Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, specifically a support frame for a plate heat exchanger. Background Technology

[0002] Currently, heat exchange devices are mainly divided into two types: shell and tube heat exchangers and plate heat exchangers. Under the same fluid resistance and pump power consumption, the heat transfer coefficient of plate heat exchangers is three to five times higher than that of shell and tube heat exchangers. Shell and tube heat exchangers mainly have disadvantages such as large footprint, complex manufacturing, difficulty in cleaning, large heat loss, small capacity, and easy scaling. Therefore, in the field of condensation heat exchange, there is a need for a high-efficiency heat exchanger that has a small footprint, is relatively simple to manufacture, and facilitates gas-liquid separation.

[0003] To solve the above problems, after searching, CN109631628A, a plate heat exchanger is disclosed. The paper includes a support frame and a heat exchange core that is inclined and fixed inside the support frame. The side of the heat exchange core is provided with an air inlet and an air outlet. The air inlet is installed at the upward inclined end of the heat exchange core, and the air outlet is installed at the downward inclined end of the heat exchange core. The upper opening of the support frame is larger than the lower opening, and the lower part of the support frame is bent inward.

[0004] While the aforementioned devices can enhance the heat exchange efficiency of the heat exchange core and improve condensation, in actual use, the plate heat exchanger itself is quite heavy. Coupled with the stress of the pipe connections, if the strength and rigidity of the support frame are insufficient, or if the support is uneven during installation, deformation can easily occur, affecting the normal use of the plate heat exchanger. Utility Model Content

[0005] The purpose of this utility model is to provide a support frame for a plate heat exchanger to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, a plate heat exchanger support frame is provided, including a heat exchanger body. A support frame body is fixedly installed at the bottom of the heat exchanger body. The support frame body consists of a front support frame and a rear support frame. A reinforcing plate is fixedly installed at the bottom of the front support frame and the rear support frame. A support plate A and a support plate B are respectively provided on the front support frame. Both support plate A and support plate B cover the end plate of the heat exchanger body. A support seat is fixedly provided at the bottom of both support plate A and support plate B.

[0007] Preferably, the front support frame and the rear support frame are symmetrical about the central axis of the heat exchanger body, and the front support frame and the rear support frame cover the front and rear sides of the heat exchanger body, respectively.

[0008] Preferably, the reinforcing plates are arranged in two sets at the bottom of the front support frame and the rear support frame, and the interior of both sets of reinforcing plates is provided with openings. The bottoms of the reinforcing plates, the front support frame and the rear support frame are horizontally arranged.

[0009] Preferably, the front support frame includes a support plate A, a support plate B, and a connecting piece. The support plate A and the support plate B are symmetrical about the connecting piece. One end of the connecting piece is welded and fixed to the support plate B, and the other end of the connecting piece is welded and fixed to the support plate A.

[0010] Preferably, the support plate A includes a first fixing bolt, a receiving port, a second fixing bolt, a force-bearing plate, a reinforcing rib, a support base, and a mounting port. The upper part of the support plate A is screwed to the heat exchanger body end plate by two sets of first fixing bolts, and the force-bearing plate at the bottom of the support plate A is screwed to the heat exchanger body end plate by second fixing bolts.

[0011] Preferably, the support plate A has a circular receiving opening in the middle, which is fitted onto the medium port at the end of the heat exchanger body; a support base is welded and fixed to the bottom of the force-bearing plate.

[0012] Preferably, the load-bearing plate and the support base are vertically distributed, and the support base has two sets of mounting openings evenly distributed, with the mounting openings being U-shaped; three sets of reinforcing ribs are evenly welded between the load-bearing plate and the support base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The support plate A and connecting piece on the front support frame of this utility model cover the end face of the heat exchanger body and are fixed by multiple sets of bolts. By increasing the force-bearing area between the front support frame and the heat exchanger body, the stability of the front support frame when supporting the heat exchanger body is improved, and the pressure on a single support frame is avoided, thereby improving the load-bearing capacity of the entire support system and enabling the plate heat exchanger to adapt to higher working pressure and larger throughput.

[0015] 2. This utility model uses a front support frame and a rear support frame, which are respectively screwed to the bottom sides of the heat exchanger body and connected as a whole by a reinforcing plate, to form a stable support structure for the heat exchanger body. This forms a stable mechanical system that can effectively distribute and bear the weight of the plate heat exchanger and various stresses generated during operation. It prevents the support frame from deforming, tilting, or displacing due to uneven stress, ensuring that the plate heat exchanger maintains a stable posture during operation and guaranteeing that the heat exchanger works stably for a long time.

