Embodiment Construction

[0024] The present invention will be described in further detail below.

[0025] like figure 1 , an aviation-based plate-fin heat exchanger fin flow channel arrangement structure based on field synergy, which can make cold and hot fluid cross-flow for heat exchange. The structure includes a heat exchanger core 3, on which the cold side seals 1 are welded at both ends of the cold liquid flow passage, and the hot side seals 2 are welded at both ends of the hot liquid flow passage, or only the cold side seals can be welded. Cover 1 or Hot Edge Seal Cover 2. like figure 2 As shown, the arrangement of the flow channels of the fins in the heat exchanger core 3 forms a certain angle with the flow direction of the fluid. like image 3 , the angle between the flow channel of the fin and the incoming flow direction is equal to the angle θ between the fluid temperature gradient and the velocity vector under specific working conditions, cosθ=U·ΔT / (▏U▕·▏▏T▕), U is the velocity vector...

Abstract

The invention discloses a field-synergy-based fin channel arrangement structure of a plate-fin heat exchanger for aviation. Angle relationship Reasonably arrange the angle of the fin flow channel, thereby strengthening the heat transfer, breaking through the single design limitation of the traditional radiator core fin flow channel arrangement, according to the principle of field synergy, this design can improve the temperature field and velocity field of the heat exchange area. Synergy can effectively improve the heat transfer performance of the product. Therefore, under the same design conditions, the product is smaller in size and lighter in weight, which can save the pod space, reduce the weight of environmental control system equipment, and improve the power-to-weight ratio and tactical capabilities of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of aviation pod environmental control, and in particular relates to a fin flow channel arrangement structure of a plate-fin heat exchanger based on field coordination for aviation. Background technique [0002] Temperature control in aircraft electronics pods is critical, as temperatures that are too high or too low can cause the equipment to not work properly or even fail. The radiator, as an essential heat exchange equipment for the pod environmental control system, is particularly important in ensuring the ambient temperature. The size and weight of accessories in an aircraft pod greatly affect the tactical capability of the carrier aircraft. At present, the weight and volume requirements of aircraft accessories for accessories are increasing year by year. The structural design of the traditional plate-fin radiator has gradually failed to meet the requirements in terms of heat dissipation performance, v...
