet on the outer casing, so as to facilitate air outlet.
In an embodiment of the present invention, in addition to the structure of the individual air path of the power pack, in order to increase the wind path between the outer casing and the inner casing and reduce the wind resistance, a space may be formed between the first side surface body and the second side surface body. Correspondingly, in order to prevent the air communication between the air inlet and the air outlet, the first side surface body and/or the second side surface body comprises a partition part, the partition part divides the space into a first space, a second space and a third space which are not communicated with each other, the third air inlet and the first air inlet are communicated with the first space, the first air outlet and the second air outlet are communicated with the second space, and the fourth air inlet and the second air inlet are communicated with the third space.
Wherein, if the first flank body and the second flank body each include a partition thereon, the partition of the first flank body is engaged with the partition of the second flank body.
In an embodiment of the present invention, on the basis of the single air path structure of the power pack, the regions surrounded by the inner casing may be separated by partitions, and in this case, the inner casing includes a first partition partitioning the first region and the third region, and a second partition partitioning the second region and the third region; in order to enable wind energy to flow in the area of the inner shell, the first partition plate and the second partition plate are respectively provided with more than one ventilation opening at the position far away from the second side surface body, so that the wind enters from two sides of the power pack, respectively cools elements in the first area and the second area, then reversely enters the third area, cools the elements in the third area, and is discharged from the middle of the power pack.
In the above embodiment of the present invention, the first side body and the second side body are located on the same side of the power pack, that is, all the air inlets and the air outlets on the power pack are located on the same side of the power pack, so that the installation complexity of the power pack can be reduced.
In an embodiment of the present invention, in order to reduce an influence of the impurities or moisture possibly carried in the wind on the intake wind, a filter screen is disposed on any one or more of the first intake vent, the second intake vent, the third intake vent, and the fourth intake vent, so as to filter the impurities or moisture possibly carried in the wind.
In one embodiment of the present invention, in order to facilitate replacement of the fan in the power pack, that is, when the fan is included in the third functional element, a fixing plate may be disposed on the second side surface body at a position corresponding to the second air outlet, and the fan is fixedly connected to the fixing plate. During subsequent maintenance, the fan is disassembled by conveniently disassembling the fixing plate, and the fan is installed by conveniently installing the fixing plate. In one embodiment of the present invention, the fixing plate may be an aluminum plate.
Since the different types of compressors have different heights, in one embodiment of the present invention, the top of the outer housing may have a protrusion in a position corresponding to the third region, so that the power pack may house a higher height compressor.
In order to facilitate the assembly of the power pack, the power pack may include a lifting lug, by which the power pack is lifted or moved. In one embodiment of the invention, more than one rotatable lifting lug may be placed on the inner housing. By adopting the structure, when the lifting lug is not needed to be used, the lifting lug can be rotated into the inner shell and is in a retracted state, and when the lifting lug is needed to be used, the lifting lug can be rotated out and is in a use state. Compared with the method of using the fixed connecting lifting lug on the outer shell, the method of additionally arranging the rotatable lifting lug on the inner shell can enable the structure of the power pack to be more compact and the flexibility to be stronger. Moreover, the rotatable lifting lug is additionally arranged on the inner shell, and holes do not need to be drilled on the outer shell, so that the problem that external rainwater enters the power pack from the holes of the outer shell can be solved.
Bolts may be used in the power pack and may be electrically charged. In order to prevent the bolt from contacting the shell, the bolt is disposed in the insulating plate, and the thickness of the insulating plate needs to satisfy the requirement that the bolt is not exposed from the insulating plate, so as not to contact the shell. In one embodiment of the present invention, in order to further simplify the structure of the power pack, the thickness of the insulating plate used in the power pack may be reduced. The realization mode comprises the following steps: an insulating plate is arranged at the bottom of the inner shell, and more than one concave part is formed between the insulating plate and the bottom of the inner shell; the insulating plate is connected with more than one bolt, and the bottom of the more than one bolt is positioned in the concave part and is not contacted with the bottom of the inner shell. Therefore, through the design of the concave part, the bolt can be ensured not to be contacted with the shell, and the used insulating plate material and thickness can be reduced.
In this embodiment of the present invention, there are various ways of forming one or more recesses between the insulating plate and the bottom of the inner case, for example, a thickening layer connected to the insulating plate is formed on the bottom of the inner case, but the thickening layer is formed only in a region other than a position region where the bolt is exposed, the position region where the bolt is exposed is formed as the recess, and the bottom of the bolt is located in the recess and does not contact the bottom of the inner case.
An embodiment of the invention further provides an air conditioning device, which comprises the power pack and a refrigerating device, wherein the power pack is connected with the refrigerating device and provides power for the refrigerating device. The power may include electric power and compression power.
In one embodiment of the invention, the air conditioning device is an in-vehicle air conditioning device.
