Abstract

A control device accommodating unit (15) is provided in a section (50) accommodating an indoor air blower (7) adjacently to an indoor air flow-in port (16), and an impeller (7c) of the indoor air blower (7) is sequentially opposite to the indoor air flow-in port (16) and the control device accommodating unit (15) by rotation of the impeller (7c), and a space (51) is formed between the indoor air flow-in port (16) and the control device accommodating unit (15). In this configuration, it is possible to obtain a cooling device decreased in drop of air flow rate and drop of cooling performance due to mounting a control device (14).

Claims

1. A cooling device comprising:

a box body provided in a heating element storing box, the heating element storing box for storing a heating element in its inside, wherein at least one side of the box body is formed by a detachable panel,

an indoor air channel for sucking in and circulating air in the heating element storing box, an outdoor air channel for sucking in and circulating outdoor air,

an indoor air blower for conveying air into the indoor air channel,

an outdoor air blower for conveying air into the outdoor air channel,

a heat exchanger having an indoor air flow-in port, and exchanging sensible heat between the air in the indoor air channel and the air in the outdoor air channel,

a control device for controlling the indoor air blower and the outdoor air blower, and

a control device accommodating unit accommodates the control device

wherein the heat exchanger is disposed at the downstream side of the indoor air blower and the outdoor air blower,

the indoor air flow-in port and the control device accommodating unit are disposed adjacent to a section that accommodates the indoor air blower, and impellers of the indoor air blower are sequentially opposite to the indoor air flow-in port and the control device accommodating unit, by rotation of the impellers, and

a space is further formed between the indoor air flow-in port and the control device accommodating unit

the control device accommodating unit has a flow-in port of the control device accommodating unit and a flow-out port of the control device accommodating unit for cooling and ventilating in the control device accommodating unit,

the flow-in port of the control device accommodating unit communicates with the high pressure section of air blown by the indoor air blower, and

the flow-out port of the control device accommodating unit communicates with an indoor air leading part for leading the air in the heating element accommodating unit into the indoor air intake port.

2. The cooling device of claim 1, wherein the flow-in port of the control device accommodating unit is disposed in a high temperature area in the control device accommodating unit.

3. The cooling device of claim 1, wherein the flow-out port of the control device accommodating unit is disposed in a high temperature area in the control device accommodating unit.

4. The cooling device of claim 1, wherein a high temperature area in the control device accommodating unit, the flow-in port of the control device accommodating unit, and the flow-out port of the control device accommodating unit are substantially disposed on a straight line.

5. The cooling device of claim 1, further comprising:

a drain hole provided at a corner of a section of the box body for accommodating the outdoor air blower, and communicating with the outside.

6. The cooling device of claim 1, wherein the box body includes a top face, a bottom face and lateral faces, the cooling device further comprising:

a fixing member provided at the top face, the bottom face and both of the lateral faces of the box body, and having an opening part,

a tightening member penetrating through the opening part for tightening the fixing member and the heating element storing box, and

a sealing member formed between the fixing member and the heating element storing box,

wherein the fixing member includes;

a first fixing member provided in the top face, and having a first opening part of hole shape, and

a second fixing member provided in the bottom face and both lateral faces, and having a second opening part of notch shape.

7. The cooling device of claim 1, wherein the box body is:

formed of a plate member at a side different from the one side of the box body formed by the detachable panel, and

at least a double sealing process is applied on a ridge portion formed between a side adjacent to the plate member and the plate member, wherein the side adjacent is different from the panel, and the plate member.

8. The cooling device of claim 1, further comprising:

a sealing and insulating part provided on the top face of the box body.

9. The cooling device of claim 8, wherein the sealing and insulating part is made of a polyethylene sheet.
