Embodiment Construction

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0020] like Figure 1-2 As shown, the uniform disturbance device of the dry evaporator includes: a fixed rod 2 and an impeller; the impeller has a plurality of obliquely arranged blades 1 ; the impeller is pivotably arranged on the first end 4 of the fixed rod 2 . Through the above structure, during operation, since the blades on the impeller are arranged obliquely, there is a deflection angle between the blades and the flow direction of the refrigerant. When the refrigerant flows in from the refrigerant inlet pipe, the refrigerant has a certain impact on the blades. Force, and due to the existence of the deflection angle, the impeller starts to rotate, and the rotation of the impeller disturbs the refrigerant, thus destroying the characteristics of...

Abstract

The invention provides a dry-type evaporator and an equipartition disturbance device. The equipartition disturbance device of the dry-type evaporator comprises a fixed rod and an impeller. The impeller is provided with multiple inclined blades, and the blades are pivotally arranged at a first end of the fixed rod. By the aid of the dry-type evaporator and the equipartition disturbance device thereof, refrigerant is more uniformly distributed into each heat exchanging pipe by the disturbance of the blades, and the problem of low heat exchanging efficiency caused by uneven refrigerant distribution is solved. Original dry-type evaporator structure and process are not needed to be changed, and the dry-type evaporator and the equipartition disturbance device thereof are compact in structure and can be widely applicable to single-flow and multiple-flow heat exchangers.

Description

technical field [0001] The invention relates to the field of air conditioning, and more specifically, to a dry evaporator and an equalizing and disturbing device thereof. Background technique [0002] The dry evaporator in the prior art is equipped with a liquid equalizing plate with uniform openings, but due to the characteristics of the pipeline, although the refrigerant (that is, the refrigerant) enters each evaporation tube after passing through the liquid equalizing plate, it will still Causes the problem of the uneven amount of refrigerant entering each evaporator tube. On the one hand, this will cause the amount of refrigerant in a part of the heat exchange tubes to be too large to be completely evaporated, resulting in incomplete heat exchange; on the other hand, the amount of refrigerant in another part of the heat exchange tubes will be too small, resulting in "dry burning" phenomenon. The unevenness of the amount of refrigerant also causes the temperature of the...
