Abstract

A heat dissipating blower for cooling a condenser in a refrigerator with reduced vibration and reduced noise. The heat dissipating blower includes a drive device configured to generate a rotational force, a fan coupled to the drive device, a support member configured to support the drive device, and a support frame coupled to the support member. The support member includes a fastening portion coupled to the drive device, and a connection frame spaced apart from the support frame. The heat dissipating blower further includes one or more vibration-attenuation members disposed between the connection frame and the support frame.

First claim

What is claimed is:

1. A heat dissipating blower comprising:
a drive device having a rotating shaft and configured to generate a rotational force;
a fan coupled to the drive device;
a support member configured to support the drive device; and
a support frame coupled to the support member,
wherein the support member comprises:
a fastening portion coupled to the drive device; and
a connection frame disposed to surround a periphery of the fan, wherein an outer surface of the connection frame has a circular columnar shape, and a width between an inner surface of the connection frame and the outer surface of the connection frame is gradually decreasing from one side toward another side in an axial direction of the rotating shaft,
wherein the support frame comprises:
a passage portion for surrounding the connection frame, the passage portion being spaced apart from the outer surface of the connection frame by a gap; and
a protrusion portion disposed in the passage portion and protruded radially inward from the passage portion,
wherein the protrusion portion is disposed at the another side of the passage portion in the axial direction of the rotating shaft such that the protrusion portion covers the gap and a portion of the connection frame when viewed from the another side toward the one side in the axial direction of the rotating shaft,
wherein the connection frame further comprises a groove, and the support frame comprises recesses,
wherein the groove and the recesses are opened toward the same side, and
wherein the groove and the recesses are partially overlapped in a radial direction of the fan.

2. The heat dissipating blower of claim 1 further comprising a vibration-proof member disposed between the connection frame and the support frame.

3. The heat dissipating blower of claim 1 , wherein the support member further comprises bridges configured to interconnect the fastening portion and the connection frame.

4. The heat dissipating blower of claim 3 , wherein the bridges comprise first bridge portions extending toward the one side in the axial direction and second bridge portions coupled to the first bridge portions and configured to extend in a direction deviated from the radial direction by a predetermined angle.

5. A refrigerator comprising:
an evaporator configured to cool air by absorbing heat from the air through a refrigerant;
a compressor configured to compress the refrigerant supplied from the evaporator;
a condenser configured to dissipate heat while liquefying at least a part of the refrigerant compressed by the compressor, and
a heat dissipating blower configured to cool the condenser,
wherein the heat dissipating blower comprises:
a drive device having a rotating shaft and configured to generate a rotational force;
a fan coupled to the drive device;
a support member configured to support the drive device; and
a support frame to which the support member is coupled, and
wherein the support member comprises:
a fastening portion coupled to the drive device; and
a connection frame disposed to surround a periphery of the fan, wherein an outer surface of the connection frame has a circular columnar shape, and a width between an inner surface of the connection frame and the outer surface of the connection frame is gradually decreasing from one side toward another side in an axial direction of the rotating shaft,
wherein the support frame comprises:
a passage portion for surrounding the connection frame, the passage portion being spaced apart from the outer surface of the connection frame by a gap; and
a protrusion portion disposed in the passage portion and protruded radially inward from the passage portion,
wherein the protrusion portion is disposed at the another side of the passage portion in the axial direction of the rotating shaft such that the protrusion portion covers the gap and a portion of the connection frame when viewed from the another side toward the one side in the axial direction of the rotating shaft,
wherein the connection frame further comprises a groove, and the support frame comprises recesses,
wherein the groove and the recesses are opened toward the same side, and
wherein the groove and the recesses are partially overlapped in a radial direction of the fan.

6. The refrigerator of claim 5 , wherein the heat dissipating blower further comprises a vibration-attenuation member disposed between the connection frame and the support frame.

7. The refrigerator of claim 5 , wherein the support member further comprises bridges configured to interconnect the fastening portion and the connection frame.

8. The refrigerator of claim 7 , wherein the bridges comprise first bridge portions extending toward the one side in the axial direction.

9. The refrigerator of claim 8 , wherein the support member further comprises second bridge portions coupled to the first bridge portions and configured to extend in a direction deviated from the radial direction by a predetermined angle.

10. The refrigerator of claim 6 , wherein the vibration-attenuation member comprises an elastic material.
