Elastic heat dissipating bracket for deep-sea seal cavity

Abstract

The invention discloses an elastic heat dissipating bracket for a deep-sea seal cavity, comprising two end covers of supporting frame fixing plates, four the supporting frame fixing plates, four bottom plates of spring seats, four heat dissipating boards, four supporting frames of the heat dissipating boards, the spring seats and springs. Compared with the mode of traditional heat dissipation depending on the end covers, the effective utilization space of the end covers is released, heat dissipating area is enlarged, and heat conduction path is shortened; and compared with filling heat dissipating oil, the influence of oil liquid on electrical components and increased pressure of oil liquid caused by hot expansion are avoided. The specific elastic characteristics of the elastic heat dissipating bracket solves the problem of poor contact of a heat conductive surface owing to permanent deformation of the bracket in the cavity resulted from micro-deformation of the cavity caused by hydraulic pressure. The elastic heat dissipating bracket can enlarge the scope of application of underwater power equipment, and promote scientific and technological development such as exploration and development of underwater and even deep-sea resources, ocean observation and research, underwater operation and the like.

Description

technical field [0001] The invention relates to the technical field of high-power equipment application in underwater or deep sea environments, in particular to an elastic cooling frame applied in cylindrical sealed cavities underwater or deep sea. Background technique [0002] At present, the electrical parts of most high-power equipment in the ocean, especially the deep-sea environment, are sealed in a cylindrical pressure-resistant sealed cavity. Closely attached to the end cover for heat dissipation, or by pouring insulating heat dissipation oil to dissipate heat for electrical power devices. The way of dissipating heat through the end cover will inevitably occupy most of the available space of the end cover, and the heat conduction path is also very long. There are also disadvantages in the way of dissipating heat through oil filling. The temperature rise will inevitably cause the oil to expand, and pressure balance is required. Compensation is used to limit the pressu...

Problems solved by technology

The way of dissipating heat through the end cover will inevitably occupy most of the available space of the end cover, and the heat conduction path is also very long. There are also shortcomings in the way of dissipating heat through oil filling. The temperature rise will inevitably cause the oil to expand, and pressure balance is required. Compensation to limit the pressure increase caused by the expansion of the oil, and the oil is easy to have a strong effect on the electrical components, affecting its reliability
