Description
本發明係關於一種溫度調節裝置，尤指設於引擎冷卻氣流之進氣端，並依據引擎啟動階段之溫度變化將進氣孔調整為通暢或遮蔽者。The invention relates to a temperature regulating device, in particular to an air inlet end of an engine cooling airflow, and adjusts the air inlet hole to be unobstructed or shielded according to the temperature change of the engine starting phase.
按，習用機車引擎之強制散熱裝置，係透過引擎於運轉時，直接帶動散熱風扇，使周遭的冷空氣經由散熱風扇吸入導風罩內，再利用導風罩內之冷空氣對引擎進行散熱動作。換言之，當引擎一啟動，散熱風扇即隨之轉動，直至引擎停止時，散熱風扇才同步停止。由於散熱風扇上覆蓋並固定有防止異物侵入之風扇罩，且該風扇罩之進氣孔並無法變更尺寸，因此，當引擎剛啟動仍處於暖機階段時，其散熱風扇即會因引擎啟動而由風扇罩之進氣孔吸入大量冷空氣，導致引擎暖機過程延長，而無法迅速達到熱車狀態，此外，過長的暖機時間不僅容易增加油耗更會產生廢氣，使環境受到汙染。Pressing, the forced cooling device of the locomotive engine directly drives the cooling fan through the engine during operation, so that the surrounding cold air is sucked into the air hood through the cooling fan, and then the cold air in the air hood is used to dissipate heat from the engine. . In other words, when the engine is started, the cooling fan rotates until the engine stops, and the cooling fan stops synchronously. Since the cooling fan is covered and fixed with a fan cover for preventing foreign matter from entering, and the air inlet hole of the fan cover cannot be changed in size, when the engine is just started, the cooling fan is started by the engine. A large amount of cold air is sucked into the air inlet of the fan cover, which causes the engine to warm up and the hot car state cannot be quickly reached. In addition, the excessive warm-up time is not only easy to increase the fuel consumption, but also causes the exhaust gas to pollute the environment.
為解決前述缺失，故中華民國公告第I421405號專利，係揭露一種「機車引擎散熱裝置」，其係於散熱風扇電連接有溫度開關，並將該溫度開關設於引擎汽缸頭或機油箱內，當引擎汽缸頭或機油箱內之溫度大於或等於一預定值時，該溫度開關會導通使散熱風扇開啟，而當引擎汽缸頭或機油箱內之溫度小於預定值時，則溫度開關不導通，並使散熱風扇關閉。In order to solve the aforementioned shortcomings, the Republic of China Announcement No. I421405 discloses a "locomotive engine heat sink" which is electrically connected to a heat-dissipating fan and has a temperature switch disposed in the engine cylinder head or the oil tank. When the temperature in the engine cylinder head or the oil tank is greater than or equal to a predetermined value, the temperature switch is turned on to turn on the heat dissipation fan, and when the temperature in the engine cylinder head or the oil tank is less than a predetermined value, the temperature switch is not turned on. And turn off the cooling fan.
有鑑於習用機車引擎之強制散熱裝置，容易導致引擎暖機過程延長並具有油耗增加及廢氣汙染等缺失。In view of the forced cooling device of the conventional locomotive engine, it is easy to cause the engine warm-up process to be prolonged and there is a lack of fuel consumption and exhaust gas pollution.
因此，本發明之目的乃是透過可調整之風扇罩組來控制冷空氣進入冷卻氣流進氣端之時間點，以避免大量冷空氣影響引擎暖機時間，並達成降低油耗與減少廢氣排放之功效。Therefore, the object of the present invention is to control the time when cold air enters the intake end of the cooling airflow through the adjustable fan cover group, so as to avoid a large amount of cold air affecting the engine warm-up time, and achieve the effects of reducing fuel consumption and reducing exhaust gas emissions. .
