ある。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger having a deodorizing function in equipment having heat exchange fins for heat radiation and cooling, such as an air conditioner, a refrigerator, a dehumidifier, and an automobile.

を吸着させるものである。2. Description of the Related Art As a conventional method of deodorizing equipment having heat exchange fins such as an air conditioner and a refrigerator, a method using activated carbon has been generally used for a long time. This is to adsorb the odor components in the storage by diffusing or circulating ventilation into the fine pores on the surface of the activated carbon formed into pellets, granules or honeycomb.

分解脱臭触媒で分解するものである。[0003] Recently, there is a type using ozone. In this method, a part of the odor is decomposed by the oxidizing ability of ozone, the remaining odor is adsorbed by an ozonolysis / deodorization catalyst mainly composed of manganese oxide, and excess ozone is decomposed by the ozonolysis / deodorization catalyst.

成分を酸化分解して吸着性能を再生するものである。[0004] In addition to the above-mentioned deodorization mainly based on the adsorption function, a method of regenerating by heating with electric current has been proposed and commercialized. This is because an adsorbent and a noble metal-based oxidation catalyst are supported on the surface of a resistance heating element, and adsorption and deodorization are usually performed at normal temperature.
By heating to 00 ° C. or higher, odor components adsorbed on the surface are oxidized and decomposed to regenerate the adsorption performance.

【発明が解決しようとする課題】ところが、上記した脱
臭器のうち吸着作用を用いたものでは、以下のような問
題点がある。すなわち、活性炭を用いたものでは吸着量
が次第に増していって脱臭効果が低下してきてついには
吸着飽和となり脱臭効果がなくなり、場合によっては逆
に臭気発生源となってしまう。オゾンによる場合でも臭
気濃度が高い場合にはオゾン分解脱臭触媒に次第に臭気
が吸着していき、活性炭と同様に脱臭効果が低下してい
る。さらに、脱臭効果がなくなった時点で脱臭剤を交換
する必要がある。However, among the above-mentioned deodorizers, those using the adsorption function have the following problems. That is, in the case of using activated carbon, the amount of adsorption gradually increases and the deodorizing effect decreases, and eventually the adsorption becomes saturated and the deodorizing effect is lost, and in some cases, it becomes a source of odor. Even when using ozone, when the odor concentration is high, the odor is gradually adsorbed to the ozonolysis / deodorization catalyst, and the deodorizing effect is reduced similarly to activated carbon. Further, when the deodorizing effect is lost, it is necessary to replace the deodorant.
【０００７】また、エアコン、冷蔵庫等のように実際の
商品に搭載された形では空間速度（ＳＶ値）が大き過ぎ

当な担体で大きなハニカムを成型しなくてはならず、コ
ストの高いものとなってしまう。Further, in a form mounted on an actual product such as an air conditioner or a refrigerator, the space velocity (SV value) is too large, so that a sufficient contact time between the odor gas and the deodorant cannot be obtained. The odor removal rate is low, and sufficient deodorizing performance has not been obtained. It is sufficient to increase the deodorizing performance by reducing the space velocity, but in order to do so, it is necessary to mold a large honeycomb with the adsorbent itself or an appropriate carrier, resulting in high cost.
【０００８】また、通電による加熱再生を用いた脱臭方
法においては脱臭剤を交換する必要がないが、加熱再生
のためには脱臭素子をおよそ３００℃以上に昇温させる
必要があり、周囲の温度が不必要に上昇してしまった
り、安全面においても危険性が高い。In the deodorizing method using the heat regeneration by energization, it is not necessary to replace the deodorant, but for the heat regeneration, it is necessary to raise the temperature of the deodorizing element to about 300 ° C. or more. Is unnecessarily elevated, and there is a high risk in terms of safety.

が点灯している間でないと脱臭効果はない。Also, in the device disclosed in Japanese Patent Application Laid-Open No. 62-255741, since the contact area is small, sufficient contact time between the odor gas and the photocatalyst layer cannot be obtained. Deodorizing performance cannot be obtained. Furthermore, since the photocatalyst itself does not have good odor adsorbing properties, the deodorizing effect is not obtained unless the germicidal lamp is turned on.

Therefore, oxidation efficiency is improved and tobacco

It is a comparison of the adsorption performance for acetic acid and dimethyl sulfide, which is a gas that is difficult to adsorb. The measuring method is as follows. 4 g of powder of the adsorbent or the normal temperature oxidation catalyst is placed in a 27-liter closed container, and the initial concentration is 170 (ppm), 65 (ppm), respectively.
After the gas is sealed to 140 (ppm) and 100 (ppm), the fin is turned so that the gas circulates in the powder. The time change of the gas concentration in the container at this time was measured by a gas sensor.

なるという大きな欠点がある。In particular, Cu-ZSM5 showed excellent adsorption performance. Titanium oxide, which is a room temperature oxidation catalyst, has a moderate adsorption performance with the present study gas, but hardly adsorbs with sulfur compound-based gases such as dimethyl sulfide and neutral gas such as acetaldehyde. Adsorption performance is poor. In addition, manganese oxide and copper oxide, which have been conventionally used as ordinary temperature catalysts, are also difficult to adsorb to dimethyl sulfide and acetaldehyde, and have a major drawback that water is poisoned.

No deodorizing speed is obtained. Further, since the odor component adsorbed by the action of the room temperature oxidation catalyst is decomposed in the room temperature range, it is maintenance-free. Furthermore, since a heat exchanger is applied as a carrier, a separate carrier is not required, and cost can be reduced. Further, since the lamp that emits ultraviolet rays is disposed, the oxidation ability is improved, so that the tar can be decomposed in the tobacco, and at the same time, the ability of the bactericidal action is increased, and the occurrence of mold in the heat exchanger can be suppressed.
