以往之冷凍冷藏庫的冷卻器由以下的構件所構成,散熱片管式冷卻器,係由冷媒在內部流動的導熱管、及在該導熱管的管軸方向彼此隔著間隔下以貫穿導熱管的形式所固定之平板狀散熱片所構成;及螺旋式冷卻器,係由與上述一樣的導熱管、及螺旋狀地捲繞於其外周之散熱片所構成;螺旋狀散熱片管式熱交換器係配置於比散熱片管式冷卻器更往風向的上游側(例如參照專利文獻1)。The cooler of the conventional freezer and cold storage is composed of the following members, and the fin-and-tube cooler is a heat pipe through which the refrigerant flows, and a heat transfer pipe is interposed between the heat transfer pipes in the tube axis direction. a flat fin-shaped fin fixed in the form; and a spiral cooler composed of the same heat pipe as described above and a heat sink spirally wound around the outer circumference thereof; the spiral heat sink tube type heat exchange The device is disposed on the upstream side in the wind direction of the fin tube cooler (see, for example, Patent Document 1).
[專利文獻][Patent Literature]
[專利文獻1]特開2003-313947號公報(申請專利範圍,第1圖至第2圖)[Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-313947 (Application No. Patent No. 1, FIG. 2 to FIG. 2)
可是,在上述之以往的冷凍冷藏庫,配置於比散熱片管式冷卻器更往風向之上游側的螺旋狀散熱片管式冷卻器遠比散熱片管式冷卻器昂貴。近年來,雖然要求節能性,但是同時亦因售價降低的影響,亦要求降低成本,若使用螺旋狀散熱片管式熱交換器,相對費用的節能性效果降低,而難導入量產。However, in the conventional refrigerator-freezer described above, the spiral fin-and-tube cooler disposed on the upstream side of the fin-and-tube cooler in the wind direction is much more expensive than the fin-and-tube cooler. In recent years, although energy saving is required, it is also required to reduce the cost due to the effect of lowering the selling price. If a spiral fin-and-tube heat exchanger is used, the energy saving effect of the relative cost is lowered, and it is difficult to introduce mass production.
本發明係為了解決該問題點而開發的,其目的在於提供一種便宜、熱交換效率高的冷凍冷藏庫。The present invention has been made to solve this problem, and an object thereof is to provide a freezer and refrigerator which is inexpensive and has high heat exchange efficiency.
本發明的冷凍冷藏庫,包括:第1散熱片管式冷卻器,係由藉流入之冷媒冷卻周圍的導熱管、及貫穿並固定於該導熱管之複數個平板狀散熱片所構成;及第2散熱片管式冷卻器,係由藉流入之冷媒冷卻周圍的導熱管、及貫穿並固定於該導熱管之複數個平板狀散熱片所構成;第2散熱片管式冷卻器係比第1散熱片管式冷卻器小型,並配置於比該第1散熱片管式冷卻器更往空氣流動的上游側。The freezer-refrigerator according to the present invention includes: a first fin-and-tube cooler configured to cool a surrounding heat pipe by a refrigerant flowing in, and a plurality of flat fins penetrating and fixed to the heat pipe; and 2 The heat sink tube cooler is composed of a heat pipe that flows through the refrigerant flowing in, and a plurality of flat fins that are inserted through and fixed to the heat pipe; the second heat sink tube cooler is the first one. The fin-and-tube cooler is small and disposed on the upstream side of the air flow of the first fin-and-tube cooler.
在本發明,因為將第2散熱片管式冷卻器配置於比第1散熱片管式冷卻器更往空氣流動的上游側,所以因冷凍冷藏庫的動作所產生之霜的附著位置主要為第2散熱片管式冷卻器,可使對第1散熱片管式冷卻器之霜的附著量降低。隨著,第1散熱片管式冷卻器之平板狀散熱片間不會被霜阻塞,可抑制氣流之熱交換效率的降低,而可提供便宜的冷凍冷藏庫。In the present invention, since the second fin-and-tube cooler is disposed on the upstream side of the air flow of the first fin-and-tube cooler, the attachment position of the frost due to the operation of the freezer is mainly 2 The heat sink tube cooler can reduce the amount of frost applied to the first heat sink tube cooler. As the flat fins of the first fin-and-tube cooler are not blocked by frost, the heat exchange efficiency of the airflow can be suppressed, and an inexpensive freezer can be provided.

