An efficient boiler steam exhaust silencer reliable in structure and durable comprises a silencer body, a supporting plate and a base used for achieving the overall supporting effect, the supporting plate is transversely installed on the base through a plurality of shock absorbers, and the silencer body is transversely and fixedly installed on the top of the supporting plate; the supporting plate comprises a steam inlet cylinder, a silencing cylinder and a steam outlet cylinder which are fixedly communicated in sequence, a steam inlet of the steam inlet cylinder is connected with a steam inlet flange through a steam inlet hose, a steam outlet of the steam outlet cylinder is connected with a steam outlet flange through a steam outlet hose, and the outer side of the silencing cylinder is sleeved with a heat exchange jacket used for cooling steam in the silencing cylinder. A cooling water inlet and outlet pipeline is fixedly connected to the heat exchange jacket, and a plurality of silencing plates are sequentially arranged in the steam outlet cylinder from one side of the silencing cylinder to one side of the steam outlet. By integrating the high-strength structural design and the multi-stage composite silencing technology, the efficient attenuation and low-resistance steam exhaust of steam exhaust noise are realized while long-term stable operation and durability are ensured.

The utility model relates to the technical field of batteries, in particular to a high-safety battery pack which comprises a box body, a whole pack explosion-proof valve and at least one layer of battery cells, each layer of battery cells is arranged in the box body and comprises a plurality of columns of battery cells which are sequentially arranged along a first preset direction, each column of battery cells comprises a plurality of battery cells which are sequentially arranged along a second preset direction; each battery cell is provided with a side cut corner, and a battery cell explosion-proof valve is arranged at the side cut corner of each battery cell; and in the first preset direction, an exhaust space is defined between the side tangent planes of the side tangent angles of any two adjacent battery cells in each layer of battery cells, so that an exhaust channel extending in the second preset direction is formed between any two adjacent columns of battery cells in each layer of battery cells. Therefore, the side corner is designed at the side part of the battery cell, so that the exhaust channel is formed, the exhaust effect of the battery pack is improved, the thermal runaway of the battery pack can be effectively inhibited, and meanwhile, the liquid cooling plate can cool high-temperature gas in the exhaust channel, so that the thermal runaway can be further inhibited.
