Title:
REFRIGERANT DISTRIBUTION DEVICE, HEAT EXCHANGER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/221500
Kind Code:
A1
Abstract:
The present application relates to the technical field of air conditioning. Disclosed is a refrigerant distribution device, comprising a pipe body, a movable component and a driving component. The pipe body is provided with a refrigerant inlet/outlet; the interior of the pipe body is provided with a refrigerant distribution space; a side wall of the pipe body is provided with 2n+1 branch pipe orifices in the lengthwise direction of the pipe body, n being a natural number greater than or equal to 1; and the branch pipe orifices are used for connecting heat exchange branches. The movable component is slidably arranged in the refrigerant distribution space, and comprises n U-shaped pipes; when the movable component is located at a first position, two pipe orifices of the n-th U-shaped pipe are connected to the 2n-th and 2n+1-th branch pipe orifices of the pipe body; and when the movable component is located at a second position, the pipe orifices of each U-shaped pipe avoid the respective branch pipe orifices, such that the 2n+1-th branch pipe orifices are connected in parallel. The driving component is arranged inside the pipe body and is used for driving the movable component to slide between the first position and the second position. Further disclosed in the present application are a heat exchanger and an air conditioner.