In one embodiment of the invention, the power pack is connected with the refrigerating device in a split mode. Therefore, the power pack and the refrigerating device can be arranged at different positions without being integrally arranged, the requirement of the installation position is lowered, and the installation flexibility of the air conditioner is improved.

In this way, the power pack 1401 and the refrigerating device 1402 can be installed at different positions without being integrally placed, so that the requirement of the installation position is reduced, and the installation flexibility of the air conditioner is improved. For example, the installation location on the roof of the vehicle is limited, and it may not be possible to place the integrally connected power pack 1401 and cooling device 1402. Since the power pack 1401 and the refrigeration device 1402 are connected in a split manner, the power pack 1401 can be installed in one available space position of the roof, and the refrigeration device 1402 can be installed in another available space position of the roof, so that the installation flexibility is improved.

Referring to fig. 17, an embodiment of the present invention further provides a method for manufacturing a power pack, including:
step 1701: forming a housing.
Step 1702: the power pack comprises a power pack body, a first area, a second area and a third area.
In this step, the first area and the second area are respectively located on two sides of an area defined by the shell, and the third area is located between the first area and the second area.
Step 1703: placing a first functional element in the first area; placing a second functional element in the second area; a third functional element is placed in the third area.
Step 1704: and air ports are respectively formed on the shell at the position corresponding to the first area, the position corresponding to the second area and the position corresponding to the third area.
It can be seen that, in the method of the embodiment of the present invention, the area surrounded by the housing of the power pack is divided, the functional elements of the power pack are placed in different areas, and the air outlets are respectively located in different areas of the housing, that is, in positions corresponding to the first area, the second area and the third area, that is, the external air enters and exits from the air outlets corresponding to the three areas of the power pack. The functional elements are placed in the sub-regions, and the power pack can be cooled more effectively by the aid of the independent air path guiding mode of air inlet and air outlet in the sub-regions. In addition, the independent air path of the power pack is not limited by the whole air path of the air conditioner, and the use flexibility of the power pack is improved.
The process of forming the tuyere in the above step 1704 may include:
forming a structure with air inlet at two sides and air outlet at the middle, specifically, forming air inlets at the position corresponding to the first area and the position corresponding to the second area on the shell respectively, and forming an air outlet at the position corresponding to the third area;
or,
and forming a structure with air outlet at two sides and air inlet in the middle, specifically, forming air outlets in positions corresponding to the first area and the second area on the shell respectively, and forming air inlets in positions corresponding to the third area.
In other embodiments of the present invention, the method for manufacturing the power pack may further include any one or more of layout of the power pack air passage, layout of the lifting lug, layout of the bolt position, and the like.
The following describes the process of manufacturing the power pack in a preferred embodiment of the present invention in detail by taking the structure of forming air inlets at both sides and air outlet at the middle of the power pack as an example. Referring to fig. 18, the process includes:
step 1801: forming an inner housing and an outer housing covering the inner housing.
In this step, an inner case of a cubic structure and an outer case of a cubic structure may be formed.
And further, can also form multistage arc structure in the both sides of outside casing and inside casing to strengthen visual effect and reduce the whole height of power package. And, this multistage arc structure of power package can also form better matching with refrigerating plant in the appearance.
And, further, in order to secure a better covering effect, the shape of the outer case may be made in a form of surrounding the inner case entirely.
Such as an inner housing and an outer housing formed as shown in fig. 1.
Step 1802: the power pack is characterized in that the area enclosed by the inner shell of the power pack is divided into a first area, a second area and a third area.
In this step, the first area and the second area are respectively located on two sides of an area enclosed by the inner shell, and the third area is located between the first area and the second area.
Step 1803: placing a first functional element in the first area; placing a second functional element in the second area; a third functional element is placed in the third area.
In this step, the functional elements can be placed in different regions according to the temperature characteristics of the functional elements.
For example, the high-temperature element with relatively high temperature is placed in the third area, and further the high-temperature element can be placed at a position close to the air outlet in the third area, so that air entering the first area and the second area from the air inlets at two sides is converged into the third area, and the high-temperature element in the third area is intensively cooled and then discharged, and further the cooling effect on the functional element of the power pack is improved. And through the processing of this step, in the follow-up cooling process, the both sides air inlet is at first cooled off the functional element that the temperature is lower relatively in first region and second region, then cools off the high temperature component that the temperature is higher in the third region again to can maintain the higher difference in temperature between wind and the functional element that needs to cool off, also further improve the cooling effect to the functional element in the power package.
In this step, the functional elements can be placed in different areas according to the height characteristics of the functional elements. At this time, the first region, the second region and the third region respectively correspond to different height ranges; the height of the first functional element is within the height range corresponding to the first area, so that the first functional element is placed in the first area; the height of the second functional element is within the height range corresponding to the second area, so that the second functional element is placed in the second area; the third functional element has a height within a height range corresponding to the third area and is therefore placed in the third area. Therefore, the flexibility of the height design of the power shell can be improved, different shell heights can be formed conveniently according to different heights of functional elements in different areas, and therefore the power shell can be better matched with a refrigerating device in height.
