[0002] A fresh air ventilator is a ventilation device that can discharge polluted air from a closed room to the outside while introducing natural fresh air from the outside into the closed room. The fresh air ventilator mechanically supplies and draws air to force the formation of a fresh air flow field.
[0003] Nowadays, when fresh air ventilators replace the air in a closed room, they discharge the polluted air in the room to the outside, and at the same time, the heat in the room is carried out by the air, causing the indoor temperature component to drop. Most fresh air ventilators are equipped with heaters inside to allow the natural fresh air from the outside to be introduced into the closed room while heating the air to keep the indoor temperature unchanged, which greatly increases the electricity cost of the fresh air ventilator and the use effect is not good. In order to solve the above problems, there is an urgent need for a new fresh air ventilator with a full heat recovery core structure to solve the above problems. Utility Model Content
[0004] The purpose of the present utility model is to solve the problem that the current fresh air ventilator, when replacing the air in a closed room, discharges the polluted air in the room to the outside, and also carries the heat in the room out by the air, causing the indoor temperature component to drop. Most fresh air ventilators are equipped with heaters inside, which allow the natural fresh air from the outside to be introduced into the closed room and heat the air to keep the indoor temperature unchanged, which greatly increases the electricity cost of the fresh air ventilator and the problem of poor use effect. A new fresh air ventilator with a full heat recovery core structure is proposed.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a new type of fresh air ventilator with a full heat recovery core structure, comprising a shell, a mounting frame fixedly mounted on the side wall of the shell, an indoor air inlet pipe and an indoor air outlet pipe fixedly mounted on one outer wall of the shell, an outdoor air outlet pipe and an indoor air inlet pipe fixedly mounted on the other outer wall of the shell, a partition fixedly mounted on the inner wall of the shell, and a full heat recovery component provided on the inner wall of the shell;
[0006] The full heat recovery assembly includes a first heat conducting plate and a second heat conducting plate. One side of the first heat conducting plate is fixedly mounted on the inner wall of the shell, and one side of the second heat conducting plate is fixedly mounted on the outer wall of one side of the partition.

[0009] As a further description of the above technical solution:
[0010] The heat conducting pipe passes through the through hole provided on the partition.
[0011] As a further description of the above technical solution:
[0012] The top end of the heat-conducting connecting pipe is fixedly connected to the outer wall of the heat-conducting pipe.
[0013] As a further description of the above technical solution:
[0014] A heat spreader is fixedly mounted on the other end of the heat-conducting connecting pipe, and one side of the heat spreader is fixedly mounted on the outer wall of the other side of the partition.
[0015] As a further description of the above technical solution:
[0016] The other side of the heat spreader is fixedly mounted on the inner wall of the housing, and a plurality of ventilation holes are provided on the heat spreader.
[0017] As a further description of the above technical solution:
[0018] Heat absorbing plates are fixedly mounted on the outer walls of the first heat conducting plate and the second heat conducting plate.
[0019] As a further description of the above technical solution:

[0023] As a further description of the above technical solution:
[0024] A second thermal insulation layer is provided on the outer walls of the heat-conducting pipe and the heat-conducting connecting pipe.
[0025] Compared with the existing technology, the beneficial effects of this solution are as follows:
[0026] The heat absorbed by the heat absorbing plate is guided to the heat conducting pipe by the first heat conducting plate and the second heat conducting plate, and then guided to the heat diffusion plate by the heat conducting pipe. At this time, the outside air enters the interior of the housing through the indoor inlet pipe, and the outside air contacts the heat diffusion plate arranged inside the housing, so that the outside air carries the heat on the heat diffusion plate and is guided into the room through the indoor outlet duct. Through this design, the heat recovery of the air discharged from the outside is effectively realized, and there is no need to use a heater to heat the natural fresh air outside to keep the indoor temperature unchanged, which greatly reduces the electricity cost of the fresh air exchanger and has a good use effect.
[0027] 2. This solution is provided with multiple heat absorbing plates. Several heat absorbing plates are provided on the side walls of the first heat conducting plate and the second heat conducting plate. The heat absorbing plates provided on the side walls of the first heat conducting plate and the heat absorbing plates provided on the side walls of the second heat conducting plate are intersectingly installed on the same horizontal plane, so that the indoor air can be more fully in contact with the heat absorbing plates. Through this design, it is effectively achieved that the air exported to the outside is fully in contact with several heat absorbing plates, which greatly improves the heat transfer in the air to the heat absorbing plates, avoids heat waste, and has a good use effect.

[0036] In actual application, by setting up a full heat recovery component and starting the fresh air ventilator, the indoor air enters the interior of the shell 1 from the indoor air inlet pipe 3, and can be directly discharged to the outside from the outdoor air outlet pipe 5 through the interior of the shell 1. In this process, the indoor air will pass through the space set between the heat conduction plates of the first heat conduction plate 71 and the second heat conduction plate 72, and the heat absorption plate 73 set on the first heat conduction plate 71 and the second heat conduction plate 72 absorbs the heat carried by the indoor air.
[0037] Example 2: A new type of fresh air ventilator with a full heat recovery core structure, which is different from Examples 1 and 3 in that Figure 2 As shown, a heat conducting connecting pipe 75 is fixedly mounted on the top of the second heat conducting plate 72, and a heat conducting pipe 74 is fixedly mounted on the top of the first heat conducting plate 71. The heat conducting pipe 74 passes through a through hole provided on the partition, and the top end of the heat conducting connecting pipe 75 is fixedly connected to the outer wall of the heat conducting pipe 74.

At this time, the outside air enters the interior of the shell 1 through the indoor inlet pipe 6, and the outside air comes into contact with the heat spreader 76 set inside the shell 1, so that the outside air carries the heat on the heat spreader 76 and is guided into the room through the indoor air outlet pipe 4.
[0039] Example 3: A new type of fresh air ventilator with a full heat recovery core structure, which is different from Example 1 in that Figure 1-2 As shown in Figure 3-4, a heat absorbing plate 73 is fixedly mounted on the outer walls of the first heat conducting plate 71 and the second heat conducting plate 72.

The heat absorbing plate 73 set on the first heat conducting plate 71 and the second heat conducting plate 72 absorbs the heat carried by the indoor air. The heat absorbed by the heat absorbing plate 73 is guided to the heat conducting pipe 74 through the first heat conducting plate 71 and the second heat conducting plate 72, and then guided from the heat conducting pipe 74 to the heat diffusion plate 76. At this time, the outside air enters the interior of the shell 1 through the indoor inlet pipe 6, and the outside air contacts the heat spreader 76 provided inside the shell 1, so that the outside air carries the heat on the heat spreader 76 and is guided into the room through the indoor air outlet pipe 4.
