This invention discloses a heat dissipation structure for a thermal power plant transformer, including a body with a storage compartment inside, and a transformer protective shell inside the storage compartment. The transformer protective shell has an air intake grille, and a mounting component is located inside the protective shell. The mounting component has a vertically penetrating mounting groove, and a suitable transformer component plate is nested inside the mounting groove. The lower side of the mounting groove is spaced apart from the transformer shell, and the lower side of the transformer component plate has multiple semi-through slots. This invention solves the problems of poor heat dissipation in traditional thermal power plant transformers, heat accumulation on the back of the transformer component plate leading to overheating and malfunction, and reduced component lifespan.

The utility model relates to synthetic leather technical field especially relates to a kind of skin-friendly breathable synthetic leather.It solves the technical problem that traditional synthetic leather skin-friendly and poor breathability, the utility model utilizes the preliminary breathability structure of rectangular array arc-shaped protrusion, point broken line connection and micro-vent hole formed by surface layer setting, utilizes the point broken line only connected adjacent arc-shaped protrusion edge area of setting, reduce the obstruction to breathable channel, while hollow cavity and micro-vent hole orthographic projection one-to-one correspondence, ensure that air accurately and smoothly circulate, and in independent honeycomb hollow cavity structure increases air circulation space, through the structure for the setting of multilevel breathable channel, the effective breathability of synthetic leather can be realized.

The utility model discloses a boat structure, which comprises a supporting frame body and a plurality of supporting pieces fixedly arranged on the supporting frame body and arranged in a linear array, a bearing gap for accommodating a wafer is arranged between two adjacent supporting pieces, and the bearing gap comprises a mounting gap and a flow expanding gap. According to the boat structure, the flow expansion gaps are further arranged in the bearing gaps on the supporting frame body, and the center distance between adjacent wafers is increased, so that the circulation path of process gas is prolonged, the contact time of the process gas and the wafers is prolonged, the local gas concentration difference is reduced, the diffusion of the process gas is more uniform, and the yield of the wafer is improved. And the oxidation uniformity can be effectively improved by further reacting with the wafer, and the surface processing quality of the wafer is improved.

This utility model relates to the field of communication device technology, specifically a communication device with a multi-channel splitting structure. It includes a communication device body, a tripod fixedly connected to the bottom of the body, an air inlet at the bottom of the outer shell, a dustproof net fixedly connected to the air inlet, and heat dissipation vents on both sides of the top of the body. A spectrum monitoring sensor is installed on the left side of the body and electrically connected to a processor inside the device. A storage box is fixedly connected to the rear side of the top of the tripod. This design allows the router to tilt at the bottom using the tripod, increasing the airflow space. Air enters the router through the air inlet, carrying away heat, and is expelled through the heat dissipation vents, achieving effective heat dissipation. Simultaneously, the dustproof net protects the air inlet and heat dissipation vents from dust during use.

This application provides a single-cell battery and a battery pack. The single-cell battery includes a cell, a casing, an explosion-proof valve, terminals, and a cell support plate. The terminals are disposed on a first side wall of the casing, and the explosion-proof valve is disposed on a second side wall of the casing. The first and second side walls are located on different sides of the casing. The cell is located inside the casing, and the cell support plate is located between the cell and the second side wall. The cell support plate includes a first support portion and at least one second support portion. Along the length direction of the cell support plate, the second support portion and the first support portion are arranged sequentially. The orthographic projection of the first support portion on the second side wall at least partially overlaps with the explosion-proof valve, and the orthographic projection of the second support portion on the second side wall is offset from the explosion-proof valve. The maximum thickness of the second support portion is greater than the maximum thickness of the first support portion. This single-cell battery has high safety in the event of thermal runaway.
