[0002] Brazing, as an important joining process, plays a crucial role in many industrial fields such as aerospace, automobile manufacturing, electronics, and refrigeration equipment.
[0003] In traditional designs, the Chiller heat exchanger, LCC heat exchanger, and valve plate are all independent parts that need to be brazed and assembled separately. The Chiller and LCC also require mounting plates, fastening bolts, connectors, and sealing rings to function properly. This design involves numerous parts and cumbersome assembly steps, resulting in high costs, large space requirements, and a high risk of leakage due to the sealing ring structure. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an integrated brazing assembly that saves resources, eliminates parts such as mounting plates, fastening bolts, joints and sealing rings, makes the overall structure more compact, occupies less space, has a high sealing safety factor, and reduces production costs.
[0005] This utility model discloses an integrated brazing assembly, comprising an LCC heat exchanger and a Chiller heat exchanger, with the Chiller heat exchanger positioned to the side of the LCC heat exchanger; it also includes a composite plate and a valve plate, with the bottom ends of both the LCC and Chiller heat exchangers connected to the top end of the composite plate, and the top end of the valve plate connected to the bottom end of the composite plate; the LCC and Chiller heat exchangers are arranged on the reverse side of the valve plate, and the three components are integrated into a single brazing assembly via the composite plate, simultaneously enabling communication between the LCC, Chiller, and valve plates, thereby saving resources, eliminating the need for mounting plates, fastening bolts, joints, and sealing rings for the LCC and Chiller heat exchangers, resulting in a more compact overall structure, smaller footprint, higher sealing safety factor, and reduced production costs.
[0006] Preferably, the device further includes a first reserved port, a second reserved port, a third reserved port, and a fourth reserved port. The first reserved port, the second reserved port, the third reserved port, and the fourth reserved port are respectively disposed on the composite plate. The inlet and outlet between the LCC heat exchanger and the valve plate are connected through the first reserved port and the second reserved port. The inlet and outlet between the Chiller heat exchanger and the valve plate are connected through the third reserved port and the fourth reserved port. The refrigerant enters the LCC heat exchanger through the flow channel of the valve plate and passes through the first reserved port. After entering the LCC heat exchanger, the refrigerant flows through a specific channel of the LCC heat exchanger and collects at the outlet. Then, the refrigerant re-enters the valve plate through the second reserved port. The refrigerant enters the Chiller heat exchanger through the flow channel of the valve plate and passes through the fourth reserved port. After entering the Chiller heat exchanger, the refrigerant flows through a specific channel of the Chiller heat exchanger and collects at the outlet. Then, the refrigerant re-enters the valve plate through the third reserved port, thereby realizing the circulation and transportation of refrigerant between the LCC heat exchanger, the Chiller heat exchanger, and the valve plate.
[0007] Preferably, the composite plate and the valve plate are connected by brazing; this achieves a seal between the flow channel of the valve plate and the first reserved port, the second reserved port, the third reserved port and the fourth reserved port, while also fixing the composite plate and the valve plate together.
[0008] Preferably, the LCC heat exchanger and the Chiller heat exchanger are connected to the composite plate by brazing; this achieves sealing between the inlet and outlet of the LCC heat exchanger and the first reserved port, the second reserved port, the third reserved port and the fourth reserved port, while fixing the LCC heat exchanger and the Chiller heat exchanger to the top of the composite plate.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the LCC heat exchanger and the Chiller heat exchanger are arranged on the opposite side of the valve plate, and the three are processed into an integral brazed assembly in one step through a composite plate. At the same time, the LCC heat exchanger, the Chiller heat exchanger and the valve plate are connected, thereby saving resources, eliminating the need for mounting plates, fastening bolts, joints and sealing rings of the LCC heat exchanger and the Chiller heat exchanger, making the overall structure more compact, occupying less space, having a high sealing safety factor, and reducing production costs.

[0019] like Figure 3 As shown, it also includes a first reserved port 5, a second reserved port 6, a third reserved port 7 and a fourth reserved port 8. The first reserved port 5, the second reserved port 6, the third reserved port 7 and the fourth reserved port 8 are respectively set on the composite plate 3. The inlet and outlet between the LCC heat exchanger 1 and the valve plate 4 are connected through the first reserved port 5 and the second reserved port 6. The inlet and outlet between the Chiller heat exchanger 2 and the valve plate 4 are connected through the third reserved port 7 and the fourth reserved port 8.
[0020] In this embodiment, the LCC heat exchanger 1 and the Chiller heat exchanger 2 are arranged on the opposite side of the valve plate 4, and the three are processed into an integral brazed assembly in one step through the composite plate 3. At the same time, the LCC heat exchanger 1, the Chiller heat exchanger 2 and the valve plate 4 are connected, thereby saving resources and eliminating the need for mounting plates, fastening bolts, joints and sealing rings of the LCC heat exchanger 1 and the Chiller heat exchanger 2. This makes the overall structure more compact, occupies less space, has a high sealing safety factor, and reduces production costs.

[0023] like Figure 2 As shown, the LCC heat exchanger 1 and the Chiller heat exchanger 2 are connected to the composite plate 3 by brazing.
[0024] In this embodiment, the refrigerant enters the LCC heat exchanger 1 through the flow channel of the valve plate 4, passes through the first reserved port 5, and then flows through a specific channel of the LCC heat exchanger 1 before converging at the outlet. The refrigerant then re-enters the valve plate 4 through the second reserved port 6, and through the flow channel of the valve plate 4, passes through the fourth reserved port 8 before entering the Chiller heat exchanger 2. After entering the Chiller heat exchanger 2, the refrigerant flows through a specific channel of the Chiller heat exchanger 2 before converging at the outlet. Finally, the refrigerant re-enters the valve plate 4 through the third reserved port 7, thus achieving a circulating transport of the refrigerant between the LCC heat exchanger 1, the Chiller heat exchanger 2, and the valve plate 4. This also ensures a seal between the flow channel of the valve plate 4 and the first reserved port 5, the second reserved port 6, the third reserved port 7, and the fourth reserved port 8, while simultaneously fixing the composite plate 3 to the valve plate 4.
[0025] The present invention discloses an integrated brazing assembly in which, during operation, the LCC heat exchanger 1 and the Chiller heat exchanger 2 are arranged on the reverse side of the valve plate 4, and the three are processed into an integrated brazing assembly in one step through the composite plate 3, thereby connecting the LCC heat exchanger 1, the Chiller heat exchanger 2 and the valve plate 4.
