Single-way channel serially connected type end frame refrigeration device

Abstract

The invention discloses a single-way channel serially connected type end frame refrigeration device, belonging to the field of low temperature refrigeration. The single-way channel serially connected type end frame refrigeration device comprises a frame body, a drainage air outlet, a coolant liquid inlet, a coolant channel. The single-way channel serially connected type end frame refrigeration device can be designed into any shape according to needs; the frame body is a layered structure with 2-6 layers; all the layers are welded together and are drilled with holes at corresponding positions, so that all the layers can be connected in series; each layer in the frame body is carved with a coolant channel; the first layer of the coolant channel is positioned at the backside and has an opening pointing downwards while the rest layers of the coolant channels are positioned at the front side and have openings pointing upwards; when the first layer and the second layer are welded, a clamping sheet is arranged between the first layer and second layer to separate the coolant channels of the two layers; screw holes are arranged at the outer edge of the frame body; the drainage air outlet and the coolant liquid inlet are welded together with the frame body; and one end of the coolant channel is communicated with the coolant liquid inlet while the other end of the coolant channel is communicated with the drainage air outlet. The single-way channel serially connected type end frame refrigeration device can efficiently realize refrigeration of an optical window and has the advantages of low cooling temperature, good effect, use convenience, use practicability and the like.

Description

technical field [0001] The invention relates to a one-way channel series end frame refrigeration device, which belongs to the field of low-temperature refrigeration. Background technique [0002] When the aircraft flies in the atmosphere at high speed, due to the requirements of some specific functions, the effective cooling and cooling of its optical window must be satisfied. The current refrigeration technology methods mainly include film cooling and internal cooling of optical window glass. However, the above two refrigeration methods are technically difficult, costly, and seriously interfere with the normal operation of the aircraft optical window. Considering the technical difficulties and technical implementation costs, it is urgent to develop a refrigeration device with good cooling effect, convenient use, low cost, and capable of cooling the end frame comprehensively. Contents of the invention [0003] The purpose of the present invention is to provide a unidirect...
