Abstract
A heat exchanger for a refrigerated merchandiser includes a fan housing having an asymmetrical configuration. The fan housing can include a first section with a first open outlet and a second section with a second open outlet. A first fan is positioned in the first section and configured to create a first airflow through the first open outlet. A second fan is positioned in the second section and configured to create a second airflow through the second open outlet. An evaporator is in fluid communication with the first open outlet and second open outlet. The first section is asymmetrical about a first section central axis and the second section is asymmetrical about a second section central axis.

A heat exchanger for a refrigerated merchandiser comprising:
- a fan housing including a first section with a first open outlet and a second section with a second open outlet, each of the first section and the second section having a first side wall and a second side wall;
- a first fan positioned in the first section and configured to create a first airflow through the first open outlet;
- a second fan positioned in the second section and configured to create a second airflow through the second open outlet;
- and
- an evaporator in fluid communication with the first open outlet and second open outlet,
- wherein a first section central axis extends through a center of the first section and a second section central axis extends through a center the second section, and
- wherein the first side wall and the second side wall of the first section are oriented at different angles relative to the first section central axis such that the first section is asymmetrical about the first section central axis, and the first side wall and the second side wall of the second section are oriented at different angles relative to the second section central axis such that the second section is asymmetrical about the second section central axis.
A heat exchanger for a refrigerated merchandiser comprising:
- a fan housing including a first side wall, a second side wall, and an outlet;
- a first fan positioned in the fan housing and configured to create a first airflow through the outlet;
- a second fan positioned in the fan housing and configured to create a second airflow through the outlet;
- and
- an evaporator in fluid communication with the outlet,
- wherein a housing central axis extends through a center of the fan housing, and
- wherein the first side wall and the second side wall are oriented at different angles relative to the housing central axis such that the fan housing is asymmetrical about the housing central axis.
A heat exchanger for a refrigerated merchandiser comprising:
- a fan housing first section having a first rear wall, a first side wall, a second side wall, and a first open outlet;
- a fan housing second section having a second rear wall, a third side wall, a fourth side wall, and a second open outlet;
- a first fan positioned in the first section and configured to create a first airflow through the first open outlet;
- a second fan positioned in the second section and configured to create a second airflow through the second open outlet;
- and
- an evaporator in fluid communication with the first open outlet and second open outlet,
- wherein the first side wall intersects the first rear wall at a first angle, the second side wall intersects the first rear wall at a second angle that is different than the first angle, the first side wall intersects the first open outlet at a third angle complementary to the first angle, and the second side wall intersects the first open outlet at a fourth angle complementary to the second angle.
