Description
Technical Field
The utility model belongs to a new energy battery cooling device, in particular to direct cooling plate.
Background
The refrigerant passes through the inlet and outlet channels of the battery cooling plate to perform heat exchange operation. The battery cooling plate is formed by welding a base plate and a runner plate through a brazing process. Meanwhile, the flow channel plate is punched to form a flow channel space through which the refrigerant passes.
Therefore, it is necessary to punch a runner plate capable of uniformly distributing the refrigerant flow and high in heat exchange efficiency, and most of the existing designs are the width of a runner loop and a runner, and then the refrigerant flow of each battery module is distributed, so that the pressure drop is large, the heat exchange efficiency is low, and the temperature uniformity among the battery modules is poor.
Therefore, a refrigerant flow distribution design with higher heat exchange efficiency is needed, and what kind of design is adopted by the flow passage becomes a problem to be solved urgently at present.
Disclosure of Invention
The utility model aims to provide a: the direct cooling type cooling plate flow channel for the battery can reduce internal resistance, optimize temperature uniformity among battery modules and improve heat exchange efficiency.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the utility model provides a battery direct cooling formula cooling plate runner, includes runner plate and base plate, runner plate and base plate fixed connection form the runner, its characterized in that: the flow channels on the flow channel plate are symmetrical along the center line of the whole flow channel, and two side flow channel openings are distributed on two sides of the middle flow channel opening, wherein the distance between the middle flow channel openings is non-equidistant, the distance between the flow channel openings close to the middle is small, and the distance between the flow channel openings close to the two sides is larger.
The middle runner port is an inflow runner or an outflow runner, and the two runner ports are corresponding outflow runners or inflow runners.
The number of the middle runner ports is 1 or a plurality of; the number of the flow passage openings at the two sides is multiple of that of the flow passage opening at the middle.
The runner is integrally formed by adopting a processing mode of stamping, hydraulic pressure or extrusion.
The utility model has the advantages that: the utility model discloses a design symmetrical formula runner on the runner board, and the interval non-equidistance of middle runner, middle secret, both sides are sparse. In the process that the refrigerant flows in the flow channel, the function of the symmetrical flow channel is to ensure that the flow of the refrigerant is completely uniform on two sides of the module, and the function that the flow channel is denser at the inlet than the flow channel at the outlet is to optimize the temperature uniformity among the battery modules, so that the heat exchange efficiency of the refrigerant is optimized, and the flow resistance is greatly reduced. And the structure is simple, the processing is convenient, and the device is firm and reliable, and is particularly suitable for being used on a battery direct cooling plate.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-2, the present invention comprises a flow channel plate 1 and a base plate 2, wherein the flow channel plate 1 is provided with a punched protrusion, and the flow channel plate 1 and the base plate 2 are fixed together by welding to form a flow channel therebetween. On the flow channel plate 1, there are a middle flow channel port 3, two side flow channel ports one 4 and two side flow channel ports two 5. The distance between the middle runners 6 is not equal, the distance between the two sides close to the middle runner port is small, and the distance between the two sides close to the runner ports is larger. And the whole flow passage is symmetrical along the center line of the flow passage.
The middle runner port 3 is an inflow runner or an outflow runner, and the runner ports on the two sides are corresponding outflow runners or inflow runners. The number of the middle runner ports is 1 or a plurality of; the number of the flow passage openings on the two sides is 2 times of that of the flow passage opening in the middle. The runner is integrally formed with the runner plate in a stamping, hydraulic or extrusion processing mode.
When the refrigerant flows in the flow channel, the refrigerant is characterized in that the temperature is higher when the pressure is high and the temperature is lower when the pressure is low due to the unequal-interval flow channel design. When the refrigerant enters the flow channel, more flow channels need to be arranged, and when the refrigerant reaches the vicinity of the outlet flow channel, the temperature of the refrigerant is reduced due to pressure loss, so that the flow channels can be arranged less to maintain the overall uniformity of the temperature of the battery. The unequal interval type flow channel design optimizes the cooling uniformity, prolongs the service life of the battery, improves the heat exchange efficiency of the direct cooling plate of the battery, simultaneously conveniently establishes a processing flow channel, strengthens the strength of the flow channel plate and improves the durability of the direct cooling plate.
