Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner production, in particular to a heat exchanger provided with a diverter plate. Background Art

[0002] At present, air conditioners are common household appliances in people's daily lives. They are widely used because of their convenience. Conventional air conditioners used for heating usually consist of burners, heat exchangers, smoke hoods and other components. The heat exchanger of the air conditioner is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid so that the fluid temperature reaches the index specified by the process flow. The heat exchanger is widely used in the boiler HVAC field as a heat transfer device. Usually, the heat exchanger includes components such as a heat exchange monolithic plate, a back plate and a front plate.

[0003] However, in the existing heat exchanger structure, most of the heat exchangers directly discharge smoke to the smoke hood, which then guides the smoke hood to flow into the opening below the back plate. As a result, it is easy for the smoke hood to have too high a temperature in the area in the direction where the high-temperature smoke directly discharges. The sheet metal on the back of the air conditioner body is relatively close to the smoke hood, which leads to a large temperature difference between the smoke hood and the sheet metal on the back of the body. The temperature of the exposed sheet metal on the back of the body is relatively high due to radiation heat transfer, which increases the safety hazard. At the same time, since the heat exchanger radiates more heat to the outside, the heat exchange efficiency of the heat exchange system inside the air conditioner body is reduced.

[0004] Therefore, there is an urgent need to provide a heat exchanger with a splitter plate to solve the shortcomings of the prior art. Summary of the invention

[0005] The utility model aims to provide a heat exchanger with a splitter plate to solve the technical defects in the prior art.

[0006] In order to achieve the purpose of this utility model, the technical solution adopted is:

[0007] Provided is a heat exchanger provided with a diverter plate, comprising a front end plate, a heat exchange monolith installed on the front end plate and having a high-temperature flue gas outlet, a back plate arranged on a side of the heat exchange monolith away from the front end plate, a through hole opened on the back plate, a diverter plate fixed on the back plate and having a diverter hole, and a secondary heat exchanger inlet fixed on the back plate and located at the lower side of the bottom of the diverter plate; the high-temperature flue gas outlet extends through the through hole in the direction of the diverter plate to between the back plate and the diverter plate; the diverter hole and the high-temperature flue gas outlet are staggered.

[0008] Preferably, the longitudinal cross-section of the diverter plate is I-shaped.

[0009] Preferably, the diverter plate includes a rectangular main body portion and a bent portion extending outwardly from a long axis side of the main body portion.

[0010] Preferably, the diverter hole comprises a first diverter hole opened in the main body and a second diverter hole arranged to penetrate both the main body and the bent portion, and the second diverter hole is arranged to be spaced apart from the first diverter hole.

[0011] Preferably, the first diversion hole and the high-temperature smoke outlet are both circular in shape.

[0012] Compared with the related art, the utility model provides a heat exchanger with a diverter plate, comprising a front end plate, a heat exchange single plate installed on the front end plate and having a high-temperature flue gas outlet, a back plate arranged on the side of the heat exchange single plate away from the front end plate, a through hole opened on the back plate, a diverter plate fixed on the back plate and having a diverter hole, and a secondary heat exchanger inlet fixed on the back plate and located on the lower side of the bottom of the diverter plate; the high-temperature flue gas outlet extends through the through hole toward the diverter plate to between the back plate and the diverter plate; the diverter hole and the high-temperature flue gas outlet are staggered. By setting the diverter plate, the high-temperature gas discharged from the heat exchanger will be discharged after being diverted through the diverter holes on the diverter plate, and the high-temperature gas discharged after being diverted by the diverter plate will not directly rush to the external smoke hood, thereby reducing the temperature of the external smoke hood, thereby reducing the temperature difference between the external smoke hood and the back sheet metal of the fuselage near the smoke hood, and greatly reducing the radiation heat transfer of the smoke hood to the back sheet metal of the fuselage, avoiding the situation where the back sheet metal of the fuselage is overheated, thereby improving the safety and service life of the air conditioner using the heat exchanger. In addition, the setting of the diverter plate also reduces the radiation heat transfer of the heat exchanger to the outside world, thereby improving the utilization rate of heat inside the air conditioner body.
