This utility model relates to the field of dual dynamic driver headphone technology, aiming to solve the problems of existing push-pull dual dynamic driver headphones where a single dynamic driver unit is the main source of sound, resulting in limited dynamic range and output efficiency, and parallel dual dynamic driver headphones where the multi-cavity design leads to increased size and weight, and discomfort when worn. The present invention provides a rear-mounted dual dynamic driver headphone, including a housing, within which a first dynamic driver unit and a second dynamic driver unit are installed, arranged back-to-back. The space formed between the diaphragm side of the first dynamic driver unit and the housing is the front cavity of the first dynamic driver unit, and the space formed between the diaphragm side of the second dynamic driver unit and the housing is the front cavity of the second dynamic driver unit. The space between the two dynamic driver units is a shared rear cavity. The front cavities of the first and second dynamic driver units are connected by an acoustic channel. A sound outlet is provided on the housing, and the front cavity of the second dynamic driver unit is connected to the sound outlet. This utility model has significant improvements in sound quality, wearing comfort, and production efficiency.

This invention discloses a siphon heat pipe radiator for an outdoor unit of an air conditioner, relating to the field of energy-saving air conditioning. It includes an evaporator and a condenser connected together. The evaporator is mounted on the outdoor unit of the air conditioner. The condenser includes a manifold connected to the outlet of the condenser. A first partition plate is arranged inside the manifold along a first direction and is connected to the evaporator. The first partition plate divides the manifold into an upper chamber and a lower chamber, which are sequentially distributed along a second direction. A connecting area is formed between the side of the first partition plate away from the evaporator and the side wall of the manifold, connecting the upper and lower chambers. Through holes are formed on the first partition plate. A proximal region, a middle region, and a distal region are formed on the first partition plate along the first direction, with the density of through holes corresponding to the proximal, middle, and distal regions increasing sequentially. This invention solves the problems of gas-liquid entrainment and uneven vapor distribution.

This utility model relates to the field of battery pack technology, and discloses a front panel assembly and a battery pack. The front panel assembly includes: a panel body, on which at least one mounting cavity and a connecting post are provided, the connecting post extending away from the panel body and forming a bearing surface; a baffle, which can be opened and closed to cover the mounting cavity and has a locking hole aligned with the connecting post, the locking hole penetrating the baffle, and having a limiting surface flush with the bearing surface within the locking hole; and a locking member, which is detachably inserted into the locking hole and connected to the connecting post, and the head of the locking member simultaneously abutting against both the bearing surface and the limiting surface. The advantages of this utility model are that it is easy to maintain, structurally stable, and provides good protection.

This application provides a top cover for a battery casing, a battery casing, and a battery cell, relating to the field of battery technology. The top cover of the battery casing includes a cover plate and at least one support. At least one support is disposed on the cover plate. A channel extending along a first direction is formed between the support and the cover plate. At least one support member is disposed within the channel. The support and at least one support member are an integral structure. In the event of thermal runaway, the support member can effectively maintain the structural shape of the channel, thereby limiting excessive compression or blockage of the exhaust channel, and ensuring that the pressure relief mechanism can properly release pressure, thus reducing the risk of internal pressure buildup and explosion.