為達前揭目的，本發明提供一種引擎溫度調節裝置，該裝置設於引擎冷卻氣流進氣端，並包含︰一動力源；一伸縮件，連接於該動力源；一控制模組，供偵測該引擎啟動之溫度以獲得一溫度訊號，並於溫度訊號低於一預定值時控制動力源驅動，或於溫度訊號達到預定值時控制動力源關閉；以及一風扇罩組，覆蓋於冷卻氣流進氣端，並包含一外風扇罩及一內風扇罩，該外風扇罩及內風扇罩分別設有複數進氣孔，並將該伸縮件連接於外風扇罩或內風扇罩其一，以藉動力源控制伸縮件使所連接之風扇罩移動，進而將進氣孔調整為通暢或遮蔽狀態。In order to achieve the foregoing, the present invention provides an engine temperature adjusting device, which is disposed at an intake end of an engine cooling airflow and includes: a power source; a telescopic member connected to the power source; and a control module for detecting Measuring the temperature at which the engine is started to obtain a temperature signal, and controlling the power source driving when the temperature signal is lower than a predetermined value, or controlling the power source to be turned off when the temperature signal reaches a predetermined value; and a fan cover group covering the cooling airflow The air inlet end includes an outer fan cover and an inner fan cover, wherein the outer fan cover and the inner fan cover respectively have a plurality of air inlet holes, and the extension member is connected to the outer fan cover or the inner fan cover to The power source control telescopic member moves the connected fan cover to adjust the air inlet to a smooth or shielded state.
基於上述，使風扇罩組之進氣孔於引擎未啟動時設定為通暢狀態，當引擎啟動後，若控制模組所偵測之引擎溫度低於預定值，則會驅動動力源使該動力源連動伸縮件，而使該伸縮件所連接之外風扇罩或內風扇罩移動，進而讓外風扇罩與內風扇罩之進氣孔交錯而呈遮蔽狀態，此時，外部的冷空氣無法經由進氣孔進入引擎冷卻氣流進氣端，使導風罩內之空氣量受限制而能加速引擎暖機；而當控制模組所偵測之引擎溫度達到預定值時，則會關閉動力源使連接於外風扇罩或內風扇罩之伸縮件彈性回復至初始位置，並讓外風扇罩與內風扇罩之進氣孔交疊而呈通暢狀態，使周遭冷空氣能持續吸入進氣端，以協助引擎散熱。Based on the above, the air inlet hole of the fan cover group is set to an unobstructed state when the engine is not started. When the engine is started, if the engine temperature detected by the control module is lower than a predetermined value, the power source is driven to make the power source. Linking the telescopic member to move the fan cover or the inner fan cover to be connected, so that the outer fan cover and the inner fan cover are staggered to be shielded. At this time, the external cold air cannot pass through. The air vent enters the intake end of the engine cooling airflow to limit the amount of air in the air hood to accelerate the engine warm-up; when the engine temperature detected by the control module reaches a predetermined value, the power source is turned off to make the connection The elastic member of the outer fan cover or the inner fan cover elastically returns to the initial position, and the outer fan cover overlaps with the air inlet hole of the inner fan cover to be in an unobstructed state, so that the surrounding cold air can continuously be sucked into the air inlet end to assist Engine cooling.

The telescopic member 3 is connected to the power source 2. Preferably, the power source 2 is a stepping motor or a solenoid valve, and the telescopic member 3 is a return spring; the control module 4 is configured to detect the temperature at which the engine is started. Obtaining a temperature signal, and controlling the power source 2 to drive when the temperature signal is lower than a predetermined value, or controlling the power source 2 to be turned off when the temperature signal reaches a predetermined value; the fan cover group 5 covers the intake end of the engine cooling airflow. An outer fan cover 51 and an inner fan cover 52 are provided. The outer fan cover 51 is provided with a plurality of air inlet holes 511, and the inner fan cover 52 is also provided with a plurality of air inlet holes 521, and the extension member 3 is connected to the outer fan. One of the cover 51 or the inner fan cover 52 can control the expansion/contraction member 3 to be moved by the power source 2 to move the fan cover 51 or the inner fan cover 52, and further the air intake hole 511 of the fan cover group 5 (521) Adjusted to smooth or blocking state.