Step 1804: on the first side surface body of the outer housing, a first air inlet is formed at a position corresponding to the first region, a second air inlet is formed at a position corresponding to the second region, and a first air outlet is formed at a position corresponding to the third region.
Step 1805: on a second side surface body of the inner housing joined to the first side surface body, a third air inlet is formed at a position corresponding to the first region, a fourth air inlet is formed at a position corresponding to the second region, and a second air outlet is formed at a position corresponding to the third region.
Through the processing of the steps 1804 and 1805, the design of the air path for air inlet at the two sides and air outlet at the middle of the power pack is realized.
In order to increase the wind distance between the outer casing and the inner casing, reduce the wind resistance, and prevent the liquid water in the wind from entering the interior of the power pack, the processing in the steps 1804 and 1805 may further include any one or more of the following arrangements:
the position distribution mode is I, and a horizontal position difference is formed between the position where the third air inlet is arranged and the position of the first air inlet;
the position distribution mode is two, and the position of the third air inlet is higher than that of the first air inlet;
the position distribution mode is III, and a horizontal position difference is formed between the position where the fourth air inlet is arranged and the position where the second air inlet is arranged;
and the position arrangement mode is four, and the position of the fourth air inlet is higher than the position of the second air inlet.
In addition, in the processing of this step, the positions of the outlets may be arranged as follows: the second air outlet on the inner shell is arranged at a position higher than the first air outlet on the outer shell. The air outlet is more favorable for air outlet in the position setting mode.
Step 1806: a spacing space is formed between the first side body and the second side body.
Step 1807: the partition space is divided into a first partition space, a second partition space and a third partition space which are not communicated with each other, the third air inlet and the first air inlet are communicated with the first partition space, the first air outlet and the second air outlet are communicated with the second partition space, and the fourth air inlet and the second air inlet are communicated with the third partition space.
In this step, the implementation of the separation of the spacing spaces is as follows: a partition is formed on the first side surface body and/or the second side surface body, and the space is partitioned by the partition part. When the first side surface body and the second side surface body are both provided with the separating parts, the separating parts of the first side surface body are required to be jointed with the separating parts of the second side surface body.
The processing from step 1806 to step 1807 can prevent the air inlet from communicating with the air outlet.
Step 1808: more than one rotatable lifting lug is arranged on the inner shell.
Step 1809: an insulating plate is placed at the bottom of the inner case, and one or more recesses are formed between the insulating plate and the bottom of the inner case.
In this step, the forming of the one or more recesses may include: the bottom of the inner casing is formed with a thickened layer connected to the insulating plate, the thickened layer is formed only in the region except the position region where the bolt is exposed, the position region where the bolt is exposed is formed as the above-mentioned recess, and the bottom of the bolt is located in the recess and does not contact the bottom of the inner casing.
Step 1810: more than one bolt is connected to the insulating plate, and the bottom of each bolt is arranged in a space of the concave part which is not contacted with the bottom of the inner shell.
Step 1811: the outer housing is engaged with the inner housing.
In the flow shown in fig. 18, after step 1801 and before step 1811, other manufacturing processes may be performed, such as forming a first partition separating the first region and the third region on the inner housing, and a second partition separating the second region and the third region; and more than one vent is respectively arranged on the first clapboard and the second clapboard far away from the second side body. For another example, a filter screen is placed on any one or more of the first air inlet, the second air inlet, the third air inlet and the fourth air inlet; for another example, when the third functional element includes the fan, a fixing plate, such as an aluminum plate, is disposed on the second side surface body corresponding to the second air outlet, and the fan is fixedly connected to the fixing plate, so as to facilitate subsequent replacement and maintenance.
It should be noted that, the execution sequence of each step in the flow shown in fig. 18 is not strict, and is only for convenience of describing the divided steps, for example, the processing in step 1808 may be executed at any time after step 1801 and before step 1811, and for example, the processing of the air path arrangement described in steps 1804 to 1805 may be executed after the processing of isolating the inlet air from the outlet air described in steps 1806 to 1807, and the like.
It should be noted that the manufacturing process described in fig. 18 is exemplified by forming a structure in which air is supplied to both sides of the power pack and air is discharged from the middle of the power pack. It is understood that, similarly, in other embodiments of the present invention, the structures of the two side air outlets and the middle air inlet of the power pack may be formed in the same manner, and other structures described in fig. 18 may also be formed, such as the above-mentioned partition spaces, partition plates, partitions, recesses, lifting lugs, and the like.

In addition, the independent air path of the power pack is not limited by the whole air path of the air conditioner, and the use flexibility of the power pack is improved.
