[0029] The embodiment of the present application provides a heat exchange device, please refer to Figures 1 to 3 The heat exchange device includes a shell 1 and a freezer cooler 2. A accommodating cavity is formed inside the shell 1. The accommodating cavity includes an air inlet chamber, an equipment chamber and an air outlet chamber in sequence along the first horizontal direction. The air inlet chamber is provided with an air inlet 110, and the air inlet 110 is arranged on the top surface of the shell 1 part that encloses the air inlet chamber. The air outlet chamber is provided with an air outlet 120, and the air outlet 120 is arranged on the side of the shell 1 part that encloses the air inlet chamber. The freezer cooler 2 is arranged in the equipment chamber.

[0030] In an embodiment of the present application, the heat exchange device includes a shell 1 and a freezer cooler 2. The accommodating cavity of the shell 1 includes an air inlet chamber, an equipment chamber and an air outlet chamber in sequence along the first horizontal direction. The air inlet 110 is arranged on the top surface of the shell 1 part that encloses the air inlet chamber, the air outlet 120 is arranged on the side of the shell 1 part that encloses the air outlet chamber, and the freezer cooler 2 is arranged in the equipment chamber; compared with the heat exchange device of the prior art with front air flow and rear air outlet, the heat exchange device of the present application adopts the form of upper air inlet and side air outlet, which is more flexible to use and has smaller requirements on the horizontal spacing of the installation space, thereby reducing the installation requirements of the heat exchange device of the present application, so that the heat exchange device can be compactly arranged with other components.

[0031] In one embodiment, see Figure 2 The air outlet 120 is arranged on the side of the shell 1 along the second horizontal direction that encloses the air outlet chamber, and the first horizontal direction is perpendicular to the second horizontal direction.

[0032] It can be understood that, since the air inlet chamber, the equipment chamber and the air outlet chamber are distributed along the first horizontal direction, the length of the housing 1 along the first horizontal direction is generally greater than the length along the second horizontal direction.

[0033] In this way, the air outlet 120 is arranged on the side of the shell 1 along the second horizontal direction, and the pipe connected to the air outlet 120 is also correspondingly located on the side of the shell 1 along the second horizontal direction, avoiding the addition of additional pipes in the longer direction of the shell 1, and further reducing the spacing requirements in the horizontal direction of the installation space.

[0034] In other embodiments, the water inlet 210 and the water outlet 220 of the freezer 2 are both arranged on the side of the shell 1 that encloses the equipment chamber along the second horizontal direction, and other pipes or equipment that need to extend out of the shell 1 also protrude from the side of the shell 1 along the second horizontal direction, and are all arranged on the side opposite to the air outlet 120.

[0035] In one embodiment, see Figure 2 The heat exchange device also includes a primary filter 3, which is arranged on a side of the freezer 2 close to the air inlet chamber. The primary filter 3 is used to intercept particulate matter carried in the fresh air.

[0036] In one embodiment, see Figure 1 The heat exchanger also includes a differential pressure transmitter 4, which is used to monitor the pressure difference across the primary filter 3 to prevent filter failure. Specifically, when the differential pressure transmitter 4 detects a pressure drop exceeding 200 Pa across the primary filter 3, the system triggers an alarm to prompt the operator to replace the primary filter 3.

[0037] In one embodiment, see Figure 2 The heat exchange equipment also includes a wire mesh demister 5, which is arranged on a side of the freezer 2 close to the air outlet chamber. The wire mesh demister 5 is used to intercept water droplets splashing in the exhaust gas to control the gas humidity.

[0038] In one embodiment, see Figure 3 The heat exchanger also includes a temperature transmitter 6 for monitoring the gas temperature. This transmitter 6 is located within the air outlet chamber. When a lower temperature is desired, the valve opening of the water inlet 210 of the refrigerated surface cooler 2 is increased; when a higher temperature is desired, the valve opening of the water inlet 210 of the refrigerated surface cooler 2 is decreased to regulate the gas temperature.

[0039] Furthermore, the temperature data of the temperature transmitter 6 is sent to the control processing center in real time to facilitate data tracing.

[0040] In one embodiment, see Figure 1 An inspection door 130 is provided on the side of the shell 1 along the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular. The inspection door 130 is convenient for staff to repair or replace parts inside the shell 1.

[0041] For example, when the differential pressure transmitter 4 detects that the primary filter 3 needs to be replaced, the equipment maintenance personnel can open the inspection door 130 after shutting down the equipment to conveniently replace the primary filter 3 .

[0042] In one embodiment, see Figure 1There are two inspection doors 130, which are respectively arranged on the shell 1 part corresponding to the equipment chamber and the shell 1 part corresponding to the air inlet chamber. The inspection door 130 of the shell 1 part corresponding to the equipment chamber is convenient for the maintenance or replacement of the freezer 2 and the wire mesh defogger 5, and the inspection door 130 of the shell 1 part corresponding to the air inlet chamber is convenient for the maintenance or replacement of the primary filter 3.

[0043] In one embodiment, please refer to Figure 1 and Figure 3 The bottom of the side of the shell 1 is provided with a plurality of drain ports 7. Liquid may remain in the shell 1 due to the refrigeration cooler 2 and the wire mesh demister 5. The drain ports 7 can discharge the residual liquid in the shell 1 in a timely manner.

[0044] In one embodiment, please refer to Figure 1 and Figure 2 A support frame 8 is provided at the bottom of the shell 1 to prevent the shell 1 from directly contacting the ground, thereby better protecting the shell 1 and preventing moisture.

[0045] For other embodiments, please refer to Figures 1 to 3 The top surface of the shell 1 is provided with four hanging ears 140 , which are symmetrically distributed on the top surface of the shell 1 to facilitate the hanging and fixing of the heat exchange equipment.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