其次，請仍然參閱第1~2圖所示，於本發明之一實施例中，該外風扇罩５１設有一開孔５１２，並於外風扇罩５１外環形成一第一凸塊５１３及一第二凸塊５１４，而內風扇罩５２設有對應開孔５１２之凸柱５２２，並於內風扇罩５２外環設有定位塊５２３，而能將內風扇罩５２之凸柱５２２穿設於外風扇罩５１之開孔５１２，並藉一固定件５３鎖固於凸柱５２２，使內風扇罩５２能以凸柱５２２為軸心於外風扇罩５１內樞轉，並使內風扇罩５２之定位塊５２３於外風扇罩５１的第一凸塊５１３及第二凸塊５１４之間限位移動。In the embodiment of the present invention, the outer fan cover 51 is provided with an opening 512, and a first protrusion 513 and a outer ring of the outer fan cover 51 are formed. The second protrusion 514, the inner fan cover 52 is provided with a protrusion 522 corresponding to the opening 512, and the outer ring of the inner fan cover 52 is provided with a positioning block 523, and the protrusion 522 of the inner fan cover 52 can be inserted through The opening 512 of the outer fan cover 51 is locked to the protrusion 522 by a fixing member 53 so that the inner fan cover 52 can pivot in the outer fan cover 51 with the protrusion 522 as an axis, and the inner fan cover 52 is closed. The positioning block 523 is limited to move between the first protrusion 513 and the second protrusion 514 of the outer fan cover 51.
接著，請繼續參閱第3圖所示，係本發明裝置初始狀態之示意圖，該風扇罩組５係覆蓋於引擎之散熱風扇６，且於引擎未啟動時，內風扇罩５２之定位塊５２３係抵靠於外風扇罩５１之第一凸塊５１３，使外風扇罩５１與內風扇罩５２之進氣孔５１１（５２１）交疊而預設為通暢狀態。Next, please refer to FIG. 3, which is a schematic diagram of the initial state of the device of the present invention. The fan cover group 5 covers the cooling fan 6 of the engine, and when the engine is not started, the positioning block 523 of the inner fan cover 52 is Abutting against the first protrusion 513 of the outer fan cover 51, the outer fan cover 51 overlaps the air inlet hole 511 (521) of the inner fan cover 52 to be preset in an unobstructed state.
當引擎啟動後，控制模組４隨即偵測引擎溫度，若所獲得之溫度訊號低於預定值時，將控制動力源２驅動，使步進馬達轉動或使電磁閥通電而拉動伸縮件３（如第4圖所示），讓連結於伸縮件３之定位塊５２３移動而抵靠於第二凸塊５１４，使外風扇罩５１與內風扇罩５２之進氣孔５１１及５２１交錯而呈遮蔽狀態，此時，外部的冷空氣無法經由進氣孔５１１（５２１）進入引擎冷卻氣流進氣端，使導風罩內之空氣量受限制而能加速引擎暖機。When the engine is started, the control module 4 immediately detects the engine temperature. If the obtained temperature signal is lower than the predetermined value, the power source 2 is controlled to drive, the stepping motor is rotated or the solenoid valve is energized to pull the telescopic member 3 ( As shown in FIG. 4, the positioning block 523 coupled to the telescopic member 3 is moved to abut against the second protrusion 514, and the outer fan cover 51 and the air inlet holes 511 and 521 of the inner fan cover 52 are interlaced to form a shadow. In this state, at this time, the external cold air cannot enter the intake port of the engine cooling airflow through the air inlet hole 511 (521), so that the amount of air in the air hood is restricted to accelerate the engine warming up.
