阅读说明：本技术 热交换器 (Heat exchanger ) 是由 中野宽之 安东透 日下秀之 吉冈俊 于 2019-02-22 设计创作，主要内容包括：热交换器(10)具有传热单元(30),该传热单元(30)沿相对于第1方向(D1)倾斜或正交的第2方向(D2)并排形成有沿第1方向(D1)延伸的多个传热流路部(31)和多个传热辅助部(32)。这里,沿与第1方向(D1)和第2方向(D2)中的任意一方均不同的第3方向(D3)配置有多个传热单元(30),形成传热单元组(15)。此外,在该热交换器(10)中,传热单元(30)沿着第2方向(D2)被划分成上风区域(WU)和下风区域(WL)。而且,热交换器(10)在被用作蒸发器时,使制冷剂(F)流入配置于上风区域(WU)的传热流路部(31U)后,使制冷剂(F)向配置于下风区域(WL)的传热流路部(31L)流出。(The heat exchanger (10) is provided with a heat transfer unit (30), and the heat transfer unit (30) is provided with a plurality of heat transfer flow path parts (31) and a plurality of heat transfer auxiliary parts (32) which extend along a 1 st direction (D1) in parallel along a 2 nd direction (D2) which is inclined or orthogonal to the 1 st direction (D1). Here, a plurality of heat transfer units (30) are arranged in a 3 rd direction (D3) different from either the 1 st direction (D1) or the 2 nd direction (D2), forming a heat transfer unit group (15). Further, in the heat exchanger (10), the heat transfer unit (30) is divided into an upwind region (WU) and a downwind region (WL) along the 2 nd direction (D2). When the heat exchanger (10) is used as an evaporator, the refrigerant (F) is caused to flow into the heat transfer flow path section (31U) disposed in the upwind region (WU), and then the refrigerant (F) is caused to flow out into the heat transfer flow path section (31L) disposed in the downwind region (WL).)

1. A heat exchanger (10) having a heat transfer unit (30) in which a plurality of heat transfer flow path portions (31) and a plurality of heat transfer auxiliary portions (32) extending in a 1 st direction are formed side by side in a 2 nd direction (D2) that is inclined or orthogonal to the 1 st direction (D1), the heat exchanger being configured with a plurality of the heat transfer units in a 3 rd direction (D3) that is different from either the 1 st direction or the 2 nd direction,

the heat transfer unit is divided into an upwind region (WU) and a downwind region (WL) along the 2 nd direction,

when the heat exchanger is used as an evaporator, a refrigerant is caused to flow into a heat transfer passage section (31U) disposed in the upwind region, and thereafter, the refrigerant is caused to flow out into a heat transfer passage section (31L) disposed in the downwind region.

2. The heat exchanger of claim 1,

the number of heat transfer flow path portions arranged in the leeward region is larger than the number of heat transfer flow path portions arranged in the windward region.

3. The heat exchanger according to claim 1 or 2,

the heat exchanger further has a pressure reducing mechanism (25) that reduces the pressure of the refrigerant,

the refrigerant is caused to flow from the heat transfer flow path portion disposed in the upwind region into the heat transfer flow path portion disposed in the downwind region via the pressure reducing mechanism.

4. The heat exchanger according to any one of claims 1 to 3,

the heat exchanger further has an upper header (21) and a lower header (22) which are connected to the heat transfer unit from above and below along the 1 st direction, forming part of the flow path of the refrigerant.

5. The heat exchanger of claim 4,

the upwind region and the downwind region are formed by partition members (21p, 22p) disposed inside the upper header and/or the lower header.

6. The heat exchanger according to any one of claims 1 to 5,

each heat transfer unit has at least 8 or more heat transfer flow path portions, and at least 2 or more heat transfer flow path portions are disposed in the windward area.

7. The heat exchanger according to any one of claims 1 to 6,

an end portion of the heat transfer unit in the 2 nd direction is coated with a heat insulating material (I) as viewed in the 1 st direction.

8. The heat exchanger of claim 7,

in the heat transfer unit, a 1 st heat transfer auxiliary portion (32g) as one of the heat transfer auxiliary portions is formed at an end portion in the 2 nd direction as viewed in the 1 st direction,

the 1 st heat transfer auxiliary part is in a closed shape.

9. An air conditioner having the heat exchanger according to any one of claims 1 to 8 mounted thereon.
