Description

Embodiments of the present invention relate to a heat source device.

A heat source device including a heat exchanger and cycle components such as a compressor, an accumulator, and a receiver that form a part of a refrigeration cycle together with the heat exchanger is known. If the cycle components are not fixed to the frame or bottom plate of the heat source device, vibration can damage the piping connected to these cycle components.

The end plate 91A and the end plate 92A are connected by a connecting tool 93A that is long in the Z direction. In the present embodiment, the guide 50 and the first heat exchanger 6A are connected by using the connector 93A.

FIG. 8 is a diagram schematically showing an example of a connection structure between the guide 50 and the first heat exchanger 6A. This figure includes a cross section of the first heat exchanger 6A and connector 93A along line VIII-VIII in FIG. 7 and a guide 50.

As described above, the first heat exchanger 6A has a first row L1, a second row L2, and a third row L3, and fins 66 are arranged in each of the rows L1 to L3. The end plate 92A has a base 921 that covers the ends of the rows L1 to L3, and a pair of protruding portions 922 that protrude from both ends of the base 921.

The third portion 53 of the guide 50 has an end wall 56 formed by bending the end portion parallel to the Y direction. The connector 93A has an L-shaped cross section and is in contact with both the protruding portion 922 and the end wall 56.

The protruding portion 922 and the connecting tool 93A are connected by screws S2 at a plurality of positions in the Z direction. The end plate 91A also has a protruding portion like the end plate 92B, and the protruding portion and the connecting tool 93A are connected by screws S2 at a plurality of positions in the Z direction. The end wall 56 and the connecting tool 93A are connected by screws S3 at a plurality of positions in the Z direction.

A similar structure can be applied to the connection between the guide 50 and the second heat exchanger 6B. FIG. 9 is a diagram schematically showing an example of a connection structure between the guide 50 and the second heat exchanger 6B. The upper unit 62b of the second heat exchanger 6B has an end plate 92B similar to the end plate 92A of the first heat exchanger 6A. Although not shown in FIG. 9, the lower unit 61b of the second heat exchanger 6B also has a similar end plate, and the end plate and the end plate 92B are L by screws S2 at a plurality of positions in the Z direction. It is connected to the character-shaped connector 93B.

The fifth portion 55 of the guide 50 has an end wall 57 formed by bending the end portion parallel to the X direction. The end wall 57 and the connector 93B are connected by screws S3 at a plurality of positions in the Z direction.

Here, an example of the effect of the present embodiment will be described.
In the present embodiment, the receivers 7A to 7C have a long shape in the Z direction. Therefore, if the receivers 7A to 7C are only fixed to the bottom plate 14A, the upper part of the receivers 7A to 7C may vibrate significantly due to the operation of the compressors 4A and 4B and the external force. Such vibrations can contribute to damage to the pipes connected to the receivers 7A-7C.

In this regard, in the present embodiment, not only the lower end portions 71 of the receivers 7A to 7C but also the intermediate portion is supported by the guide 50. Therefore, the vibration of the receivers 7A to 7C can be suppressed, and as a result, the resistance to the vibration of the heat source device 1 can be improved.

Further, in the present embodiment, the heat exchangers 6A and 6B surround more than half of the periphery of the receivers 7A to 7C. Normally, in such a configuration, it is difficult to connect the guide 50 to the frame or the like of the heat source device 1. If the guide 50 is fixed to the inner surface (the surface where the fins 66 are lined up) of the heat exchangers 6A and 6B, a complicated structure is required to secure the strength. On the other hand, in the present embodiment, the guide 50 is connected to the end plates 92A and 92B of the heat exchangers 6A and 6B. In this case, the guide 50 can be fixed inside the heat source device 1 without using a complicated structure.

Further, in the present embodiment, the connector 93A that connects the lower unit 61a and the upper unit 62a of the first heat exchanger 6A and the connector 93B that connects the lower unit 61b and the upper unit 62b of the second heat exchanger 6B are connected. Is used to fix the guide 50. In this case, a bracket or the like for connecting the guide 50 to the end plates 92A and 92B becomes unnecessary, and the number of parts can be reduced.

Further, the guide 50 is arranged below the exhaust unit 22. With such a structure, the exhaust unit 22 and the guide 50 do not interfere with each other. Therefore, for example, the guide 50 is arranged so as to partially overlap the exhaust unit 22 in the Z direction, so that the layout of the guide 50 inside the heat source device 1 becomes easy.

Further, in the present embodiment, the three receivers 7A to 7C are arranged in a straight line. Further, the guide 50 includes a first portion 51 parallel to the direction in which the receivers 7A to 7C are arranged, and the first portion 51 is connected to an intermediate portion of the receivers 7A to 7C. With such a configuration, the receivers 7A to 7C can be easily fixed without bending the guide 50 in a complicated manner or providing individual guides for each of the receivers 7A to 7C.

In the present embodiment, the case where the heat source device 1 includes four heat exchangers 6A to 6D is illustrated, but the number of heat exchangers included in the heat source device 1 is not limited to this example. For example, the heat exchangers 6A and 6B may be one continuous heat exchanger. Further, the heat exchangers 6C and 6D may be one continuous heat exchanger. As yet another example, the heat exchangers 6A to 6C are one continuous heat exchanger, and the fourth heat exchanger 6D may be connected as a subcool coil on the downstream side in the refrigerant flow direction of the heat exchanger. ..

Further, in the present embodiment, the case where the heat exchangers 6A to 6D are divided into two in the vertical direction and divided into three rows L1 to L3 in the thickness direction is illustrated. However, the heat exchangers 6A to 6D do not have to be divided in the vertical direction and the thickness direction. In this case, the guide 50 and the end plates of the heat exchangers 6A and 6B may be directly connected or may be connected via a member such as a bracket.

Further, in the present embodiment, the case where the heat source device 1 includes three receivers 7A to 7C is illustrated, but the number of receivers 7A to 7C included in the heat source device 1 is not limited to this example. For example, the heat source device 1 may include one receiver connected to the downstream side of the heat exchangers 6A to 6C. In this case, the guide 50 supports the intermediate portion of the receiver only. Further, the heat source device 1 may include two or four or more receivers. When a plurality of receivers are arranged in this way, the guide 50 may support all receivers or some receivers. Further, a plurality of guides 50 supporting different receivers may be arranged.

Further, in the present embodiment, a structure in which the intermediate portion of the receivers 7A to 7C is supported by the guide 50 is illustrated. Similarly, the structure supporting the intermediate portion can be applied to other cycle components such as the accumulator 2, the compressors 4A and 4B, and the oil separator 5.
