4results about How to "Uniform cooling temperature" patented technology

The utility model discloses an energy storage battery pack which comprises a lower box body, a battery module, a sealing cover, an upper cover, an explosion-proof valve and a smoke exhaust pipe, the battery module is arranged in the lower box body, the upper cover covers the top of the lower box body, a plurality of wire passing holes are formed in the sealing cover, and the explosion-proof valve is arranged on the upper cover. The sealing cover is arranged on the lower box body in a sealing manner, and pole pieces on the battery modules penetrate through the wire passing holes, so that an upper cabin and a lower cabin are formed in the battery pack; an anti-explosion valve is arranged on the sealing cover and connected with a smoke exhaust pipe penetrating through the upper cover. The battery pack has the advantages that the battery module in the lower cabin is soaked in the cooling liquid, so that the heat dissipation temperature of the battery module is uniform, the risk of thermal runaway of the battery pack is greatly reduced, and the manufacturing cost of the battery pack is reduced as the non-insulating cooling liquid can be filled in the lower cabin.

A proton exchange membrane fuel cell metal bipolar plate flow field system belongs to the field of fuel cell technology. The bipolar plate is connected by an anode monopolar plate, a cathode monopolar plate and a middle partition to form a three-layer structure, which respectively forms a fuel flow field, an oxidant flow field, and a coolant flow field II and a coolant flow field I. The above-mentioned proton exchange membrane fuel cell metal bipolar plate flow field system has the advantages of small pressure drop of multi-channel serpentine flow channels and good gas diffusion of interdigital flow channels in the anode flow field; the cathode flow field retains the advantages of convenient exhaust and low pressure drop of multi-channel serpentine flow channels, and the convex hull makes the oxidant flowing in the flow channel diffuse to the diffusion layer to increase the battery power; the dual coolant flow fields with two groups of coolant flowing in opposite directions make the coolant cooling temperature more uniform, and the consistency of the working area of ​​the fuel cell is better, which greatly improves the thermal control ability of the fuel cell and provides a guarantee for the safety of the fuel cell.

The energy storage battery cooling plate of this invention features inlet and outlet water channels arranged laterally within the harmonica tube of the cooling plate. On the upper end of the cooling plate, facing both sides, are provided inlet holes for each inlet channel and outlet holes for each outlet channel. The inlet holes are a row of through holes leading to one side of the cooling plate, and the outlet holes are a row of through holes leading to the other side. A long strip-shaped return valve is located at the lower end of the cooling plate, forming a return channel between the return valve and the spacer plate. The internal space of the upper frame is divided by the cooling plate into an inlet water collection chamber and an outlet water collection chamber, respectively connected to the inlet and outlet of the cooling power system. The two ends of the upper frame are sealed. The parallel arrangement of the inlet and outlet water collection chambers and the multiple independent single-circulation cooling water channels of this invention solve the problem of uneven temperature distribution in the horizontal and vertical directions of the cooling plate. It is reliable in operation, simple in structure, and significantly reduces the total power requirements of the cooling power system, thus greatly reducing investment.