The vegetable compartment 5 is placed at the lowermost stage, and the freezing compartment 4 is placed thereon. Further, the arrangement of the chambers provided in the body 1 is not limited. In the opening of the refrigerator compartment 2, for example, the left and right door type doors 6 are attached. Pull-out doors 7, 8, 9, and 10 are provided, for example, in the opening portions of the switching chamber 3, the ice making chamber 22, the freezing chamber 4, and the vegetable compartment 5. Further, although the door 6 of the refrigerating compartment 2 is of a left and right type, it may be a single door type.
壓縮機11設置於本體1之背面的最下部。壓縮機11是構成本體1所具有之冷凍循環的一元件,具有壓縮冷凍循環內之冷媒的作用。利用壓縮機11所壓縮之冷媒在凝結器(未圖示)凝結,凝結之狀態的冷媒利用毛細管(未圖示)降壓。The compressor 11 is disposed at the lowermost portion of the back surface of the body 1. The compressor 11 is an element constituting the refrigeration cycle of the body 1, and has a function of compressing the refrigerant in the refrigeration cycle. The refrigerant compressed by the compressor 11 is condensed in a condenser (not shown), and the refrigerant in a condensed state is depressurized by a capillary (not shown).
冷卻器室12設置於壓縮機11的上方。第1散熱片管式冷卻器13(以下稱為「第1冷卻器13」)、第2散熱片管式冷卻器14(以下稱為「第2冷卻器14」)、冷卻用風扇15、輻射加熱器16、加熱器蓋17、具有排水孔19的排水盤18、冷凍室回流口20及冷藏室回流口21設置於該冷卻器室12。The cooler chamber 12 is disposed above the compressor 11. The first fin-and-tube cooler 13 (hereinafter referred to as "the first cooler 13"), the second fin-and-tube cooler 14 (hereinafter referred to as the "second cooler 14"), the cooling fan 15, and the radiation The heater 16, the heater cover 17, the drain pan 18 having the drain hole 19, the freezer compartment return port 20, and the refrigerating compartment return port 21 are provided in the cooler chamber 12.
第1冷卻器13由導熱管13a及貫穿並固定於導熱管13a之複數個平板狀散熱片13b所構成。第2冷卻器14與第1冷卻器13一樣,由導熱管14a及貫穿並固定於導熱管14a之複數個平板狀散熱片14b所構成。第2冷卻器14如第3圖所示,比第1冷卻器13小型,並配置於比第1冷卻器13更往空氣流動的上游側。又,對第2冷卻器14的導熱管14a,施加水之滑落性高的表面處理。例如,利用具有親疏水性或親水性的物質塗布第2冷卻器14的表面。這是用以使除霜時的霜及水分的保持量減少。The first cooler 13 is composed of a heat transfer pipe 13a and a plurality of flat fins 13b penetrating and fixed to the heat transfer pipe 13a. Similarly to the first cooler 13, the second cooler 14 is composed of a heat transfer pipe 14a and a plurality of flat fins 14b penetrating and fixed to the heat transfer pipe 14a. As shown in FIG. 3, the second cooler 14 is smaller than the first cooler 13, and is disposed on the upstream side of the air flow of the first cooler 13. Further, a surface treatment in which the water is highly slippery is applied to the heat transfer pipe 14a of the second cooler 14. For example, the surface of the second cooler 14 is coated with a substance having hydrophilicity or hydrophilicity. This is to reduce the amount of frost and moisture retained during defrosting.
第1及第2冷卻器13、14是構成本體1所具有之冷凍循環的一元件,並以同一配舌連接。該冷卻器13、14使藉上述的毛細管所減壓的冷媒蒸發,並利用該蒸發時的吸熱作用冷卻周邊。冷卻用風扇15設置於第1及第2冷卻器13、14的上方,吸入藉該第1及第2冷卻器13、14所冷卻之冷氣,再送至本體1的各室。The first and second coolers 13 and 14 are one element constituting the refrigeration cycle of the main body 1, and are connected by the same tongue. The coolers 13 and 14 evaporate the refrigerant decompressed by the capillary tube described above, and cool the periphery by the endothermic action during the evaporation. The cooling fan 15 is disposed above the first and second coolers 13 and 14, and sucks the cold air cooled by the first and second coolers 13 and 14 and sends them to the respective chambers of the main body 1.