[0028] Please see Figure 1-6 This utility model provides a plate heat exchanger support frame, including a heat exchanger body 1, and a support frame body 2 fixedly installed at the bottom of the heat exchanger body 1. The support frame body 2 is composed of a front support frame 21 and a rear support frame 22. A reinforcing plate 23 is fixedly installed at the bottom of the front support frame 21 and the rear support frame 22. A support plate A211 and a support plate B212 are respectively provided on the front support frame 21. Both support plates A211 and B212 cover the end plates of the heat exchanger body 1. A support seat 2115 is fixedly provided at the bottom of both support plates A211 and B212.

[0029] Working Principle: In actual use, the bottom of the heat exchanger body 1 is supported by the support frame body 2. The support frame body 2 consists of a front support frame 21 and a rear support frame 22. The front support frame 21 and the rear support frame 22 are screwed to the bottom sides of the heat exchanger body 1 respectively, and are connected into one piece by the reinforcing plate 23, forming a stable support structure for the heat exchanger body 1. This forms a stable mechanical system that can effectively distribute and bear the weight of the plate heat exchanger and various stresses generated during operation, preventing the support frame from deforming, tilting, or displacing due to uneven stress, and ensuring that the plate heat exchanger maintains a stable posture during operation. At the same time, the support plate A211 and connecting piece 213 on the front support frame 21 cover the end face of the heat exchanger body 1 and are fixed by multiple sets of bolts. By adding the front support frame 21, the heat exchanger body 1 can be further stabilized. The front support frame 21 increases the force-bearing area between itself and the heat exchanger body 1, thereby improving the stability of the front support frame 21 when supporting the heat exchanger body 1. The bottom of the front support frame 21 is screwed to the foundation bolts on the ground through the mounting port 2116. This enhances the vibration resistance of the front support frame 21, reduces the transmission and amplification of vibration, lowers the risk of component loosening, wear, or even damage caused by vibration, and extends the service life of the equipment. The front support frame 21 and the rear support frame 22 are respectively fixed on both sides of the bottom of the heat exchanger body 1. They can work together better, and when the plate heat exchanger bears a large weight or pressure, they can distribute the load evenly on the two support frames, avoiding excessive pressure on a single support frame, thereby improving the load-bearing capacity of the entire support system and enabling the plate heat exchanger to adapt to higher working pressures and larger throughput.

[0030] In a preferred embodiment, the front support frame 21 and the rear support frame 22 are symmetrical about the central axis of the heat exchanger body 1, and the front support frame 21 and the rear support frame 22 respectively cover the front and rear sides of the heat exchanger body 1.

[0031] The reinforcing plates 23 are set in two sets at the bottom of the front support frame 21 and the rear support frame 22. The interior of both sets of reinforcing plates 23 is provided with openings 231. The bottoms of the reinforcing plates 23, the front support frame 21 and the rear support frame 22 are set horizontally.

[0032] In a preferred embodiment, the front support frame 21 includes a support plate A211, a support plate B212, and a connecting piece 213. The support plates A211 and B212 are symmetrical about the connecting piece 213. One end of the connecting piece 213 is welded and fixed to the support plate B212, and the other end of the connecting piece 213 is welded and fixed to the support plate A211.

[0033] The support plate A211 includes a first fixing bolt 2110, a receiving port 2111, a second fixing bolt 2112, a force-bearing plate 2113, a reinforcing rib 2114, a support base 2115, and a mounting port 2116. The upper part of the support plate A211 is screwed to the end plate of the heat exchanger body 1 by two sets of first fixing bolts 2110, and the force-bearing plate 2113 at the bottom of the support plate A211 is screwed to the end plate of the heat exchanger body 1 by the second fixing bolt 2112.

[0034] In a preferred embodiment, a circular receiving port 2111 is provided in the middle of the support plate A211, and the receiving port 2111 is sleeved on the medium port at the end of the heat exchanger body 1; a support base 2115 is welded and fixed to the bottom of the force plate 2113.

[0035] In a preferred embodiment, the load-bearing plate 2113 and the support base 2115 are vertically distributed. The support base 2115 has two sets of mounting openings 2116 evenly provided, and the mounting openings 2116 are U-shaped. Three sets of reinforcing ribs 2114 are evenly welded between the load-bearing plate 2113 and the support base 2115.
