Micro-channel condenser even in refrigerant distribution and refrigerator

Abstract

The invention discloses a micro-channel condenser even in refrigerant distribution and a refrigerator. The micro-channel condenser comprises a first liquid collecting tube and a second liquid collecting tube, at least one refrigerant distribution device and partitioning plates are arranged inside the first liquid collecting tube, the number of the partitioning plates is the same as that of the refrigerant distribution devices, the refrigerant distribution devices and the partitioning plates inside a cavity of the first liquid collecting tube are sequentially and alternatively arranged along the axis of the first liquid collecting tube, and at least one refrigerant distribution device and partitioning plates are also arranged inside the second liquid collecting tube, wherein the partitioning plates are one fewer than the refrigerant distribution devices. The refrigerant distribution devices and the partitioning plates inside a cavity of the second liquid collecting tube are sequentially and alternatively arranged along the axis of the second liquid collecting tube. The refrigerant distribution devices are arranged inside the first liquid collecting tube and the second liquid collecting tube, in this way, refrigerant can be evenly distributed inside the micro-channel condenser, and meanwhile due to the facts that the refrigerant distribution devices are simple in structure and are arranged inside the cavity of the first liquid collecting tube and the cavity of the second liquid collecting tube, compared with an existing condenser of an external distributor, the size is smaller, and the structure is simpler.

Description

technical field [0001] The invention relates to the technical field of micro-channel condensers, in particular to a micro-channel condenser and a refrigerator with uniform refrigerant distribution. Background technique [0002] In a prior art, the inner cavity of the liquid collecting pipe of the condenser is connected up and down as a whole. When the refrigerant flows slowly in the liquid collecting pipe, it is easily affected by factors such as gravity, resulting in low pressure of the refrigerant in the liquid collecting pipe. It is often shown that the pressure of the refrigerant in the lower part of the liquid collection pipe is greater than that in the upper part of the liquid collection pipe, so the flow rate of the refrigerant in the lower part of the liquid collection pipe in the microchannel of the flat tube is greater than that in the upper part of the liquid collection pipe, and it is difficult to achieve refrigeration. The agent is evenly distributed in the micr...

[0002] In a prior art, the inner cavity of the liquid collecting pipe of the condenser is connected up and down as a whole. When the refrigerant flows slowly in the liquid collecting pipe, it is easily affected by factors such as gravity, resulting in low pressure of the refrigerant in the liquid collecting pipe. It is often shown that the pressure of the refrigerant in the lower part of the liquid collection pipe is greater than that in the upper part of the liquid collection pipe, so the flow rate of the refrigerant in the lower part of the liquid collection pipe in the microchannel of the flat tube is greater than that in the upper part of the liquid collection pipe, and it is difficult to achieve refrigeration. Agent is evenly distributed in the microchannel condenser

[0003] In another prior art, partitions are used to divide the inner cavity of the liquid collection pipe into several subspaces, and then the distributor outside the liquid collection pipe is used to distribute the refrigerant, and then the refrigerant is distributed by several branch pipes outside the liquid collection pipe. Introduce them into separate subspaces respectively. Although the above method can realize the uniform distribution of refrigerant, the external distributor and branch pipe will make the structure of the condenser very complicated, and the volume of the condenser will be larger, increasing the The installation of the condenser is difficult, and at the same time, the redundant external structure also increases the probability of condenser failure