輻射加熱器16配置於第1冷卻器13的下方,使附著於第1及第2冷卻器13、14的霜溶化。加熱器蓋17設置於第1冷卻器13與輻射加熱器16之間,該加熱器蓋17係為了使在藉輻射加熱器16對第1及第2冷卻器13、14除霜時所滴下的水不會直接淋到而設置。排水盤18設置於冷卻器室12的底部,用以接收從第1及第2冷卻器13、14所滴下的排水。該排水從設置於排水盤18之底部的排水孔19排出。The radiant heater 16 is disposed below the first cooler 13 and melts the frost adhering to the first and second coolers 13 and 14. The heater cover 17 is disposed between the first cooler 13 and the radiant heater 16, and the heater cover 17 is provided for defrosting the first and second coolers 13, 14 when the radiant heater 16 is defrosted. Water will not be set up directly. The drain pan 18 is provided at the bottom of the cooler chamber 12 for receiving the drain water dripped from the first and second coolers 13, 14. This drain is discharged from the drain hole 19 provided at the bottom of the drain pan 18.
冷凍室回流口20是冷凍室4與冷卻器室12之間的風路,冷藏室回流口21是冷藏室2與冷卻器室12之間的風路。在冷卻用風扇15運轉中,冷氣從冷凍室4朝向冷卻器室12的方向流動,在冷卻用風扇15停止運轉時,因周邊的溫度平衡,而可能產生從冷卻器室12往冷凍室4的對流。The freezer compartment return port 20 is an air path between the freezing compartment 4 and the cooler compartment 12, and the refrigerating compartment return port 21 is an air path between the refrigerating compartment 2 and the cooler compartment 12. When the cooling fan 15 is in operation, cold air flows from the freezing compartment 4 toward the cooler compartment 12, and when the cooling fan 15 is stopped, the temperature of the surroundings is balanced, and the cooling chamber 12 may be caused to flow from the cooler chamber 12 to the freezing compartment 4. convection.
在如上述所示構成的冷凍冷藏庫,在冷卻運轉中,藉第1及第2冷卻器13、14所冷卻之冷氣利用冷卻用風扇15被送入各室,再回到冷卻器室12內。藉該冷氣的循環,對配置於比第1冷卻器13更往空氣流動之上游側的第2冷卻器14之霜的附著量多,對配置於比第2冷卻器14更下游側的第1冷卻器13之霜的附著量少。In the refrigerating refrigerator configured as described above, the cooling air cooled by the first and second coolers 13 and 14 is sent to the respective chambers by the cooling fan 15 in the cooling operation, and is returned to the cooler chamber 12 . In the circulation of the cold air, the amount of frost attached to the second cooler 14 on the upstream side of the air flow of the first cooler 13 is larger, and the first one is disposed on the downstream side of the second cooler 14 . The amount of frost attached to the cooler 13 is small.
依此方式,因為將第2冷卻器14配置於比第1冷卻器13更往空氣流動之上游側,所以第2冷卻器14之霜的附著量比第1冷卻器13的更多。因而,第1冷卻器13之平板狀散熱片13b間不會被霜阻塞,而可抑制氣流之熱交換效率的降低。In this manner, since the second cooler 14 is disposed on the upstream side of the air flow of the first cooler 13 , the amount of frost adhering to the second cooler 14 is larger than that of the first cooler 13 . Therefore, the flat fins 13b of the first cooler 13 are not blocked by frost, and the heat exchange efficiency of the airflow can be suppressed from being lowered.
又,在霜未附著之冷卻運轉時,藉由追加第2冷卻器14,因為可抑制氣流之熱交換效率的降低,所以第1及第2冷卻器13、14整體的熱交換量增加,而整體上冷凍冷藏庫之耗電量的降低效果變大。進而,因為將第2冷卻器14的散熱片14b作成平板狀,所以與使用螺旋式散熱片的以往相比,可降低耗費。In addition, when the second cooler 14 is added to the cooling operation in which the frost is not attached, the heat exchange rate of the entire first and second coolers 13 and 14 is increased, and the heat exchange efficiency of the entire first and second coolers 13 and 14 is increased. As a whole, the effect of reducing the power consumption of the freezer is increased. Further, since the fins 14b of the second cooler 14 are formed in a flat shape, the cost can be reduced as compared with the conventional use of the spiral fins.
第4圖係將本發明之第2實施形態之冷凍冷藏庫的冷卻器室放大後表示的剖面圖。此外,對與第1實施形態相同的部分附加相同的符號。Fig. 4 is a cross-sectional view showing the cooler chamber of the freezer-refrigerator according to the second embodiment of the present invention in an enlarged manner. In addition, the same components as those in the first embodiment are denoted by the same reference numerals.
