Abstract

A heat exchanger mounting structure is provided with a bracket, a load supporting section, a fitting member, and a contact section. The bracket is provided to one of a first heat exchanger and a second heat exchanger. The load supporting section is provided to the other heat exchanger to which the bracket is not provided, and supports a load transmitted from the one of the first heat exchanger and the second heat exchanger. The fitting member is provided to the one of the first heat exchanger and the second heat exchanger, to which the bracket is provided, and is fitted over the load supporting section. The contact section is in contact with at least a part of the upper portion of the bracket.

First claim

The invention claimed is:

1. A heat exchanger mounting structure, in which a first heat exchanger having a first core part and a second heat exchanger having a second core part are mounted together while the first core part and the second core part are stacked with each other, heat being exchanged between an internal fluid and an external fluid in the first core part, heat being exchanged between an internal fluid and the external fluid in the second core part, comprising:
a bracket provided to one of the first heat exchanger and the second heat exchanger;
a pair of engaging projection parts provided to one of the bracket and the other heat exchanger to which the bracket is not provided;
a single engaging portion provided to the other of the bracket and the other heat exchanger to be combined with the pair of engaging projection parts;
a load supporting section provided to the other heat exchanger, to which the bracket is not provided, to support a load from the one of the first heat exchanger and the second heat exchanger, the load supporting section being provided adjacent but not between the pair of engaging projection parts;
a fitting member provided to the one of the first heat exchanger and the second heat exchanger, to which the bracket is provided, and fitted to an outer side of the load supporting section, an inner surface of the fitting member located above the load support section directly contacting a majority of an outer surface of the load supporting section, the outer surface of the load supporting section extending into the fitting member; and
a contact section provided to the other heat exchanger, to be in contact with at least a part of the bracket by pressing the bracket from an upper side, wherein
the fitting member is supported between the load supporting section and the contact section in a state where the fitting member is fitted to the outer side of the load supporting section.

2. The heat exchanger mounting structure according to claim 1 , wherein the contact section is placed to the fitting member at a position right above the load supporting section.

3. The heat exchanger mounting structure according to claim 1 , wherein the contact section has a contact surface in contact with an upper surface of the bracket, and the contact surface has a sloped part which is sloped upward as going toward a tip end of the contact surface.

4. The heat exchanger mounting structure according to claim 1 , wherein
the contact section has
a contact surface in contact with an upper surface of the bracket, and
a rib extending in a direction intersecting with the contact surface.

5. The heat exchanger mounting structure according to claim 1 , wherein the bracket has a pressed part which is pressed by the contact section from the upper side, the pressed part being projected from a side surface of the bracket at a position lower than an upper end of the bracket.

6. The heat exchanger mounting structure according to claim 1 , wherein the load supporting section has a square-pillar-shaped protrusion part.

7. The heat exchanger mounting structure according to claim 6 , wherein
the bracket has a fitting hole passing through the engaging portion,
the engaging projection part has two nail projections spaced from each other by a predetermined interval, and
the fitting hole has an inner periphery surface defining the engaging portion, and the inner periphery surface is engaged with the two nail projections of the engaging projection part.

8. The heat exchanger mounting structure according to claim 6 , wherein
the fitting member is a rectangular pipe component surrounding all side surfaces of the square-pillar-shaped protrusion part of the load supporting section,
the contact section is a flat-plate component with a predetermined interval from an upper surface of the load supporting section, and covers at least the upper surface of the load supporting section, and
the contact section has a pressing part pressing the bracket from the upper side in a state where the fitting member is supported between the load supporting section and the contact section.

9. The heat exchanger mounting structure according to claim 8 , wherein
the fitting member has a top fitting part fitted on an outer side of the upper surface of the load supporting section, a lower fitting part fitted on an outer side of a lower surface of the load supporting section, a left side fitting part fitted on an outer side of a left side surface of the load supporting section and a right side fitting part fitted on an outer side of a right side surface of the load supporting section, and
a lower surface of the top fitting part is in contact with the upper surface of the load supporting section, and an upper surface of the top fitting part is in contact with a lower surface of the contact section, such that the top fitting part is supported between the contact section and the load supporting section.

10. The heat exchanger mounting structure according to claim 1 , wherein
a clearance is defined between the fitting member and the contact section such that the fitting member is able to incline relative to the contact section in the state where the fitting member is supported between the load supporting section and the contact section.

11. The heat exchanger mounting structure according to claim 1 , wherein
the fitting member and the bracket are located directly adjacent to each other in a direction perpendicular to a direction in which the fitting member opposes the load supporting section and the contact section, and in which the engaging portion opposes the engaging projection part.

12. The heat exchanger mounting structure according to claim 1 , wherein
the engaging projection part and the load supporting section are located directly adjacent to each other, and the load supporting section and the contact section are located directly adjacent to each other.

13. The heat exchanger mounting structure according to claim 1 , wherein
the first heat exchanger has an upper portion and the second heat exchanger has an upper portion, and wherein the bracket, the engaging projection part, the engaging portion, the load supporting section, the fitting member and the contact section are located at the upper portion of the first heat exchanger and the upper portion of the second heat exchanger.
