The heat exchanger set is described in detail with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of a valve assembly 100 according to an exemplary embodiment of the present application. Referring to fig. 1, the valve assembly 100 includes a first flange 10, a second flange 20, a fixing member 40, and a regulating valve 30, wherein the regulating valve 30 is disposed between the first flange 10 and the second flange 20, and the first flange 10 and the second flange 20 are fixed by the fixing member 40; the first flange 10 has a first channel 101, wherein the first channel 101 has a different dimension at an end of the first channel 101 close to the regulating valve 30 than at an end of the first channel 101 facing away from the regulating valve 30.

The regulating valve 30 here may be a one-way valve, such as a butterfly valve. Alternatively, in the open state of the non-return valve, gas may be communicated from the side where the second flange 20 is located to the side where the first flange 10 is located.

The fixing member 40 may be a bolt, which facilitates field assembly, disassembly and maintenance of the device. Correspondingly, first flange 10 and second flange 20 correspond and are provided with the multiunit mounting hole (a plurality of mounting holes can evenly set up), set up a bolt in every group mounting hole, and a plurality of bolts distribute in the outside of governing valve. Of course, in other embodiments, other fasteners may be used to secure the first and second flanges.

Here the second flange 20 has a second channel. In some embodiments, the second channel may be a straight tubular channel having a circular cross-section.

In some embodiments, the dimension of the first channel 101 near the end of the regulating valve 30 is smaller than the dimension of the first channel 101 away from the end of the regulating valve 30, so that the regulating valve 30 can be selected to be a smaller regulating valve than the end connected with the first flange 10, and the condition of a large valve distribution pipe can be avoided, thereby facilitating the cost control of the regulating valve.

In some embodiments, the first passage 101 may have a gradually increasing size in a direction along the first passage 101 toward an end of the regulating valve 30 toward an end of the first passage 101 away from the regulating valve 30. The regulator valve 30 is configured in such a manner as to facilitate gas flow.

For example, as shown in fig. 1, the first channel 101 comprises a first channel section 1012 on the side close to the control valve 30 and a second channel section 1011 on the side of the first channel section 1012 facing away from the control valve 30. The first channel section 1012 is connected to the second channel section 1011 at one end thereof near the regulating valve 30. The first channel section 1012 is of constant size and the second channel section 1011 is of increasing size in a direction along the first channel 101 towards the end of the regulating valve 30 which is closer to the regulating valve 30 than to the end of the first channel 101 which is farther from the regulating valve 30.

Specifically, the inclination degree of the inclined surface, the size of the end of the second passage section 1011, and the like can be adjusted to match the pipes, the connection ports, and the like to be connected.

Of course, in other embodiments, the size of the first passage may also gradually increase in the direction from the end of the first passage close to the regulating valve to the end of the first passage away from the regulating valve, which is not limited in this application.

It should be noted that, the size and the specific shape of the first channel may be set according to specific situations, and the present application is not limited thereto.

In some embodiments, the end surface of the first flange 10 connected to the regulating valve 30 is a flat end surface, and the end surface of the regulating valve 30 connected to the first flange 10 is also a flat end surface. A first seal 50 is provided between the first flange 10 and the regulating valve 30. Compared with the mode of adopting the sealing ring, the mode of adopting the sealing gasket avoids the arrangement of the sealing ring accommodating groove while ensuring the sealing performance of the joint of the first flange 10 and the regulating valve 30, simplifies the structure and is convenient to assemble.

In some embodiments, the end surface of the second flange 20 to which the regulating valve 30 is connected is a flat end surface, and the end surface of the regulating valve 30 to which the second flange 20 is connected is a flat end surface. A second gasket 60 is provided between the second flange 20 and the regulating valve 30. Compared with the mode of adopting the sealing ring, the mode of adopting the sealing gasket avoids arranging the sealing ring accommodating groove while ensuring the sealing performance of the joint of the second flange 20 and the regulating valve 30, simplifies the structure and is convenient to assemble.

The present application further provides a heat exchanger block, and fig. 2 is a partial sectional view of a heat exchanger block having a valve assembly according to an exemplary embodiment of the present application. The heat exchanger unit comprises the valve assembly 100, the compressor and the heat exchanger. The outlet of the compressor is provided with an exhaust connecting pipe 201, and the shell of the heat exchanger is provided with an air inlet connecting end 301. The exhaust connecting pipe 201 is fixedly connected with the second flange 20, and the intake connecting end 301 is fixedly connected with the first flange 10. Here, the valve assembly can be used for connection between the exhaust connection pipe 201 and the intake connection end 301 which are different in size.

The heat exchanger here may be a condenser.

The exhaust connection pipe 201 may be fixed to the second flange 20 by welding. For example, in the case where the second passage is a straight cylindrical passage having a circular cross section, the end of the exhaust connection pipe 201 may be inserted into the second passage and welded at the connection between the second flange 20 and the exhaust connection pipe 201.

The air inlet connection end 301 and the first flange 10 may be fixedly connected by a fixing member 303. The fixing member 303 may also be a bolt to facilitate disassembly and assembly and maintenance of the apparatus. Of course, the fixing piece can also be other fixing structures for fixing the air inlet connecting end and the first flange, and the fixing piece is not limited in the application and can be arranged according to specific conditions.

In some embodiments, the end surface of the first flange 10 connected to the intake connecting end 301 is a flat end surface, the end surface of the intake connecting end 301 connected to the first flange 10 is a flat end surface, and a third gasket 302 is disposed between the intake connecting end 301 and the first flange 10.

The first end 401 of the reducing connecting pipe 400 is fixedly connected with the second flange 20.

Here, the reducing connecting pipe 400 can also be fixed by welding. Accordingly, the first end 401 of the reducer connecting pipe 400 may be inserted into the second channel of the second flange 20 and welded at the junction of the two.

In some embodiments, the diameter of the tube at first end 401 of reducer connecting tube 400 is greater than the diameter of the tube at second end 402. For embodiments in which the size of the first passage 101 of the valve assembly near the end of the regulator valve 30 is smaller than the size of the first passage 101 at the end away from the regulator valve 30, the valve tube connection assembly 100' is capable of multiple dimensional changes, facilitating the adaptation of connections to tubing, connection ports of more diverse dimensions. Of course, the specific size and size relationship of the two ends of the reducing connecting pipe 400 can be set according to the requirement.
