Embodiment 1

[0026] refer to figure 1 and figure 2 , this embodiment is an integral fresh air air conditioner in which the foldable heat exchanger is placed vertically in the middle of the box. It consists of a foldable heat exchanger 1 and its upper cover box 5, lower cover box 6, sealing plate A7 and sealing plate B8, The box body 2 of the air conditioner and its indoor unit 3, outdoor unit 4, etc. are composed. The box body 2 of the air conditioner is in the shape of a square box, which is closed by a top plate 201, a bottom plate 202, a front plate 203, a rear plate 204, a left plate 205, and a right plate 206. The folding heat exchanger 1 is parallel to the front plate 203 and the The rear plate 204 is vertically placed in the box body 2, and the upper cover box 5 and the lower cover box 6 are respectively placed at the upper end and the lower end thereof, respectively covering the top and bottom openings of the folding groove of the folding heat exchanger 1, and the upper cover box...

Embodiment 2

[0030] refer to Figure 4 , this embodiment is an integrated fresh air air conditioner with an indoor air outlet placed on the top of the box. Compared with Embodiment 1, the upper cover box 5 of the foldable heat exchanger 1 extends forward to the front of the top plate 201 of the box body 2, and a strip-shaped tuyere is opened at the matching place between the top plate 201 and the upper cover box 5. The wind can be sucked into the heat exchanger from this tuyere; the structure and size of the sealing plate A7 and the sealing plate B8 are also changed accordingly to ensure that the gap produced by the deformation of the upper cover box 5 can be closed. In this way, when the air conditioner is installed across the wall, the wall can be prevented from blocking the air outlet.

Embodiment 3

[0032] refer to Figure 5 and Figure 6 , this embodiment is an integral fresh air conditioner with a foldable heat exchanger installed close to the bottom of the box. Compared with Embodiment 1, the foldable heat exchanger 1 and the bottom plate 202 of the box 2 are placed approximately parallel to the bottom plate 202 of the box 2 At the bottom, the end air outlet of the folding heat exchanger 1 in the front chamber is placed below the air outlet of the indoor unit 3, the panel air outlet faces the bottom plate 202, and there is an air outlet at the matching place of the bottom plate 202; its end air outlet in the rear room is located Near the air inlet of the outdoor unit 4, the panel air outlet faces the top plate 201, and the upper cover box 5 is installed on the panel air outlet after the appropriate size and covers the panel air outlet, and the upper cover box 5 is provided at the position close to the left and right panels of the cabinet to enter the fresh air. orific...

Abstract

The invention discloses a folding heat exchanger and an integral fresh air conditioner thereof. The integral fresh air conditioner comprises the folding heat exchanger, an upper cover box, a lower cover box, a sealing plate A and a sealing plate B of the folding heat exchanger, a box body of the air conditioner, an indoor unit and an outdoor unit of the air conditioner and the like, and a corrugated heat exchange core body formed by continuously pressing thin plates and panels around the corrugated heat exchange core body form the flat folding heat exchanger. Air openings are formed in the two ends, a front panel and a rear panel of the folding heat exchanger, the upper cover box and the lower cover box cover the air openings in the top and the bottom of the folding heat exchanger correspondingly and are vertically arranged in the box body, the sealing plate A and the sealing plate B seal gaps between the upper cover box and the box body and between the lower cover box and the box body, air holes communicating with the outside of the box body are formed in the proper positions, close to the box body, of the upper cover box and the lower cover box, and the indoor unit arranged in a front chamber of the box body and the outdoor unit arranged in a rear chamber of the box body are connected into a whole through a connecting pipe. The folding heat exchanger is small in size, light in weight, high in heat exchange efficiency, high in cost performance, safe, reliable and convenient to install and maintain.

Description

technical field [0001] The invention mainly relates to the technical field of air conditioning equipment, in particular to a foldable heat exchanger and an integrated fresh air conditioner. Background technique [0002] In my country, the use of flammable refrigerants with low greenhouse effect potential (GWP) such as R290 in small air conditioners will further accelerate the process of replacing existing high-GWP refrigerants such as R410A and R22; on the other hand, people are concerned about the health of the indoor air environment. The requirements are getting higher and higher, and the fresh air ventilation function with low energy consumption has gradually become the standard configuration of air conditioners. For this reason, Chinese patent 202020470589.2 proposes a safe and reliable integrated room air conditioner that meets the concepts of environmental protection, energy saving and health, and is especially suitable for use with low-GWP flammable refrigerants, and h...
