Description

Technical Field

[0001] This utility model relates to the field of water circuit device technology, specifically a water circuit replacement device for a gas-fired heating hot water boiler plate. Background Technology

[0002] As is well known, in existing technologies, wall-hung boilers are used for bathroom and heating. In the heating system, the circulating water is repeatedly heated during the circulation process, thereby continuously outputting heat to the building and providing a heat source for the building. In the bathroom system, tap water is heat-exchanged through the plate heat exchanger circuit and then provides hot water to the user. The plate heat exchanger circuit module is a key component of the internal water circuit system of the wall-hung boiler, which includes an inlet valve, an outlet valve, and a plate heat exchanger, and integrates functions such as water circuit switching, water replenishment, and detection of water flow in the shower.

[0003] A search revealed a gas-fired heating and hot water boiler plate heat exchanger device (publication number CN214038973U). Existing plate heat exchangers mainly consist of several plates for heat exchange, with through-holes for water flow. Gaps exist between the plates, forming water flow channels for heat exchange. However, in practical use, problems easily arise when water is injected due to the gaps between the plates. When water flows directly through the through-holes, the gaps cause irregular impacts and disturbances, resulting in noise. This noise interferes with the operating environment, necessitating improvements to optimize performance. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a water circuit replacement device for gas-fired heating and hot water boiler plates, which effectively reduces the noise generated by water flow directly impacting through holes and gaps.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas-fired heating hot water boiler plate heat exchanger device, comprising a plate heat exchanger body, a shell installed at the inlet of the plate heat exchanger body, the shell being hollow inside and connected to the inlet, the inlet end of the shell being lower than the inlet of the plate heat exchanger body, in use, water enters the shell from the inlet end of the shell, and when the water level reaches the height of the inlet, it flows into the plate heat exchanger body, thereby reducing the noise generated by water directly flowing into the plate heat exchanger body.

[0008] Furthermore, a buffer pad facing the water inlet is fixedly installed inside the housing.

[0009] Furthermore, a flange is provided at the water inlet end.

[0010] Furthermore, a flange is installed at the outlet of the plate heat exchanger body.

[0011] Furthermore, the plate heat exchanger body includes clamping plates disposed at both ends, and a plurality of heat exchange plates installed between the clamping plates at both ends.

[0012] Furthermore, the plate has through holes for water flow.

[0013] Furthermore, the clamps at both ends are connected by bolts and nuts.

[0014] Furthermore, rubber rings are provided between the plates and between the plates and the clamping plate.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a gas-fired heating hot water boiler plate water exchange device, which has the following beneficial effects:

[0017] This gas-fired heating and hot water boiler plate heat exchanger device features a hollow shell at the inlet of the plate heat exchanger. The inlet end of the shell is lower than the inlet, and the two are not directly opposite each other. Therefore, water entering the shell does not directly impact the plate heat exchanger; instead, it slowly accumulates inside the shell, causing the liquid level to rise until it reaches the inlet height before flowing smoothly into the heat exchanger. This effectively reduces noise generated by direct water flow impacting the through-holes and gaps, significantly optimizing the operating environment of the plate heat exchanger and providing users with a quieter experience.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-8 This utility model discloses a plate heat exchanger device for a gas-fired heating and hot water boiler. The plate heat exchanger body includes clamping plates 1 at both ends and several heat exchange plates 3 installed between the clamping plates 1. The clamping plates 1 are connected by bolts 2 and nuts 13. Through holes 8 for water flow are provided on the plates 3. Gaps exist between the plates, and these gaps and through holes form water flow channels. Corresponding textures (not shown in the figure) are provided on both sides of the plates. For those skilled in the art, the textures on both sides of the plates 3 are known technology, and these textures are used to improve heat exchange efficiency and effect.

[0029] Several water inlets / outlets are provided on the clamping plate 1 of the plate heat exchanger body. These include a hot water inlet 4, a cold water inlet 5, a hot water outlet 6, and a cold water outlet 7. The through holes 8 on the plate 3 correspond one-to-one with the water inlets / outlets on the clamping plate 1. In the diagram, the water inlets are located on one side of the clamping plate 1. In practice, the water inlets / outlets can be located on one side of the clamping plate 1 or on both sides of the clamping plate 1, depending on the specific application and space constraints. Flanges 11 are provided at both the hot water outlet 6 and the cold water outlet 7.

[0030] like Figure 1 and Figure 5-8As shown in the diagram, the arrows indicate the water inlet direction. A shell 10, connected to both the hot water inlet 4 and the cold water inlet 5, is mounted on the clamping plate 1. The shell 10 is hollow, and water flows through it, acting as a transition point. The transition of water within the shell 10 will be further explained below. A water inlet end 15 is provided on the shell 10, with a flange 11 at this end. The water inlet end 15 on the shell 10 is not directly opposite the hot water inlet 4 or the cold water inlet 5, and it is lower than either the inlet 4 or the inlet 5. Therefore, after entering the shell 10, the water does not directly impact the plate heat exchanger but slowly accumulates within the shell 10, causing the liquid level 12 to rise until it reaches the height of the hot water inlet 4 or the cold water inlet 5 before smoothly flowing into the main body of the plate heat exchanger. This effectively reduces the noise generated by the water directly impacting the through holes 8 and gaps. Any shape and structure of shell 10 can be used in this patent, and the size of the shell 10 is matched to the water flow velocity.

[0031] To further improve the noise reduction effect and prevent water flow from impacting the housing 10 in the initial stage of water inlet, a buffer pad 14 is fixedly installed inside the housing 10 facing the water inlet end 15. The buffer pad 14 buffers the impact of water entering the water inlet end 15, further reducing noise.

[0032] To improve sealing, rubber rings 9 are provided between plates 3 and between plates 3 and clamping plate 1.

[0033] In summary, this gas-fired heating and hot water boiler plate heat exchanger device, during use, allows water to enter the shell 10 at a stable and moderate flow rate when water is injected into the plate heat exchanger. The water gradually accumulates at the bottom of the shell 10, and when the water level 12 rises to the height of the inlet (hot water inlet 4, cold water inlet 5), the water will begin to flow into the plate heat exchanger from the inlet (hot water inlet 4, cold water inlet 5), officially starting the heat exchange process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