而當控制模組４所偵測之引擎溫度達到預定值時，則會控制動力源２關閉，使步進馬達停止轉動或使電磁閥斷電進而讓伸縮件３失去拉力而彈性回復至初始位置（如第5圖所示），使連結於伸縮件３之定位塊５２３移動回第一凸塊５１３之位置，並讓外風扇罩５１與內風扇罩５２之進氣孔５１１（５２１）交疊而呈通暢狀態，使周遭冷空氣能持續吸入進氣端，以協助引擎散熱。When the engine temperature detected by the control module 4 reaches a predetermined value, the power source 2 is controlled to be turned off, the stepping motor is stopped to rotate or the electromagnetic valve is de-energized, and the expansion member 3 loses the pulling force and elastically returns to the initial position. (As shown in FIG. 5), the positioning block 523 coupled to the telescopic member 3 is moved back to the position of the first projection 513, and the outer fan cover 51 is overlapped with the air inlet hole 511 (521) of the inner fan cover 52. In a smooth state, the surrounding cold air can continue to be sucked into the intake end to assist the engine to dissipate heat.
值得一提的是，位於外風扇罩５１及內風扇罩５２之外環能分別增設複數通風孔５１５及５２４（請回顧第2圖），並能於外風扇罩５１與內風扇罩５２之進氣孔５１１及５２１交錯而呈遮蔽狀態時，使外風扇罩５１與內風扇罩５２之通風孔５１５及５２４未完全交錯而形成一孔隙５４（如第6圖所示），以避免引擎進氣端完全密閉而造成引擎過熱或散熱不及。It is worth mentioning that a plurality of ventilation holes 515 and 524 can be added to the outer ring cover 51 and the inner fan cover 52 (refer to FIG. 2), and the outer fan cover 51 and the inner fan cover 52 can be inserted. When the air holes 511 and 521 are staggered and shielded, the outer fan cover 51 and the vent holes 515 and 524 of the inner fan cover 52 are not completely staggered to form an aperture 54 (as shown in FIG. 6) to avoid engine air intake. The end is completely sealed, causing the engine to overheat or dissipate heat.
是以，使用本發明之裝置１顯然能達成如下之功效︰ 1. 本發明之裝置１能依據引擎工作溫度調整風扇罩組５之進氣孔５１１（５２１），使引擎於剛啟動尚處於冷車階段且溫度低於工作溫度時，將風扇罩組５之進氣孔５１１（５２１）調整遮蔽狀態，藉此阻斷冷卻氣流進入引擎，縮短引擎提升至工作溫度之時間，進而降低油耗並減少引擎廢氣排放，並於引擎達到工作溫度時，使風扇罩組５之進氣孔５１１（５２１）回復通暢狀態，讓冷卻氣流得以進入引擎以協助散熱。 2. 本發明之風扇罩組５其進氣孔５１１（５２１）係預設為通暢狀態，故能避免裝置１故障時，風扇罩組５之進氣孔５１１（５２１）呈現密閉狀態而影響引擎散熱，此外，該外風扇罩５１及內風扇罩５２外環所設之通風孔５１５（５２４），能於進氣孔５１１（５２１）呈遮蔽狀態時，保留有一孔隙５４，以避免引擎過熱或散熱不及。Therefore, the device 1 of the present invention can obviously achieve the following effects: 1. The device 1 of the present invention can adjust the air inlet hole 511 (521) of the fan cover group 5 according to the operating temperature of the engine, so that the engine is still cold at the start of the operation. When the vehicle phase is lower than the working temperature, the air inlet hole 511 (521) of the fan cover group 5 is adjusted to the shielding state, thereby blocking the cooling airflow from entering the engine, shortening the time for the engine to rise to the working temperature, thereby reducing fuel consumption and reducing The engine exhausts and when the engine reaches the operating temperature, the air inlet 511 (521) of the fan cover group 5 is returned to an unobstructed state, allowing the cooling airflow to enter the engine to assist in heat dissipation. 2. The air intake hole 511 (521) of the fan cover group 5 of the present invention is preset to be in an unobstructed state, so that when the device 1 fails, the air inlet hole 511 (521) of the fan cover group 5 is sealed and the engine is affected. The heat dissipation, in addition, the outer fan cover 51 and the outer ring of the inner fan cover 52 are provided with ventilation holes 515 (524), and when the air inlet hole 511 (521) is shielded, a hole 54 is retained to prevent the engine from overheating or Less heat.