在第2實施形態,第2散熱片管式冷卻器14(以下稱為「第2冷卻器14」)如第4圖中所示,比第1散熱片管式冷卻器13(以下稱為「第1冷卻器13」)小型,並配置於比該第1冷卻器13更往空氣流動之上游側。又,第2冷卻器14的安裝角度相對第1冷卻器13的平板狀散熱片13b的底面傾斜成位於45度至90度之範圍。第2冷卻器14的角度配合從冷凍室回流口20及冷藏室回流口21向冷卻器室12內流入之冷氣的風向。In the second embodiment, the second fin-and-tube cooler 14 (hereinafter referred to as "second cooler 14") is larger than the first fin-and-tube cooler 13 (hereinafter referred to as "the" as shown in Fig. 4). The first cooler 13") is small and disposed on the upstream side of the air flow of the first cooler 13. Moreover, the attachment angle of the second cooler 14 is inclined in the range of 45 to 90 degrees with respect to the bottom surface of the flat fin 13b of the first cooler 13. The angle of the second cooler 14 matches the direction of the cold air flowing into the cooler chamber 12 from the freezer compartment return port 20 and the refrigerating compartment return port 21 .
因此,流入冷卻器室12內之冷氣與第2冷卻器14之平板狀散熱片14b接觸的時間比第1實施形態的長。因而,更加改善第2冷卻器14的熱交換效率,霜附著於第2冷卻器14之導熱管14a的量增加,而可向市場提供節能性優異的冷凍冷藏庫。Therefore, the time during which the cold air flowing into the cooler chamber 12 comes into contact with the flat fins 14b of the second cooler 14 is longer than that of the first embodiment. Therefore, the heat exchange efficiency of the second cooler 14 is further improved, and the amount of frost adhering to the heat transfer pipe 14a of the second cooler 14 is increased, and a freezer that is excellent in energy saving can be provided to the market.
第3實施形態Third embodiment
第5圖係將本發明之第3實施形態之冷凍冷藏庫的冷卻器室放大後表示的剖面圖。此外,對與第1實施形態相同的部分附加相同的符號。Fig. 5 is a cross-sectional view showing the cooler chamber of the freezer-refrigerator according to the third embodiment of the present invention in an enlarged manner. In addition, the same components as those in the first embodiment are denoted by the same reference numerals.
在第3實施形態,第2散熱片管式冷卻器14(以下稱為「第2冷卻器14」)如第5圖中所示,比第1散熱片管式冷卻器13(以下稱為「第1冷卻器13」)小型,並配置於比該第1冷卻器13更往空氣流動之上游側。又,第2冷卻器14的安裝角度係為了配合從冷凍室回流口20及冷藏室回流口21向冷卻器室12內流入之冷氣的風向,而相對第1冷卻器13的平板狀散熱片13b傾斜成位於45度至90度之範圍。In the third embodiment, the second fin-and-tube cooler 14 (hereinafter referred to as "second cooler 14") is shown in Fig. 5 as compared with the first fin-and-tube cooler 13 (hereinafter referred to as " The first cooler 13") is small and disposed on the upstream side of the air flow of the first cooler 13. Further, the attachment angle of the second cooler 14 is a flat fin 13b that is opposed to the first cooler 13 in order to match the direction of the cold air flowing into the cooler chamber 12 from the freezer compartment return port 20 and the refrigerating compartment return port 21. Tilt to a range of 45 to 90 degrees.
又,根據附著於第2冷卻器14的霜在冷氣與平板狀散熱片14b之前緣碰撞之範圍易成長的現象,而擴大平板狀散熱片14b的前緣面積。即,將平板狀散熱片14b的形狀作成例如八角形形狀,以促進是第2冷卻器14本來之功能的著霜。In addition, the frost adhering to the second cooler 14 is likely to grow in a range in which the cold air collides with the front edge of the flat fins 14b, and the front edge area of the flat fins 14b is enlarged. In other words, the shape of the flat fins 14b is, for example, an octagonal shape to promote the frost which is the original function of the second cooler 14.
因此,附著於第2冷卻器14之八角形的平板狀散熱片14b之霜的量更增加,而可向市場提供節能性優異的冷凍冷藏庫。Therefore, the amount of frost attached to the octagonal flat fin 14b of the second cooler 14 is further increased, and a refrigerated refrigerator excellent in energy saving can be provided to the market.
此外,雖然將第2冷卻器14之平板狀散熱片14b的形狀作成八角形,但是未限定如此,例如,該平板狀散熱片14b的形狀亦可是橢圓形或新月形。Further, although the shape of the flat fins 14b of the second cooler 14 is octagonal, the shape is not limited thereto. For example, the flat fins 14b may have an elliptical shape or a crescent shape.
