This invention relates to the field of lithium battery heat dissipation technology, specifically disclosing a heat dissipation device for lithium battery packs, comprising a support plate and a top plate. The support plate and the top plate are arranged longitudinally symmetrically in parallel. Multiple sets of coaxially corresponding mounting holes 1 and 2 are arrayed along the length direction on their opposite end faces. Hollow sealing rings are fixedly installed on the inner walls of both mounting holes 1 and 2. Two symmetrically arranged side plates 1 and 2 are fixedly connected to the two side edges of the support plate and the top plate. The support plate, the top plate, the side plates 1 and 2 together form a cavity structure for accommodating the lithium battery pack and heat dissipation components. Several fan support frames are arrayed along the length direction of the side plates 1 facing the inner side of the cavity, and each of the fan support frames is equipped with a corresponding heat dissipation fan. The air outlet direction of the heat dissipation fan faces the inner cavity. This invention addresses the problem of the single heat dissipation function of lithium batteries.

The utility model relates to a hydrogen production power supply cabinet, comprising a common unit cabinet which is suitable for arranging an output busbar; and a plurality of conversion unit cabinets, wherein the interior of each conversion unit cabinet is suitable for being provided with a power conversion module. The plurality of conversion unit cabinets are adjacently arranged on at least one transverse side of the common unit cabinet with the common unit cabinet, and comprise at least two conversion unit cabinets which are longitudinally arranged on the same transverse side of the common unit cabinet; and the output busbar only extends in the common unit cabinet along the transverse direction and is connected with the power conversion module in each conversion unit cabinet. Compared with a structure in which unit cabinets are arranged in a row in the prior art, the hydrogen production power supply cabinet has the advantages that the transverse space of the whole hydrogen production power supply cabinet can be greatly reduced, the output busbar can be only arranged in the shared unit cabinet, the length and the use amount of the output busbar are saved, and the heat dissipation efficiency and the heat dissipation cost of the output busbar are improved.

This invention relates to the field of drinking water equipment control technology, specifically disclosing a control method and device for drinking water equipment, a storage medium, and the drinking water equipment itself. The drinking water equipment includes a refrigeration device. The control method includes: acquiring temperature information of the environment in which the drinking water equipment is located; controlling the refrigeration device to perform an ice-making operation in a first ice-making mode based on the temperature information; and, after the ice-making operation is completed, if no cold water or ice-retrieving command is received within a first preset time period, controlling the refrigeration device to operate in a second ice-making mode. The rotational speed of the refrigeration device in the second ice-making mode is lower than that in the first ice-making mode, thereby reducing the refrigeration power consumption and cost of the drinking water equipment and improving the user experience.

This utility model relates to the field of mold processing technology and discloses a mold for the internal reinforcement structure of a blow molding pallet. It includes a support frame, a reinforcing mechanism at the top of the support frame, a molding assembly at the top of the inner wall of the support frame, and a blow molding assembly at the top of the molding assembly. The reinforcing mechanism includes a fixed mold, the bottom of which is fixedly connected to the top of the support frame. Multiple reinforcing grooves are formed on the bottom of the inner wall of the fixed mold, and multiple foot grooves are formed on the front and rear sides of the bottom of the inner wall of the fixed mold. Multiple flared surfaces are also formed on the inner wall of the fixed mold. In this utility model, a telescopic rod causes the moving mold to slide and close the mold, and air needles blow air to make the raw material adhere to the inner wall of the mold. The reinforcing grooves and foot grooves on the fixed mold strengthen the product during shaping. The flared surfaces increase strength and area, facilitating demolding. The structure ensures stable operation of the equipment, increases the strength of the pallet during molding, improves load-bearing capacity and durability, and meets the requirements.
