Description

Technical Field

[0001] The utility model belongs to the field of distributed energy storage equipment and relates to a partition cover of a liquid cooling water machine. Background Art

[0002] The optimal operating temperature range of the lithium iron phosphate battery system of distributed liquid-cooled energy storage products is generally between 20℃-30℃. Too high or too low temperature will affect the performance of the battery system, so the thermal management of the battery system is crucial to the performance of the product. At present, the thermal management of the liquid-cooled energy storage battery system mainly adopts the cooling or heating method of the liquid chiller. The liquid chiller and the battery PACK are connected through the liquid cooling pipeline, that is, the liquid chiller outlet connection pipeline corresponds to the battery PACK inlet, and the battery PACK outlet is connected to the liquid return port of the liquid chiller through the pipeline; when the battery temperature is high, the liquid chiller starts the cooling function, and the water machine circulation pump sends the low-temperature coolant from the battery PACK inlet through the pipeline into the PACK for heat exchange to achieve cooling. When the PACK battery cell temperature reaches the optimal range, the liquid chiller stops operating until the temperature deviates from the optimal range again and then starts again; when the PACK needs to be heated, the liquid chiller heating function is started, and the coolant temperature is increased by heating to heat the battery PACK to keep it at a normal working temperature.

[0003] The liquid chiller is a power device, and its working process will generate a certain amount of heat. This heat is generally dissipated by natural air cooling. If there is no reliable heat insulation between the liquid chiller and the battery PACK, this heat will have a significant impact on the operating temperature of the battery PACK.

[0028] The utility model is further described in detail below with reference to the accompanying drawings:

[0029] like Figure 1 , 3 As shown, the utility model provides a liquid cooling water machine partition cover, including an upper plate cover 1, a lower plate cover 2, a water machine guide rail 3 and EVA plugging cotton 4. The lower plate cover 2 is arranged at the lower end of the upper plate cover 1. In addition, the lower plate cover 2 is a C-shaped structure, and its two ends are fixedly connected to the upper plate cover 1, specifically fixed by rivets. The water machine guide rail 3 is arranged in the lower plate cover 2, and the EVA plugging cotton 4 is arranged on one side of the lower plate cover 2.

[0030] A first fixing plate 11 and a second fixing plate 12 are provided at both ends of the upper plate cover 1 away from the EVA sealing cotton 4; the first fixing plate 11 is integrated with the upper plate cover 1, and the second fixing plate 12 is fixedly connected to the upper plate cover 1 through a connecting member, wherein the connecting member is a bolt or a screw. A water machine pipe avoidance hole 111 and a liquid chiller partition cover fixing hole 112 are provided on the side of the first fixing plate 11 away from the second fixing plate 12. The water machine pipe avoidance hole 111 is semi-elliptical, and two liquid chiller partition cover fixing holes 112 are provided on both sides of the water machine pipe avoidance hole 111; the second fixing plate 12 is also provided with a water machine pipe avoidance hole 111 and a liquid chiller partition cover fixing hole 112 on the side away from the first fixing plate 11. It should be noted that the water machine pipe avoidance hole 111 and the liquid chiller partition cover fixing hole 112 of the second fixing hole 12 have the same structure, shape and size as the water machine pipe avoidance hole 111 and the liquid chiller partition cover fixing hole 112 of the first fixing hole 11. Figure 2 As shown, a limiting plate 13 is provided on one side of the upper plate cover 1 close to the lower plate cover 2 and close to one end of the EVA sealing cotton 4.

[0031] The lower plate cover 2 includes a first plate cover, a second plate cover and a third plate cover. The first plate cover and the second plate cover are arranged opposite to each other. The third plate cover is arranged at the lower end of the upper plate cover 1, and its two sides are connected to the first plate cover and the second plate cover. At the same time, the axis of the first plate cover is parallel to the axis of the second plate cover, and the axis of the first plate cover is perpendicular to the axis of the third plate cover. A first connecting plate 21 is arranged on the side of the first plate cover close to the first fixing plate 11, and a second connecting plate 22 is arranged on the side of the second plate cover close to the second fixing plate 12. The first connecting plate 21 and the second connecting plate 22 are provided with water machine installation fixing holes 211.

[0032] The water machine guide rail 3 is installed at the angle between the first plate cover and the third plate cover, and at the angle between the second plate cover and the third plate cover. At the same time, the water machine guide rail 3 is provided with a chamfer at one end away from the EVA plugging cotton 4, which is convenient for the installation of the liquid chiller. The gap between the air outlet of the liquid chiller and the upper plate cover 1 and the lower plate cover 2 is blocked by the EVA plugging cotton 4, so that the gas does not flow into the liquid chiller during the heat dissipation process of the liquid chiller. In addition, the upper plate cover 1, the first plate cover, the second plate cover and the third plate cover are provided with insulation cotton on the side away from the water machine guide rail 3. The device has a liquid chiller partition cover with the same airflow as the outside world, so it is sprayed before installation. A method for installing a liquid chiller partition cover is: first fix the second fixing plate 12 with the upper plate cover 1 by bolts, then install the water machine guide rail 3 in the lower plate cover 2 by bolts, then install the EVA plugging cotton between the first plate cover and the third plate cover, and finally fix the upper plate cover 1 to the lower plate cover 2 with rivets.

[0033] like Figure 4 As shown, the liquid chiller partition cover is installed at the bottom of the energy storage cabinet, and the water machine guide rail 3 is provided with a chamfered end as the front end, and the air inlet louver filter assembly is installed at the front end to the air inlet, specifically: louver and filter. In order to increase the air intake, the louver increases the inlet area; a sealing strip is affixed to the louver joint between the liquid chiller partition cover and the air inlet to ensure that the air intake does not leak out; a waterproof louver air outlet cover is installed between the rear side of the liquid chiller partition cover and the air outlet, and its main function is to waterproof the liquid chiller during standby period. At the same time, the liquid chiller partition cover and the waterproof louver air outlet cover are also connected by sealing; EVA sealing cotton 4 is used at the rear end of the liquid chiller partition cover. At this time, after the liquid chiller is installed, the airflow of its heat dissipation can be guaranteed to be smooth, that is, natural wind enters the liquid chiller from the right air inlet through the air inlet louver filter assembly through the action of the liquid chiller heat dissipation fan, and is discharged from the left waterproof louver air outlet cover after heat exchange.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
