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.

Claims

1. A heat dissipating blower comprising:

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, wherein the support member comprises;

a fastening portion coupled to the drive device; and

a connection frame spaced apart from the support frame.

2. The heat dissipating blower of claim 1, wherein the connection frame comprises an inner tapering surface formed in a convex shape toward an inner side.

3. The heat dissipating blower of claim 2, wherein the connection frame further comprises a groove open toward one side in an axial direction.

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

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

6. The heat dissipating blower of claim 5, wherein the bridges comprise first bridge portions extending toward one side in an axial direction and second bridge portions coupled to the first bridge portions and configured to extend in a direction deviated from a radial direction by a predetermined angle.

7. A heat dissipating blower comprising:

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,

wherein the support member comprises;

a fastening portion coupled to the drive device; and

a connection frame coupled to the support member, the connection frame comprising an inner tapering surface formed in a convex shape toward an inner side.

8. The heat dissipating blower of claim 7, wherein the connection frame is disposed in a spaced-apart relationship with the support frame.

9. 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 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 in a spaced-apart relationship with the support frame.

10. The refrigerator of claim 9, wherein the connection frame comprises an inner tapering surface formed in a convex shape toward an inner side.

11. The refrigerator of claim 9, wherein the connection frame comprises a groove open toward one side in an axial direction.

12. The refrigerator of claim 9, wherein the heat dissipating blower further comprises a vibration-attenuation member disposed between the connection frame and the support frame.

13. The refrigerator of claim 9, wherein the support member further comprises bridges configured to interconnect the fastening portion and the connection frame.

14. The refrigerator of claim 13, wherein the bridges comprise first bridge portions extending toward one side in an axial direction.

15. The refrigerator of claim 14, wherein the support member further comprises second bridge portions coupled to the first bridge portions and configured to extend in a direction deviated from a radial direction by a predetermined angle.

16. The refrigerator of claim 12, wherein the vibration-attenuation member comprises an elastic material.
